[0126] Currently, for uplink transmission, in order to meet the scheduling requirement of the network, a power headroom report (PHR) needs to be reported. The PHR reflects the available power of the terminal, i.e., the power headroom. The PHR includes multiple types, for example, type 1 PHR is mainly related to a physical uplink shared channel (PUSCH), and type 3 PHR is mainly related to a sounding reference signal (SRS).

[0127] The content reported in the PHR includes:

[0128] The maximum power that can be transmitted on each cell;

[0129] The power headroom (PH) after the UE transmits an uplink control channel (such as a physical uplink control channel (PUCCH)) on each cell.

[0130] The power headroom after the UE transmits an uplink data channel (such as a PUSCH) on each cell.

[0131] The power headroom after the UE transmits an uplink sounding channel (such as an SRS) on each cell.

[0132] Among them, if the UE has a real physical channel transmission, the power headroom after the real physical channel transmission is reported. If the UE does not have a real physical channel transmission, the power headroom after the reference (or virtual) transmission of the physical channel is reported.

[0133] In a communication system, a communication scenario supporting single transmission and receiving point (S-TRP) and multi transmission and receiving point (TRP) is supported. The multi transmission and receiving point (TRP) includes a deployment scenario of downlink single transmission and receiving point (S-TRP) and uplink multi transmission and receiving point (M-TRP), which can also be referred to as an asymmetric M-TRP scenario. That is, by deploying a heterogeneous network to realize asymmetric M-TRP transmission, uplink coverage and throughput can be improved. The heterogeneous network includes, for example, a master next generation NodeB (gNB) and a micro node for uplink transmission only, which can be referred to as an uplink only TRP (UL only TRP). The master gNB for uplink and downlink transmission can also be referred to as a downlink TRP (DL TRP)

[0134] For the convenience of understanding, the present disclosure introduces the following concepts.

[0135] 1) M-TRP transmission: In order to improve the coverage of the cell edge, provide more balanced service quality in the service area, multi-point cooperation is still an important technical means in the new radio (NR) system. From the network form point of view, the network deployment in the way of a large number of distributed access points + baseband centralized processing will be more conducive to providing balanced user experience rate, and significantly reducing the delay and signaling overhead caused by handover. With the increase of frequency band, from the perspective of ensuring network coverage, relatively dense access point deployment is also needed. In high frequency band, with the improvement of the integration of active antenna devices, it will be more inclined to use modular active antenna array. The antenna array of each TRP can be divided into several relatively independent antenna panels, so the form and port number of the whole array can be flexibly adjusted according to the deployment scene and business demand. The antenna panels or TRPs can also be connected by optical fiber for more flexible distributed deployment. In the millimeter wave band, with the decrease of wavelength, the blocking effect of obstacles such as human body or vehicle will be more significant. In this case, from the perspective of guaranteeing the robustness of link connection, the cooperation between multiple TRPs or panels can also be used to transmit / receive from multiple angles of multiple beams, thereby reducing the adverse effects of blocking effect.

[0136] According to the mapping relationship of the transmitted signal stream to the multiple TRPs / panels, the multi-point cooperation transmission technology can be divided into coherent and non-coherent transmission. Among them, in the coherent transmission, each data layer is mapped to multiple TRPs / panels through a weight vector. In the non-coherent transmission, each data stream is only mapped to part of the TRP / panel. The coherent transmission has higher requirements for the synchronization between the transmission points and the transmission capacity of the backhaul link, and is more sensitive to many non-ideal factors in the real deployment conditions. In contrast, non-coherent transmission is less affected by the above factors, so it is the key consideration scheme of multi-point transmission technology.

[0137] For uplink, the physical uplink shared channel (PUSCH) facing different TRPs may have very different actual channel characteristics, so it is considered that the quasi co-location type D (QCL-D) of the PUSCH in different transmission directions is different.

[0138] 2) Transmission configuration indicator state (TCI state) indicates: the standard indicates the downlink TCI state or joint TCI state for the UE to determine the downlink transmission beam, and the uplink TCI state or joint TCI state for the UE to determine the uplink beam. Here, the downlink beam refers to the beam of the user-specific physical downlink shared channel (PDSCH) and all / part of the PDCCH in a control channel (CC), and the uplink beam refers to the uplink transmission space filter based on the dynamic authorization / configurable authorization PUSCH and all or part of the dedicated PUCCH resource of a CC.

[0139] For the downlink TCI state and joint TCI state in the independent beam indication, a TCI state pool is used.

[0140] For the case of joint beam indication, the TCI field only needs to indicate a joint TCI state, which is used to determine the uplink and downlink transmission beams. However, for the case of independent beam indication, the downlink transmission beam and the uplink transmission beam are no longer the same and need to be indicated respectively. Moreover, there are three scenarios: the downlink transmission beam and the uplink transmission beam need to be indicated for the user at the same time, only the downlink transmission beam needs to be indicated for the user, or only the uplink transmission beam needs to be indicated for the user. Therefore, the mapping relationship between the TCI field and the TCI state in the DCI format 1_1 / 1_2 (DCI formats 1_1 / 1_2) in the case of independent beam indication is as follows:

[0141] One code point of the TCI field can correspond to one downlink TCI state and one uplink TCI state at the same time;

[0142] One code point of the TCI field only corresponds to one downlink TCI state, at which time the user keeps the current UL TCI state unchanged;

[0143] One code point of the TCI field only corresponds to one uplink TCI state, at which time the user keeps the current DL TCI state unchanged.

[0144] At present, the defined TCI state indication method is extended. The uplink and downlink TCI state information of at most 2 cooperating TRPs can be indicated at the same time through the TCI state code point in the DCI.

[0145] 3) For the reporting of type 3 PHR:

[0146] Currently, in the asymmetric M-TRP scenario, the UL only TRP path loss estimation is supported by the following method:

[0147] (1) Downlink path loss reference signal (DL PL RS) based downlink path loss estimation, and through the path loss offset value associated with the transmission configuration indicator state (TCI state) of the UL only TRP, the UL only TRP path loss estimation value is obtained and used for the transmission of uplink channels or signals. That is, PL_UL=PL_DL-PL_offset. Wherein, PL_UL is the UL only TRP path loss estimation value, PL_DL is the DL TRP path loss estimation value, and PL_offset is the path loss offset value associated with the TCI state of the UL only TRP.

[0148] (2) Calculate PL_UL through (1). By sending SRS to the UL only TRP, update the change amount PL_offset' relative to PL_UL, and PL_UL'=PL_UL+ / -PL_offset'.

[0149] On the one hand, (1) can be used for UL only TRP path loss estimation. When the transmission power of SRS sent to different TRPs in frequency range (FR) 2 is different, the network device needs to know the SRS transmission power or the difference of the transmission power, and then the transmission power corresponding to the SRS resource / SRS resource set of the corresponding TRP can be reported through the type 3 PHR.

[0150] On the other hand, if the transmitted SRS signal cannot be effectively received by the DL TRP, the UL only TRP path loss estimation through (1) will cause problems, and at this time, (2) is used preferentially, and then the transmission power corresponding to the SRS resource / SRS resource set of the corresponding TRP can also be reported through the type 3 PHR, or the transmission power of SRS is adjusted according to the PHR reported by the terminal for the calculation of (1) (applicable to FR1&FR2).

[0151] And the type 3 PHR reported by the terminal can be used for path loss information estimation of different TRP nodes through SRS, as well as SRS transmission power control (TPC) decision, etc.

[0152] In addition, the terminal needs to send SRS for antenna switching (AS) to the DL TRP, and the sending of the SRS also needs to support reporting type 3 PHR.

[0153] Therefore, the present disclosure provides a communication method, by which a terminal sends a PHR to a network device, the PHR including at least one of type 1 and type 3, so that in the case that the terminal has the capability of sending type 1 PHR and type 3 PHR on the same carrier, at least one of type 1 PHR and type 3 PHR can be reported more flexibly, and the communication efficiency is improved.

[0172] In some embodiments, the terminal 101 has the capability of transmitting the Type 1 PHR and the Type 3 PHR on the same carrier. The Type 1 PHR corresponds to the transmission of the PUSCH. The Type 3 PHR corresponds to the transmission of the SRS. For example, in the case that the terminal has the capability of transmitting the Type 1 PHR and the Type 3 PHR on the same carrier, the terminal can determine that the PHR includes at least one of the Type 1 PHR and the Type 3 PHR.

[0173] In some embodiments, the SRS supports up to 2 closed-loop power control adjustment (CLPC) states. The closed-loop power adjustment states are included in the power adjustment parameters, and different closed-loop power control adjustment states refer to different power adjustment parameters. For example, in an asymmetric M-TRP scenario, the power adjustment parameters for the terminal to send SRS to the UL only TRP and the power adjustment parameters for the terminal to send SRS to the DL TRP are different, and the SRS can support 2 closed-loop power adjustment states, and different closed-loop power adjustment states can correspond to different TRPs. For example, in the case that the terminal has the capability of sending type 1 PHR and type 3 PHR on the same carrier, and the SRS supports up to 2 closed-loop power control adjustment states, the terminal can determine that the PHR includes at least one of the type 1 PHR and the type 3 PHR.

[0174] In some embodiments, the carrier of the serving cell of the terminal is configured to send PUSCH. For example, in the case that the terminal has the capability of sending type 1 PHR and type 3 PHR on the same carrier, and the SRS supports up to 2 closed-loop power control adjustment states, and the carrier of the serving cell of the terminal is configured to send PUSCH, the terminal can determine that the PHR includes at least one of the type 1 PHR and the type 3 PHR.

[0175] In some embodiments, if the terminal is configured to report a single PHR, the terminal determines that the PHR includes one of the type 1 PHR or the type 3 PHR.

[0176] Optionally, if the type 1 PHR is determined based on actual PUSCH transmission, the PHR includes the type 1 PHR. For example, if the type 1 PHR is determined based on actual PUSCH transmission, it can be directly included in the PHR without considering whether the type 3 PHR is determined based on actual SRS transmission or configured based on reference SRS transmission. It can be understood that if the type 1 PHR is determined based on actual PUSCH transmission, the PH value in the type 1 PHR is an actual PH value, which is relatively reliable, and therefore the type 3 PHR can be ignored. Due to the real-time, accuracy and compatibility of the type 1 PHR, the type 1 PHR is reported to improve communication efficiency.

[0177] Optionally, if the type 1 PHR is determined based on actual PUSCH transmission and the type 3 PHR is determined based on actual SRS transmission, the type 1 PHR is included in the PHR. Wherein, the type 1 PHR is determined based on actual PUSCH transmission, which can be understood as there is actual PUSCH transmission in the time unit of reporting the PHR, and then the terminal can determine the PH value in the type 1 PHR based on the measurement of the actual transmission PUSCH. Correspondingly, the type 3 PHR is determined based on actual SRS transmission, which can be understood as there is actual SRS transmission in the time unit of reporting the PHR, and then the terminal can determine the PH value in the type 3 PHR based on the measurement of the actual transmission SRS. It can be understood that when the type 1 PHR and the type 3 PHR are both determined based on actual transmission, the PH values contained in the type 1 PHR and the type 3 PHR are both actual PH values. Then, due to the real-time, accuracy and compatibility of the type 1 PHR, the type 1 PHR can be selected to be reported preferentially to improve the communication efficiency. Wherein, the time unit can be a time slot, but is not limited thereto.

[0178] Optionally, if the type 1 PHR is determined based on reference PUSCH transmission configuration and the type 3 PHR is determined based on reference SRS transmission configuration, the type 1 PHR is included in the PHR. Wherein, the type 1 is determined based on reference PUSCH transmission configuration, which can be understood as there is no actual PUSCH transmission in the time unit of reporting the PHR, but the type 1 PHR needs to be reported, so a virtual PH value can be determined by measuring the reference PUSCH transmission configuration. Wherein, the reference PUSCH transmission configuration can also be referred to as virtual PUSCH transmission configuration, and the reference PUSCH transmission configuration can be preconfigured by the network device. The network device can preconfigure one or more sets of reference PUSCH transmission configuration. Correspondingly, the type 3 PHR is determined based on reference SRS transmission configuration, which can be understood as there is no actual SRS transmission in the time unit of reporting the PHR, but the type 3 PHR needs to be reported, so a virtual PH value can be determined by measuring the reference SRS transmission configuration. Wherein, the reference SRS transmission configuration can also be referred to as virtual SRS transmission configuration, and the reference SRS transmission configuration can be preconfigured by the network device. The network device can preconfigure one or more sets of reference SRS transmission configuration. It can be understood that when the type 1 PHR and the type 3 PHR are both determined based on reference transmission configuration, the PH values contained in the type 1 PHR and the type 3 PHR are both virtual PH values. Then, due to the real-time, accuracy and compatibility of the type 1 PHR, the type 1 PHR can be selected to be reported preferentially to improve the communication efficiency. Wherein, the time unit can be a time slot, but is not limited thereto.

[0179] Optionally, if the Type 1 PHR is determined based on actual PUSCH transmission and the Type 3 is determined based on reference SRS transmission configuration, the Type 1 PHR is included in the PHR. It can be understood that when the Type 3 PHR contains a virtual PH value and the Type 1 PHR contains an actual PH value, when the terminal is configured to report a single PHR, the PHR containing the actual PH value is selected for reporting to improve the reliability of the PHR.

[0180] Optionally, if the Type 1 PHR is determined based on reference PUSCH transmission configuration and the Type 3 is determined based on actual SRS transmission, the Type 3 PHR is included in the PHR. It can be understood that when the Type 3 PHR contains a virtual PH value and the Type 1 PHR contains an actual PH value, when the terminal is configured to report a single PHR, the PHR containing the actual PH value is selected for reporting to improve the reliability of the PHR.

[0181] In some embodiments, when there are at least two actual SRS transmissions for the terminal, the terminal can select one from the at least two actual SRS transmissions according to a first priority rule, and determine the PH value included in the Type 3 PHR based on the selected SRS transmission. Wherein, the presence of two actual SRS transmissions can be understood as the presence of at least two actual SRS transmissions in the time unit of reporting the PHR.

[0182] In some embodiments, the first priority rule includes at least one of the following: preferentially selecting an SRS transmission corresponding to a first TRP and configured for beam management, the first TRP being used for uplink transmission; preferentially selecting an SRS transmission corresponding to a first TCI state and configured for beam management, the first TCI state being used for uplink transmission; preferentially selecting an SRS transmission corresponding to a second TRP and configured for beam management, the second TRP being used for both uplink transmission and downlink transmission; preferentially selecting an SRS transmission corresponding to a second TCI state and configured for beam management, the second TCI state being used for both uplink transmission and downlink transmission; preferentially selecting an SRS transmission configured for antenna switching; preferentially selecting an SRS transmission with an earlier starting transmission time; SRS transmission configured for codebook transmission has the lowest priority; SRS transmission configured for non-codebook transmission has the lowest priority.

[0183] Optionally, the first priority rule comprises prioritizing the SRS transmission corresponding to the first TRP and configured for beam management. For example, when there are at least two SRS transmissions corresponding to different functions and different TRPs, the SRS transmission corresponding to the first TRP and configured for beam management can be prioritized. For example, the SRS supports two closed loop power adjustment states, the closed loop power adjustment state of the SRS transmission corresponding to the first TRP is i0, and the closed loop power adjustment state of the SRS transmission corresponding to the second TRP is i1. Then the SRS transmission with the closed loop power adjustment state i0 can be prioritized for determining the type 3 PHR. Wherein i0 and i1 are indexes of the closed loop power adjustment state, which can also be referred to as identifiers of the closed loop power adjustment state. Wherein the first TRP is used for uplink transmission, for example, the first TRP can be an UL only TRP in an asymmetric M-TRP, which can also be referred to as a micro node. The second TRP is used for both uplink transmission and downlink transmission. For example, the second TRP can be a master gNB in an asymmetric M-TRP scenario, which can also be referred to as a DL TRP.

[0184] Optionally, the first priority rule comprises prioritizing the SRS transmission corresponding to the first TCI state and configured for beam management. For example, when there are at least two SRS transmissions corresponding to different functions and different TRPs, and the SRS does not support two closed loop power adjustment states, the SRS transmission corresponding to the first TCI state and configured for beam management can be prioritized. For example, when the SRS only supports one closed loop power adjustment state, the SRS transmission sent by the terminal to the first TRP and the SRS transmission sent by the terminal to the second TRP correspond to the same closed loop power adjustment state, so the terminal cannot select the SRS transmission corresponding to the first TRP according to the closed loop power adjustment state. However, the first TRP and the second TRP can correspond to different TCI states, for example, the first TRP corresponds to the first TCI state, and the SRS transmission sent to the first TRP corresponds to the first TCI state. Therefore, the SRS transmission corresponding to the first TCI state can be selected to determine the SRS transmission corresponding to the first TRP.

[0185] Optionally, the first priority rule comprises prioritizing the SRS transmission corresponding to the second TRP and configured for beam management. For example, when there are at least two SRS transmissions corresponding to different functions and different TRPs, the SRS transmission corresponding to the second TRP and configured for beam management can be prioritized. For example, the SRS supports two closed loop power adjustment states, the closed loop power adjustment state of the SRS transmission corresponding to the first TRP is i0, and the closed loop power adjustment state of the SRS transmission corresponding to the second TRP is i1. Then the SRS transmission with the closed loop power adjustment state i0 can be prioritized for determining the type 3 PHR. Wherein i0 and i1 are indexes of the closed loop power adjustment state, which can also be referred to as identifiers of the closed loop power adjustment state. Wherein the first TRP is used for uplink transmission, for example, the first TRP can be an UL only TRP in an asymmetric M-TRP, which can also be referred to as a micro node. The second TRP is used for both uplink transmission and downlink transmission. For example, the second TRP can be a master gNB in an asymmetric M-TRP scenario, which can also be referred to as a DL TRP.

[0186] Optionally, the first priority rule comprises: preferentially selecting the SRS transmission corresponding to the second TCI state, the second TCI state being used for both uplink transmission and downlink transmission, and the SRS transmission corresponding to the second TCI state being used for beam management. For example, when there are at least two SRS transmissions corresponding to different functions, corresponding to different TRPs, and the SRS does not support 2 closed-loop power adjustment states, the SRS transmission corresponding to the second TCI state can be preferentially selected, the SRS transmission corresponding to the second TCI state being used for beam management. The second TCI state can be a TCI state of the second TRP.

[0187] Optionally, the first priority rule comprises: preferentially selecting the SRS transmission corresponding to the second TCI state, the second TCI state being used for both uplink transmission and downlink transmission, and the SRS transmission corresponding to the second TCI state being used for beam management. For example, when there are at least two SRS transmissions corresponding to different functions, corresponding to different TRPs, and the SRS does not support 2 closed-loop power adjustment states, the SRS transmission corresponding to the second TCI state can be preferentially selected, the SRS transmission corresponding to the second TCI state being used for beam management. The second TCI state can be a TCI state of the second TRP.

[0188] Optionally, the first priority rule comprises: preferentially selecting the SRS transmission corresponding to the second TCI state, the second TCI state being used for both uplink transmission and downlink transmission, and the SRS transmission corresponding to the second TCI state being used for beam management. For example, when there are at least two SRS transmissions corresponding to different functions, corresponding to different TRPs, and the SRS does not support 2 closed-loop power adjustment states, the SRS transmission corresponding to the second TCI state can be preferentially selected, the SRS transmission corresponding to the second TCI state being used for beam management. The second TCI state can be a TCI state of the second TRP.

[0189] Optionally, the first priority rule comprises: preferentially selecting the SRS transmission corresponding to the second TCI state, the second TCI state being used for both uplink transmission and downlink transmission, and the SRS transmission corresponding to the second TCI state being used for beam management. For example, when there are at least two SRS transmissions corresponding to different functions, corresponding to different TRPs, and the SRS does not support 2 closed-loop power adjustment states, the SRS transmission corresponding to the second TCI state can be preferentially selected, the SRS transmission corresponding to the second TCI state being used for beam management. The second TCI state can be a TCI state of the second TRP.

[0190] Optionally, the first priority rule comprises: preferentially selecting the SRS transmission corresponding to the second TCI state, the second TCI state being used for both uplink transmission and downlink transmission, and the SRS transmission corresponding to the second TCI state being used for beam management. For example, when there are at least two SRS transmissions corresponding to different functions, corresponding to different TRPs, and the SRS does not support 2 closed-loop power adjustment states, the SRS transmission corresponding to the second TCI state can be preferentially selected, the SRS transmission corresponding to the second TCI state being used for beam management. The second TCI state can be a TCI state of the second TRP.

[0191] Optionally, the first priority rule comprises: preferentially selecting the SRS transmission corresponding to the second TCI state, the second TCI state being used for both uplink transmission and downlink transmission, and the SRS transmission corresponding to the second TCI state being used for beam management. For example, when there are at least two SRS transmissions corresponding to different functions, corresponding to different TRPs, and the SRS does not support 2 closed-loop power adjustment states, the SRS transmission corresponding to the second TCI state can be preferentially selected, the SRS transmission corresponding to the second TCI state being used for beam management. The second TCI state can be a TCI state of the second TRP.

[0192] It can be understood that the above first priority rules can be used in combination. For example, when there are at least two actual SRS transmissions including SRS transmission for function of beam management, SRS transmission for function of antenna switching, SRS transmission for function of codebook or non-codebook transmission, the priority order is: SRS transmission for function of beam management > SRS transmission for function of antenna switching > SRS transmission for function of codebook or non-codebook transmission. Wherein, “>” here means that the SRS transmission before “>” has higher priority than the SRS transmission after “>”. For another example, when there are at least two actual SRS transmissions including SRS transmission for function of beam management and corresponding to the first TRP, SRS transmission for function of beam management and corresponding to the second TRP, SRS transmission for function of antenna switching, SRS transmission for function of codebook or non-codebook transmission, the priority order is: SRS transmission for function of beam management and corresponding to the first TRP > SRS transmission for function of beam management and corresponding to the second TRP > SRS transmission for function of antenna switching > SRS transmission for function of codebook or non-codebook transmission. For another example, when there are at least two actual SRS transmissions including SRS transmission for function of antenna switching, SRS transmission for function of codebook or non-codebook transmission, the priority order is: SRS transmission for function of antenna switching > SRS transmission for function of codebook or non-codebook transmission. The present disclosure does not list all examples, but various combinations are not limited thereto.

[0193] In some embodiments, if the terminal is configured for multiple PHR reporting, the terminal determines that the PHR includes a type 1 PHR and a type 3 PHR.

[0194] In step S2102, the terminal 101 determines the reported quantity in the PHR.

[0195] In some embodiments, if the terminal is configured for single PHR reporting, and the terminal determines that the PHR includes a type 1 PHR, the reported quantity in the PHR includes the PH value corresponding to the type 1 PHR and the maximum transmission power. Wherein, if the type 1 PHR is determined based on actual PUSCH transmission, the PH value corresponding to the type 1 PHR is the actual PH value, and if the type 1 PHR is determined based on reference PUSCH transmission configuration, the PH value corresponding to the type 1 PHR is the virtual PH value. The terminal can also indicate in the PHR through indication information whether the reported PH value is the actual PH value or the virtual PH value.

[0196] In some embodiments, the terminal is configured to report a single PHR, and the terminal determines that the PHR includes a Type 3 PHR. The reported quantity in the PHR includes a PH value corresponding to the Type 3 PHR and a maximum transmission power. If the Type 3 PHR is determined based on actual SRS transmission, the PH value corresponding to the Type 3 PHR is an actual PH value. If the Type 1 PHR is determined based on reference SRS transmission configuration, the PH value corresponding to the Type 3 PHR is a virtual PH value. The terminal can also indicate in the PHR through indication information whether the reported PH value is an actual PH value or a virtual PH value.

[0197] In some embodiments, if the terminal is configured to report multiple PHRs, the terminal determines that the PHR includes a Type 1 PHR and a Type 3 PHR. The reported quantity in the PHR includes a PH value corresponding to the Type 1 PHR and a maximum transmission power, and a PH value corresponding to the Type 3 PHR and a maximum transmission power. Alternatively, the reported quantity in the PHR includes a PH value corresponding to the Type 1 PHR and a PH value corresponding to the Type 3 PHR, and a total maximum transmission power of the terminal.

[0198] Alternatively, the reported quantity in the PHR can include a PH value corresponding to the Type 1 PHR, a maximum transmission power corresponding to the Type 1 PHR, a PH value corresponding to the Type 3 PHR, and a maximum transmission power corresponding to the Type 3 PHR. That is, both the Type 1 PHR and the Type 3 PHR can report corresponding maximum transmission powers.

[0199] Alternatively, the reported quantity in the PHR can include a PH value corresponding to the Type 1 PHR, a PH value corresponding to the Type 3 PHR, and a total maximum transmission power of the terminal. That is, the Type 1 PHR and the Type 3 PHR can report a total maximum transmission power.

[0200] In some embodiments, if the terminal is configured to report multiple PHRs, the Type 1 PHR can be determined based on actual PUSCH transmission or configured based on reference PUSCH transmission. The Type 3 PHR can be determined based on actual SRS transmission or configured based on reference SRS transmission.

[0201] Alternatively, the Type 1 PHR is determined based on actual PUSCH transmission, and the Type 3 PHR is determined based on actual PUSCH transmission. The PH value corresponding to the Type 1 PHR and the PH value corresponding to the Type 3 PHR are both actual PH values. The actual PUCSH transmission and the actual SRS transmission can have different closed-loop power states, or can correspond to different TCI states.

[0202] Optionally, the type 1 PHR is determined based on a reference PUSCH transmission configuration, and the type 3 PHR is determined based on a reference SRS transmission configuration, and the PH value corresponding to the type 1 PHR and the PH value corresponding to the type 3 PHR are both virtual PH values. The terminal can select one reference PUSCH transmission configuration from the pre-defined or pre-configured reference PUSCH transmission configurations, and select one reference SRS transmission configuration from the pre-configured or pre-defined reference SRS transmission configurations. The selected reference PUSCH transmission configuration and the selected reference SRS transmission configuration have different closed-loop power adjustment states or different TCI states, so as to achieve more reported information and more reference significance. For example, the terminal can first select a reference PUSCH transmission configuration, and then select a reference SRS transmission configuration having different closed-loop power adjustment states or different TCI states from the reference PUSCH transmission configuration. For another example, the terminal can first select a reference SRS transmission configuration, and then select a reference PUSCH transmission configuration having different closed-loop power adjustment states or different TCI states from the reference SRS transmission configuration. The pre-defined or pre-configured reference PUSCH transmission configurations can have one or more sets, and correspondingly, the pre-defined or pre-configured reference SRS transmission configurations can have one or more sets. For example, one set of reference PUSCH transmission configurations and one set of reference SRS transmission configurations can be pre-configured (or pre-defined), and the pre-configured (or pre-defined) reference PUSCH transmission configurations and the reference SRS transmission configurations have different closed-loop power adjustment states or different TCI states. The terminal determines the PH value in the type 1 PHR based on the selected reference PUSCH transmission configuration, and the PH value is a virtual PH value. The terminal determines the PH value in the type 3 PHR based on the selected reference SRS transmission configuration, and the PH value is a virtual PH value.

[0203] Optionally, the type 1 PHR is determined based on a reference PUSCH transmission configuration, and the type 3 PHR is determined based on actual SRS transmission, and the PH value corresponding to the type 1 PHR is a virtual PH value, and the PH value corresponding to the type 3 PHR is an actual PH value. The terminal can select a reference PUSCH transmission configuration having different closed-loop power adjustment states from the actual SRS transmission, or select a reference PUSCH transmission configuration having different TCI states from the actual SRS transmission. Alternatively, the network device can also configure a reference PUSCH transmission configuration having different closed-loop power adjustment states or different TCI states from the actual SRS transmission, so as to achieve more reported information and more reference significance. The terminal determines the PH value in the type 1 PHR based on the selected reference PUSCH transmission configuration, and the PH value is a virtual PH value. The terminal determines the PH value in the type 3 PHR based on the actual SRS transmission, and the PH value is an actual PH value.

[0204] Optionally, the type 1 PHR is determined based on the actual PUSCH transmission, and the type 3 PHR is determined based on the reference SRS transmission configuration, the PH value corresponding to the type 1 PHR is the actual PH value, and the PH value corresponding to the type 3 PHR is the virtual PH value. If there are multiple sets of reference SRS transmission configurations preconfigured or predefined, the terminal can select a reference SRS transmission configuration having a different closed-loop power adjustment state from the actual PUSCH transmission, or select a reference PUSCH transmission configuration having a different TCI state from the actual PUSCH transmission, so as to report more information and have more reference significance. Alternatively, the network device can also configure a reference SRS transmission configuration having a different closed-loop power adjustment state or a different TCI state from the actual PUSCH transmission. The terminal can determine the PH value in the type 1 PHR based on the actual PUSCH transmission, and the PH value is the actual PH value. The terminal determines the PH value in the type 3 PHR based on the selected reference SRS transmission configuration, and the PH value is the virtual PH value.

[0205] In some embodiments, if the terminal is configured to multiple PHR reporting, and the type 3 PHR is determined based on the actual SRS transmission, and there are multiple actual SRS transmissions, the terminal selects one from the at least two actual SRS transmissions according to a second priority rule, and determines the PH value included in the type 3 PHR based on the selected SRS transmission.

[0206] Optionally, the type 1 PHR is determined based on the actual PUSCH transmission, the type 3 PHR is determined based on the actual SRS transmission, and there are multiple actual SRS transmissions. The terminal determines the PH value included in the type 1 PHR based on the actual PUSCH transmission. The terminal selects one from the at least two actual SRS transmissions according to a second priority rule, and determines the PH value included in the type 3 PHR based on the selected SRS transmission.

[0207] Optionally, the Type 1 PHR is determined based on a reference PUSCH transmission configuration, the Type 3 PHR is determined based on an actual SRS transmission, and the terminal has multiple actual SRS transmissions. The terminal can select one from the at least two actual SRS transmissions according to a second priority rule, and determine the PH value included in the Type 3 PHR based on the selected SRS transmission. Further, a reference PUSCH transmission configuration having a different closed loop power adjustment state or a different TCI state from the selected actual SRS transmission is selected, and the PH value in the Type 1 PHR is determined based on the selected reference PUSCH transmission configuration. For another example, the terminal first selects a reference PUSCH transmission configuration, and then selects an actual SRS transmission having a different closed loop power adjustment state or a different TCI state from the reference PUSCH transmission configuration from the at least two actual SRS transmissions according to the second priority rule. The second priority rule at this time includes preferentially selecting an SRS transmission having a different closed loop power adjustment state from a PUSCH transmission; or, preferentially selecting an SRS transmission having a different TCI state from a PUSCH transmission.

[0208] In some embodiments, the second priority rule includes at least one of the following: preferentially selecting an SRS transmission having a different closed loop power adjustment state from a PUSCH transmission, the PUSCH transmission being used for determining a Type 1 PHR; preferentially selecting an SRS transmission having a different TCI state from a PUSCH transmission, the PUSCH transmission being used for determining a Type 1 PHR; preferentially selecting an SRS transmission configured for beam management corresponding to a first transmission point (TRP), the first TRP being used for uplink transmission; preferentially selecting an SRS transmission configured for beam management corresponding to a first TCI state, the first TCI state being used for uplink transmission; preferentially selecting an SRS transmission configured for beam management corresponding to a second TRP, the second TRP being used for both uplink transmission and downlink transmission; preferentially selecting an SRS transmission configured for beam management corresponding to a second TCI state, the second TCI state being used for both uplink transmission and downlink transmission; preferentially selecting an SRS transmission configured for antenna switching; preferentially selecting an SRS transmission having an earlier starting transmission time; preferentially selecting an SRS transmission configured for non-codebook transmission; and preferentially selecting an SRS transmission configured for codebook transmission.

[0209] Optionally, the second priority rule comprises prioritizing SRS transmission with different closed loop power adjustment state than PUSCH transmission. For example, for Type 1 PHR based on actual PUSCH transmission, from at least two actual SRS transmissions, the actual SRS transmission with different closed loop power adjustment state than actual PUSCH transmission is prioritized. For another example, for Type 1 PHR based on reference PUSCH transmission configuration, from at least two actual SRS transmissions, the actual SRS transmission with different closed loop power adjustment state than the reference PUSCH transmission configuration is prioritized.

[0210] Optionally, the second priority rule comprises prioritizing SRS transmission with different TCI state than PUSCH transmission. For example, for Type 1 PHR based on actual PUSCH transmission, from at least two actual SRS transmissions, the actual SRS transmission with different TCI state than actual PUSCH transmission is prioritized. For another example, for Type 1 PHR based on reference PUSCH transmission configuration, from at least two actual SRS transmissions, the actual SRS transmission with different TCI state than the reference PUSCH transmission configuration is prioritized.

[0211] Optionally, the second priority rule comprises prioritizing SRS transmission corresponding to a first TRP with a configuration function of beam management. The first TRP is used for uplink transmission. For example, when there are at least two SRS transmissions corresponding to different functions and different TRPs, the SRS transmission with a function of beam management (BM) and corresponding to the first TRP is prioritized for determining the PH value included in Type 3 PHR. For example, SRS supports 2 closed loop power adjustment states, the closed loop power adjustment state of the SRS transmission corresponding to the first TRP is i0, and the closed loop power adjustment state of the second TRP is i1. Then the SRS transmission with the closed loop power adjustment state of i0 is prioritized for determining Type 3 PHR. Wherein, i0 and i1 are indexes of closed loop power adjustment states, which can also be referred to as identifiers of closed loop power adjustment states. Wherein, the first TRP is used for uplink transmission, for example, the first TRP can be an UL only TRP in an asymmetric M-TRP, which can also be referred to as a micro node. The second TRP is used for both uplink transmission and downlink transmission. For example, the second TRP can be a master gNB in an asymmetric M-TRP scenario, which can also be referred to as a DL TRP.

[0212] Optionally, the second priority rule comprises: preferentially selecting the SRS transmission corresponding to the first TCI state and configured to perform the beam management function. For example, when there are at least two SRS transmissions corresponding to different functions and different TRPs, and the SRS does not support two closed-loop power adjustment states, the SRS transmission corresponding to the first TCI state and configured to perform the beam management function can be preferentially selected. When the SRS does not support two closed-loop power adjustment states, for example, only one closed-loop power adjustment state is supported, the SRS transmission sent by the terminal to the first TRP and the SRS transmission sent by the terminal to the second TRP correspond to the same closed-loop power adjustment state. Therefore, the terminal cannot select the SRS transmission corresponding to the first TRP according to the closed-loop power adjustment state. However, the first TRP and the second TRP can correspond to different TCI states. For example, the first TRP corresponds to the first TCI state, and the SRS transmission sent to the first TRP corresponds to the first TCI state. Therefore, the SRS transmission corresponding to the first TCI state can be selected to determine the SRS transmission corresponding to the first TRP.

[0213] Optionally, the second priority rule comprises: preferentially selecting the SRS transmission corresponding to the second TRP and configured to perform the beam management function. The second TRP is used for both uplink transmission and downlink transmission. For example, when there are at least two SRS transmissions corresponding to different functions and different TRPs, the SRS transmission corresponding to the second TRP and configured to perform the beam management function can be preferentially selected to determine the PH value included in the type 3 PHR. In this case,

[0214] Optionally, the second priority rule comprises: preferentially selecting the SRS transmission corresponding to the second TCI state and configured to perform the beam management function. The second TCI state is used for both uplink transmission and downlink transmission. For example, when there are at least two SRS transmissions corresponding to different functions and different TRPs, and the SRS does not support two closed-loop power adjustment states, the SRS transmission corresponding to the second TCI state and configured to perform the beam management function can be preferentially selected. In this case, the second TCI state is used for uplink transmission. For example, the second TCI state can be the TCI state of the second TRP.

[0215] Optionally, the second priority rule comprises: preferentially selecting the SRS transmission configured to perform the antenna switching function. For example, when there are at least two SRS transmissions corresponding to different functions, the SRS transmission configured to perform the antenna switching function can be preferentially selected.

[0216] Optionally, the second priority rule comprises: preferentially selecting the SRS transmission with an earlier starting transmission time. For example, when there are at least two actual SRS transmissions in the time unit for reporting the PHR, the SRS transmission with an earlier starting transmission time can be preferentially selected.

[0217] Optionally, the second priority rule comprises that SRS transmission with later starting transmission time is selected preferentially. For example, if there are at least two actual SRS transmissions in the time unit of reporting PHR, SRS transmission with later starting transmission time is selected preferentially.

[0218] Optionally, the second priority rule comprises that SRS transmission with codebook transmission function has the lowest priority. For example, if there are at least two SRS transmissions corresponding to different functions, SRS transmission with codebook transmission function has the lowest priority, i.e., if there are multiple SRS transmissions with different functions, SRS transmission with codebook function is selected only when other options fail.

[0219] Optionally, the second priority rule comprises that SRS transmission with non-codebook transmission function has the lowest priority. For example, if there are at least two SRS transmissions corresponding to different functions, SRS transmission with non-codebook transmission function has the lowest priority, i.e., if there are multiple SRS transmissions with different functions, SRS transmission with non-codebook function is selected only when other options fail.

[0220] In some embodiments, the embodiments of the present disclosure support the case of a single carrier, for which at least one of type 1 PHR and type 3 PHR can be reported. The case of multiple carriers is also supported, for which at least one of type 1 PHR and type 3 PHR can be reported for each carrier.

[0221] In some embodiments, the terminal can or can not consider a path loss offset value (PL offset) when calculating the PH value. That is, the terminal determines the PH value based on parameters, which can or can not include the PL offset.

[0222] Optionally, if the function of the SRS corresponding to the type 3 PHR is beam management and / or antenna switching, the terminal determines that the parameters do not include the path loss offset value, and calculates the PH value based on the parameters.

For another example, the terminal can be configured to report the reporting quantity of multiple carriers, and the PHR includes the reporting quantity of multiple carriers, i.e., the type 1 PHR includes the PH value and the maximum transmission power corresponding to multiple carriers, and / or the type 3 PHR includes the PH value and the maximum transmission power corresponding to multiple carriers. It can be understood that when the terminal reports one type of PHR, the PHR can include the reporting quantity of one or more carriers (or cells).

[0257] In some embodiments, the PH is calculated as:

[0258] Optionally, according to different usage, whether to count the PL-offset is distinguished. For example, the SRS used for BM and AS does not consider the PL offset configuration when calculating the PH, and the SRS used for CB / NCB needs to consider the PL-offset configuration when calculating the PH.

[0259] Optionally, neither of them counts the PL-offset.

[0260] In some embodiments, when the terminal is configured to single PHR reporting, if both Type 1 and Type 3 power headroom reports are based on respective actual transmissions, the terminal reports Type 1 PHR report.

If either Type 1 report or Type 3 report is based on respective reference transmission, only Type 1 or Type 3 power headroom report based on corresponding actual transmission is reported.

[0261] In some embodiments, if there are 2 SRS actual transmissions simultaneously, the reported SRS transmission for measurement reporting is selected according to predetermined rules. The predetermined rules are as follows:

[0262] Optionally, SRS with function corresponding to UL TRP as BM is preferentially reported.

[0263] Optionally, SRS with function corresponding to DL TRP as BM is preferentially reported.
