Description

Communication method and communication device

Technical Field

Background

When the terminal device is used, in order to avoid the terminal device emitting too high electromagnetic energy radiation to cause damage to human body, the radiation amount of the average time-averaged area under a certain distance is generally restricted by a maximum permissible radiation (MPE) standard, so as to ensure the safety of people when using the terminal device.

In order to facilitate understanding of the technical solution of the embodiment of the present application, before the solution of the embodiment of the present application is introduced based on a 5G architecture, some terms or concepts in 5G that may be involved in the embodiment of the present application are first described.

1. Reference signal and reference signal resource

The reference signal may be used for channel measurement or channel estimation, etc. The reference signal resources may be used to configure transmission properties of the reference signal, such as time-frequency resource location, port mapping relationship, power factor, and scrambling code. The transmitting end device may transmit the reference signal based on the reference signal resource, and the receiving end device may receive the reference signal based on the reference signal resource.

The reference signal may include, for example, a channel state information reference signal (CSI-RS), a Synchronization Signal Block (SSB), and a Sounding Reference Signal (SRS). Correspondingly, the reference signal resource may include a CSI-RS resource (CSI-RS resource), an SSB resource, and an SRS resource (SRS resource).

The SSB may also be referred to as a synchronization signal/physical broadcast channel block (SS/PBCH block), and the corresponding SSB resource may also be referred to as a synchronization signal/physical broadcast channel block resource (SS/PBCH block), which may be referred to as SSB resource for short.

In order to distinguish between different reference signal resources, each reference signal resource may correspond to an identification of one reference signal resource, for example, a CSI-RS resource identification (CRI), an SSB resource identification (SSBRI), an SRS Resource Index (SRI). The SSB resource identifier may also be referred to as an SSB identifier (ssbinder).

It should be understood that the above listed reference signals and corresponding reference signal resources are only exemplary and should not constitute any limitation to the present application, which does not exclude the possibility of defining other reference signals in future protocols to achieve the same or similar functions.

2. Beam (beam)

A beam may be understood as a spatial resource, and may refer to a transmission or reception precoding vector having an energy transmission directivity, and the precoding vector can be identified by index information. Beams may also be referred to as spatial filters, or spatial filters or spatial parameters.

The energy transmission directivity may refer to precoding a signal to be transmitted by using a precoding vector, where the signal subjected to precoding has a certain spatial directivity, and the signal subjected to precoding by using the precoding vector has a good receiving power, such as meeting a receiving demodulation signal-to-noise ratio; energy transmission directivity may also refer to the reception of the same signal transmitted from different spatial locations with different received powers through the precoding vector.

Beams can be divided into transmit beams and receive beams, from both transmit and receive perspectives. The transmission beam refers to a beam having directivity transmitted by a multi-antenna using a beamforming technique. The receiving beam also has directivity in the direction of the received signal, and points to the incoming wave direction of the transmitting beam as much as possible, so as to further improve the receiving signal-to-noise ratio and avoid the interference among users.

In the embodiment of the present application, the beam, the reference signal resource, the Transmission Configuration Index (TCI), or the spatial relationship (spatial relationship), the spatial filter, the analog phase parameter, and the like represent the same content.

Therefore, the terms described above in the embodiments of the present application may be substituted for each other.

3. Beam management

And beam management, including beam training, beam measurement and reporting, beam indication of each signal or channel, and the like. The uplink and downlink signals or channel beam indications are briefly described below, respectively.

For example, for a Physical Downlink Control Channel (PDCCH) beam indication, a Radio Resource Control (RRC) signaling may be used to configure a beam resource pool, and one of the beams may be activated through a medium access control-control element (MAC-CE) signaling to indicate a PDCCH beam. For another example, for a Physical Downlink Shared Channel (PDSCH) beam indication, a beam resource pool may be configured by using higher layer RRC signaling, a beam subset including a plurality of beams is activated by MAC-CE signaling, and finally a beam of the beam subset is triggered by Downlink Control Information (DCI) to indicate a PDSCH beam. As another example, for periodic and aperiodic channel state information reference signal (CSI-RS) beams, it may be indicated through RRC signaling. As another example, for a semi-persistent CSI-RS beam, this may be indicated by the MAC-CE. For another example, for a Physical Uplink Control Channel (PUCCH) beam indication, a beam resource pool may be configured by using higher layer RRC signaling, and one of the beams may be activated by MAC-CE signaling to indicate a PUCCH beam. As another example, for a Physical Uplink Shared Channel (PUSCH) beam indication, a Sounding Reference Signal (SRS) beam indication may be indicated by an SRI associated therewith. As another example, beam indications for periodic SRS (P-SRS) and aperiodic SRS (AP-SRS) may be indicated by RRC signaling. As another example, for semi-persistent SRS (SP-SRS), RRC signaling may be employed or may be indicated through MAC-CE signaling.

It should be understood that the related contents related to the beam management are only for easy understanding of the description, and do not limit the protection scope of the embodiments of the present application.

4. Antenna panel

Antenna panels, panel for short. Each antenna panel may be configured with one or more receive beams and one or more transmit beams. Thus, an antenna panel may also be understood as a beam group. A communication device, such as a terminal device or a network device, may receive signals via a receive beam on an antenna panel or may transmit signals via a transmit beam on the antenna panel.

The antenna panel is a logical entity and how the physical antennas are mapped to the logical entity is determined by the product implementation. An antenna Panel identification (Panel ID) is defined such that at least the transmitting antenna Panel of the terminal device is visible to the network device, and thus the network device can indicate or obtain the terminal device antenna Panel status based on the ID of the antenna Panel.

An antenna panel may also be implicitly identified by a certain signal or a certain set of signals. Such as may be represented by constraining some transmission properties of the signal and the set of signals. For example, in the Rel-15 protocol, the behavior of restricting SRS resource sets (SRS resource sets) "SRS resources belonging to the same SRS resource set cannot be transmitted simultaneously, and SRS resources belonging to different SRS resource sets can be transmitted simultaneously" shows that beams of the same antenna panel cannot be transmitted simultaneously, and beams of different antenna panels can be transmitted simultaneously.

For example, one antenna panel may correspond to one SRS resource set ID, that is, one SRS resource set ID may be used to indicate one antenna panel. Alternatively, the ID of the antenna panel may be directly associated with the reference signal resource or set of reference signal resources. Alternatively, the ID of the antenna panel may be allocated for a target reference signal resource or a set of reference signal resources. Alternatively, the ID of the antenna panel may be additionally configured in spatial relationship (spatial relationship) information.

When the terminal device reports the capability (represented by the candidate value or candidate value set) to the network device, the terminal device may report information of the panel in a hidden manner, for example, a measurement result of the panel. The capability component may include a maximum SRS antenna port (SRS port). The terminal carries the capability index in the report of the measurement report. The base station can carry out scheduling transmission based on panel according to the capability index, the reported reference signal and the measured value thereof. Furthermore, the maximum SRS antenna port that limits the capability component must be different.

Therefore, the antenna panel in the embodiment of the present application can be represented by any one of the following representation methods: a candidate antenna Panel, a candidate antenna Panel Set, a candidate ID, SRS resource Set, or other terms that may identify or characterize or identify the antenna Panel or terms that have an association with the antenna Panel.

It should be understood that the related contents of the antenna panel are only for easy understanding of the description, and do not limit the protection scope of the embodiments of the present application. For example, in future protocols, when the ID of the antenna panel is improved, the method is still applicable to the embodiment of the present application.

5. Maximum allowable radiation (dose) (MPE)

When the terminal equipment is used, the transmitting antenna is quite close to the brain or other parts of a human body, so that the terminal equipment is generally restricted by some standards to avoid the damage to the human body caused by the radiation of excessive electromagnetic energy, and the safety of people when the terminal equipment is used is ensured. For example, MPE, or radio frequency radiation maximum allowable values (RF exposure definitions), or Specific Absorption Rate (SAR), or radio frequency radiation (RF emission), etc. may be used to represent that the constraints on the radiation requirements of the human body are satisfied. Hereinafter, for ease of understanding, description will be made mainly of MPE.

Typically the MPE constraint index is the average amount of area radiation over an average time at a distance. With respect to specific constraint requirements, reference may be made to the constraint requirements given by the international commission on non-ionizing radiation protection (ICNIRP) and the Federal Communications Commission (FCC). By way of illustration, tables 1 and 2 show two possible ways of constraining.

TABLE 1

TABLE 2

Table 1 showsA simple constraint is made, namely the frequency (f) is considered _ref ) Power Density (PD), statistical area, and statistical time. In practice, the MPE constraints will also typically take into account body distance and antenna array factors, as shown in Table 2.

As shown in table 2, taking the frequency f =10GHz as an example, when a 2 × 2 antenna array is deployed and the array area (array area) is 9cm2, when it is satisfied that a terminal device (such as portable applications) is away from a human body d =0.5cm, the ICNIRP constraint is met, the maximum transmit power (maximum transmitted power) is 13dBm, and the maximum Equivalent Isotropic Radiated Power (EIRP) (or effective isotropic radiated power) (maximum EIRP) is 24dBm. The example does not consider time averaging and the terminal device can be considered to transmit continuously.

The MPE constraints take into account the amount of radiation over the average time, so when radiation is not sustained, the amount of radiation can increase. Taking table 2 as an example, the given transmission power and EIRP constraint are both indexes under continuous transmission, that is, indexes with a duty cycle (or duty ratio) of 100%; if the uplink transmission duty cycle decreases over a period of time, the corresponding transmit power or EIRP may increase. For example, if the uplink transmission duty cycle is reduced to 25% over a period of time (e.g., under TDD typical ratio DDDSU), the corresponding transmit power or EIRP may be increased by 6dB.

As can be seen from the above analysis, the MPE constraint considers many factors, such as distance from the human body, transmission power, EIRP, uplink transmission duty ratio (or transmission time ratio), and the like. These factors are entirely implementation-dependent on the terminal device. For example, the body distance may be obtained by a sensor; as another example, transmit power or EIRP may be implemented with power backoff; for another example, the uplink transmission duty cycle may be configured by reporting the capability to the network device so that the network device can perform reasonable configuration, and the like. However, the implementation by a simple terminal device may bring certain problems and risks to the system. For example, power backoff may cause uplink coverage collapse and may also result in Radio Link Failure (RLF) risk of the system; as another example, an uplink transmission duty cycle that is too low may result in an uplink throughput that is too low. In addition, sensors that detect human body distance also face accuracy and precision issues, among other things.

It is understood that the maximum allowable radiation risk mentioned in the embodiments of the present application is understood by those skilled in the art to mean that the radiation intensity exceeds the limit of the legal regulation or standard, or that the radiation power or energy of the terminal device does not meet the requirement of the legal regulation or standard for the maximum allowable radiation.

6. Power Headroom (PH)

In wireless communication, a concept of power headroom is defined, which specifically means a difference between a maximum transmission power allowed by a UE and a transmission power of an uplink data channel obtained by current estimation, where the uplink data channel is a Physical Uplink Shared Channel (PUSCH), and can be simply expressed by a formula: PH = uealllowedmaxtranspower-PuschPower. It indicates how much transmission power the UE can use in addition to the transmission power used for the current PUSCH transmission. Since the calculation of PH requires the use of PUSCH transmission power, the power headroom may be calculated only in the PUSCH transmission time unit, e.g., subframe. The time unit means a time domain resource with a granularity of a time unit scheduled by the PUSCH, where the time unit may be a subframe, a slot, or a symbol.

The PH may be used as a reference for a network device, such as a base station, to allocate uplink resources, such as Radio Block (RB) resources, according to, for example: if the PH value is negative, it indicates that the current PUSCH transmission power has exceeded the maximum transmission power allowed by the UE, the uplink resource allocation of the UE may be considered to be reduced in the next scheduling; if the PH value is positive, the number of uplink resources allocated subsequently may also continue to increase.

Since one of the meanings of the PH is to provide the network device with use, the concept of Power Headroom Report (PHR) is defined accordingly. The UE may provide, to the network device through the PHR, information about a difference between a maximum transmission power of the UE and a transmission power estimate of an uplink data channel of an activated serving Cell, and also information about a difference between the maximum transmission power of the UE and a transmission power estimate of the uplink data channel and a transmission power estimate of an uplink control channel, where the uplink data channel may include an uplink data channel of at least one of a PCell, a PS Cell, and a PUCCH SCell, and the uplink data channel may include an uplink shared channel UL-SCH. The value of this power headroom may be transmitted by a control element (also referred to as a Control Element (CE)) of a Medium Access Control (MAC) layer, so the MAC control element related to this procedure is also referred to as a PHR control element.

7. MPE constraints

As mentioned above, FCC and ICNIRP have certain constraints on terminal device radiation, such as the radiation power or energy per centimeter at a certain distance from a person should be less than a certain value, and for convenience this constraint is referred to herein as MPE constraint. The terminal device may use different schemes to satisfy the MPE constraints, as illustrated below.

As a possible implementation (denoted as mode 1), the maximum uplink transmission ratio is limited by defining the capability of the static terminal device, that is, the MPE constraint is satisfied by controlling the sending time of the terminal device, and specific format examples are as follows. maxUplinkDutyCycle-FR2 ENUMERATED { n15, n20, n25, n30, n40, n50, n60, n70, n80, n90, n100} OPTIONAL

As another possible implementation (denoted as mode 2), a power backoff mechanism, which may also be referred to as a power management maximum power reduction (P-MPR) mechanism, is defined, and the mechanism satisfies the MPE constraint by controlling the uplink transmission power of the terminal device.

It is understood that the two possible implementations described above can be implemented independently or jointly, depending on the network device configuration and the terminal device implementation. Some possible examples are given below.

For example, if the uplink transmission duty ratio of the terminal device in any 1s evaluation period is greater than the capability reporting value, the terminal device performs power backoff, i.e., P-MPR, according to uplink scheduling. For another example, if the terminal device does not define static capabilities as in mode 1, the terminal device may directly satisfy MPE constraints through power back-off. For another example, the terminal device will power back to meet the MPE constraints under the premise that the uplink transmission ratio is considered to be 100%, so that the terminal device meets the MPE constraints at any time. For another example, the terminal device satisfies the MPE constraint on the uplink transmission ratio under the premise of considering the maximum transmission power or the EIRP, and the terminal device may satisfy the MPE constraint without power back-off in the uplink transmission ratio. For another example, the terminal device increases the uplink transmission duty ratio while considering the maximum transmission power or the EIRP, and does not satisfy the MPE constraint, and the terminal device needs power backoff in the uplink transmission duty ratio and also satisfies the MPE constraint.

As can be seen from the above, by means of the mode 1 and/or the mode 2, the terminal device can be enabled to satisfy the MPE constraint. However, the mode 1 and the mode 2 are two static schemes, and therefore the two modes cannot adapt to a changing channel environment well, the application range of the terminal device is limited, and a dynamic scene cannot be satisfied. On the other hand, limiting the uplink transmission duty ratio may affect the uplink coverage of the terminal device, and performing power backoff may cause uplink performance loss, and may even cause Radio Link Failure (RLF) condition.

As another possible implementation manner (denoted as manner 3), the terminal device reports the MPE status of the terminal device to the network device, and the network device can perform scheduling under consideration based on MPE constraints. The MPE state can refer to the current MPE state of the terminal equipment and can also be the future MPE state of the terminal equipment. The MPE status reported by the terminal device may specifically include one or more of the following items: power headroom or energy headroom of the terminal device; MPE alarm signaling; uplink transmission ratio and power back-off value. The network device may calculate and determine the following scheduling condition through the above-mentioned report of the terminal device.

From the above, by means of the mode 3, the MPE constraint problem can be solved dynamically. However, the above scheme increases dynamic signaling, and the reporting reliability after the MPE occurs is poor. On the other hand, power backoff still results in uplink performance loss and may even result in radio link failure.

As another possible implementation (denoted as mode 4), the base station configures the MPE candidate beam set candidate RS set by RRC to monitor a new available beam. The maximum number of beams in the set of beams is 64. The terminal equipment monitors the quality of the corresponding wave beam in the set and reports the backspacing of different wave beams through the MAC-CE. The base station can know which beams have MPE problems through the report, and can select the switch beams to transmit through the information base station.

As can be seen from the above, by means of the method 4, the back-off amounts of the multiple beams are introduced, so that the power back-off caused by the MPE problem can be provided for the base station, and therefore the base station can select a feasible transmission beam to notify the terminal device according to the corresponding beam and the back-off amount, thereby reducing the uplink performance loss. However, if none of the beams in the set of beams is feasible, the problem of uplink performance loss still cannot be solved.

In view of this, the present application provides a communication method and a communication apparatus, which provide a power backoff value corresponding to a reference signal resource in multiple antenna panels to a network device, so that the network device further optimizes uplink scheduling and resource allocation, thereby improving communication quality and improving user experience.

Fig. 2 illustrates an exemplary flow chart of a method 200 provided by an embodiment of the present application. The method 200 is illustrated below in connection with the various steps in fig. 2.

S201, the terminal equipment determines power back-off values corresponding to a plurality of reference signal resources.

Illustratively, the plurality of reference signal resources includes at least one reference signal resource associated with at least one of the plurality of antenna panels, that is, the plurality of reference signal resources belong to one or more different antenna panels.

As one possible implementation, the reference signal resource includes at least one reference signal resource associated with one of the plurality of antenna panels. For example, in a case that only one antenna panel among the plurality of antenna panels has a maximum allowable radiation risk, the terminal device may report only at least one reference signal resource on the antenna panel having the maximum allowable radiation risk. In this case, the network device may default to other antenna panels belonging to the same group as the antenna panel, without the maximum allowable radiation risk. It is to be understood that antenna panels belonging to the same group refer to multiple antenna panels for simultaneous transmission, and specific reference may be made to the following examples, which are not described in detail herein.

As another possible implementation, the reference signal resource includes at least one reference signal resource associated with a portion (two or more) of the plurality of antenna panels. For example, the terminal device may only report at least one reference signal resource on each of two or more antenna panels where there is a maximum allowed radiation risk.

As yet another possible implementation, the plurality of reference signal resources includes at least one reference signal resource associated with each of the plurality of antenna panels. Some or all of the plurality of antenna panels present the greatest allowable radiation risk.

For example, the terminal device determines power backoff values corresponding to the following reference signal resources: reference signal resource #1, reference signal resource #2, reference signal resource #3, reference signal resource #4, reference signal resource #5, and reference signal resource #6, wherein reference signal resource #1, reference signal resource #2, and reference signal resource #3 belong to antenna panel #1, and reference signal resource #4, reference signal resource #5, and reference signal resource #6 belong to antenna panel #2. It is understood that reference signal resource #1, reference signal resource #2, and reference signal resource #3 may be a part of reference signal resources in antenna panel #1, or may be all of reference signal resources in antenna panel #1, and similarly, reference signal resource #4, reference signal resource #5, and reference signal resource #6 may be a part of reference signal resources in antenna panel #2, or may be all of reference signal resources in antenna panel #2, which is not limited in this application.

It is to be understood that, in an implementation manner, the reference signal resource in the embodiment of the present application may be replaced by any information used for representing the reference signal resource, for example, a beam, which is not limited in this application.

Optionally, the plurality of antenna panels are for simultaneous transmission.

The plurality of antenna panels are used for simultaneous transmission, and may indicate that the plurality of antenna panels are used for simultaneously transmitting and/or simultaneously receiving information, where the information may be data or a reference signal, or indicate that corresponding time domain resources overlap when the plurality of antenna panels transmit and/or receive information, or indicate that the plurality of antenna panels belong to the same panel group, and the terminal device may simultaneously transmit through a plurality of antenna panels in the same panel group, or indicate that the terminal device has the capability of simultaneous multi-panel transmission, or indicate that the terminal device supports simultaneous measurement on multiple panels. That is, the scheme provided by the embodiment of the present application may be applied to a multi-panel simultaneous transmission (STxMP) scenario.

That is, the terminal device determines, in S201, power backoff values corresponding to a plurality of reference signal resources in a plurality of antenna panels in the same panel group based on the plurality of antenna panels.

Alternatively, the panel group may be configured by the network device to the terminal device. For example, before S201, the network device transmits first configuration information to the terminal device, wherein the first configuration information includes information of the plurality of antenna panels and information of reference signal resources included in each of the plurality of antenna panels, and each antenna panel corresponds to the reference signal resource in each antenna panel.

In one implementation, the reference signal resources included in each of the plurality of antenna panels are different from each other. The following examples are given.

Example one, the first configuration information includes the following information:

Candidate RS：{[RS1 RS2 RS3],[RS4 RS5 RS6],[RS7 RS8 RS9],[RS10 RS11 RS12]}

the information indicates that the panel group configured by the network device for the terminal device includes four antenna panels, where the reference signal resource included in the first antenna panel is: RS1, RS2, and RS3, and the reference signal resources included in the second antenna panel are: RS4, RS5, RS6, and the reference signal resource included in the third antenna panel is: RS7, RS8, and RS9, and the reference signal resource included in the fourth antenna panel is: RS10, RS11, RS12. The terminal equipment can simultaneously transmit through any two or more panels in the antenna panel group.

Example two, the first configuration information includes the following information:

Candidate RS：{RS1 RS2 RS3,RS4 RS5 RS6,RS7 RS8 RS9,RS10 RS11 RS12}

Candidate panel：{P1 P1 P1,P2 P2 P2,P3 P3 P3,P4 P4 P4}

the information indicates that the panel group configured by the network device for the terminal device includes four antenna panels (P1, P2, P3, and P4, respectively), and reference signal resources included in the four antenna panels are the same as those in example one, and are not described herein again. Example two differs from example one in that example one indicates the reference signal resource in the same panel by "[ ]", and example two indicates the reference signal resource in the same panel by additional panel indication information (i.e., "Candidate panel" field).

Example three: the first configuration information includes the following information:

Candidate RS：{[RS1 RS2],[RS3 RS4][RS5 RS6],[RS7 RS8]}

Candidate panel：{[P1 P2][P1 P2][P1 P3],[P3 P4]}

the panel group configured by the information identifier network device for the terminal device includes four antenna panels (P1, P2, P3, and P4, respectively), where the reference signal resource included in the antenna panel P1 is: RS1, RS5, and reference signal resources included in the antenna panel P2 are: RS2, RS4, and reference signal resources included in the antenna panel P3 are: RS6, RS7, and the reference signal resources included in the antenna panel P4 are: and (8) RS.

In another implementation, the reference signal resources included in each of the plurality of antenna panels are the same. The following examples are given.

Example four: the first configuration information includes the following information:

Candidate RS：{[RS1 RS2 RS3],[RS1 RS2 RS3],[RS1 RS2 RS3],[RS1 RS2 RS3]}

the information indicates that the panel group configured by the network device for the terminal device includes four antenna panels, where reference signal resources included by the four antenna panels are: RS1, RS2 and RS3. The terminal equipment can simultaneously transmit through any two or more panels in the antenna panel group.

Example five: the first configuration information includes the following information:

Candidate RS：{RS1 RS2 RS3,RS1 RS2 RS3,RS1 RS2 RS3,RS1 RS2 RS3,}

Candidate panel：{P1 P1 P1,P2 P2 P2,P3 P3 P3,P4 P4 P4}

the information indicates that the panel group configured by the network device for the terminal device includes four antenna panels, where reference signal resources included by the four antenna panels are: RS1, RS2 and RS3. Example five differs from example four in that example four indicates the reference signal resource in the same panel by "[ ]", and example five indicates the reference signal resource in the same panel by additional panel indication information (i.e., "Candidate panel" field).

On the other hand, the power back-off value is the uplink transmission power adjusted to meet the maximum allowed radiation requirement, as an example. For example, the uplink transmission power configured by the network device for the terminal device is 10dB, but in order to meet the maximum allowable radiation requirement, the terminal device can only adopt 8dB of power for uplink transmission at the maximum, and at this time, the power back-off value is 2dB. For another example, the power required for uplink transmission by the terminal device should be 10dB, but in order to meet the maximum allowable radiation requirement, the terminal device can only use 8dB of power for uplink transmission at the maximum, and then the power back-off value is 2dB. The information of the power backoff value may refer to the power backoff value itself, or may refer to an index of the power backoff value, which is not limited in this application.

It is to be understood that the maximum allowable radiation requirement is a standard for characterizing the radiation intensity, the maximum allowable radiation requirement is only used as an example for illustration, and other standards that can be used for characterizing the radiation intensity can be applied to the prevention of the embodiments of the present application.

It is further understood that the power back-off value may be the uplink transmission power that has been adjusted by the terminal device to meet the maximum allowed radiation requirement, or may be the uplink transmission power that is predicted to be adjusted by the terminal device according to the maximum allowed radiation requirement, which is not limited in this application.

The terminal device determines the power back-off values corresponding to the multiple reference signal resources, which means that the terminal device determines the power back-off value corresponding to each of the multiple reference signal resources for the reference signal resource. It is understood that the power backoff value corresponding to one reference signal resource may be greater than or equal to 0. When the power back-off value corresponding to one reference signal resource is 0, it indicates that the terminal device performs uplink transmission through the reference signal resource, and the maximum allowable radiation requirement can be met without performing power back-off.

S202, the terminal device sends first information to the network device. Correspondingly, the network device receives the first information from the terminal device.

Illustratively, the first information includes information indicating the plurality of reference signal resources and/or information of power backoff values corresponding to the plurality of reference signal resources.

The information indicating the multiple reference signal resources may be, for example, an Identifier (ID) of the reference signal resource, or a reference signal resource index (index), a specific channel state information reference signal (CSI-RS) resource identifier (CSI-RS) identifier (CRI), or a Synchronization Signal Block (SSB) resource identifier (SSBRI), an SRS resource index (SRS resource index, SRI), or the like.

In a possible implementation manner, the first information is a piece of information, that is, the terminal device reports, to the network device, information of multiple reference signal resources associated with multiple antenna panels and/or information of power backoff values corresponding to the multiple reference signal resources through the piece of information.

In another possible implementation manner, the first information includes multiple pieces of sub information, that is, the terminal device reports, to the network device, information of multiple reference signal resources associated with multiple antenna panels and/or information of power backoff values corresponding to the multiple reference signal resources through the multiple pieces of sub information. The terminal device may send the multiple pieces of sub information to the network device at the same time, or send the multiple pieces of sub information separately, which is not limited in this application. As an example, the terminal device reports information of at least one reference signal resource associated with at least one antenna panel of the multiple antenna panels and/or information of a power backoff value corresponding to the at least one reference signal resource through multiple pieces of different pieces of sub information, respectively. For example, the plurality of antenna panels includes a first antenna panel and a second antenna panel, the first information includes first sub information and second sub information, wherein the first sub information includes information of at least one first reference signal resource in the first antenna panel and/or information of a power backoff value corresponding to the first reference signal resource, and the second sub information includes information of at least one second reference signal resource in the second antenna panel and/or information of a power backoff value corresponding to the at least one second reference signal resource. Therefore, the terminal device sending the first information to the network device may include the terminal device sending the first sub information and the second sub information to the network device.

Optionally, the first information may further include first indication information, where the first indication information is used to indicate that the first information is information of antenna panel granularity or multiple antenna panel granularity, or the first indication information is information determined based on an antenna panel or multiple antenna panels, or the first indication information is used to indicate that the first information includes information associated with multiple reference signal resources in multiple antenna panels, or the first indication information is used to indicate that the first information corresponds to multiple antenna panels, or the first indication information is used to indicate that the first information is information associated with a maximum allowed radiation requirement generated based on a manner specified by Rel-18. The network device may identify the first information based on the first indication information.

Optionally, the first information may further include second indication information, where the second indication information is used to indicate that the multiple antenna panels belong to the same panel group, or the second indication information is used to indicate that the multiple antenna panels are used for simultaneous transmission. The network device may determine which antenna panels belong to the same panel group according to the second indication information, and the network device may switch the terminal device from one antenna panel to another antenna panel belonging to the same panel group as the antenna panel according to actual needs.

Optionally, the first information may further include information of resources corresponding to the panel group of the plurality of antenna panels and/or measurement results of the resources corresponding to the panel group.

Optionally, the first information may further include an identification of the plurality of antenna panels, or an index of the plurality of antenna panels.

Optionally, the first information may also be used to indicate one or more of: the power margin of the terminal equipment, the uplink transmission ratio corresponding to each reference signal resource in the plurality of reference signal resources, and the maximum allowable radiation alarm information corresponding to each reference signal resource in the plurality of reference signal resources are included.

Optionally, the first information may further include third indication information, where the third indication information is used to indicate whether each antenna panel in the plurality of antenna panels has a maximum allowable radiation risk.

Optionally, the first information may further include fourth indication information, where the fourth indication information is used to indicate whether information of a power backoff value corresponding to each of the plurality of reference signal resources is included in the first information.

Optionally, the first information may further include fifth indication information, where the fifth indication information is used to indicate whether information of a resource corresponding to each of the multiple reference signal resources is included in the first information.

Optionally, the first information may be carried in MAC-CE signaling. One possible format of the MAC-CE is illustrated below in connection with fig. 3-5.

Fig. 3 shows a possible MAC-CE format provided by an embodiment of the present application. The parameters shown in fig. 3 are exemplified below.

In the example shown in fig. 3, information of a plurality of reference signal resources in two antenna panels (i.e., antenna panel #1 and antenna panel # 2) and/or information of power backoff values corresponding to the plurality of reference signal resources are included.

The R field is a reserved field and may be set to 0 by default.

In one possible implementation, the first information may be indicated as information of the multi-antenna panel granularity by an R field of the diagonal section line part in fig. 3, that is, in one implementation, the R field may correspond to the first indication information. For example, when the R field is set to "1", it indicates that the information reported by the terminal device through the MAC-CE is information of the antenna panel granularity, and when the R field is "0", it indicates that the information reported by the terminal device through the MAC-CE is not information of the antenna panel granularity. Or, by adding another field, it may be indicated that the first information is information of a multi-antenna panel granularity, which is not limited in this application.

In one possible implementation, it may be indicated by an R field of a diamond-shaped cross-sectional line portion in fig. 3 that the antenna panel #1 and the antenna panel #2 belong to the same panel group, that is, the R field may correspond to the above-described second indication information. For example, setting the R field corresponding to antenna panel #1 and the R field corresponding to antenna panel #2 to the same value (which may be a panel group identification, for example) indicates that antenna panel #1 and antenna panel #2 belong to the same panel group. Alternatively, by adding another field, it may be indicated that the antenna panel #1 and the antenna panel #2 belong to the same panel group, which is not limited in this application.

In one possible implementation, the identities of antenna panel #1 and antenna panel #2 may be carried by the R field of the diamond-shaped cross-sectional line portion in fig. 3. For example, in the example shown in fig. 4, the R field corresponding to antenna panel #1 carries the identity of antenna panel # 1: panel ID #1, the R field corresponding to antenna Panel #2 carries the identity of antenna Panel # 2: panel ID #2.

It is understood that the Panel ID in the embodiment of the present application may refer to any information for identifying an antenna Panel, for example, an antenna Panel index (Panel index), or a reference signal resource index (e.g., SSBRI or CRI). Illustratively, one panel set includes the following antenna panels: panel 5, panel 3, panel 4, panel 1. When the Panel index is 1, then the Panel index indicates Panel 5.

The PH field is used to indicate a power headroom of the terminal device.

P _CMAX,f,c The field is used for indicating the maximum output power configured by the terminal device for calculating the PH.

The MPE field is used to indicate a power backoff value. For example, in the information corresponding to the antenna panel #1, MPE1-MPE4 are respectively used for indicating power back-off values corresponding to 4 reference signal resources in the antenna panel # 1; in the information corresponding to the antenna panel #2, MPE1-MPE4 are used to indicate power back-off values corresponding to 4 reference signal resources in the antenna panel #2, respectively.

The SSBRIi or CRIi field is used to identify candidate reference signal resources. For example, in the information corresponding to the antenna panel #1, SSBRI1 or CRI1 to SSBRI4 or CRI4 are respectively used to indicate four reference signal resources in the antenna panel # 1; in the information corresponding to the antenna panel #2, SSBRI1 or CRI1 to SSBRI4 or CRI4 are respectively used to indicate four reference signal resources in the antenna panel #2.

The Bi field is used to indicate whether information of the candidate reference signal resource indicated by the SSBRIi or CRIi field exists. For example, the B1 field is set to 1, indicating that there is a first octet containing SSBRI1 or CRI 1; the B2 field is set to 1 indicating that there is a second octet containing SSBRI1 or CRI1, and so on. I.e., the Bi field may correspond to the fifth indication information described above.

The Pi field is used to indicate whether a power backoff value corresponding to the candidate reference signal resource indicated by the SSBRIi or CRIi field exists. For example, to meet the maximum allowed radiation requirement, the P field is set to 0 if the applied power backoff value is less than the preset P _ MPR _00, and is set to 1 otherwise. I.e., the Pi field may correspond to the fourth indication information described above.

Optionally, other fields may be added to indicate whether the antenna panel #1 and the antenna panel #2 have the greatest risk of allowing radiation. For example, in the example shown in fig. 5, whether or not there is a maximum allowable radiation risk for the antenna panels #1 and #2 may be indicated by a "case index" field, i.e., the "case index" field may correspond to the third indication information described above. For example, when the "case index" field is "(1, 0)", it indicates that the antenna panel #1 has the maximum allowable radiation risk, and the antenna panel #2 has no maximum allowable radiation risk; when the "case index" field is "(0, 1)", it indicates that there is no maximum allowable radiation risk for antenna panel #1 and that there is a maximum allowable radiation risk for antenna panel # 2; when the "case index" field is "(1, 1)", it indicates that the antenna panel #1 has the maximum allowable radiation risk, and the antenna panel #2 also has the maximum allowable radiation risk; when the "case index" field is "(0, 0)", it means that there is no maximum allowable radiation risk for both antenna panel #1 and antenna panel #2. The network device may switch the terminal device from the panel with the maximum allowable radiation risk to the panel without the maximum allowable radiation risk according to the "case index" field.

The above example is described by taking the first information bearer and the MAC CE signaling as examples, but it should be understood that the first information may also be carried in other signaling, and the application is not limited thereto.
