In order to facilitate understanding of the technical solutions of the embodiments of the present application, the following description describes related technologies of the embodiments of the present application, and the following related technologies may be optionally combined with the technical solutions of the embodiments of the present application as alternatives, which all belong to the protection scope of the embodiments of the present application.

Signal modulation

In wireless communication, signal modulation is used for spectrum shifting of signals, that is, the input signal f1 and the modulated carrier f0 are subjected to nonlinear operation by a mixer to generate two signals and/or difference frequency signals as shown in fig. 2, and a required higher-order frequency signal f2 is selected from the two signals, that is, spectrum shifting from low frequency to high frequency is completed as shown in fig. 3. The frequency relationship is f2=f1+f0, where f1 is an input low frequency signal, f2 is an output high frequency signal, and f0 is a modulated carrier.

For wideband signals, its center frequency point is referred to as the position of a Direct Current (DC) carrier (which may also be referred to as the LO position, i.e., the local oscillator frequency position), as shown by f0 in fig. 2.

In practical implementation, as shown in fig. 4, a baseband integrated circuit (Baseband Integrated Circuit, BBIC) outputs a baseband signal, and inputs the baseband signal to a radio frequency transceiver, namely, a radio frequency integrated circuit (Radio Frequency Integrated Circuit, RFIC), and the RFIC modulates the baseband signal based on a direct current carrier, namely, f0, to obtain a radio frequency signal, and the radio frequency signal generated by the RFIC is further amplified by a Power Amplifier (PA) and output to an antenna, and the antenna radiates the amplified radio frequency signal into the air.

F0 is also referred to as the position of the direct current carrier, i.e. the frequency position of the local oscillator of the terminal device.

Reporting of the position of a DC carrier

As shown in fig. 4, the DC carrier of the terminal device may leak a portion of the signal during modulation of the signal to the transmit chain and be transmitted over the air via amplification of the PA. When the DC carrier is located in the channel 501 as shown in fig. 5, the channel 501 is an interfered channel, and the strength of the leaked DC carrier is stronger, for example, the signal-to-noise ratio' SINR) of the received signal is reduced when the leaked DC carrier is received by the base station. Therefore, the position of the DC carrier of the terminal device needs to be reported to the base station, and the base station removes the leakage signal according to the position of the specific DC carrier to improve the signal-to-noise ratio of the received signal.

In reporting the position of the DC carrier, reporting of different frequency bands is different:

for a Frequency Range (FR) 1 (Frequency band below 7.125 GHz), if the position of the DC carrier is located in the Frequency Range of the transmission signal, the terminal device reports the position of the DC carrier to the base station, and if the position of the DC carrier is not located in the Frequency Range of the transmission signal, the position of the DC carrier is not reported;

For FR2 (also called millimeter wave band, usually more than 24 GHz), if the DC carrier is located in the frequency range of the transmitted signal or in the frequency range of the received signal, the specific DC carrier position needs to be reported to the base station.

The reporting of the DC carrier position is to improve the received signal quality of the base station, so that a higher SINR can be obtained, and further, higher order modulation schemes such as 256QAM and 1024QAM can be used. Therefore, after the terminal device determines the own transmitting frequency band or receiving frequency band, the terminal device considers the improvement of the signal of the terminal device, and reports the position of the DC carrier to the base station after the position of the DC carrier is positioned in the own transmitting frequency band or receiving frequency band, and no matter the base station or the terminal device does not consider the influence on other UE.

In order to facilitate understanding of the technical solution of the embodiments of the present application, the technical solution of the present application is described in detail below through specific embodiments. The above related technologies may be optionally combined with the technical solutions of the embodiments of the present application, which all belong to the protection scope of the embodiments of the present application. Embodiments of the present application include at least some of the following.

Fig. 6 is a schematic diagram of a wireless communication method according to an embodiment of the present application, which is applied to a network device, and as shown in fig. 6, includes:

Optionally, when the network device determines that the modulation mode of the second terminal device is higher-order modulation, the network device sends reporting indication information to the first terminal device, so as to instruct the first terminal device to report the first position. At this time, the first terminal device reports the first position when determining that the target frequency range indicates the first terminal device to report the first position and determining that reporting indication information is received.

In the embodiment of the application, the network equipment configures the target frequency range for the first terminal equipment so as to instruct the first terminal equipment to report or not report the position of the direct current carrier, thereby realizing the effective report of the position of the direct current carrier, and reducing signaling overhead under the conditions of avoiding the reduction of the SINR of the received signal and ensuring the signal quality of the signal between the network equipment and the terminal equipment.

If the first terminal equipment determines that the direct current carrier of the first terminal equipment can generate interference on the signal quality of the second terminal equipment based on the relation between the target frequency range and the first position, the first position is determined to be reported. If the first terminal device determines that the direct current carrier of the first terminal device does not interfere with the signal quality of the second terminal device based on the relation between the target frequency range and the first position, the first position is determined not to be reported.

And if the first terminal equipment determines to report the first position, reporting the first position to the network equipment. If the first terminal device determines that the first position is not reported, the first position may not be reported, or the first position may be reported based on its implementation.

Fig. 8 is a schematic diagram of a wireless communication method according to an embodiment of the present application, which is applied to a communication system including a network device and a first terminal device, and as shown in fig. 8, includes:

Here, the description of the network device and the first terminal device in S801 refers to the description of the wireless communication method shown in fig. 6 and 7, and will not be repeated here.

Next, the frequency ranges in fig. 6 to 8 are explained.

In some embodiments, the target frequency range includes at least one of:

A first frequency range, where the first frequency range is used to instruct the first terminal device to report the first location when the first location is located within the first frequency range, or the first frequency range is used to instruct the first terminal device not to report the first location when the first location is located outside the first frequency range;

And the second frequency range is used for indicating the first terminal equipment to report the first position when the first position is located outside the second frequency range, or is used for indicating the first terminal equipment not to report the first position when the first position is located in the second frequency range.

It can be appreciated that if the first location is located within the first frequency range or outside the second frequency range, the first terminal device reports the first location. And if the first position is located outside the first frequency range or within the second frequency range, the first terminal equipment does not report the first position.

In the embodiment of the present application, the target frequency range may include one or both of the first frequency range and the second frequency range.

For the first frequency range, the first frequency range is a frequency range that the second terminal device may use. When the first position is located in the first frequency range, the direct current carrier of the first terminal device can generate interference on the signal quality of the second terminal device, and the first frequency range indicates the first terminal device to report the first position. When the first position is located outside the first frequency range, the direct current carrier of the first terminal device does not interfere with the signal quality of the second terminal device, and the first frequency range indicates that the first terminal device does not report the first position.

As shown in fig. 9, the first frequency range is a frequency range 91 between a frequency 901 and a frequency 902, and if the position of the dc carrier of the first terminal device is a frequency 903 and the frequency 903 is within the frequency range 91, the frequency range 91 indicates that the first terminal reports the frequency 903; if the position of the dc carrier of the first terminal device is the frequency 904, and the frequency 904 is located outside the frequency range 91, the frequency range 91 indicates that the first terminal does not report the frequency 904.

When the first position is located in the second frequency range, the direct current carrier of the first terminal device does not interfere with the signal quality of the second terminal device, and the second frequency range indicates the position where the first terminal device does not report the direct current carrier. When the first position is located outside the second frequency range, the direct current carrier of the first terminal device may interfere with the signal quality of the second terminal device, and the second frequency range indicates the position of the direct current carrier reported by the first terminal device.

As shown in fig. 9, the second frequency range is a frequency range 91 between the frequency 901 and the frequency 902, and if the position of the dc carrier of the first terminal device is the frequency 903 and the frequency 903 is within the frequency range 91, the frequency range 91 indicates that the first terminal does not report the frequency 903; if the position of the dc carrier of the first terminal device is frequency 904, where frequency 904 is located in frequency range 901, frequency range 91 indicates the first terminal to report frequency 904

In some embodiments, the first frequency range includes at least one of:

A first range, where the first range is a frequency range in a first bandwidth that is not overlapped with a second bandwidth, the first bandwidth is an uplink bandwidth used by the network device, and the second bandwidth is a bandwidth of the first terminal device;

Optionally, for FR1, the bandwidth of the first terminal device is a transmission bandwidth, i.e. an uplink bandwidth, and for FR2, the bandwidth of the first terminal device includes a transmission bandwidth and a reception bandwidth.

Alternatively, the uplink bandwidth used by the network device may be an uplink bandwidth supported by the network device, or a sum of uplink bandwidths of all cells under the network device, or a sum of uplink bandwidths of the first cell and uplink bandwidths of neighboring cells of the first cell.

Optionally, the uplink bandwidth of the first cell is an uplink bandwidth allocated by the network device to the first cell, or a bandwidth sum of uplink bandwidths used by all terminal devices under the first cell.

For the first range, the first range is determined based on an upstream bandwidth used by the network device and a bandwidth of the terminal device. The network device determines an upstream bandwidth used by itself, that is, a first bandwidth, and determines a bandwidth of the first terminal device, that is, a second bandwidth, and determines a bandwidth other than the second bandwidth in the first bandwidth, that is, a bandwidth of the first bandwidth that does not overlap with the second bandwidth, as a first range.

In an example, as shown in fig. 10, where the frequency range 1001 is a first bandwidth and the frequency range 1002 is a second bandwidth, the first range includes: a frequency range 1003 and a frequency range 1004.

The network device determines an uplink bandwidth of the first cell, that is, a third bandwidth, determines a second bandwidth, and determines a bandwidth other than the second bandwidth in the third bandwidth, that is, a bandwidth which is not overlapped with the second bandwidth in the third bandwidth, as a second range.

In an example, as shown in fig. 11, where the frequency range 1101 is a third bandwidth and the frequency range 1102 is a second bandwidth, the second range includes: a frequency range 1103 and a frequency range 1104.

And for the third range, the third range is the bandwidth of the first network accessed by the first terminal equipment.

Optionally, the first network is determined based on a network system currently used by the first terminal device. In an example, the first network is an NR network to which the first terminal device accesses. In an example, the first network is a mobile 4G network to which the first terminal device has access.

The bandwidth of the first network may be determined based on a first operator and a first network system, where the first operator is an operator to which the first terminal device belongs, and the first network system is a network system used by the first terminal device.

In the embodiment of the present application, the network device under the first network device may include a current network device, and may also include other network devices other than the current network device.

As shown in fig. 12, the first terminal device 1201 communicates with a network device 1202-1, where a network 1203 of the network device is a first network to which the first terminal device 1201 accesses, where the network devices under the network 1203 may further include the network device 1202-2.

In some embodiments, the second frequency range comprises:

and a fourth range, wherein the fourth range is the bandwidth of a second network, the second network is different from the first network, and the first network is the network accessed by the first terminal equipment.

The second network and the first network are different networks, wherein the second network may include: a network of the second operator and a network of the first operator other than the first network.

It will be appreciated that there is no overlap of the bandwidth of the first network and the bandwidth of the second network.

In an example, as shown in fig. 13, the bandwidth of the first network is bandwidth 1301 and the bandwidth of the second network includes bandwidth 1302. When the position of the dc carrier of the first terminal device is the frequency 1303, the bandwidth 1301 indicates the position of the dc carrier reported by the first terminal device. When the position of the dc carrier of the first terminal device is the frequency 1304, the bandwidth 1302 indicates that the first terminal device does not report the position of the dc carrier.

In some embodiments, the second network is different from the first network by at least one of the following parameters:

Mobile country code (Mobile Country Code, MCC), mobile network code (Mobile Network Code, MNC), network type.

In some embodiments, the first indication information includes at least one of:

first configuration information, wherein the first configuration information is used for indicating the offset of the target frequency range relative to a reference frequency point;

And the second configuration information is used for indicating a target frequency band, and the target frequency range is the frequency range of the target frequency band.

For the first configuration information, an offset between the target frequency range and the reference frequency point is indicated.

And under the condition that the first terminal equipment receives the offset, determining a target frequency range based on the offset and the reference frequency point.

In case the target frequency range comprises one continuous frequency range, the offset indicated by the first configuration information comprises an offset of the lowest frequency and the highest frequency of the target frequency range, respectively, with respect to the reference frequency point. In one example, as shown in fig. 14, the target frequency range is: f11 to f12, the offset indicated by the first configuration information includes: f11 is offset 1 with respect to the reference frequency point f10, and f12 is offset 2 with respect to the reference frequency point f 10.

In the case where the target frequency range includes a plurality of discontinuous frequency ranges, one frequency range corresponds to two offsets among the offsets indicated by the first configuration information. In one example, as shown in fig. 15, the target frequency range is: f11 to f12, f21 to f22, the offset indicated by the first configuration information includes: offset corresponding to f11 to f 12: offset 1 of f11 relative to reference frequency point f10, offset 2 of f12 relative to reference frequency point f10, and corresponding offsets of f21 to f 22: offset 3 of f21 relative to reference frequency point f10, and offset 4 of f22 relative to reference frequency point f 10.

In some embodiments, the first configuration information includes: a first value for determining the offset from a reference frequency interval.

Here, when the network device determines the first configuration information, the first value is determined based on the offset and the reference frequency interval, wherein the first configuration information may indicate a plurality of first values to determine a plurality of offsets from the reference frequency interval. After the first terminal equipment receives the first numerical value, determining an offset interval corresponding to the first numerical value based on the first numerical value and the reference frequency interval, and further enabling the first terminal equipment to determine a target frequency range based on the determined offset and the reference frequency point.

It can be understood that when there is a frequency smaller than the reference frequency point in the target frequency range, the first value corresponding to the frequency smaller than the reference frequency point is a negative number smaller than 0, which indicates that the frequency is smaller than the reference frequency point, and the offset corresponding to the frequency is negative; and for the frequency which is larger than the reference frequency point in the target frequency range, the first numerical value corresponding to the frequency which is larger than the reference frequency point is a positive number which is larger than 0, and the frequency is represented to be larger than the reference frequency point, and the offset corresponding to the frequency is positive.

In one example, the reference frequency interval is 10kHz, and the first configuration information indicates the following first values: 10 to 15. The offset is 100kHz to 150kHz and at this time, the target frequency range is a frequency range of 100kHz to 150kHz from the reference frequency point.

In one example, the reference frequency interval is 20kHz, and the first configuration information indicates the following first values: -5 to-1, 10 to 15. The offset is-100 kHz to-20 kHz and 200kHz to 300kHz, in which case the target frequency range includes: the frequency range from the reference frequency point is-100 kHz to-20 kHz and the frequency range from the reference frequency point is 200kHz to 300kHz.

Optionally, the method comprises the step of. The first value may be identified by a bit.

In some embodiments, the reference frequency interval is a subcarrier interval or a preset frequency interval.

Optionally, the subcarrier spacing is 15kHz.

The preset frequency interval is a frequency interval negotiated between the first terminal device and the network device for determining the offset in combination with the first value. Alternatively, the preset frequency interval is 5kHz, 10kHz, 15kHz, etc.

In some embodiments, the reference frequency point is one of:

Frequency points specified by a protocol;

A preset frequency point;

and the network equipment indicates the frequency point to the first terminal equipment.

The frequency point specified by the protocol is a set fixed frequency point, for example: 100MHz.

The preset frequency point is a frequency point negotiated by the first terminal device and the network device, and may be a specific frequency point, for example: 100MHz, 200MHz, may also be frequency points related to the configuration of the first terminal device, such as: the reference frequency point is the lowest frequency of the transmission bandwidth of the first terminal device.

And under the condition that the reference frequency point is the frequency point indicated by the network equipment to the first terminal equipment, the network equipment indicates the reference frequency point to the first network equipment, and the first terminal equipment determines the reference frequency point based on the indication of the network equipment.

For the second configuration information, the second configuration information indicates one frequency band, i.e., a target frequency band. And under the condition that the first network equipment receives the second configuration information, determining the frequency range of the target frequency band indicated by the second configuration information as a target frequency range.

Alternatively, the network device may determine the target frequency band based on one or more of the first range, the second range, the third range, and the fourth range, at which time the target frequency band may include one or more of the first range, the second range, the third range, and the fourth range.

In one example, the first range is 2570MHz to 2595MHz, and the target frequency band is: 2570MHz to 2620MHz, wherein 2570MHz to 2620MHz are frequency bands in which a first range of the plurality of frequency bands is located.

In one example, the third range is 2570MHz to 2595MHz, and the target frequency band is: 2550MHz to 2650MHz, wherein 2550MHz to 2650MHz are frequency bands in which a first range of the plurality of frequency bands is located.

In case the first indication information comprises the second configuration information, the first terminal device determines the target frequency band based on the second configuration information, but the first terminal device is not aware of the first range, the second range, the third range or the fourth range.

In some embodiments, the second configuration information includes: and the frequency spectrum segment corresponding to the second numerical value is the target frequency band.

Here, the second value is an identification of the target frequency band in the set plurality of spectrum segments, where different spectrum segments correspond to different values.

In an example, the second value is 38, the first frequency band is 38, and the target frequency range is the frequency range of 38: 2570MHz to 2620MHz.

In an example, the second value is 20, and the first frequency band is the 20 th frequency band in the divided 100 frequency bands, where the size of one frequency band can be customized.

In some embodiments, the division manner of the spectrum segment is a frequency band division manner specified by a protocol or a self-defined division manner based on a fixed frequency band interval.

The predefined frequency band division mode is a general frequency band division mode, for example: the frequency range of band 34 is 2120MHz to 2125MHz, the frequency range of band 38 is 2570MHz to 2620MHz, the frequency range of band 39 is 1880MHz to 1920MHz, and the frequency range of band 40 is 2300MHz to 2400MHz.

The self-defined frequency band division mode based on the fixed frequency interval is a self-defined frequency band division mode, and the different frequency bands have the same size and are fixed frequency intervals. In one example, the fixed frequency interval is 100MHz. In one example, the fixed frequency interval is 50MHz.

In some implementations, a second bandwidth is located within or outside the target frequency band, the second bandwidth being a bandwidth of the first terminal device.

In some embodiments, the first indication information includes third configuration information for indicating the third range or the fourth range, the third configuration information including at least one of:

A start frequency and a stop frequency;

Absolute radio frequency channel number (Absolute Radio Frequency Channel Number, ARFCN).

Here, the third configuration information is used to indicate a third range, i.e., a frequency range of the first network, or a fourth range, i.e., a frequency range of the second network. Both the third range and the fourth range may be indicated by the third configuration information. The third configuration information indicating the third range and the third configuration information indicating the fourth range are different in value.

In case the third configuration information comprises a start frequency and a stop highest frequency, the third range or the fifth range is directly indicated.

In the case of the ARFCN, the frequency range corresponding to the ARFCN is the third range or the fourth range.

It will be appreciated that ARFCN is a channel number defined in the range of from 0MHz to 3GHz in 5khz steps and from 3GHz to 24.25GHz in 15khz steps for channel division. In the case of channel number determination, then the corresponding frequency range is clear.

In some embodiments, the network device further performs the steps of:

the network equipment receives third information sent by the first terminal equipment; the third information is used for requesting the third configuration information.

At this time, the terminal device also performs the steps of: the first terminal device sends second indication information to the network device; the second indication information is used for requesting the third configuration information.

As shown in fig. 16, includes:

S1601, the first terminal device sends second instruction information to the network device.

And S1602, the network equipment sends third configuration information to the first terminal equipment.

In the embodiment of the application, the first terminal device can judge whether the first terminal device has the prior information in the fifth range or not, and send the second indication information to the network device under the condition that the first terminal device does not have the prior information in the fifth range so as to request the third configuration information indicating the fifth range.

In some embodiments, S601, the network device sends first indication information to a first terminal device, including: the network device sends the first indication information to the first terminal device through a radio resource control (Radio Resource Control, RRC) message.

Optionally, the RRC message includes: RRC reconfiguration message.

The wireless communication method provided by the embodiment of the application is further described below.

In the wireless communication method provided by the embodiment of the application, the base station informs the terminal that the DC position needs to be reported or not to be reported when the DC falls into which frequency range, such as the base station bandwidth and the like, and describes the indication mode of the frequency range which needs to be reported or not to be reported by the terminal equipment.

In reporting the position of the DC carrier in the related art, when the position of the DC carrier of the terminal device is located outside the carrier range of the terminal device, the reporting is not performed.

For UE1, the location of the DC carrier needs to be reported only when the location of the DC carrier is located in its transmit frequency range (FR 1) or transmit+receive frequency range (FR 2), but as shown in fig. 17, the location of the DC carrier is not reported to the network when the location of the DC carrier falls outside the frequency range of UE1 (UE 1 transmit frequency range for FR1 and UE1 transmit and receive frequency range for FR 2).

For one base station, as shown in fig. 18, multiple terminals are in transmitting states under one base station at the same time, and occupy different frequency domain resources. As shown in fig. 19, when the position of the DC carrier of UE1 falls within the transmission frequency range of UE2, it makes it difficult for the base station to demodulate the transmission signal of UE2, and thus the DC carrier of UE1 will cause uplink signal interference to UE2, reducing SINR. Under existing mechanisms, this interference cannot be eliminated because the base station does not know the location of the DC carrier of UE 1. Therefore, for the scenario that the DC carrier of the UE1 falls within the uplink transmission signal range of other UEs, it is necessary to consider how to perform the enhancement.

A straightforward way to process is to report the DC position also when the DC carrier position is outside the occupied spectrum, but this way has the following problems: the specific spectrum range is not clear, and the position of the DC carrier wave in a large range is reported by completely relying on the air interface signaling, so that not only is the air interface signaling greatly burdened, but also the air interface signaling is not necessary. Thus, a more flexible approach is for the base station to tell the terminal which frequency spectrum ranges the DC position needs to be reported or not to be reported when the DC falls into. And this spectral range may be determined by the base station.

According to the wireless communication method provided by the embodiment of the application, the base station configures the frequency spectrum range which needs to be reported or does not need to be reported to the terminal equipment, so that the UE can acquire the position of the DC carrier which needs to be reported or does not report, thereby avoiding that the position of the DC carrier of the UE1 falls into the emission frequency spectrum range of other UE2, and avoiding that the terminal equipment reports the position of the DC carrier which is not valuable when the DC of the UE1 falls into the frequency spectrum range of other base stations or operators.

In the following, in order to more clearly understand the wireless communication method provided by the embodiment of the present application, in fig. 20, an uplink bandwidth used by a base station, an uplink bandwidth of a cell, and a transmission bandwidth of a UE are described to illustrate a scenario of generating DC interference.

As shown in fig. 20, the NR uplink bandwidth (e.g., 400MHz bandwidth) used by the base station, i.e., active, is the range of uplink signals that the base station needs to receive in the current area, and these signals may be from multiple NR cells.

As shown in fig. 20, each NR cell has its supported uplink bandwidth (e.g., 100MHz bandwidth) that is used to serve multiple UEs.

As shown in fig. 20, each UE may occupy a portion of the cell bandwidth for transmission of uplink signals. Uplink interference will be caused when DC falls outside the UE transmit bandwidth and is contained within the current cell NR uplink bandwidth or within the NR bandwidth where the current base station is operating.

For the scenario shown in fig. 20 described above, where DC interference may occur, the base station may require the UE to report the location of its DC carrier. The manner in which the base station determines the interfered spectrum range may be as follows:

Mode 1 is determined based on the NR bandwidth at which the current base station is operating and the UE transmit bandwidth.

As shown in fig. 21, the NR bandwidth in which the base station operates is divided into: region 2101, region 2102, and region 2103 corresponding to the transmission bandwidth of the UE, region 2101 corresponding to a portion of the NR bandwidth of the base station operation that is lower than the transmission bandwidth of the UE, and region 2102 corresponding to a portion of the NR bandwidth of the base station operation that is higher than the transmission bandwidth of the UE. In the NR bandwidth where the current base station works, the UE1 occupies only part of the frequency spectrum of the area 2103 for transmission, and when the DC carriers fall into the illustrated areas 2101 and 2102, the DC carriers of the UE will cause interference to the UE uplink transmission in these areas, and at this time, the position of the DC carriers needs to be reported to the base station, so that the base station can improve the signal-to-noise ratio of the received signal by eliminating the DC carriers, and then the frequency ranges corresponding to the areas 2101 and 2102 are the frequency ranges that the DC needs to report.

Mode 2, based on the cell uplink frequency range and UE transmit bandwidth.

As shown in fig. 22, the cell uplink frequency range is divided into: region 2201, region 2202, and region 2203 corresponding to the transmission bandwidth of the UE, where the bandwidth corresponding to region 2201 is a portion of the uplink frequency range of the cell that is lower than the transmission bandwidth of the UE, and the bandwidth corresponding to region 2202 is a portion of the uplink frequency range of the cell that is higher than the transmission bandwidth of the UE. In the uplink frequency range (100 MHz is an example) of the cell, the UE1 occupies only a portion of the spectrum (such as uplink bwp=20mhz) of the region 2203 for transmission, and in the remaining frequency ranges (region 22011 and region 2202), the base station may schedule other UEs in the same cell to perform uplink transmission, so when the DC carrier of the UE1 falls into the illustrated region 2201 and region 2202, the DC carrier of the UE will cause interference to the uplink transmission of the UE in these regions, and at this time, the position of the DC carrier needs to be reported to the base station, so that the base station may improve the signal-to-noise ratio of the received signal by eliminating the DC carrier, and the frequency ranges corresponding to the region 2201 and the region 2202 are the frequency ranges that DC needs to be reported.

The manner in which the base station determines the interfered spectrum range further includes:

The mode 3, the position of the DC carrier of the terminal is only valuable and significant for the base station of the current network, because if the DC is located on the network of other operators or the frequency spectrum of the network of other network systems of the current operator, the DC of the terminal will not affect the current service base station, and the current base station cannot use the position information of the DC carrier received by the current base station. Therefore, as shown in fig. 23, when the DC carrier is located in the frequency range of the network to which the current terminal device accesses, reporting is performed, and when the DC carrier is located in the frequency range of the other network, reporting is not required. Usually, which network a cell belongs to is determined by MCC, MNC, network system.

In the embodiment of the application, the frequency range indication that the position of the DC carrier needs or does not need to be reported can be realized by the following modes:

Indication mode 1 indicates a frequency interval from a reference frequency point based on the reference frequency point

Based on the frequency range to be reported shown in fig. 21, as shown in fig. 24, the base station uses the reference frequency point F0 as a reference (F0 may be a certain frequency point in a default/predefined frequency band, such as the lowest starting frequency of the frequency band where the base station is located, or a certain frequency point indicated by the base station, etc.), the frequency interval of the area 2101 relative to the reference frequency point F0 may be offset from dis_1 to dis_2, and the offset of the area 2102 relative to the reference frequency point F0 may be offset from dis_3 to dis_4.

The indication of the frequency interval may be indicated by a step size, i.e. a reference frequency interval, which may be 15khz of the size of the subcarrier, or may be a contracted frequency interval, such as 5 khz. The frequency range needing to be reported or the frequency range not needing to be reported can be indicated by the step number between the base station indication and the reference frequency point F0.

Taking as an example dis_1 to dis_2 of the indication area 2101 shown in fig. 24 indicating that reporting is required based on the frequency interval, for the area 2101, dis_1 is 150khz; dis_2 is 300khz. Then the frequency range of field 2101 is a frequency interval of 10 to 20 steps when 15khz is used as the step size. The indication of the number of step sizes by the terminal can be indicated by bit.

Indication mode 2: indicating frequency bands

To simplify the indication of the DC reporting range, the indication may be based on a certain set spectral range, such as frequency band based indication. At this time, the base station indicates that the frequency spectrum range that the terminal needs to report or does not need to report is a certain frequency band, and as long as the DC of the terminal is located in the frequency band range, the terminal needs to report or does not report the DC. In the case that the frequency band indicated by the base station is the frequency range to be reported, as shown in fig. 25, the transmission bandwidth of the terminal may or may not be located in the frequency band, as shown in fig. 26.

Indication mode 3: indication auxiliary indication information

When a terminal accesses a cell, it knows which network the current cell belongs to or which network the current cell does not belong to.

For a network to which the terminal is connected, if the terminal has a priori information about the frequency spectrum of the network, reporting of the DC location may not be performed when the DC is located in a frequency spectrum not belonging to the network. Of course, when the DC is located in a spectrum not belonging to the network, whether to report the location of the DC carrier may be determined autonomously by the UE or may be indicated by the network. If the terminal does not have a priori information about the network spectrum, then there is a need for auxiliary indication information for the base station, which can specify the spectrum (e.g., LTE spectrum and/or NR spectrum) to which the network belongs. The specific indication may be, for example, a spectral range indication in MHz, or an absolute radio frequency channel number (Absolute Radio Frequency Channel Number, ARFCN) range. Wherein ARFCN is a channel number defined by NR in a range of 0MHz to 3GHz in 5khz steps and 3GHz to 24.25GHz in 15khz steps for uniform channel division. As long as the channel number is clear, the corresponding channel is clear and the frequency range used by the network is also determined.

In practical applications, besides determining whether to request the UE to report the position of the DC carrier based on the base station, the cell/carrier, and the operator spectrum range, the modulation mode adopted by the interfered UE to transmit the signal may be further considered, and only when the modulation mode is high-order modulation such as 64QAM, 256QAM, 1024QAM, or 2048QAM, the DC carrier of the UE1 will interfere the uplink signal of the UE2 to cause the problem of uplink demodulation of the base station, where the UE is required to report the DC position.

In the embodiment of the present application, the indication of whether the base station reports the DC carrier in the indicated frequency range may be an indication that requires UE to report, or may be an indication that does not require UE to report. The indication information reported by the base station to the DC may be sent to the terminal through an RRC message, such as an RRC reconfiguration message. And after receiving the frequency spectrum range information reported by the DC, the terminal can report the position of the DC carrier or not.
