Description

Communication method and communication device
The present application claims priority from chinese patent application filed on 30/04/2019, having application number 201910361020.4 and entitled "communication method and communication apparatus", the entire contents of which are incorporated herein by reference.
Technical Field
The present application relates to the field of communications, and more particularly, to a communication method and a communication apparatus.
Background
In order to overcome the high frequency path loss, the communication between the base station and the terminal needs to be aided by the antenna gain brought by the analog beam. Generally, analog beams are directional, and an analog beam shape (beam pattern) can be described by a main lobe direction and a beam width, and the narrower the beam width, the larger the antenna gain.
The base station and the terminal may transmit and receive beams toward a specific direction. For example, in the following communication, the base station transmits a beam in a specific direction, and the terminal receives a beam in a specific direction, and normal communication can be achieved only when the direction of the base station transmitting the beam and the direction of the terminal receiving the beam are aligned.
The selection of the reception beam and the transmission beam of the terminal needs to depend on the beam indication information provided by the base station. If the relative position between the base station and the terminal changes, the base station needs to indicate a new beam direction for the terminal.
An uplink Sounding Reference Signal (SRS) is transmitted by a terminal and received by a base station. SRS is typically used to estimate channel information for scheduling or beamforming.
The time frequency resource, the transmission beam, the transmission power and the like used by the terminal for transmitting the SRS are all allocated to the terminal by the base station. The time-frequency resource, the transmission beam, the transmission power and other related parameters used by the terminal to transmit the SRS are called SRS resource.
The base station may configure one or more SRS resource sets (SRS resource sets) for the terminal, where each SRS resource set has one or more SRS resources therein. Different sets of SRS resources assume different functions. The current communication protocol can support four functional sets of SRS resources: beam Management (beam Management), Codebook (Codebook), non-Codebook (non Codebook), and switched antenna (antenna Switching).
The base station configures each SRS resource set through signaling, and reconfigures through the signaling when the base station needs to inform the terminal to change the transmission beam in the non-periodic SRS resource.
For example, when the base station needs to notify the terminal to change the transmission beam in the aperiodic SRS resource, the base station sends a signaling to the terminal, where the signaling includes an SRS resource identifier and beam indication information. And after receiving the signaling, the terminal updates the transmission beam in the SRS resource.
As network demand continues to increase, the demands on latency and overhead in the network continue to increase. Therefore, how to reduce the update of the transmission beam in the aperiodic SRS resource to reduce the update delay and the signaling overhead is a technical problem to be solved.

The beam in the embodiments of the present application is a communication resource. The beam may be a wide beam, or a narrow beam, or other type of beam. The technique of forming the beam may be a beamforming technique or other technical means. The beamforming technique may be embodied as a digital beamforming technique, an analog beamforming technique, a hybrid digital/analog beamforming technique. Different beams may be considered different resources. The same information or different information may be transmitted through different beams. Alternatively, a plurality of beams having the same or similar communication characteristics may be regarded as one beam. One beam may include one or more antenna ports for transmitting data channels, control channels, sounding signals, and the like, for example, a transmission beam may refer to the distribution of signal strength formed in different spatial directions after signals are transmitted through the antenna, and a reception beam may refer to the distribution of signal strength in different spatial directions of wireless signals received from the antenna. It is to be understood that the one or more antenna ports forming one beam may also be seen as one set of antenna ports. The beam may also be embodied in a spatial filter (spatial filter) within the protocol.
Beam management resources refer to resources used for beam management, which in turn may be embodied as resources used for computing and measuring beam quality. The beam quality includes layer 1reference signal received power (L1-RSRP), layer 1reference signal received quality (L1-RSRQ), and the like. Specifically, the beam management resource may include a synchronization signal, a broadcast channel, a downlink channel measurement reference signal, a tracking signal, a downlink control channel demodulation reference signal, a downlink shared channel demodulation reference signal, an uplink sounding reference signal, an uplink random access signal, and the like.
The beam indication information is used to indicate the beams used for transmission, including transmit beams and/or receive beams. The beam indication information includes a beam number, a beam management resource number, an uplink signal resource number, a downlink signal resource number, an absolute index of a beam, a relative index of a beam, a logical index of a beam, an index of an antenna port corresponding to a beam, an antenna port group index corresponding to a beam, an index of a downlink signal corresponding to a beam, a time index of a downlink synchronization signal block corresponding to a beam, Beam Pair Link (BPL) information, a transmission parameter (Tx parameter) corresponding to a beam, a reception parameter (Rx parameter) corresponding to a beam, a transmission weight corresponding to a beam, a weight matrix corresponding to a beam, a weight vector corresponding to a beam, a reception weight corresponding to a beam, an index of a transmission weight corresponding to a beam, an index of a weight matrix corresponding to a beam, an index of a weight vector corresponding to a beam, an index of a reception weight corresponding to a beam, and a reception weight, The downlink signal includes at least one of a synchronization signal, a broadcast channel, a broadcast signal demodulation signal, a channel state information downlink signal (CSI-RS), a cell specific reference signal (CS-RS), a terminal specific reference signal (US-RS), a downlink control channel demodulation reference signal, a downlink data channel demodulation reference signal, and a downlink phase noise tracking signal. The uplink signal comprises any one of an uplink random access sequence, an uplink sounding reference signal, an uplink control channel demodulation reference signal, an uplink data channel demodulation reference signal and an uplink phase noise tracking signal. Optionally, the network device may further allocate a QCL identifier to a beam having a QCL relationship among beams associated with the frequency resource group. The beams may also be referred to as spatial transmit filters, the transmit beams may also be referred to as spatial transmit filters, and the receive beams may also be referred to as spatial receive filters. The beam indication information may also be embodied as a Transmission Configuration Index (TCI), and the TCI may include various parameters, such as a cell number, a bandwidth part number, a reference signal identifier, a synchronization signal block identifier, a QCL type, and the like.
Quasi-co-location (QCL): the co-location relationship is used to indicate that the plurality of resources have one or more same or similar communication characteristics, and for the plurality of resources having the co-location relationship, the same or similar communication configuration may be adopted. For example, if two antenna ports have a co-located relationship, the channel large scale characteristic of one port transmitting one symbol can be inferred from the channel large scale characteristic of the other port transmitting one symbol. The large scale features may include: delay spread, average delay, doppler spread, doppler shift, average gain, reception parameters, terminal device received beam number, transmit/receive channel correlation, received angle of arrival, spatial correlation of receiver antennas, angle of main arrival (AoA), average angle of arrival, AoA spread, and the like.
Spatial quasi-parity (spatial QCL): a spatial QCL can be considered as a type of QCL. Two angles can be understood for spatial: from the transmitting end or from the receiving end. From the transmitting end, if two antenna ports are spatially quasi co-located, it means that the corresponding beam directions of the two antenna ports are spatially identical, i.e., spatial filters are the same. From the receiving end, if it is said that the two antenna ports are spatially quasi-co-located, it means that the receiving end can receive the signals transmitted by the two antenna ports in the same beam direction, i.e. with respect to the receiving parameter QCL.
Beamforming techniques (beamforming) can achieve higher antenna array gain by spatially pointing to a particular direction. Analog beamforming, which may be implemented by radio frequency. For example, a radio frequency link (RF chain) adjusts the phase through a phase shifter to control the change in the direction of the analog beam. Thus, an RF chain can only fire one analog beam at a time.
Spatial relationship (spatial relationship): also known as uplink TCI (UL TCI). The spatial relationship may be used to determine a transmit beam for the uplink signal. The spatial relationship may be determined by beam training. The reference signal used for beam training may be, for example, an uplink reference signal, such as SRS, or a downlink reference signal, such as SSB or CSI-RS.
During communication, the terminal device may determine a transmit beam based on a spatial relationship indicated by the network device, and the network device may determine a receive beam based on the same spatial relationship.
The spatial relationship indication may include a cell identifier and a reference signal identifier, where the cell identifier may refer to a physical cell and/or a serving cell, and the reference signal identifier may be an identifier of an uplink reference signal, or may be an identifier of a downlink SSB or a downlink reference signal. When the reference signal in the spatial relationship indication is the SRS, the terminal needs to transmit a target signal or a channel using a transmission beam for transmitting the SRS. When the reference signal in the spatial relationship indication is an SSB or CSI-RS, the terminal needs to transmit the target signal or channel using the transmission beam corresponding to the reception beam receiving the SSB/CSI-RS.
Optionally, a bandwidth part (BWP) identifier may also be included in one spatial relationship indication.
Alternatively, the spatial relationship of the SRS may be configured by a single resource, i.e., each SRS resource is configured by a spatial relationship separately.
The technical solution in the present application will be described below with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of an application scenario to which the method of the embodiment of the present application may be applied. It should be understood that the method of the embodiments of the present application may include more or less apparatuses or devices in application scenarios, or may include devices or apparatuses with similar functions.
During communication between the base station 110 and the terminal 120, the terminal 120 transmits a signal in a specific direction, and the base station 110 receives the signal in the specific direction.
The resources used by the terminal 120 to transmit signals may be referred to as signal resources. The signal resources may include time domain resources, frequency domain resources, transmission beams, transmission power, and the like. In the embodiment of the present application, a transmission beam included in a signal resource is simply referred to as a transmission beam of the signal resource, and a transmission power included in the signal resource is simply referred to as a transmission power of the signal resource.
The transmit beams used by the terminal 120 are typically configured by the base station 110. For example, the terminal 120 receives the configuration information from the base station 110, and determines the transmission beam in the signal resource as the transmission beam indicated by the configuration information, or transmits the signal corresponding to the signal resource by using the transmission beam indicated by the configuration information.
For example, the base station may configure the spatial relationship of each SRS resource through RRC. The terminal may determine a transmit beam based on the spatial relationship.
In many cases, for example, the relative position between the base station 110 and the terminal 120 changes, the base station 110 needs to indicate a new transmission beam for the terminal 120, i.e. to reconfigure or update the transmission beam in the signal resource.
Fig. 2 is an exemplary flow chart of a communication method in one embodiment of the present application. It should be understood that fig. 2 shows steps or operations of the method, but these steps or operations are only examples, and the technical solution proposed by the present application can also perform other operations or variations of the respective operations in fig. 2.
S210, the base station transmits first indication information, where the first indication information is used to indicate that a transmission beam of the first signal resource is configured as a first transmission beam. Accordingly, the terminal receives the first indication information.
The first indication information may be carried in an RRC signaling or a Media Access Control (MAC) -Control Element (CE) signaling. Of course, the first indication information may also be carried in other signaling, and this is not limited in this embodiment of the application.
The first indication information is carried in the MAC-CE signaling, and compared with the first indication information carried in the RRC signaling, the time delay and the signaling overhead can be reduced.
The first signal resource may be a non-periodic SRS resource, a periodic SRS resource, or a Physical Uplink Control Channel (PUCCH) resource. Of course, other resources may be available, and the embodiment of the present application is not limited to this.
The first indication information may include resource identification information of the first signal resource and beam indication information of the first transmission beam.
Or, the first indication information may include resource identification information and spatial relationship indication information of the first signal resource, and the first transmission beam may be determined according to the spatial relationship indication information.
Or, the first indication information may include resource identification information of the first signal resource, beam indication information of the first transmission beam, and function indication information, where the function indication information is used to indicate a function (use) of the first set of signal resources. One example is shown in fig. 14, and another example is shown in fig. 15.
Or the first indication information may include resource identification information of the first signal resource, beam indication information of the first transmission beam, and set identification information of the first set of signal resources. An example is shown in fig. 16.
It should be understood that the configuration in this embodiment may be that the base station configures the first signal resource for the first time (i.e., initializes the first signal resource), or may be that the base station updates the first signal resource.
S220, the terminal configures, according to the first indication information, transmission beams of multiple signal resources in a first signal resource set to which the first signal resource belongs as a first transmission beam.
The first set of signal resources may be aperiodic SRS resources, periodic SRS resources, or PUCCH resources.
Of course other sets of signal resources are possible.
The plurality of signal resources may be all signal resources in the first set of signal resources, or may be a part of the first set of signal resources including the first signal resource.
The plurality of signal resources may be a set of signal resources in the first set of signal resources, or the plurality of signal resources may be a set of signal resources. The division of the resource group can be configured by the base station, and can also be predefined by the protocol.
In this step, although the first indication information indicates that the transmission beam of the first signal resource is configured as the first transmission beam, the terminal may determine the transmission beams of the plurality of signal resources in the first signal resource set to which the first signal resource belongs as the first transmission beam. Compared with the configuration of only the first signal resource according to the first indication information, the other signal resources in the first signal resource set may not need to be reconfigured, so that signaling overhead may be saved, and the updated transmission beam may be used to transmit signals more quickly, thereby reducing transmission delay of other signals in the first signal resource set.
S230, the terminal transmits signals using the plurality of signal resources, wherein a transmission beam of the plurality of signal resources is the first transmission beam.
That is, the terminal may transmit a signal using a signal resource of the plurality of signal resources, and the transmission beam used for transmitting the signal is the first transmission beam because the transmission beam of the plurality of signal resources is the first transmission beam.
In general, the terminal transmits signals using the plurality of signal resources, and the transmission beam of the plurality of signal resources is the first transmission beam, which may also be understood as transmitting the plurality of signal resources using the first transmission beam.
In this embodiment of the application, optionally, the first set of signal resources may be a pre-designated set of signal resources. In this case, after receiving the first indication information from the base station, the terminal may determine a signal resource set (i.e., a first signal resource set) to which the first signal resource belongs, and determine whether the first signal resource set is a pre-specified signal resource set. If so, the terminal may determine a transmission beam of all or a portion of the signal resources in the first set of signal resources as the first transmission beam.
Alternatively, the function of the first set of signal resources may be pre-specified. For example, it is possible to configure on the terminal: when the first signal resource is an SRS resource, if the function of the first signal resource set is a pre-specified function, the terminal may determine a transmission beam in all or a part of the signal resources in the first signal resource set as a first transmission beam. In this way, after the terminal receives the first indication information and determines that the set of signal resources to which the first signal resource belongs is the first set of signal resources, it may determine whether it is necessary to determine the transmission beams of the plurality of signal resources in the first set of signal resources as the first transmission beam according to "usage" of the first set of signal resources, that is, whether the terminal may transmit a signal using the first transmission beam when transmitting a signal using any signal resource in the plurality of signal resources.
For another example, the function of the first set of signal resources may be a terminal-specific (UE-specific) PUCCH or a common (common) PUCCH. For example, when the first set of signal resources functions as a UE-specific PUCCH, the first indication information is used to indicate that a transmission beam of one UE-specific PUCCH is configured as a first beam; and according to the first indication information, the terminal determines all the transmission beams of the UE-specific PUCCH as a first beam. For example, when the function of the first signal resource set is common PUCCH, the first indication information is used to indicate that a transmission beam of one common PUCCH is configured as the first beam; according to the first indication information, the terminal determines all common PUCCH transmission beams as a first beam.
In this embodiment, optionally, the function corresponding to the first signal resource set may include switching antennas. That is to say, after the terminal receives the first indication information and determines that the signal resource set to which the first signal resource belongs is the first signal resource set, when determining that the first signal resource belongs to the signal resource set corresponding to the function of switching the antenna for the switching antenna according to "use" of the first signal resource set, the terminal may also determine the transmission beam of the other signal resources in the signal resource set as the first transmission beam; otherwise the terminal may determine only the transmission beam of the first signal resource as the first transmission beam. Therefore, the terminal can be ensured to correctly realize the function of antenna switching, because all signal resources in the first signal resource set corresponding to the function of antenna switching need to be configured into the same transmission beam, and all signal resources in the first signal resource set are determined as the first transmission beam according to the first indication information, which just can meet the requirement.
The first set of signal resources may also be other functions, such as a terminal transmit beam scanning function, i.e., a U3 function.
In the prior art, when the first signal resource is an SRS resource, an implementation manner of the terminal calculating the transmission power of the first signal resource includes the following steps: the terminal calculates the downlink path loss of the reference signal configured for the first signal resource by the base station through the RRC signaling, and calculates the transmission power of the first signal resource according to the following formula:
for example, when the first signal is an SRS, the transmission power may be calculated according to the following formula:
Figure BDA0002224077900000131
wherein b is BWP ID, f is carrier frequency (carrier) ID, c is cell ID, i is SRS transmission opportunityIdentification (SRS Transmission localization), PCMAX,f,c(i) For maximum output power of the terminal, PO_SRS,b,f,c(qs) Is a reference power p0, qsIdentifying for SRS resource set (SRS resource set), MSRS,b,f,c(i) Is SRS Bandwidth, αSRS,b,f,c(qs) Is a path loss compensation parameter, PLb,f,c(qd) Is a path loss estimate, qdIs a RRC configured path loss estimation reference signal, hb,f,c(i, l) is the power adjustment status of the current data channel, PSRS,b,f,c(i,qsL) is the calculated transmission power, and l is the identity of the SRS power control adjustment state.
In this embodiment of the application, optionally, when the reference signal of the first transmission beam is a downlink signal, the method may further include: the terminal calculates the downlink path loss according to the reference signal of the first transmission wave beam; and calculating the sending power of the first signal resource according to the downlink path loss.
For example, when the reference signal in the spatial relationship indication is a downlink signal, the terminal may calculate a downlink path loss according to the reference signal in the spatial relationship, and calculate the transmission power of the first signal resource according to the downlink path loss.
The terminal calculates downlink path loss according to the reference signal of the first transmission beam, and calculates the transmission power of the first signal resource according to the downlink path loss, which can refer to the prior art, but only replace the reference signal configured by the base station with the reference signal of the first transmission beam.
Or, the terminal adjusts the transmission power of the first signal resource according to a difference between the reception power of the reference signal of the first transmission beam and the reception power of the RRC-configured path loss estimation reference signal, for example, the reception power of the reference signal of the first transmission beam is 3dB higher than the reception power of the RRC-configured path loss estimation reference signal, so the transmission power of the first signal resource may be reduced by 3 dB. Optionally, the terminal may further adjust the transmission power of the first signal resource according to a difference between the transmission power of the reference signal of the first transmission beam and the transmission power of the RRC-configured path loss estimation reference signal.
This way, the signaling overhead of the reference signal configured by the base station for calculating the downlink path loss can be saved, and the time delay can be saved.
Optionally, when the reference signal of the first transmission beam is an uplink signal, the terminal transmits the first signal resource according to the transmission power for transmitting the uplink signal. The transmission power of the uplink signal may be the transmission power at which the terminal has transmitted the uplink signal last time, or may be the transmission power at which the uplink signal is initially configured.
Further, the method may further include the terminal determining the transmission power control parameters such as the reference power P0, the path loss compensation parameter alpha, and the power adjustment state according to the reference signal of the first transmission beam.
Optionally, the terminal determines the transmission power of the first signal resource according to the first transmission beam indication of the first signal resource, and further includes that the terminal adds a reference signal of the first transmission beam indicated by the MAC-CE signaling to the RRC-configured path loss estimation reference signal list.
Further, the method may further include: determining a transmit power of the plurality of signal resources in a first set of signal resources as the transmit power of a first transmit beam. That is, when the terminal transmits a signal using any of the plurality of signal resources, the terminal may transmit the signal using the transmission power of the first signal resource.
The terminal determines the transmission power of the plurality of signal resources in the first signal resource set as the transmission power of the first signal resource, so that the communication delay and the signaling overhead can be further saved.
In this embodiment of the application, optionally, before the terminal determines, according to the first indication information, beam transmission of multiple signal resources in the first set of signal resources as the first transmission beam, the method may further include: the base station transmits second indication information, wherein the second indication information is used for indicating that the transmission beam of the signal resource in the signal resource set to which the first signal resource belongs is configured to be the transmission beam indicated by the first indication information; accordingly, the terminal receives the second indication information.
That is, the base station explicitly indicates, through the second indication information, that the terminal may configure a transmission beam in other signal resources in the first set of signal resources to which the first signal resource belongs as the first transmission beam.
The second indication information and the first indication information may be carried in the same type of instruction or different types of instructions.
In the case that the second indication information is carried in the same type of instruction as the first indication information, further, the second indication information and the first indication information may also be carried in the same instruction. For example, the second indication information and the first indication information are both carried in the same MAC-CE signaling.
Under the condition that the second indication information and the first indication information are carried in different types of instructions or carried in the same type but not the same instruction, the sequence of the base station for sending the first indication information and the second indication information is not limited, and the sequence of the terminal for receiving the first indication information and the second indication information is not limited.
In the following, taking the first indication information carried in the MAC-CE signaling, where the first signal resource is an aperiodic SRS resource, and the first signal resource set is an SRS resource set corresponding to the antenna switching function as an example, the communication method according to the embodiment of the present application is further described with reference to fig. 3.
S310, the base station configures an aperiodic SRS resource set through RRC signaling. The terminal receives the RRC signaling, interprets the RRC signaling, and configures an aperiodic SRS resource set according to the RRC signaling, wherein the function of configuring the aperiodic SRS resource set is included.
This step can refer to the related implementation in 3GPP R15, and is not described herein again.
S320, the base station sends the beam indication updating information of the aperiodic SRS resource through MAC-CE signaling. And the terminal receives and interprets the MAC-CE so as to acquire the SRS resource needing to be updated and the transmission beam. The beam indication update information is the first indication information.
The MAC-CE signaling comprises SRS resource identification and transmission beam indication information.
S330, the terminal determines the transmission beam of the SRS resource according to the function of the SRS resource set configured in S310 and the transmission beam indicated by the MAC-CE signaling in S320.
For example, the terminal searches an SRS resource set identifier through the SRS resource identifier to determine an SRS resource set to which the SRS resource belongs; the terminal confirms the function of the SRS resource set to which the SRS resource belongs through the user; if the "use" of the SRS resource set is "antenna switch", the terminal updates the transmission beams of all SRS resources in the SRS resource set to the transmission beams indicated in S320; if the "use" of the SRS resource set is "beam management", "codebook", or "notcodeebook", the terminal updates the transmission beam of the SRS resource only using the transmission beam indicated in S320.
S340, the terminal determines the transmission power of the SRS resource according to the function of the SRS resource set configured in S310 and the transmission beam indicated by the MAC-CE signaling in S320.
For example, if the reference signal included in the transmission beam indication is a downlink signal, such as an SSB or a CSI-RS, the terminal may estimate the downlink path loss through the SSB or the CSI-RS, and further calculate the uplink transmission power. The method for calculating the transmission power may refer to the SRS transmission power calculation method in 3GPP R15.
In addition, if the "usage" of the SRS resource set is "antenna switch", the terminal updates the transmission power of all SRS resources in the SRS resource set to the transmission power calculated in this step. If the "usage" of the SRS resource set is "beam management", "codebook", or "nocodewood", the terminal updates the transmission power of the SRS resource only with the transmission power calculated in the above step.
S350, the terminal transmits the signal using the SRS resource in the SRS resource set, the transmission beam in the SRS resource is updated to the transmission beam indicated in S320 in S330, and the transmission power in the SRS resource is updated to the transmission power calculated in S340.
That is, when transmitting signals using the SRS resources in the SRS resource set, the transmission beam used is the transmission beam indicated in S320, and the transmission power used is the transmission power calculated in S340.
It should be understood that in the embodiment shown in fig. 3, S340 may not be included, or S330 and S340 may not have a chronological order.
Fig. 4 is an exemplary flow chart of a communication method in one embodiment of the present application. It should be understood that fig. 4 shows steps or operations of the method, but these steps or operations are only examples, and the technical solution proposed by the present application can also perform other operations or variations of the respective operations in fig. 4.
S410, the base station sends first indication information, and the first indication information is used for indicating that the sending beam of the signal resource corresponding to the first identifier is configured to be a first sending beam. Accordingly, the terminal receives the first indication information.
This step may refer to S210, except that the first indication information in S210 indicates that the transmission beam of the first signal resource is configured as the first transmission beam, and the first indication information in S410 indicates that the transmission beam of the signal resource corresponding to the first identifier is configured as the first transmission beam. The first identifier may be an identifier of one signal resource, or an identifier of one signal resource set, or may be an identifier of a group of signal resources, and accordingly, a signal resource corresponding to the first identifier may be one signal resource, or all signal resources in one signal resource set, or all signal resources in a group of signal resources.
S420, the base station sends second indication information, where the second indication information is used to indicate that a transmission beam of a signal resource in the first signal resource set corresponding to the first identifier is configured as the first transmission beam. Accordingly, the terminal receives the second indication information.
Or, it can be said, the second indication information is used to indicate that the first identifier is a signal resource set identifier.
Optionally, the second indication information may also indicate that the transmission beam of the signal resource identified by the first identifier is configured as the first transmission beam, that is, the second indication information may indicate that the first identifier is a signal resource identifier. When the second indication information indicates that the first identifier is a signal resource identifier, the specific implementation manner of the embodiment of the present application may refer to the communication method in fig. 2.
For example, the second indication information may include 1 bit, and when the value of the bit is "1", the display indicates that the first identifier in the first indication information is the resource set identifier, and when the value of the bit is "0", the display indicates that the first identifier in the first indication information is the resource identifier.
In general, the base station may transmit a transmission beam configuration of a signal resource set level (per resource set level) when the first signal resource set is configured to a specific function. For example, when the first signal resource set is antenna switching, the base station may send the second indication information to indicate that the first identifier in the first indication information is a resource set identifier, so as to indicate the terminal to implement transmission beam configuration at the signal resource set level.
The base station may transmit a transmit beam configuration of a signal resource level (per resource) when the first set of signal resources is configured for other specific functions. For example, when the first set of signal resources is a function other than antenna switching, the base station may transmit the second indication information indicating that the first identifier in the first indication information is a signal resource identifier to indicate that the terminal implements the transmission beam configuration at the signal resource level.
Accordingly, the terminal may expect different levels of transmission beam configuration signaling according to the function of the signal resource set. For example, when the first set of signal resources is configured for a particular function (e.g., antenna switching), the terminal device expects the network device to transmit a transmit beam configuration at the signal resource set level; when the first set of signal resources is configured to another specific function (e.g., a function other than antenna switching), the terminal device expects the network device to transmit a transmit beam configuration at the signal resource level.
The second indication information and the first indication information may be carried in the same type of instruction or different types of instructions.
In the case that the second indication information is carried in the same type of instruction as the first indication information, further, the second indication information and the first indication information may also be carried in the same instruction. For example, the second indication information and the first indication information are both carried in the same MAC-CE signaling.
Under the condition that the second indication information and the first indication information are carried in different types of instructions or carried in the same type but not the same instruction, the sequence of the base station for sending the first indication information and the second indication information is not limited, and the sequence of the terminal for receiving the first indication information and the second indication information is not limited.
S430, the terminal configures, according to the first indication information and the second indication information, transmission beams of multiple signal resources in the first signal resource set identified by the first identifier as a first transmission beam.
This step can refer to S220, which is not described herein.
S440, the terminal transmits signals using the plurality of signal resources, wherein a transmission beam of the plurality of signal resources is the first transmission beam.
This step can be referred to as S230, and is not described herein.
In the communication method, the terminal may also determine a transmission beam of the plurality of signal resources in the first set of signal resources as the first transmission beam, based on the first indication information and the second indication information. Compared with the configuration of only the first signal resource according to one piece of information, the other signal resources in the first signal resource set do not need to be reconfigured, so that signaling overhead can be saved, and the updated transmission beam can be used for transmitting signals more quickly, thereby reducing the transmission delay of other signals in the first signal resource set.
It should be understood that other relevant contents in fig. 2 may also be included in the present embodiment, for example, the relevant contents of the transmission power may be included, and the details are not described herein again for brevity.
Taking the first indication information carried in the MAC-CE signaling, where the first signal resource is an aperiodic SRS resource, the first signal resource set is an SRS resource set corresponding to an antenna switching function, the base station sends the second indication information to the terminal to explicitly indicate the terminal, and the first indication information and the second indication information are carried in the same signaling as an example, with reference to fig. 5, the communication method in fig. 4 is further described.
S510, the base station configures an aperiodic SRS resource set through RRC signaling. And the terminal receives the RRC signaling, interprets the RRC signaling and configures an aperiodic SRS resource set according to the RRC signaling.
This step can refer to the related implementation in 3GPP R15, and is not described herein again.
S520, the base station sends the beam indication updating information and the updating mode indication information of the aperiodic SRS through MAC-CE signaling. And the terminal receives and interprets the MAC-CE so as to acquire the SRS resource needing to be updated and the transmission beam. The beam indication update information is the first indication information.
The beam indication updating information comprises SRS resource identification and sending beam indication information. The update mode indication information is used to indicate whether the beam indication update information is used to update the signal resources or to update the set of signal resources. When the update mode indication information indicates that the beam indication update information is used to update the signal resource set, the update mode indication information is the second indication information in S420.
S530, the terminal determines the transmission beam of the SRS resource according to the function of the SRS resource set configured in S510 and the transmission beam and the updating mode indicated by the MAC-CE signaling in S520.
For example, if the terminal determines the updated signal resource set according to the update mode indication information, the terminal searches for an SRS resource set identifier through the SRS resource identifier to determine an SRS resource set to which the SRS resource belongs, updates the transmission beams of all SRS resources in the SRS resource set to the transmission beams indicated in S520, and transmits SRS signals corresponding to all SRS resources in the SRS resource set by using the transmission beams; if the terminal determines to update the signal resource according to the update mode indication information, the terminal transmits the SRS signal corresponding to the SRS resource only using the transmission beam indicated in S520.
For example, if the terminal determines to update the signal resource set according to the update mode indication information, the terminal searches for an SRS resource set identifier through the SRS resource identifier to determine an SRS resource set to which the SRS resource belongs, and determines a function of the SRS resource set to which the SRS resource belongs through "use"; if the "use" of the SRS resource set is "antenna switch", the terminal updates the transmission beams of all SRS resources in the SRS resource set to the transmission beams indicated in S520, and transmits SRS signals corresponding to all SRS resources in the SRS resource set by using the transmission beams; if the "usage" of the SRS resource set is "beam management", "codebook", or "noncodeebook", the terminal transmits the SRS signal corresponding to the SRS resource only by using the transmission beam indicated in S520. If the terminal determines to update the signal resource according to the update mode indication information, the terminal transmits the SRS signal corresponding to the SRS resource only using the transmission beam indicated in S520.
And S540, the terminal determines the sending power of the SRS resource according to the sending beam indication information and the updating mode indication information in the MAC-CE signaling in the S520.
For example, if the reference signal included in the transmission beam indication is a downlink signal, such as an SSB or a CSI-RS, the terminal may estimate the downlink path loss through the SSB or the CSI-RS, and further calculate the uplink transmission power. The method for calculating the transmission power may refer to the SRS transmission power calculation method in 3GPP R15.
For example, if the terminal determines the updated signal resource set according to the update mode indication information, the terminal searches for an SRS resource set identifier through the SRS resource identifier to determine an SRS resource set to which the SRS resource belongs, updates the transmission power of all SRS resources in the SRS resource set to the transmission power calculated in the step, and transmits SRS signals corresponding to all SRS resources in the SRS resource set by using the transmission power; if the terminal determines to update the signal resource according to the update mode indication information, the terminal transmits the SRS signal corresponding to the SRS resource only by using the transmission power calculated in the step.
For example, if the terminal determines to update the signal resource set according to the update mode indication information, the terminal searches for an SRS resource set identifier through the SRS resource identifier to determine an SRS resource set to which the SRS resource belongs, and determines a function of the SRS resource set to which the SRS resource belongs through "use"; if the "use" of the SRS resource set is "antenna switch", the terminal updates the transmission power of all SRS resources in the SRS resource set to the transmission power calculated in the step, and transmits SRS signals corresponding to all SRS resources in the SRS resource set by using the transmission power; if the "usage" of the SRS resource set is "beam management", "codebook", or "nocodewood", the terminal transmits the SRS signal corresponding to the SRS resource using only the transmission power calculated in this step. If the terminal determines to update the signal resource according to the update mode indication information, the terminal transmits the SRS signal corresponding to the SRS resource only by using the transmission power calculated in the step.
S550, the terminal transmits the signal using the SRS resource in the SRS resource set, the transmission beam in the SRS resource is updated to the transmission beam indicated in S520 in S530, and the transmission power in the SRS resource is updated to the transmission power calculated in S540.
That is, when transmitting a signal using the SRS resource in the SRS resource set, the transmission beam used is the transmission beam indicated in S520, and the transmission power used is the transmission power calculated in S540.
It should be understood that in the embodiment shown in fig. 5, S540 may not be included, or S530 and S540 may not have a chronological order.
The application also provides a communication method, which comprises the following steps: receiving first indication information indicating that a reception beam of the first signal resource is configured as a first beam; determining a receiving beam of a plurality of signal resources in a first signal resource set to which a first signal resource belongs as a first receiving beam according to the first indication information; receiving signals using the plurality of signal resources, a receive beam of the plurality of signal resources being a first receive beam.
In the communication method, although the first indication information indicates that the receiving beam of the first signal resource is configured as the first receiving beam, the receiving beams of the plurality of signal resources including the first signal resource in the first signal resource set to which the first signal resource belongs are all determined as the first receiving beam according to the first indication information, so that the time delay and the signaling overhead for configuring the receiving beams of other signal resources in the plurality of signal resources can be saved.
Wherein the first signal resource may be a CSR-RS resource. The function of the first set of signal resources may be a time frequency Tracking (TRS) function, and the function may be embodied in a protocol in a manner that the set of CSI-RS resources is configured as TRS-Info ═ true. The function of the first set of signal resources may also be a terminal beam scanning function (P3), which may be embodied in a protocol in such a way that the set of CSI-RS resources is configured to be repetition on.
Optionally, the first signal resource may also be a control channel resource set (CORESET). The first set of signal resources may function as a UE-specific core or a common core. For example, when the first set of signal resources functions as a UE-specific core, the first indication information is used to indicate that a reception beam of one UE-specific core is configured as a first beam; and according to the first indication information, the terminal determines all the receiving beams of the UE-specific CORESET as the first beam. For example, when the first set of signal resources functions as a common CORESET, the first indication information is used to indicate that a reception beam of one common CORESET is configured as the first beam; according to the first indication information, the terminal determines all common CORESET receiving beams as first beams.
The communication method may refer to the foregoing communication method, and the difference is that the foregoing communication method configures a transmission beam, the present communication method configures a reception beam, the foregoing communication method configures a transmission beam of a signal resource and then transmits a signal using the signal resource, and the present communication method configures a reception beam of the signal resource and then receives a signal using the signal resource.
All communication methods proposed by the present application can be summarized as follows: receiving first indication information, wherein the first indication information is used for indicating that a beam in the first signal resource is configured as a first beam; determining a beam in a plurality of signal resources including a first signal resource in a first signal resource set to which the first signal resource belongs as the first beam according to the first indication information; communicating using the plurality of signal resources.
The first beam may be a transmission beam or a reception beam. For example, when the first signal resource is an aperiodic SRS resource, the first beam is a transmission beam; and when the first signal resource is CRI-RS resource, the first wave beam is receiving wave beam.
When the first beam is a transmission beam, the communicating according to the plurality of signal resources may include: transmitting a signal according to the plurality of signal resources; when the first beam is a receive beam, communicating according to the plurality of signal resources may include: signals are received based on the plurality of signal resources.
From another perspective, in the prior art, MAC-CE based spatial relationship updates are introduced for aperiodic SRS at each resource level, which results in multiple MAC-CE messages being required when updating the transmission beams in multiple SRS resources. Such a signaling scheme may be redundant in view of the different functionalities of different sets of SRS resources. For example, if the function of SRS resource set configuration is "antenna switching", the probability that resources within the same group will be configured as different transmission beams is low, otherwise the terminal may not know how to switch antennas. Therefore, at least for SRS resources that function as "antenna switching", aperiodic SRS spatial relationship updates for each resource set level based on MAC CEs should also be supported. Explicit and implicit solutions may be considered. For example, an additional explicit spatial relationship may be introduced to indicate that the MAC-CE should update the transmission beam for all SRS resources in the set of SRS resources that function as "switched antennas". Or, it can be said, if the function is "antenna switching" in order to reduce delay, aperiodic SRS spatial relationship update at the MAC CE based resource set level is supported.

The MAC-CE signaling shown in fig. 14 sequentially includes the following fields: c, Component Carrier (CC) ID of SRS Resource (SRS Resource), BWP ID of SRS Resource, function indication information, SRS Resource ID, F, Resource ID (i.e. indicating spatial relationship), R, CC ID of Resource, BWP ID of Resource.

One of the two CSI-RS resources is a CSI-RS resource for beam management, for example, the RRC parameter of the CSI-RS resource configures a repetition (repetition) field; the other of the two CSI-RS resources is the CSI-RS resource used as the tracking reference signal, for example, the RRC parameter of the CSI-RS resource configures the TRS field.
After receiving the MAC-CE, the terminal determines that the corresponding function is antenna switching according to the function indication information, and then the terminal may determine that the number of SRS resource IDs in the MAC-CE is 1 and/or the number of SRS resource IDs is 1, and determine one or more signal resource sets to which the SRS resource IDs belong according to the SRS resource IDs, and set transmission beams of a plurality of signal resources in a first signal resource set of the one or more signal resource sets, which is functionally antenna switching, as a first transmission beam, and set BWPs of the plurality of signal resources as BWPs indicated by the BWP IDs of the resources.
