In this regard, as described above, FIG. 1C shows a configuration in which an electronic device is interfaced with a plurality of base stations or network entities according to an embodiment.

Referring to FIG. 1C , 4G/5G deployment options are shown. In relation to 4G/5G deployment, when multi-RAT of 4G LTE and 5G NR is supported and in non-standalone (NSA) mode, it can be implemented as EN-DC of option 3 or NGEN-DC of option 5. On the other hand, if multi-RAT is supported and in standalone (SA) mode, it may be implemented as NE-DC of option 4. In addition, when single RAT is supported and in standalone (SA) mode, it may be implemented as NR-DC of option 2.

Regarding the base station type, the eNB is a 4G base station, also called an LTE eNB, and is based on the Rel-8 - Rel-14 standard. On the other hand, ng-eNB is an eNB capable of interworking with 5GC and gNB, also called eLTE eNB, and is based on the Rel-15 standard. In addition, gNB is a 5G base station interworking with 5G NR and 5GC, also called NR gNB, and is based on the Rel-15 standard. In addition, en-gNB is a gNB capable of interworking with EPC and eNB, also called NR gNB, and is based on the Rel-15 standard. Regarding the Dual Connectivity (DC) type, option 3 indicates E-UTRA-NR Dual Connectivity (EN-DC). On the other hand, option 7 represents NG-RAN E-UTRA-NR Dual Connectivity (NGEN-DC). In addition, option 4 indicates NR-E-UTRA Dual Connectivity (NE-DC). Also, option 2 indicates NR-NR Dual Connectivity (NR-DC). In this regard, the technical characteristics of the dual connection according to option 2 to option 7 are as follows.

- Option 2: Independent 5G service can be provided only with 5G system (5GC, gNB). In addition to eMBB (enhanced Mobile Broadband), URLLC (Ultra-Reliable Low-Latency Communication) and mMTC (Massive Machine Type Communication) communication are possible, and 5GC characteristics such as network slicing, MEC support, Mobility on demand, and Access-agnostic can be used. 5G full service can be provided. Initially, due to coverage limitations, it can be used as an overlay network or for a hot spot, enterprise use, and EPC-5GC interworking is required if it is out of 5G NR coverage. 5G NR full coverage may be provided, and dual connectivity (NR-DC) between gNBs may be supported using multiple 5G frequencies.

- Option 3: When only gNB is introduced into the existing LTE infrastructure. Core is EPC and gNB is an en-gNB capable of interworking with EPC and eNB. Dual connectivity (EN-DC) is supported between the eNB and the en-gNB, and the master node is the eNB. The eNB, which is the control anchor of the en-gNB, processes control signaling for network access, connection establishment, handover, etc. of the UE, and user traffic may be delivered through the eNB and/or en-gNB. This option is mainly applied in the first stage of 5G migration, as operators operating nationwide LTE networks can quickly build 5G networks with the introduction of en-gNB and minimal LTE upgrades without 5GC.

There are 3 types of Option 3, Option 3/3a/3x depending on the user traffic split method. Bearer split is applied to Option 3/3x and Option 3a is not applied. The main method is Option 3x.

- Option 3: Only the eNB is connected to the EPC and the en-gNB is only connected to the eNB. User traffic is split in the master node (eNB) and can be transmitted simultaneously to LTE and NR.

- Option 3a: Both the eNB and the gNB are connected to the EPC, and user traffic is delivered directly from the EPC to the gNB. User traffic is transmitted in LTE or NR.

- Option 3x: Option 3 and Option 3a are combined. The difference from Option 3 is that user traffic is split at the secondary node (gNB).

The advantages of Option 3 are i) that LTE can be used as a capacity booster for eMBB service, and ii) that the terminal is always connected to LTE, so even if it goes out of 5G coverage or the NR quality is deteriorated, service continuity is provided through LTE and stable Communication may be provided.

- Option 4: 5GC is introduced and it is still linked with LTE, but independent 5G communication is possible. The core is 5GC and the eNB is an ng-eNB capable of interworking with 5GC and gNB. Dual connectivity (NE-DC) is supported between the ng-eNB and the gNB, and the master node is the gNB. When 5G NR coverage is sufficiently expanded, LTE can be used as a capacity booster. There are 2 types of Option 4/4a. The main method is Option 4a.

- Option 7: 5GC is introduced and still works with LTE, so 5G communication depends on LTE. The core is 5GC and the eNB is an ng-eNB capable of interworking with 5GC and gNB. Dual connectivity (NGEN-DC) is supported between ng-eNB and gNB, and the master node is the eNB. 5GC characteristics can be used, and service continuity can still be provided with the eNB as the master node, as in Option 3, when 5G coverage is not yet sufficient. There are 3 types of Option 7, Option 7/7a/7x, depending on the user traffic split method. Bearer split is applied to Option 7/7x and Option 7a is not applied. The main method is Option 7x.

Hereinafter, a multi-communication system structure according to an embodiment and an electronic device having the same, in particular, an antenna in a heterogeneous radio system and an electronic device having the same will be described with reference to the accompanying drawings. It is apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit and essential characteristics of the present invention.

Meanwhile, detailed operations and functions of an electronic device having a plurality of antennas according to an embodiment provided with a 4G/5G wireless communication module as shown in FIG. 2A will be reviewed below.

In the 5G communication system according to an embodiment, the 5G frequency band may be a higher frequency band than the Sub6 band. For example, the 5G frequency band may be a millimeter wave band, but is not limited thereto and may be changed according to an application.

3A illustrates an example of a configuration in which a plurality of antennas of an electronic device may be disposed according to an embodiment. Referring to FIG. 3A , a plurality of antennas 1110a to 1110d may be disposed inside or on the front side of the electronic device 100 . In this regard, the plurality of antennas 1110a to 1110d may be implemented in a form printed on a carrier inside an electronic device or may be implemented in a system-on-chip (Soc) form together with an RFIC. Meanwhile, the plurality of antennas 1110a to 1110d may be disposed on the front surface of the electronic device in addition to the inside of the electronic device. In this regard, the plurality of antennas 1110a to 1110d disposed on the front side of the electronic device 100 may be implemented as transparent antennas built into the display.

Meanwhile, a plurality of antennas 1110S1 and 1110S2 may be disposed on a side surface of the electronic device 100 . In this regard, a 4G antenna is disposed on the side of the electronic device 100 in the form of a conductive member, a slot is formed in the conductive member region, and a plurality of antennas 1110a to 1110d radiate a 5G signal through the slot. can be In addition, antennas 1150B may be disposed on the rear surface of the electronic device 100 so that the 5G signal may be radiated from the rear surface.

Meanwhile, according to the present invention, at least one signal may be transmitted or received through the plurality of antennas 1110S1 and 1110S2 on the side of the electronic device 100 . Also, according to the present invention, at least one signal may be transmitted or received through the plurality of antennas 1110a to 1110d, 1150B, 1110S1 and 1110S2 on the front and/or side of the electronic device 100 . The electronic device may communicate with the base station through any one of the plurality of antennas 1110a to 1110d, 1150B, 1110S1 and 1110S2. Alternatively, the electronic device may perform multiple input/output (MIMO) communication with the base station through two or more antennas among the plurality of antennas 1110a to 1110d, 1150B, 1110S1 and 1110S2.

3B illustrates a configuration of a wireless communication unit of an electronic device operable in a plurality of wireless communication systems according to an embodiment. Referring to FIG. 3B , the electronic device includes a first power amplifier 1210 , a second power amplifier 1220 , and an RFIC 1250 . Also, the electronic device may further include a modem 400 and an application processor (AP) 500 . Here, the modem 400 and the application processor AP 500 are physically implemented on a single chip, and may be implemented in a logically and functionally separated form. However, the present invention is not limited thereto and may be implemented in the form of physically separated chips depending on the application.

Meanwhile, the electronic device includes a plurality of low noise amplifiers (LNAs) 410 to 440 in the receiver. Here, the first power amplifier 1210 , the second power amplifier 1220 , the controller 1250 , and the plurality of low-noise amplifiers 310 to 340 are all operable in the first communication system and the second communication system. In this case, the first communication system and the second communication system may be a 4G communication system and a 5G communication system, respectively.

As shown in FIG. 2B , the RFIC 1250 may be configured as a 4G/5G integrated type, but is not limited thereto and may be configured as a 4G/5G separate type according to an application. When the RFIC 1250 is configured as a 4G/5G integrated type, it is advantageous in terms of synchronization between 4G/5G circuits, as well as the advantage that control signaling by the modem 1400 can be simplified.

Meanwhile, when the RFIC 1250 is configured as a 4G/5G separate type, it may be referred to as a 4G RFIC and a 5G RFIC, respectively. In particular, when the difference between the 5G band and the 4G band is large, such as when the 5G band is configured as a millimeter wave band, the RFIC 1250 may be configured as a 4G/5G separate type. As such, when the RFIC 1250 is configured as a 4G/5G separate type, there is an advantage that RF characteristics can be optimized for each of the 4G band and the 5G band.

On the other hand, even when the RFIC 1250 is configured as a 4G/5G separate type, the 4G RFIC and the 5G RFIC are logically and functionally separated and it is also possible to be physically implemented on one chip.

Meanwhile, the application processor (AP) 1450 is configured to control the operation of each component of the electronic device. Specifically, the application processor (AP) 1450 may control the operation of each component of the electronic device through the modem 1400 .

For example, the modem 1400 may be controlled through a power management IC (PMIC) for low power operation of the electronic device. Accordingly, the modem 1400 may operate the power circuits of the transmitter and the receiver in the low power mode through the RFIC 1250 .

In this regard, when it is determined that the electronic device is in an idle mode, the application processor (AP) 500 may control the RFIC 1250 through the modem 300 as follows. For example, if the electronic device is in an idle mode, the RFIC through the modem 300 so that at least one of the first and

second power amplifiers

110 and 120 operates in the low power mode or is turned off (1250) can be controlled.

According to another embodiment, when the electronic device is in a low battery mode, the application processor (AP) 500 may control the modem 300 to provide wireless communication capable of low power communication. For example, when the electronic device is connected to a plurality of entities among a 4G base station, a 5G base station, and an access point, the application processor (AP) 1450 may control the modem 1400 to enable wireless communication with the lowest power. Accordingly, the application processor (AP) 500 may control the modem 1400 and the RFIC 1250 to perform short-distance communication using only the short-range communication module 113 even though the throughput is somewhat sacrificed.

According to another embodiment, when the remaining battery level of the electronic device is equal to or greater than a threshold, the modem 300 may be controlled to select an optimal wireless interface. For example, the application processor (AP) 1450 may control the modem 1400 to receive through both the 4G base station and the 5G base station according to the remaining battery level and available radio resource information. In this case, the application processor (AP) 1450 may receive the remaining battery level information from the PMIC and the available radio resource information from the modem 1400 . Accordingly, if the remaining battery level and available radio resources are sufficient, the application processor (AP) 500 may control the modem 1400 and the RFIC 1250 to receive through both the 4G base station and the 5G base station.

Meanwhile, the multi-transceiving system of FIG. 3B may integrate the transmitter and receiver of each radio system into one transceiver. Accordingly, there is an advantage that a circuit part integrating two types of system signals in the RF front-end can be removed.

In addition, since the front-end components can be controlled by the integrated transceiver, the front-end components can be more efficiently integrated than when the transmission/reception system is separated for each communication system.

In addition, when each communication system is separated, it is impossible to control other communication systems as necessary, or efficient resource allocation is impossible because the system delay is increased. On the other hand, the multi-transmission/reception system as shown in FIG. 2 has the advantage that it is possible to control other communication systems as necessary, and thus system delay can be minimized, so that efficient resource allocation is possible.

Meanwhile, the first power amplifier 1210 and the second power amplifier 1220 may operate in at least one of the first and second communication systems. In this regard, when the 5G communication system operates in the 4G band or the Sub6 band, the first and second power amplifiers 1220 may operate in both the first and second communication systems.

On the other hand, when the 5G communication system operates in the millimeter wave (mmWave) band, one of the first and

second power amplifiers

1210 and 1220 operates in the 4G band, and the other operates in the millimeter wave band. there is.

Meanwhile, by integrating the transceiver and the receiving unit, two different wireless communication systems can be implemented with one antenna by using an antenna for both transmitting and receiving. In this case, 4x4 MIMO can be implemented using four antennas as shown in FIG. 2 . In this case, 4x4 DL MIMO may be performed through the downlink (DL).

Meanwhile, if the 5G band is the Sub6 band, the first to fourth antennas ANT1 to ANT4 may be configured to operate in both the 4G band and the 5G band. On the other hand, if the 5G band is a millimeter wave (mmWave) band, the first to fourth antennas ANT1 to ANT4 may be configured to operate in any one of the 4G band and the 5G band. In this case, if the 5G band is a millimeter wave (mmWave) band, each of a plurality of separate antennas may be configured as an array antenna in the millimeter wave band.

Meanwhile, 2x2 MIMO can be implemented using two antennas connected to the first power amplifier 1210 and the second power amplifier 1220 among the four antennas. In this case, 2x2 UL MIMO (2 Tx) may be performed through the uplink (UL). Alternatively, it is not limited to 2x2 UL MIMO, and may be implemented with 1 Tx or 4 Tx. In this case, when the 5G communication system is implemented with 1 Tx, only one of the first and

second power amplifiers

1210 and 1220 needs to operate in the 5G band. On the other hand, when the 5G communication system is implemented as 4Tx, an additional power amplifier operating in the 5G band may be further provided. Alternatively, a transmission signal may be branched in each of one or two transmission paths, and the branched transmission signal may be connected to a plurality of antennas.

On the other hand, since a switch-type splitter or a power divider is built inside the RFIC corresponding to the RFIC 1250, there is no need for a separate component to be disposed outside, thereby improving component mountability. can Specifically, by using a single pole double throw (SPDT) type switch inside the RFIC corresponding to the controller 1250 , it is possible to select the transmitter (TX) of two different communication systems.

In addition, the electronic device operable in a plurality of wireless communication systems according to an embodiment may further include a duplexer 1231 , a filter 1232 , and a switch 1233 .

The duplexer 1231 is configured to mutually separate signals of a transmission band and a reception band. At this time, the signals of the transmission band transmitted through the first and

second power amplifiers

1210 and 1220 are applied to the antennas ANT1 and ANT4 through the first output port of the duplexer 1231 . On the other hand, signals of the reception band received through the antennas ANT1 and ANT4 are received by the low noise amplifiers 310 and 340 through the second output port of the duplexer 1231 .

The filter 1232 may be configured to pass a signal of a transmission band or a reception band and block a signal of the remaining band. In this case, the filter 1232 may include a transmit filter connected to a first output port of the duplexer 1231 and a receive filter connected to a second output port of the duplexer 1231 . Alternatively, the filter 1232 may be configured to pass only a signal of a transmission band or only a signal of a reception band according to the control signal.

The switch 1233 is configured to transmit either only a transmit signal or a receive signal. In an embodiment of the present invention, the switch 1233 may be configured in a single pole double throw (SPDT) type to separate a transmission signal and a reception signal in a time division multiplexing (TDD) method. In this case, the transmission signal and the reception signal are signals of the same frequency band, and accordingly, the duplexer 1231 may be implemented in the form of a circulator.

On the other hand, in another embodiment of the present invention, the switch 1233 is also applicable to a frequency division multiplexing (FDD: Time Division Duplex) scheme. In this case, the switch 1233 may be configured in a double pole double throw (DPDT) type to connect or block a transmission signal and a reception signal, respectively. Meanwhile, since a transmission signal and a reception signal can be separated by the duplexer 1231 , the switch 1233 is not necessarily required.

Meanwhile, the electronic device according to an embodiment may further include a modem 1400 corresponding to a control unit. In this case, the RFIC 1250 and the modem 1400 may be referred to as a first controller (or first processor) and a second controller (second processor), respectively. Meanwhile, the RFIC 1250 and the modem 1400 may be implemented as physically separate circuits. Alternatively, the RFIC 1250 and the modem 1400 may be physically or logically divided into one circuit.

The modem 1400 may control and process signals for transmission and reception of signals through different communication systems through the RFIC 1250 . The modem 1400 may be obtained through control information received from the 4G base station and/or the 5G base station. Here, the control information may be received through a physical downlink control channel (PDCCH), but is not limited thereto.

The modem 1400 may control the RFIC 1250 to transmit and/or receive a signal through the first communication system and/or the second communication system in a specific time and frequency resource. Accordingly, the RFIC 1250 may control transmission circuits including the first and

second power amplifiers

1210 and 1220 to transmit a 4G signal or a 5G signal in a specific time period. Also, the RFIC 1250 may control receiving circuits including the first to fourth low-noise amplifiers 310 to 340 to receive a 4G signal or a 5G signal in a specific time period.

The framework/library 450 may include a general-purpose framework/library 451 and a special-purpose framework/library 452 . Here, the general-purpose framework/library 451 and the special-purpose framework/library 452 may be referred to as a first framework/library 451 and a second framework/library 452 , respectively. The first framework/library 451 and the second framework/library 452 may interface with the kernel space and hardware through the first API 461 and the second API 462, respectively. Here, the second framework/library 452 may be an example software architecture that may modularize artificial intelligence (AI) functions. Using the architecture, various processing blocks of hardware implemented as a System on Chip (SoC) (eg, CPU 422, DSP 424, GPU 426, and/or NPU 428) to support operations during runtime operation of the application 470 .

The AI application may be configured to call functions defined in user space that may provide detection and recognition of a scene indicating the location in which the electronic device is currently operating. The AI application may configure the microphone and camera differently depending on whether the recognized scene is an indoor space or an outdoor space. The AI application may make a request for compiled program code associated with a library defined in the Scene Detect application programming interface (API) to provide an estimate of the current scene. Such a request may rely on the output of a deep neural network configured to provide scene estimates based on video and positioning data.

The framework/library 462 , which may be compiled code of the Runtime Framework, may be further accessible by the AI application. The AI application may cause the runtime framework engine to request a scene estimate at specific time intervals, or triggered by an event detected by the application's user interface. When estimating a scene, the runtime engine may then send a signal to an operating system such as a Linux Kernel running on the SoC.

When the AI algorithm is performed by the server support method, the electronic device may receive and transmit information related to the AI server and AI processing through the 4G/5G communication system.

Meanwhile, referring to FIGS. 1A and 2A , a 5G wireless communication system, that is, 5G new radio access technology (NR) may be provided. In this regard, as more and more communication devices require a larger communication capacity, there is a need for improved mobile broadband communication compared to the existing radio access technology. In addition, massive MTC (Machine Type Communications), which provides various services anytime, anywhere by connecting multiple devices and objects, is also one of the major issues to be considered in next-generation communication. In addition, communication system design considering reliability and latency sensitive service/terminal is being discussed. As described above, the introduction of next-generation radio access technology in consideration of eMBB (enhanced mobile broadband communication), Mmtc (massive MTC), URLLC (Ultra-Reliable and Low Latency Communication), etc. is being discussed, and in this specification, the technology is referred to as NR for convenience. . NR is an expression showing an example of 5G radio access technology (RAT).

A new RAT system including NR uses an OFDM transmission scheme or a similar transmission scheme. The new RAT system may follow OFDM parameters different from those of LTE. Alternatively, the new RAT system may follow the existing numerology of LTE/LTE-A, but may have a larger system bandwidth (eg, 100 MHz). Alternatively, one cell may support a plurality of numerologies. That is, terminals operating in different numerology may coexist in one cell.

In this regard, in the case of 4G LTE, since the maximum bandwidth of the system is limited to 20 MHz, a single sub-carrier spacing (SCS) of 15 KHz is used. However, in the case of 5G NR, since a channel bandwidth of 5 MHz to 400 MHz is supported, FFT processing complexity may increase to process the entire bandwidth through one subcarrier interval. Accordingly, the subcarrier interval used for each frequency band may be extended and applied.

Numerology corresponds to one subcarrier spacing in the frequency domain. By scaling the reference subcarrier spacing by an integer N, different numerology can be defined. In this regard, Fig. 5A shows an example of a frame structure in NR. Meanwhile, FIG. 5B shows a change in the slot length according to a change in the subcarrier spacing in NR.

An NR system can support multiple numerologies. Here, the numerology may be defined by a subcarrier spacing and a cyclic prefix (CP) overhead. In this case, the plurality of subcarrier intervals may be derived by scaling the basic subcarrier interval by an integer N (or μ). Also, although it is assumed that very low subcarrier spacing is not used at very high carrier frequencies, the numerology used can be selected independently of the frequency band. In addition, in the NR system, various frame structures according to a number of numerologies may be supported.

Hereinafter, an Orthogonal Frequency Division Multiplexing (OFDM) numerology and frame structure that can be considered in an NR system will be described. A number of OFDM numerologies supported in the NR system may be defined as shown in Table 1.

μμ	△f =2 ^m * 15 [kHz] △f =2 ^m * 15 [kHz]	Cyclic prefix(CP)Cyclic prefix (CP)
00	1515	NormalNormal
1One	3030	Normal Normal
22	6060	Normal, ExtendedNormal, Extended
33	120120	Normal Normal
44	240240	NormalNormal

NR supports multiple numerology (or subcarrier spacing (SCS)) to support various 5G services. For example, when SCS is 15kHz, it supports wide area in traditional cellular bands, and when SCS is 30kHz/60kHz, dense-urban, lower latency and a wider carrier bandwidth, and when the SCS is 60 kHz or higher, a bandwidth greater than 24.25 GHz to overcome phase noise.

The NR frequency band is defined as a frequency range of two types (FR1, FR2). FR1 is the sub 6GHz range, and FR2 is the above 6GHz range, which may mean millimeter wave (mmW).

Table 2 below shows the definition of the NR frequency band.

Frequency Range designationFrequency Range designation	Corresponding frequency range Corresponding frequency range	Subcarrier SpacingSubcarrier Spacing
FR1FR1	450MHz - 6000MHz450MHz - 6000MHz	15, 30, 60kHz15, 30, 60 kHz
FR2FR2	24250MHz - 52600MHz24250MHz - 52600MHz	60, 120, 240kHz60, 120, 240 kHz

With respect to the frame structure in the NR system, the sizes of various fields in the time domain are expressed as multiples of a specific time unit. 3A is an example of SCS of 60 kHz, and one subframe may include four slots. 1 subframe = {1,2,4} slots shown in FIG. 3 is an example, and the number of slot(s) that can be included in 1 subframe may be 1, 2, or 4. In addition, the mini-slot is It may contain 2, 4 or 7 symbols or may contain more or fewer symbols.

5B shows the subcarrier spacing of 5G NR phase I and the OFDM symbol length accordingly. Each subcarrier interval is extended by a power of 2, and the symbol length is reduced in inverse proportion to this. In FR1, subcarrier spacings of 15 kHz, 30 kHz and 60 kHz are available depending on the frequency band/bandwidth. In FR2, 60 kHz and 120 kHz can be used for the data channel, and 240 kHz can be used for the synchronization signal.

In 5G NR, a basic unit of scheduling is defined as a slot, and the number of OFDM symbols included in one slot may be limited to 14 as shown in FIG. 5A or 5B regardless of subcarrier spacing. Referring to FIG. 3B , when a wide subcarrier interval is used, the length of one slot is shortened in inverse proportion to reduce transmission delay in a radio section. In addition, in order to efficiently support ultra reliable low latency communication (uRLLC), scheduling in units of minislots (eg, 2, 4, 7 symbols) may be supported as described above in addition to scheduling in units of slots.

Considering the above-described technical features, the slots in 5G NR described herein may be provided at the same interval as the slots of 4G LTE or may be provided as slots of various sizes. As an example, the slot interval in 5G NR may be configured as 0.5 ms, which is the same as the slot interval of 4G LTE. As another example, the slot interval in 5G NR may be configured as 0.25 ms, which is a narrower interval than the slot interval of 4G LTE.

In this regard, the 4G communication system and the 5G communication system may be referred to as a first communication system and a second communication system, respectively. Accordingly, the first signal (first information) of the first communication system may be a signal (information) in a 5G NR frame with a slot interval scalable to 0.25 ms, 0.5 ms, or the like. On the other hand, the second signal (second information) of the second communication system may be a signal (information) in a 4G LTE frame with a fixed slot interval of 0.5 ms.

Meanwhile, the first signal of the first communication system may be transmitted and/or received through a maximum bandwidth of 20 MHz. On the other hand, the second signal of the second communication system may be transmitted and/or received through a variable channel bandwidth from 5 MHz to 400 MHz. In this regard, the first signal of the first communication system may be FFT-processed with a single sub-carrier spacing (Sub-Carrier Spacing, SCS) of 15 KHz.

On the other hand, the second signal of the second communication system may be FFT-processed at subcarrier intervals of 15 kHz, 30 kHz, and 60 kHz according to the frequency band/bandwidth. In this case, the second signal of the second communication system may be modulated and frequency-converted to the FR1 band and transmitted through the 5G Sub6 antenna. Meanwhile, the FR1 band signal received through the 5G Sub6 antenna may be frequency-converted and demodulated. Thereafter, the second signal of the second communication system may be IFFT-processed at subcarrier intervals of 15 kHz, 30 kHz, and 60 kHz according to the frequency band/bandwidth.

Meanwhile, the second signal of the second communication system may be FFT-processed at subcarrier intervals of 60 kHz, 120 kHz, and 240 kHz according to frequency band/bandwidth and data/synchronization channel. In this case, the second signal of the second communication system may be modulated to the FR2 band and transmitted through the 5G mmWave antenna. On the other hand, the FR2 band signal received through the 5G mmWave antenna can be frequency-converted and demodulated. Thereafter, the second signal of the second communication system may be IFFT-processed through subcarrier intervals of 60 kHz, 120 kHz, and 240 kHz according to frequency band/bandwidth and data/synchronization channel.

In 5G NR, symbol-level temporal alignment can be used for transmission schemes using various slot lengths, mini-slots, and different subcarrier spacings. Accordingly, it provides flexibility for efficiently multiplexing various communication services such as enhancement mobile broadband (eMBB) and ultra reliable low latency communication (uRLLC) in the time domain and frequency domain. Also, unlike 4G LTE, 5G NR may define uplink/downlink resource allocation at a symbol level in one slot as shown in FIG. 3 . In order to reduce hybrid automatic repeat request (HARQ) delay, a slot structure capable of transmitting HARQ ACK/NACK directly within a transmission slot may be defined. Such a slot structure may be referred to as a self-contained structure.

Unlike 4G LTE, 5G NR can support a common frame structure constituting an FDD or TDD frame through a combination of various slots. Accordingly, the transmission direction of an individual cell can be freely and dynamically adjusted according to traffic characteristics by introducing a dynamic TDD scheme.

Referring to FIGS. 7A and 7B , an electronic device that performs a transmission signal control method may be configured to include first and second antennas ANT1 and ANT2 and first and second transceiver circuits. .

In this regard, the first and second antennas ANT1 and ANT2 may be configured to be operable in the first communication system and the second communication system. The first transceiver circuit 1200a may be operatively coupled to the first antenna AN1, respectively. Also, the first transceiver circuit 1200a may be configured to be operable in the first communication system and the second communication system. Here, the first communication system may be a 4G LTE communication system, and the second communication system may be a 5G communication system. However, the first communication system and the second communication system are not limited thereto and may be changed according to applications.

Meanwhile, the second transceiver circuit 1200b may be operatively coupled to the second antenna ANT2, respectively. Also, the second transceiver circuit 1200b may be configured to be operable in the first communication system and the second communication system. Here, the first transceiver circuit 1200a and the second transceiver circuit 1200b may be configured to include a power amplifier PA, a reception amplifier LNA, and a filter. Meanwhile, the first transceiver circuit 1200a and the second transceiver circuit 1200b may be referred to as a transceiver circuit 1200 .

In this regard, the first transceiver circuit 1200a and the second transceiver circuit 1200b may be referred to as a first RF module or a second RF module, respectively. In this case, including the first RF module and the second RF module may be referred to as an RF module. Alternatively, the first transceiver circuit 1200a and the second transceiver circuit 1200b may be referred to as a first front-end module or a second front-end module, respectively. In this case, the first front-end module and the second front-end module may be referred to as a front-end module.

Meanwhile, the RFIC 1250 is operatively coupled to the first transceiver circuit 1200a and the second transceiver circuit 1200b to control the first transceiver circuit 1200a and the second transceiver circuit 1200b. can be configured to In this case, the RFIC 1250 may also include a Tx chain 0 operatively coupled to the first transceiver circuit 1200a and a Tx chain 1 operatively coupled to the second transceiver circuit 1200b.

In this regard, it may be referred to as a first transceiver circuit including Tx chain 0 and the first front-end module 1200a. Also, it may be referred to as a second transceiver circuit including Tx chain 1 and the first front-end module 1200a.

Meanwhile, the baseband processor 1400 may be operatively coupled to the first transceiver circuit 1250a and the second transceiver circuit 1250b. For example, the baseband processor 1400 may be a modem, and may be operatively coupled to the first transceiver circuit 1200a and the second transceiver circuit 1200b through the RFIC 1250 . Accordingly, the baseband processor 1400 may be configured to control the first transceiver circuit 1200a and the second transceiver circuit 1200b.

Referring to FIG. 7A , it is a case in which no hand grip occurs (No Hand Grip). In this case, the baseband processor 1400 may control to transmit the first signal of the first communication system through the first transceiver circuit 1200a and the first antenna ANT1 in the first transmission period.

Here, the first signal of the first communication system may be scheduled in units of subframes as shown in FIG. 6A as a 4G LTE signal. In addition, the first signal of the first communication system may be a 4G LTE signal and may be formed as an OFDM symbol of the basic subcarrier interval of FIG. 6B . On the other hand, the second signal of the second communication system is a 5G signal, and may support various neuterologies as shown in FIG. 6A and may be scheduled in units of mini-slots. In addition, the second signal of the second communication system may be formed of OFDM symbols having various subcarrier intervals as shown in FIG. 6B as a 5G signal.

7A and 7B , it is possible to detect whether a hand grip has occurred. In this regard, the quality of a received signal received through the corresponding antenna may be degraded according to other similar events or communication conditions other than the hand grip event. Accordingly, the baseband processor 1400 may determine the quality of a received signal received through the first antenna ANT1 and the first transceiver 1200a operating in the first communication system in the reception section. As an example, a hand grip may occur, so that transmission or reception performance of a signal through the first antenna ANT1 under the terminal may be deteriorated.

Referring to FIG. 7B , switching between the antenna and the transceiver circuit may be performed. In this regard, other antennas and different transceiver circuits may be used according to other similar events or communication conditions other than the hand grip event. In this regard, when it is determined that the quality of the received signal is degraded, the baseband processor 1400 performs the first communication system through the second transceiver 1200b and the second antenna ANT2 in the transmission section subsequent to the reception section. can be controlled to transmit a signal of

For example, a hand grip may be generated to control the signal to be transmitted through the second antenna ANT2 on the upper part of the terminal instead of the first antenna ANT1 on the lower part of the terminal. Accordingly, the baseband processor 1400 may determine whether the first antenna ANT1 is in a grip state during the reception period. Also, when it is determined that the first antenna ANT1 is in the grip state, the baseband processor 1400 may control the signal to be transmitted through the second transceiver 1200b and the second antenna ANT2 in the transmission section.

In this regard, when it is determined that the quality of the received signal is degraded, the baseband processor 1400 performs the first communication system through the second transceiver 1200b and the second antenna ANT2 in the second transmission period, which is the transmission period. can be controlled to transmit the first signal of On the other hand, the baseband processor 1400 may control to transmit the second signal of the second communication system through the first transceiver 1200a and the first antenna ANT1 in the second transmission period.

As described above, the baseband processor 1400 may control to transmit the first signal of the first communication system through the first transceiver circuit 1200a and the first antenna ANT1 in the first transmission period. For example, if it is determined that the first antenna ANT1 is in the grip state, the baseband processor 1400 transmits the first signal through the second transceiver 1200b and the second antenna ANT2 in the second transmission period, which is the transmission period. can be controlled to transmit.

Accordingly, since the 4G LTE signal is transmitted through the second antenna ANT2, which is another antenna, performance degradation may be compensated. On the other hand, the 5G signal is transmitted through the first antenna ANT1 whose performance is degraded by a hand grip or the like. However, assuming that the priority of the first signal, which is a 4G LTE signal, is higher than that of the second signal, which is a 5G signal, the 4G LTE signal may be transmitted through the second antenna ANT2, which is another antenna. In this regard, since a phenomenon such as a call drop may occur when the 4G LTE signal is disconnected, a higher priority may be given.

Also, when it is determined that the quality of the received signal is deteriorated, the baseband processor 1400 may control electronic components in another RF module to be changed to be driven in advance. In this regard, if it is determined that the quality of the received signal is degraded, the baseband processor 1400 operates the second transceiver circuit 1200b in the first communication system before the second transmission period, which is the transmission period, starts. can be controlled For example, if it is determined that the first antenna is in the grip state, the baseband processor 1400 controls the second transceiver circuit 1200b to operate in the first communication system before the second transmission period, which is the transmission period, starts. can

Accordingly, the present invention is different from the method of performing antenna switching through a switch between the transceiver circuit and the antenna when it is determined that the received signal quality is deteriorated or a specific antenna is in a grip state. In this regard, the present invention is characterized in that both the antenna and the transceiver circuit are changed when it is determined that the received signal quality is deteriorated or a specific antenna is in a grip state. To this end, while changing both the antenna and the transceiver circuit, the transceiver circuit is controlled to operate in a different communication system. Accordingly, there is no need to separately provide a switch configured to perform switching between different antennas and different transceiver circuits. Accordingly, in the present invention, there is no need to provide a separate switch, and thus performance degradation due to signal loss in the front end can be prevented.

On the other hand, if it is determined that the quality of the received signal is not deteriorated, the baseband processor 1400 may maintain the existing operation. In this regard, if it is determined that the quality of the received signal is not deteriorated, the baseband processor 1400 transmits the first signal through the first transceiver 1200a and the first antenna ANT1 in the second transmission period, which is the transmission period. can be controlled to transmit. For example, if it is determined that the first antenna is not in the grip state, the baseband processor 1400 transmits the first signal through the first transceiver 1200a and the first antenna ANT1 in the second transmission period, which is the transmission period. can be controlled to do so.

Meanwhile, as described above, in order to perform switching between the reception signal quality-based antenna and the transceiver circuit, the UE corresponding to the electronic device may maintain an EN-DC (EUTRAN NR Dual Connectivity) state. Accordingly, the baseband processor 1400 may maintain an EN-DC state connected to the first base station operating in the first communication system and connected to the second base station operating in the second communication system. Accordingly, the baseband processor 1400 may perform at least one of 4G UL MINO, 5G UL MINO, or 4G + 5G UL transmission through the first antenna ANT2 and the second antenna ANT2 .

Meanwhile, in relation to the above-described transmission signal control method, the first communication system and the second communication system may support time division duplex (TDD). To this end, the baseband processor 1400 may control to transmit the first transmission signal to the first base station in a time division multiplexing scheme and to receive the first received signal from the first base station. Also, the baseband processor 1400 may control to transmit the second transmission signal to the second base station in a time division multiplexing scheme and to receive the second received signal from the second base station.

In this regard, FIG. 8A shows antenna switching in a normal state and a hand grip state for each 4G/5G priority case. Meanwhile, FIG. 8B illustrates a comparison between a TDD system and an FDD system according to an embodiment.

Figure 8a (a) shows a 4G priority case (4G priority case). Referring to FIG. 8A (a), in a normal condition, the first antenna ANT1 disposed below the UE operates as a 4G antenna, and the second antenna ANT2 disposed above the UE operates as a 5G antenna. can do. Accordingly, the UE may maintain a dual connection (EN-DC) state in the NSA mode through the first antenna ANT1 and the second antenna ANT2. Alternatively, the UE may maintain a connection state with the 5G network through the second antenna ANT2 in the SA mode.

In a hand grip case, the first antenna ANT1 disposed under the UE may be converted into a 5G antenna. In this regard, referring to FIGS. 7A, 7B, and 8A (a), the first transceiver circuit 1200a connected to the first antenna ANT1 may be controlled to operate in a 5G band. However, when the UE operates in the 5G SA mode, the first antenna ANT1 disposed under the UE may be configured not to be used without being converted to a 5G antenna (Not used).

On the other hand, the second antenna ANT2 that is not in the hand grip state disposed over the UE may be converted to a 4G antenna. In this regard, the second transceiver circuit 1200b connected to the second antenna ANT2 may be controlled to operate in a 4G band. In addition, even when the UE operates in the 5G SA mode, the second antenna ANT2 may be switched to a 4G antenna. In this regard, the second transceiver circuit 1200b connected to the second antenna ANT2 may also be controlled to operate in the 4G band.

Therefore, in the UE operating in the NSA mode in the 4G priority case, the first antenna in which the hand grip is generated is switched to the 5G antenna, and the second antenna in which the hand grip is not generated can be switched to the 4G antenna. . In this case, the first transceiver circuit connected to the first antenna in which the hand grip is generated may operate in the 5G band, and the second transceiver circuit connected to the second antenna in which the hand grip is not generated may operate in the 4G band.

On the other hand, the UE operating in the SA mode in the 4G priority case may switch the second antenna for which the hand grip is not generated to the 4G antenna. In this case, the second transceiver circuit connected to the second antenna in which the hand grip is not generated may operate in the 4G band.

Figure 8a (b) shows a 5G priority case (5G priority case). Referring to FIG. 8A ( b ), in a normal condition, the first antenna ANT1 disposed below the UE operates as a 5G antenna, and the second antenna ANT2 disposed above the UE operates as a 4G antenna. can do. On the other hand, the second antenna ANT2 disposed above the UE in the 5G SA mode of the UE may be configured not to be used as a 4G antenna (Not used). Accordingly, the UE may maintain a dual connection (EN-DC) state in the NSA mode through the first antenna ANT1 and the second antenna ANT2. Alternatively, the UE may maintain a connection state with the 5G network through the second antenna ANT2 in the SA mode.

In a hand grip case, the first antenna ANT1 disposed under the UE may be converted to a 4G antenna. In this regard, referring to FIGS. 7A, 7B, and 8A (b), the first transceiver circuit 1200a connected to the first antenna ANT1 may be controlled to operate in a 4G band. On the other hand, when the UE operates in the SA mode and the first antenna ANT1 disposed under the UE is in a hand grip state, the first antenna ANT1 is switched to a 4G antenna and configured not to be used (Not used) there is.

On the other hand, the second antenna ANT2 that is not in a hand grip state disposed over the UE may be converted to a 5G antenna. In this regard, the second transceiver circuit 1200b connected to the second antenna ANT2 may be controlled to operate in the 5G band. On the other hand, when the UE operates in the 5G SA mode, the second antenna ANT2 may be switched to a 4G antenna and configured not to be used (Not used).

Therefore, in the UE operating in the NSA mode in the 5G priority case, the first antenna in which the hand grip is generated is switched to the 4G antenna, and the second antenna in which the hand grip is not generated can be switched to the 5G antenna. . In this case, the first transceiver circuit connected to the first antenna in which the hand grip is generated may operate in the 4G band, and the second transceiver circuit connected to the second antenna in which the hand grip is not generated may operate in the 5G band.

On the other hand, the UE operating in the SA mode in the 5G priority case may switch the second antenna for which the hand grip is not generated to the 5G antenna. In this case, the second transceiver circuit connected to the second antenna in which the hand grip is not generated may operate in the 5G band.

Meanwhile, referring to FIG. 8B( a ), the TDD system transmits and receives at a time ratio without dividing the frequency domain into Tx and Rx sections. In this regard, the TDD system has better frequency efficiency from the point of view of the user than the FDD system in a terminal in which reception through the downlink (DL) is heavily weighted. As shown in FIG. 8B( a ), it can be seen that the ratio occupied by the Rx region is higher than the ratio occupied by the Tx region.

Meanwhile, the FDD system may use a part of the entire frequency domain as the Tx frequency domain and use the remaining frequency domain as the Rx frequency domain. For example, an FDD system using Band 7 may use 2500 MHz to 2570 MHz as the Tx band. In addition, the FDD system using Band 7 may use 2620 MHz to 2690 MHz as the Rx band. On the other hand, the TDD system using Band 41 as shown in FIG. 8b(a) may use the entire band of 2496 MHz to 2690 MHz as the TX/RX band.

From the viewpoint of the time interval, the TDD system has a short and discontinuous Tx interval. Therefore, in the TDD system, the quality of the Tx signal is very important for call maintenance. Therefore, it can be said that the hand grip effect is higher in the TDD system having a short and discontinuous Tx section compared to the FDD system. In particular, when a technology for increasing transmission power, such as PC2 (HPUE), is applied, the TDD system has a higher hand grip effect than the FDD system.

Meanwhile, since the TDD system does not perform signal transmission in the Rx section, there is no power consumption in the Rx section, and power consumption occurs again in the Tx section. Therefore, the TDD system is advantageous in terms of heat generation and consumes less current than the FDD system. Accordingly, in the present invention, it is noted that an event in the Rx section in which signal transmission is not performed does not affect signal transmission. That is, whether a Tx Reset Event such as a hand grip occurs is detected in the RX section, and even when a Tx Reset Event occurs, the subsequent operation is the same as the basic operation. That is, regardless of whether a Tx Reset Event occurs or not, the Tx RF module that was turned off in the Rx section is changed to the on state in the subsequent Tx section.

Referring to FIG. 8b (b), the FDD system maintains continuous transmission/reception. If a discontinuous section exceeding a specific time section occurs in the Tx section, it is necessary to maintain the call by reconnecting the call. In the FDD system of FIG. 8B (b), the Tx band and the Rx band may be the Tx band and the Rx band divided within the same band. As an example, the band of the FDD system of FIG. 8B (b) may be divided into a Band 7 Tx band and a Band 7 Rx band. However, the band of the FDD system is not limited thereto. In this regard, when a Tx Reset Event occurs in the Tx band, the base station may perform an action for call connection again. In addition, the UE proceeds with reconnection for call connection again. Therefore, when a Tx Reset Event occurs in the FDD system, system issues for reconnection occur.

On the other hand, in the TDD system, the Tx RF module that was turned off in the Rx section is changed to the on state in the subsequent Tx section regardless of whether or not a Tx Reset Event occurs. Accordingly, in the TDD system, even when a Tx Reset Event occurs, system issues for reconnection do not occur. In this regard, referring to FIGS. 7 and 8B , when all 4G/5G communication systems operate as TDD systems (TDD+TDD), the Tx RF module is turned off during Rx operation and is changed to on state during Tx operation. do. Accordingly, even if the Tx path is changed in the TDD system, there is no need to reset the Tx chain and the power amplifier PA in the RFIC 1250 .

On the other hand, the electronic device performing the transmission signal control method according to the present invention may perform the transmission signal control method through a series of procedures. In this regard, FIG. 9A is a flowchart of a method for controlling a transmission signal according to an embodiment. Meanwhile, FIG. 9B is a flowchart of a method for controlling a transmission signal according to another embodiment. 9C is a flowchart of a method for controlling a transmission signal in a 5G SA mode according to another embodiment.

9A and 9B , the transmission signal control method may be performed when both the first communication system and the second communication system operate as TDD systems in the EN-DC state. That is, when both the 4G LTE communication system and the 5G communication system operate as a TDD system, the transmission signal control method may be performed. In addition, the transmission signal control method may be performed only when the Tx/Rx time timings of LTE and NR are synchronized while both the 4G LTE communication system and the 5G communication system (NR) operate as TDD systems.

Accordingly, in the case of LTE FDD/5G FDD, LTE FDD/5G TDD or LTE TDD/5G FDD, the transmission signal control algorithm according to the present invention may not be performed. However, the present invention is not limited thereto, and even in the case of LTE FDD/5G FDD, it may be performed through Rx slot monitoring for an arbitrary signal in an arbitrary time interval in which signal transmission is not performed. In this regard, a transmission resource may be allocated to a UE other than the corresponding UE in the FDD system. Therefore, it can be performed through Rx slot monitoring for an arbitrary signal in a section in which the corresponding UE does not transmit a signal. In this case, any signal that is the target of Rx slot monitoring may be a signal allocated to the corresponding UE. However, the arbitrary signal is not limited thereto and may be any control signal transmitted through the PDCCH.

Meanwhile, in the case of LTE FDD/5G TDD, it may be performed through Rx slot monitoring in an arbitrary time interval in which signal transmission is not performed. As described above, in the FDD system, a transmission resource may be allocated to a UE other than the corresponding UE. Therefore, it can be performed through Rx slot monitoring for an arbitrary signal in a section in which the corresponding UE does not transmit a signal. In this case, any signal that is the target of Rx slot monitoring may be a signal allocated to the corresponding UE. However, the arbitrary signal is not limited thereto and may be any control signal transmitted through the PDCCH. On the other hand, an arbitrary signal that is a target of Rx slot monitoring may be a 5G TDD signal. Accordingly, when the 5G reception signal quality is degraded, it is determined that the 4G signal characteristics are also degraded, so that the antenna and the transceiver circuit can be switched.

Meanwhile, even in the case of LTE TDD/5G FDD, signal transmission may be performed through Rx slot monitoring in an arbitrary time interval. In the case of such LTE TDD, antenna switching may be performed in the next transmission section through Rx slot monitoring. In this regard, in this regard, a transmission resource may be allocated to a UE other than the corresponding UE in the 5G FDD system. Accordingly, it may be performed through Rx slot monitoring for an arbitrary signal in a section in which the corresponding UE does not transmit a 5G signal. In this case, any signal that is the target of Rx slot monitoring may be a 5G signal allocated to the corresponding UE. However, the arbitrary signal is not limited thereto and may be any 5G control signal transmitted through the PDCCH.

In addition, when two or more antennas are provided, the 4G LTE signal may be transmitted through the second antenna ANT2 having good 4G reception quality without transmitting the 5G signal. On the other hand, in the method of switching the antenna and the transceiver circuit as described above, a higher priority is not assigned to the 4G LTE signal. For example, when a higher priority is assigned to the 5G signal in the SA structure, the method of switching the antenna and the transceiver circuit may be performed based on the 5G signal.

Meanwhile, in the present invention, when both LTE and 5G support TDD, a method for controlling a transmission signal, that is, a method for switching an antenna and a transceiver circuit will be described in detail. In this regard, FIG. 9A shows a flowchart of a received signal quality-based transmission signal control method. On the other hand, FIG. 9B shows a flowchart of a hand grip-based transmission signal control method. In addition, FIG. 9c shows a flowchart of a transmission signal control method in the 5G SA mode according to FIG.

Meanwhile, the transmission signal control method in FIGS. 9A to 9B may be performed by at least one processor. As an example, the transmission signal control method in FIGS. 9A to 9C may be performed by a baseband processor, that is, a modem. Meanwhile, FIG. 10A shows signaling between a modem, a network, and an RF module in relation to determination of received signal quality. Meanwhile, FIG. 10B shows signaling between a modem, a network, and a sensor in relation to determining whether to grip.

9A and 10A, the transmission signal control method includes a signal transmission control process (S100) in a first transmission section, a received signal quality determination process (S200), and a signal transmission control process (S300) in a second transmission section can be configured to On the other hand, the transmission signal control method includes a signal transmission control process in the first transmission section (S100), an Rx section entry determination process (S150), a received signal quality determination process (S200), and a signal transmission control process in the second transmission section (S300). It may be configured to include

9B and 10B, the transmission signal control method includes a signal transmission control process (S100) in a first transmission section, a grip determination process (S200b), and a signal transmission control process (S300) in a second transmission section can be configured. On the other hand, the transmission signal control method includes a signal transmission control process (S100), an Rx section entry determination process (S150), a grip status determination process (S200b), and a signal transmission control process (S300) in the second transmission section in the first transmission section. can be configured to include.

Meanwhile, referring to FIGS. 9C and 10B , the transmission signal control method includes a signal transmission control process (S100) in a first transmission section, a grip determination process (S200c), and a signal transmission control process (S300) in a second transmission section. can be configured to include. On the other hand, the transmission signal control method includes a signal transmission control process (S100) in the first transmission section, an Rx section entry determination process (S150c), a grip presence determination process (S200c), and a signal transmission control process (S300) in the second transmission section can be configured to include.

9A to 9C, in the signal transmission control process S100 in the first transmission section, the first signal of the first communication system is transmitted through the first transceiver circuit and the first antenna in the first transmission section. can be controlled On the other hand, in the Rx section entry determination process (S150, S150c), it is determined whether it is a reception section (eg, a first reception section) subsequent to the first transmission section, and control to turn off some electronic components inside the Tx RF module can In this regard, power consumption may be reduced by turning off the power amplifier PA when the reception period is entered.

Meanwhile, in the received signal quality determination process ( S200 ), it is possible to determine the quality of a received signal received through the first antenna and the first transceiver operating in the first communication system in the reception section. Accordingly, when it is determined that the quality of the received signal is deteriorated, in the signal transmission control process ( S300 ), the signal of the first communication system is transmitted through the second transceiver and the second antenna in the transmission section subsequent to the reception section. can be controlled That is, if it is determined that the quality of the received signal is deteriorated, it is possible to control to transmit the first signal through the second transceiver and the second antenna in the second transmission section.

In another embodiment, in the grip determination process (S200b), it may be determined whether the grip state for a specific antenna in the reception section. For example, it may be determined whether the grip state with respect to the first antenna or the second antenna in the reception section. Accordingly, when it is determined that the first antenna is in the grip state, in the signal transmission control process ( S300 ), the control is performed to transmit the signal of the first communication system through the second transceiver and the second antenna in the transmission section subsequent to the reception section can do. That is, when it is determined that the first antenna is in the grip state, it is possible to control to transmit the first signal through the second transceiver and the second antenna in the second transmission section.

Meanwhile, referring to FIG. 9A , the Tx on process ( S250 ) may be performed after the received signal quality determination process ( S200 ). The Tx on process ( S250 ) may be performed regardless of whether the received signal quality is degraded. Even when the received signal quality is maintained, an electronic component inside the Tx RF module associated with the first transceiver circuit may be controlled to be turned on through the Tx on process ( S250 - 1 ). On the other hand, when the quality of the received signal is deteriorated, an electronic component inside the Tx RF module associated with the second transceiver circuit may be controlled to be in an on state through the Tx on process ( S250 - 2 ).

For example, if it is determined that the quality of the received signal is deteriorated, a process (S250-2) of controlling the second transceiver circuit to operate in the first communication system before the start of the second transmission period, which is the transmission period, may be performed. can On the other hand, if it is determined that the quality of the received signal is not deteriorated, a process (S250-1) of controlling to transmit the first signal through the first transceiver and the first antenna in the second transmission period, which is the transmission period, will be performed. can

Also, referring to FIG. 9B , a Tx on process ( S250b ) may be performed after the received signal quality determination process ( S200 ). The Tx on process ( S250b ) may be performed regardless of whether the grip is in the grip state. Even when not in the grip state, it is possible to control the electronic component inside the Tx RF module associated with the first transceiver circuit to be in the on state through the Tx on process (S250b). Meanwhile, when it is determined that the grip state is in the grip state, an electronic component inside the Tx RF module associated with the second transceiver circuit may be controlled to be in the on state through the Tx on process ( S250b ).

For example, if it is determined that the grip state is, the LTE/NR path may be switched. Accordingly, the process of controlling the second transceiver circuit to operate in the second communication system (S250-2) may be performed before the second transmission period, which is the transmission period, starts. On the other hand, when it is determined that the grip state is not, a process of controlling to transmit the first signal through the first transceiver and the first antenna in the second transmission section, which is the transmission section, may be performed ( S250 - 1 ).

Meanwhile, referring to FIG. 9C , the Tx on process ( S250c ) may be performed after the received signal quality determination process ( S200 ). The Tx on process ( S250c ) may be performed regardless of whether the grip is in the grip state. Even when not in the grip state, it is possible to control the electronic component inside the Tx RF module associated with the first transceiver circuit to be in the on state through the Tx on process ( S250c ). Meanwhile, if it is determined that the grip state is in the grip state, an electronic component inside the Tx RF module associated with the second transceiver circuit may be controlled to be in the on state through the Tx on process ( S250c ).

For example, if it is determined that the grip state is in the grip state, the NR path may be switched. Accordingly, the process of controlling the second transceiver circuit to operate in the second communication system (S250-2) may be performed before the second transmission period, which is the transmission period, starts. On the other hand, when it is determined that the grip state is not, a process of controlling to transmit the first signal through the first transceiver and the first antenna in the second transmission section, which is the transmission section, may be performed ( S250 - 1 ). Therefore, in the 5G SA mode as shown in FIG. 9C, only the 5G NR path is maintained as a path connected to the antenna in which the hand grip is not generated. That is, in the 5G SA mode as shown in FIG. 9C , switching to the 4G LTE path is not separately performed according to the occurrence of the hand grip.

It has been described that the antenna and the transceiver circuit are switched by giving priority to the 4G signal transmission when the reception signal quality deteriorates or the hand grip occurs according to FIGS. 7A to 9C . However, the present invention is not limited thereto, and switching of the antenna and the transceiver circuit may be performed by giving priority to 5G signal transmission in an architecture such as an SA structure.

Meanwhile, referring to FIGS. 9A and 9B , in relation to the second reception section, the Rx section entry determination process ( S150 ) may be performed again. Accordingly, the following steps of the received signal quality determination process ( S200 ) or the grip status determination process ( S200b ) may be performed. In relation to the received signal quality determination process ( S200 ) or the grip status determination process ( S200b ), signaling may be performed between the modem and the network and the RF module or sensor.

As described above, FIG. 10A shows signaling between the modem and the network and the RF module in relation to the received signal quality determination. Meanwhile, FIG. 10B shows signaling between a modem, a network, and a sensor in relation to determining whether to grip.

10A and 10B , the modem may transmit (S10) a registration request message (Registration Request = UE Tx on) to a network (eg, a base station). In response, the modem may receive a registration accept message (Registration Accept = UE Rx on) from the network (S20). Meanwhile, the modem may transmit a service request message (Service Request = UE Tx on) to the network (S30). In response, the modem may receive a service accept message (Service Accept = UE Rx on) from the network (S40).

Accordingly, the modem may receive a DL transport message (DL Transport = UE Rx on) from the network and determine that it has entered the RX slot period (S150). Referring to FIG. 10A , the modem may acquire received signal quality (eg, RSSI, RSRP, or RSRQ, etc.) by interworking with the RF module ( S200 ). Accordingly, the modem may perform signal transmission preparation through the RF module determined according to the received signal quality ( S250 ). Accordingly, the modem may transmit a UL transport message (UL Transport = UE Tx) to the network in the transmission section (S300).

Referring to FIG. 10B , the modem may determine whether to grip the hand in conjunction with the grip sensor or the capacitor sensor ( S200b ). Accordingly, the modem may perform signal transmission preparation through the RF module determined according to the hand grip state ( S250b ). Accordingly, the modem may transmit a UL transport message (UL Transport = UE Tx) to the network in the transmission section (S300).

Accordingly, referring to FIGS. 7A to 10B , the baseband processor 1400 may receive signaling related to UE RX in downlink from a first base station (eg, eNB). As another example, the baseband processor 1400 may receive signaling associated with UE RX in downlink from a second base station (eg, gNB). In this regard, signaling associated with UE RX in the downlink may be a DL transport message (DL Transport = UE Rx on). Accordingly, it may be determined that the UE has entered the RX slot period by receiving signaling related to UE RX in the downlink (S150).

Accordingly, the baseband processor 1400 may determine whether to maintain or decrease the quality of the received signal received through the first antenna ( S250 ). Alternatively, the baseband processor 1400 may determine whether the grip is in a grip state using a capacitor sensor or a grip sensor for the first antenna ( S250b ).

Meanwhile, in relation to the signal transmission control method according to the present invention, an operation according to the definition of the Rx Slot Monitoring section for each TDD UL/DL configuration will be described as follows. In this regard, FIG. 11 shows a TDD UL/DL configuration according to an example. Meanwhile, in relation to the TDD UL/DL configuration, the 3GPP standard may define a case in which all time intervals, eg, all time slots in a subframe, consist of only UL or DL. However, in an actual commercial network, a time interval, for example, some time interval in a subframe may be a DL interval, and another time interval may be a UL interval. In addition, some time intervals in the subframe may further include a special subframe (SS) that can be used as a DL interval or a UL interval.

Referring to FIG. 11 , a DL interval may be arranged before all UL intervals, and it is possible to monitor whether the received signal quality deteriorates or grips in the DL interval before the start of the UL interval. Accordingly, it is possible to check the received signal quality or grip in the DL section and dynamically set the Tx path according to the status.

In this regard, with reference to FIGS. 5A, 8B and 11 , as described above, Rx slot monitoring for switching the antenna and the transceiver circuit is performed in the subframe period corresponding to the DL period. Therefore, when the TDD system is applied, there is an advantage in that there is no need to provide a separate control channel for switching the antenna and the transceiver circuit in the subframe. It is not efficient to provide a separate control channel for switching the antenna and the transceiver circuit in the slot for uRLLC data scheduled in mini-slot units as shown in FIG. 5A. Therefore, in the present invention, the Rx slot monitoring is performed in the DL subframe corresponding to the DL period without having a separate control channel for switching the antenna and the transceiver circuit in the slot.

In this regard, according to an embodiment, it is necessary to change both the active setting value of the 4G/5G data on the Tx Path and the RF analog circuit and the setting of the power amplifier (PA). Accordingly, even if a separate control channel for switching the antenna and the transceiver circuit is allocated to some symbols in the slot, it is impossible to smoothly perform the 4G/5G data conversion and settings described above during the corresponding partial symbol period. Accordingly, in the present invention, the difference is that monitoring is performed during the entire time period of the subframe "D=Downlink" period. In addition, the difference is that the control operation according to the setting change is performed during the entire time period of the subframe "S=Special" before the subframe "D=Downlink".

Specifically, referring to FIGS. 7A to 11 , the reception interval may be a downlink (DL) subframe (DL SF1, DL SF2) before a special subframe that may be set as a transmission interval or a reception interval. Accordingly, when it is determined that the quality of the received signal is deteriorated or the first antenna is in a grip state, the baseband processor 1400 may perform the following operation. That is, the baseband processor 1400 may control the second transceiver circuit 1200b to operate in the first communication system in a special subframe (SS).

As an embodiment, the baseband processor 1400 may perform the following operation when it is determined that the quality of the received signal is deteriorated or the first antenna is in a grip state. That is, the baseband processor 1400 controls the uplink frequency converter and the driving amplifier in the second transceiver circuit 1200b in the downlink (DL) subframes DL SF1 and DL SF2 before the Special Subframe (SS). can

As described above, the present invention is different from a method of performing antenna switching through a switch between the transceiver circuit and the antenna when it is determined that the received signal quality is deteriorated or a specific antenna is in a grip state. In this regard, the present invention is characterized in that both the antenna and the transceiver circuit are changed when it is determined that the received signal quality is deteriorated or a specific antenna is in a grip state. To this end, while changing both the antenna and the transceiver circuit, the transceiver circuit is controlled to operate in a different communication system. Accordingly, there is no need to separately provide a switch configured to perform switching between different antennas and different transceiver circuits. Accordingly, in the present invention, there is no need to provide a separate switch, and thus performance degradation due to signal loss in the front end can be prevented.

Accordingly, the configuration of the electronic device performing the above-described transmission signal control method will be described as follows. In this regard, FIG. 12 shows a detailed configuration of a transmitter of an electronic device that performs a method for controlling a transmission signal based on Rx slot monitoring according to an embodiment.

Referring to FIG. 12 , the transmitter of the electronic device is first and second power amplifiers PA1 operatively coupled to the first and second antennas ANT1 and ANT2 and the first and second antennas ANT1 and ANT2, respectively. , PA2). In this regard, other circuits including a filter may be provided between the first antenna ANT1 and the first power amplifier PA1 . In this case, the other circuits may be a switch or duplexer configured to separate the transmitter and the receiver. As an example, other circuits may be configured to mutually isolate a plurality of transmit paths or separate a plurality of receive paths from each other.

Here, a plurality of RF components disposed in a transmission path including the first power amplifier PA1 may be referred to as a first transceiver circuit 1200a. Also, a plurality of RF components disposed in a transmission path including the second power amplifier PA2 may be referred to as a second transceiver circuit 1200b.

Meanwhile, the RFIC 1250 may be configured to include a first Tx chain (Tx chain 0) and a second Tx chain (Tx chain 1). Meanwhile, the RFIC 1250 may be configured to further include a multiplexer (MUX) configured to control the first Tx chain (Tx chain 0) and the second Tx chain (Tx chain 1). Also, the RFIC 1250 may be configured to further include an RFIC controller 1251 configured to control electronic components in the first Tx chain (Tx chain 0) and the second Tx chain (Tx chain 1).

For example, the first transceiver circuit 1200a may be configured to include a first Tx chain (Tx chain 0) inside the RFIC 1250 . Accordingly, the first transceiver circuit 1200a may be configured to include the driving amplifier DA and the upconverter in the first Tx chain (Tx chain 0) in addition to the first power amplifier PA1. . Meanwhile, the second transceiver circuit 1200b may be configured to include a second Tx chain (Tx chain 1) inside the RFIC 1250 . Accordingly, the second transceiver circuit 1200b may be configured to include the driving amplifier DA and the upconverter in the second Tx chain (Tx chain 1) in addition to the second power amplifier PA2. .

In this case, the upconverters in the first and second Tx chains (Tx chain 0, Tx chain 1) may be implemented as quadrature upconverters to perform frequency conversion on I and Q channels. Meanwhile, the upconverter may include a local oscillator configured to generate an LO signal. In addition, the upconverter may further include a frequency mixer configured to generate an RF signal by synthesizing a baseband (BB) signal and an LO signal.

The detailed operation of each configuration in the electronic device having the configuration of the transmitter as shown in FIG. 12 is as follows.

1) The multiplexer (MUX) transmits the data transmitted from the modem 1400 to the corresponding Tx Chain using the BB signal. Therefore, 4G Data and 5G Data are transmitted to the corresponding Tx Chain through individual paths through the multiplexer (MUX).

2) Meanwhile, 4G data is a 4G data signal output through a multiplexer (MUX), which is a BB signal before being converted into RF.

3) 5G data is a 5G data signal output through a multiplexer (MUX), which is a BB signal before being converted into RF.

4) The RFIC controller 1251 is a controller configured to set the RFIC internal components. Meanwhile, the RFIC controller 1251 controls the VCO corresponding to the local oscillator inside the upconverter. Accordingly, the RFIC controller 1251 forms a signal according to a 4G or 5G waveform and controls the driving amplifier DA.

5) Voltage Controlled Oscillator (VCO) provides a reference frequency value of a frequency required for a specific signal and a gain for a specific signal. Here, the RF signal converted through the mixer to which the VCO output is applied as an input is input to the power amplifiers PA1 and PA2.

6) The first and second power amplifiers PA1 and PA2 amplify the input signal to a power level corresponding to the set 4G/5G parameter value and output an output signal.

7) The first and second antennas ANT1 and ANT2 are configured to transmit signals amplified and output from the first and second power amplifiers PA1 and PA2. Meanwhile, each of the first and second antennas ANT1 and ANT2 may be configured to operate in both the frequency band of the first communication system and the second communication system.

8) The capacitor sensors (Cap Senor1, 2) detect a change in microcurrent of the first and second antennas (ANT1, ANT2) when a hand grip occurs on or around the first and second antennas (ANT1, ANT2) configured to do Accordingly, the capacitor sensors Cap Senor1 and 2 are sensors configured to detect whether a hand grip has occurred in the corresponding antenna. In this regard, a minute current change may be detected through a change in the capacitor value. Accordingly, the capacitor sensors Cap Senor1 and 2 may be referred to as antenna sensors or antenna grip sensors.

Meanwhile, in the electronic device having the transmitter of FIG. 12 , an operation in the receiving section will be described as follows. In this regard, FIG. 13 is a conceptual diagram related to an operation in a reception section of the electronic device having the transmitter of FIG. 12 . Referring to FIG. 13 , since it is a reception (Rx) period, Tx signal transmission does not occur. In this regard, the transmission priority may be set to a higher priority of the 4G signal as described above. Alternatively, the transmission priority may be set to a higher priority of the 5G signal as described above. In this regard, in a data translation process such as 4G + 5G inter-CA (carrier aggregation), since the 5G data rate is higher than that of the 4G data, the 5G signal may be set to a higher priority.

Meanwhile, the data output state from the multiplexer (MUX) to the first and second Tx chains (Tx chain 0, 1) is No Data. In the reception (Rx) period, the first and second power amplifiers PA1 and PA2 are in an off state. However, it may be ready based on the Register Setting value previously transmitted from the modem 14000 . Accordingly, the first transceiver circuit 1200a including the first power amplifier PA1 in the reception (Rx) section may be set to a 4G configuration. On the other hand, the second transceiver circuit 1200b including the second power amplifier PA2 in the reception (Rx) section may be set to a 5G configuration. In this case, a decrease in received signal quality or a hand grip may be detected through the second capacitor sensor (Cap sensor2).

On the other hand, in the transmission (Tx) section after the receiving (Rx) section can be switched between the 4G communication system and the 5G communication system. As described above, the transmission priority may be set to a higher priority for the 5G signal. In this regard, in a data translation process such as 4G + 5G inter-CA (carrier aggregation), since the 5G data rate is higher than that of the 4G data, the 5G signal may be set to a higher priority. In this regard, FIG. 14A shows a detailed configuration of a transmitter in which switching between a 4G communication system and a 5G communication system is performed according to an embodiment. Meanwhile, FIG. 14B shows a detailed configuration of a transmitter in which switching between a 4G communication system and a 5G communication system is performed according to an embodiment.

Referring to FIG. 14A , the modem 1400 may detect whether a hand grip has occurred through a second capacitor sensor (Cap sensor2). When it is determined that the hand grip has occurred, the modem 1400 may control the first output of the multiplexer MUX to output 5G data. In this regard, the electronic device may further include a multiplexer (MUX) disposed between the baseband processor 1400 corresponding to the modem and the first transceiver circuit 1200a or the second transceiver circuit 1200b. .

The operation switching of the multiplexer (MUX) will be described with reference to FIGS. 12 and 14A as follows. Referring to FIG. 12 , the modem 1400 may control the first output of the multiplexer MUX to output 4G data in the first transmission section. Meanwhile, the modem 1400 may control the second output of the multiplexer MUX to output 5G data in the first transmission section.

On the other hand, referring to FIG. 14A , the modem 1400 may control the first output of the multiplexer MUX to output 5G data in the second transmission section. Meanwhile, the modem 1400 may control the second output of the multiplexer MUX to output 4G data in the second transmission section. However,

In this regard, the modem 1400 transmits 5G data and 4G data to the first and second Tx chains (Tx chain 0, 1) of the RFIC 1250 through a multiplexer (MUX), respectively, and transmits the previous transmission section and Conversely, you can pass data. While the multiplexer (MUX) transfers 5G data to the first Tx chain (Tx chain 0) of the RFIC 1250, a register may be set to have 5G parameters so that VCO1 operates as a 5G VCO. On the other hand, while the multiplexer (MUX) transfers 4G data to the second Tx chain (Tx chain 1) of the RFIC 1250, the register may be set so that VCO2 has 4G parameters to operate as a 4G VCO. However, in the state before the upconverter and the driving amplifier DA are driven, the output through the first Tx chain (Tx chain 0) and the second Tx chain (Tx chain 1) has no signal. is the state Accordingly, outputs through the first power amplifier PA1 and the second power amplifier PA2 are also in a no signal state.

On the other hand, referring to FIG. 14B , the modem 1400 controls the upconverter and the driving amplifier DA in the first Tx chain (Tx chain 0) in the RFIC 1250 to control the first Tx chain. (Tx chain 0) can be configured to output a 5G RF signal. On the other hand, the modem 1400 controls the upconverter and the drive amplifier DA in the second Tx chain (Tx chain 1) inside the RFIC 1250 to control the second Tx chain (Tx chain 1). This 4G RF signal can be output. In this regard, the modem 1400 may control the first and second Tx chains (Tx chain 0, 1) through the RFIC controller 1251 .

Meanwhile, the modem 1400 may set a register to have the 5G parameter so that the first power amplifier PA1 operates in the 5G band. Also, the modem 1400 may set a register to have a 4G parameter so that the second power amplifier PA2 operates in a 4G band.

In this regard, the modem 1400 may control the first power amplifier PA1 to output a 5G RF signal in a specific output power range in the 5G band. Also, the modem 1400 may control the second power amplifier PA2 to output a 4G RF signal in a specific output power range in the 4G band. In this regard, the modem 1400 may control the first and second power amplifiers PA1 and PA2 through the RFIC controller 1251 .

With reference to FIGS. 12 to 14 , an operation of each configuration according to a hand grip or a similar event in each configuration of the transmitter will be described in Tables 3 and 4. In this regard, Table 3 shows a case in which the hand grip occurs only in the first antenna ANT1 and a case in which the hand grip occurs in both the first and second antennas ANT1 and ANT2 .

On the other hand, if hand grip does not occur in both of the first and second antennas ANT1 and ANT2 or the received signal quality is maintained, the previous setting may be maintained. That is, the first Tx chain (Tx chain 0) and related electronic components are configured to process/amplify/output a 4G signal. On the other hand, the second Tx chain (Tx chain 1) and related electronic components are configured to process/amplify/output a 5G signal.

When hand grip occurs only in the second antenna ANT2 or the received signal quality is deteriorated, the first Tx chain (Tx chain 0) and related electronic components are configured to process/amplify/output a 4G signal. On the other hand, the second Tx chain (Tx chain 1) and related electronic components are configured to process/amplify/output a 5G signal.

Meanwhile, with reference to FIGS. 7A to 14 , a detailed configuration of an electronic device having a transmitter performing the event trigger-based transmission signal control method as described above and a corresponding receiver will be described as follows. In this regard, FIG. 15 shows a detailed configuration of an electronic device having a transmitter performing an event trigger-based transmission signal control method and a receiver corresponding thereto.

Referring to FIG. 15 , the electronic device may be configured to include a plurality of antennas ANT1 to ANT4 . In this regard, the first and second ANT1 and ANT2 may operate as a combined TX/RX antenna. The first and second ANT1 and ANT2 may be operatively coupled with an integrated front end module FEM. In this case, the integrated front-end module (FEM) may be functionally divided into a first FEM and a second FEM.

The first antenna ANT1 may operate to receive 4G/5G signals while operating to transmit 4G LTE Tx signals. Also, the second antenna ANT2 may operate to receive a 4G/5G signal while operating to transmit a 5G Tx signal.

In this regard, the electronic device including the plurality of antennas ANT1 to ANT4 may support 2 Tx UL MIMO or maintain the EN-DC state through the first and second antennas ANT1 and ANT2 . As shown in FIG. 15 , the EN-DC state may be maintained by transmitting a 4G LTE Tx signal through any one of the first and second (ANT1 and ANT2) and transmitting a 5G Tx signal through the other. On the other hand, 4G UL 2Tx MIMO may be performed by transmitting a 4G LTE Tx signal through both the first and second (ANT1 and ANT2). Alternatively, 5G UL 2Tx MIMO may be performed by transmitting a 5G Tx signal through both the first and second (ANT1 and ANT2).

Meanwhile, the third antenna ANT3 and the fourth antenna ANT4 may operate as reception antennas. Accordingly, the maximum DL 4RX MIMO may be performed through the first to fourth antennas ANT1 to ANT4. For example, 4G DL 4RX MIMO may be performed through all of the first to fourth antennas ANT1 to ANT4. Alternatively, 5G DL 4RX MIMO may be performed through all of the first to fourth antennas ANT1 to ANT4. On the other hand, 4G DL 2Tx MIMO and 5G DL 2RX MIMO may be performed through some of the first to fourth antennas ANT1 to ANT4.

Meanwhile, in relation to FIG. 15 , in the B41 (2496 to 2690 MHz) + n41 (2496 to 2690 MHz) band, Tx is Off in the receive (Rx) section and can operate only through the Rx Path. On the other hand, Rx is Off in the transmission (Tx) section and can only operate through the Tx Path. In this case, the Tx signal transmitted through the Tx path and the Rx signal received through the Rx path use the same antenna and the same filter. In this regard, in a communication system operating in TDD, the Tx operation and the Rx operation may be regarded as exclusive operations. On the other hand, the Rx signal flows into the 4G+5G integrated RF Front End 1200 and then branches to each Rx chain (RX0, RX1) in the RFIC 1250 .

Even if the Tx Path is changed, there is no change in the Rx Path and no additional path loss in the communication system. That is, the Rx Path uses the same antenna and the same filter as the Tx Path. To this end, all four Rx Paths operate in a time interval different from that of the Tx Path.

Meanwhile, in the structure of the transceiver unit as shown in FIG. 15 , there is no need to provide a path switching module including a switch or a duplexer between the first and second antennas ANT1 and ANT2 and the integrated front end module 1200 . Therefore, compared to a structure including a path switching module including a switch or a duplexer between the first and second antennas ANT1 and ANT2 and the integrated front-end module 1200, the transceiver structure of the present invention provides the antenna and the front-end performance. deterioration can be prevented. On the other hand, when the path switching module is provided with a path switching module including a switch or duplexer between the first and second antennas ANT1 and ANT2 and the integrated front-end module 1200, the switch or duplexer and the internal transmission line need. Accordingly, there is a problem in that RF signal loss occurs due to the switch or duplexer and an internal transmission line.

Accordingly, in order to solve this problem, the present invention receives the front-end module 1200 from the modem 1400 without a path switching module between the first and second antennas ANT1 and ANT2 and the integrated front-end module 1200 . /Control in the transmission section. Therefore, in the present invention, the 4G RF signal or the 5G RF signal can be optimally transmitted through the multiplexer (MUX) provided between the modem 1400 and the RFIC 1250 without loss of the RF signal.

In the above, a method for controlling a transmission signal in an electronic device having a plurality of transceivers and an antenna according to an embodiment has been described. A wireless communication system including an electronic device and a base station for performing a transmission signal control method in an electronic device having a plurality of transceivers and antennas will be described as follows. In this regard, FIG. 16 illustrates a block diagram of a wireless communication system to which the methods proposed in the present specification can be applied.

Referring to FIG. 13 , the wireless communication system includes a first communication device 910 and/or a second communication device 920 . 'A and/or B' may be interpreted as having the same meaning as 'including at least one of A or B'. The first communication device may represent the base station and the second communication device may represent the terminal (or the first communication device may represent the terminal and the second communication device may represent the base station).

Base station (BS) is a fixed station (fixed station), Node B, evolved-NodeB (eNB), gNB (Next Generation NodeB), BTS (base transceiver system), access point (AP: Access Point), gNB (general) NB), 5G system, network, AI system, RSU (road side unit), may be replaced by terms such as robot. In addition, the terminal (Terminal) may be fixed or have mobility, UE (User Equipment), MS (Mobile Station), UT (user terminal), MSS (Mobile Subscriber Station), SS (Subscriber Station), AMS (Advanced Mobile) Station), WT (Wireless terminal), MTC (Machine-Type Communication) device, M2M (Machine-to-Machine) device, D2D (Device-to-Device) device, vehicle, robot, AI module may be replaced by terms such as

The first communication device and the second communication device include a processor 911,921, a memory 914,924, one or more Tx/Rx radio frequency modules 915,925, Tx processors 912,922, Rx processors 913,923 , including

antennas

916 and 926 . The processor implements the functions, processes and/or methods salpinned above. More specifically, in DL (communication from a first communication device to a second communication device), an upper layer packet from the core network is provided to the processor 911 . The processor implements the functions of the L2 layer. In DL, the processor provides multiplexing between logical channels and transport channels, allocation of radio resources to the second communication device 920, and is responsible for signaling to the second communication device. A transmit (TX) processor 912 implements various signal processing functions for the L1 layer (ie, the physical layer). The signal processing function facilitates forward error correction (FEC) in the second communication device, and includes coding and interleaving. The coded and modulated symbols are divided into parallel streams, each stream mapped to OFDM subcarriers, multiplexed with a reference signal (RS) in the time and/or frequency domain, and using Inverse Fast Fourier Transform (IFFT) are combined together to create a physical channel carrying a stream of time domain OFDMA symbols. The OFDM stream is spatially precoded to generate multiple spatial streams. Each spatial stream may be provided to a different antenna 916 via a separate Tx/Rx module (or transceiver) 915 . Each Tx/Rx module may modulate an RF carrier with a respective spatial stream for transmission. In the second communication device, each Tx/Rx module (or transceiver) 925 receives a signal via each antenna 926 of each Tx/Rx module. Each Tx/Rx module recovers information modulated with an RF carrier and provides it to a receive (RX) processor 923 . The RX processor implements the various signal processing functions of layer 1. The RX processor may perform spatial processing on the information to recover any spatial streams destined for the second communication device. If multiple spatial streams are destined for the second communication device, they may be combined into a single OFDMA symbol stream by multiple RX processors. The RX processor uses a Fast Fourier Transform (FFT) to transform the OFDMA symbol stream from the time domain to the frequency domain. The frequency domain signal includes a separate OFDMA symbol stream for each subcarrier of the OFDM signal. The symbols and reference signal on each subcarrier are recovered and demodulated by determining the most probable signal placement points transmitted by the first communication device. These soft decisions may be based on channel estimate values. The soft decisions are decoded and deinterleaved to recover the data and control signal originally transmitted by the first communication device on the physical channel. Corresponding data and control signals are provided to the processor 921 .

The UL (second communication device to first communication device) is handled in the first communication device 910 in a manner similar to that described with respect to the receiver function in the second communication device 920 . Each Tx/Rx module 925 receives a signal via a respective antenna 926 . Each Tx/Rx module provides an RF carrier and information to the RX processor 923 . The processor 921 may be associated with a memory 924 that stores program code and data. Memory may be referred to as a computer-readable medium.
