The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0063] In some embodiments, a core network device may be a single device comprising one or more network elements, or may be a plurality of devices or device groups, each comprising all or part of one or more network elements. A network element may be virtual or physical. The core network may, for example, comprise at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), or a Next Generation Core (NGC).

Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0065] The following embodiments of the present disclosure may be applied to the communication system 100 shown in Figure 1, or a portion thereof, but are not limited thereto. The entities shown in Figure 1 are illustrative only. The communication system may include all or part of the entities shown in Figure 1, or may include other entities outside of Figure 1. The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only.

[0066] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0067] Optionally, based on the Power Headroom Report (PHR), the terminal can report the instantaneous transmit power used for Physical Uplink Shared Channel (PUSCH) transmissions. The PHR reflects the terminal's available power, i.e., the power headroom, which can be measured and reported to the base station during uplink transmission control.

[0068] Optionally, the terminal sends a PHR when being scheduled for transmission on an uplink shared channel (UL-SCH).

[0069] Optionally, the type 1 PHR is mainly related to the uplink transmission of multiple transmission reception points (multi-TRP, MTRP). The PHR includes the power headroom and the maximum configured transmit power P on the component carrier. Cmax .P Cmax This can be explicitly configured by the network. Because the network knows the modulation and coding scheme at the time the power headroom report is being reported, as well as the resource size allocated by the terminal for transmission, it can determine a valid combination of modulation and coding scheme and allocated resource size. Even when there is no actual PUSCH transmission, the terminal can also report Type 1 Power Headroom (PH).

[0070] The current PHR measurement mechanism is optional and is divided into actual PHR (actual PHR / real type PHR) or virtual PHR (virtual PHR / virtual type PHR). When there is PUSCH transmission, the terminal reports the actual PHR to the base station. If there is no PUSCH transmission, the terminal calculates a PHR based on the pre-defined PUSCH format and sends it to the base station, which is the virtual PHR. The network will determine the terminal's transmission bandwidth and transmission mode based on the terminal's power difference information.

[0071] Optionally, in the enhancement of some versions of the communication protocol, it is expected to achieve simultaneous collaborative transmission in the TRP direction of multiple base stations through multiple antenna panels (panels) to increase the reliability and throughput of the transmission, and at the same time effectively reduce the transmission delay under multiple TRPs, requiring the terminal to have the ability to send multiple beams simultaneously. The transmission of PUSCH can be based on a single physical downlink control channel (Physical Downlink Control Channel, PDCCH), that is, a single downlink control information (Single Downlink Control Information, S-DCI) scheduled multi-antenna panel / TRP transmission, as shown in Figure 2A, or it can be based on different PDCCHs, that is, multiple downlink control information (Multi-Downlink Control Information, M-DCI) scheduled multi-antenna panel / TRP transmission, as shown in Figure 2B. Among them, Figure 2A is a schematic diagram of a multi-antenna panel / TRP transmission scenario based on S-DCI scheduling, and Figure 2B is a schematic diagram of a multi-antenna panel / TRP transmission scenario based on M-DCI scheduling. Optionally, a terminal multi-panel implementation generally configures multiple physical panels. Different panels may have different capabilities, such as having different numbers of sounding reference signal (SRS) ports. The maximum number of data transmission layers supported by each panel may also not be the same. For example, one panel supports a maximum of 2 layers of transmission, while another panel supports a maximum of 4 layers of transmission. The network scheduler will determine whether the terminal is currently suitable for simultaneous uplink transmission of multiple panels. If the terminal is currently suitable for simultaneous uplink transmission of multiple panels and is scheduled at the same time, the network will directly or indirectly indicate the relevant transmission parameters, including terminal-specific beam indication information, the number of data layers used for transmission, the allocation of demodulation reference signal (DMRS) ports used, and precoding indication information.

[0072] Optionally, in the uplink Multiple-In Multiple-Out (MIMO) enhancement of some versions of the communication protocol, it is considered to realize simultaneous uplink transmission for multiple TRPs through multi-panel terminals to further improve the uplink system transmission throughput and transmission reliability. For simultaneous uplink transmission of multi-panel terminals, since each panel of the terminal has an independent power amplifier (PA) implementation structure and can support independent power control processes, the maximum configured transmission power P of the terminal can be defined according to different panels. Cmax , or consider the maximum configured transmit power P of the terminal as a whole CmaxTo support uplink simultaneous transmission from multi-panel (STxMP), PHR reporting can be enhanced.

[0073] FIG3 is an interactive diagram of an uplink communication method according to an embodiment of the present disclosure. As shown in FIG3 , the embodiment of the present disclosure relates to an uplink communication method, which can be used in a communication system 100. The method includes:

[0074] Step S3101: The network device sends first information to the terminal.

[0075] The first information is used to configure the terminal to send a power headroom report PHR in a multi-PHR mode.

[0076] In some embodiments, the network device may configure the terminal to send the power headroom report PHR in a multi-PHR mode through high-layer signaling.

[0077] In some embodiments, the multi-PHR mode may be, for example, twoPHRMode. In the multi-PHR mode, the terminal may report at least two PHRs.

[0078] Step S3102: The terminal receives first information sent by the network device.

[0079] In some embodiments, the terminal may receive first information sent by the network device, and determine, based on the first information, the content configured by the network device for the terminal to support PHR reporting.

[0080] Step S3103: The terminal sends second information to the network device.

[0081] The second information includes a PHR corresponding to at least one of multiple physical uplink shared channels PUSCH.

[0082] Among them, multiple PUSCHs are based on the simultaneous transmission of STxMPs by multiple antenna panels, each PUSCH is associated with a different TRP, or each PUSCH is associated with a different transmission configuration indication state (Transmission Configuration Indication state, TCI state), or each PUSCH is associated with a different control resource set pool index (CORESETPoolIndex), or each PUSCH is associated with a different SRS resource set (SRS resource set).

[0083] For example, among multiple PUSCHs, PUSCH 1 is associated with TRP1, PUSCH 2 is associated with TRP2, PUSCH 3 is associated with TRP3, and so on. Alternatively, PUSCH 1 is associated with TCI state 1, PUSCH 2 is associated with TCI state 2, PUSCH 3 is associated with TCI state 3, and so on. Alternatively, PUSCH 1 is associated with CORESETPoolIndex1, PUSCH 2 is associated with CORESETPoolIndex2, PUSCH 3 is associated with CORESETPoolIndex3, and so on. Alternatively, PUSCH 1 is associated with SRS resource set 1, PUSCH 2 is associated with SRS resource set 2, PUSCH 3 is associated with SRS resource set 3, and so on.

[0084] Optionally, different PUSCH transmissions may support scheduling-based dynamic grant (DG) PUSCH transmission, or support scheduling-free configured grant (CG) PUSCH transmission, which is not limited in the present disclosure.

[0085] In some embodiments of the present disclosure, the terminal may determine a reporting method for a PHR corresponding to at least one PUSCH based on a protocol agreement or third information sent by a network device, wherein the reporting method may be independent reporting or joint reporting.

[0086] It is understandable that it is more reasonable for the protocol to only support independent reporting, that is, it is more reasonable for the protocol to only report the PHR corresponding to at least one PUSCH as independent reporting. The reporting method of the PHR corresponding to at least one PUSCH indicated by the third information sent by the network device can be independent reporting or joint reporting, and this disclosure does not limit this.

[0087] In some embodiments of the present disclosure, the third information may be at least one of Radio Resource Control (RRC) signaling, DCI 0_1 signaling, DCI 0_2 signaling, and DCI 0_3 signaling.

[0088] For example, when the PUSCH is transmitted based on M-DCI STxMP and the network configures multiple PHR modes (such as twoPHRMode) through high-level signaling, different PUSCH transmissions (supporting DG PUSCH transmission based on scheduling and supporting CG PUSCH transmission based on free scheduling) need to be associated with different SRS resource sets / CORESETPoolIndex, and the "separate independent" or "joint" PHR reporting mode is configured through predefined or high-level signaling.

[0089] In some embodiments, in response to the reporting method of the PHR corresponding to at least one PUSCH being independently reported, the second information can be reported through the Media Access Control Control Element (MAC CE) of each PUSCH in multiple PUSCHs configured based on STxMP transmission.

[0090] For example, for the case where the reporting mode of the PHR corresponding to at least one PUSCH is independent reporting (PUSCHs sent by different panels are independent PHR reports), each PUSCH reports the PHR corresponding to each PUSCH through its own MAC CE, which is the same as the existing single transmission reception point (Single TRP, STRP).

[0091] In some embodiments, in response to the reporting method of the PHR corresponding to at least one PUSCH being a joint reporting, the terminal can perform PHR measurements on multiple PUSCHs to obtain the PHR corresponding to each PUSCH; and report the second information to the network device by sending a PHR MAC CE, where the second information includes the PHR corresponding to at least one PUSCH among the multiple PUSCHs.

[0092] The sent PHR MAC CE refers to a MAC CE used to report the PHR corresponding to at least one PUSCH among the multiple PUSCHs included in the second information, and the PUSCH carrying the PHR MAC CE is not any of the aforementioned multiple PUSCHs.

[0093] In the case of joint reporting, the PHR corresponding to at least one PUSCH among multiple PUSCHs can be reported to the network device by sending a PHR MAC CE, which can effectively improve the uplink transmission throughput and transmission reliability.

[0094] In some embodiments, in response to the reporting mode of the PHR corresponding to at least one PUSCH being jointly reported, each PUSCH in the multiple PUSCHs is actually sent in a time slot overlapping with time slot n, where time slot n is the first time slot of the PUSCH carrying the second information, and time slot n is used as the time slot for reporting the PHR, the second information may include the PHR corresponding to each PUSCH, each PHR being an actual PHR, including the power headroom PH and the maximum transmit power P on the component carrier where it is located. Cmax , where the PHR is determined based on the corresponding actually transmitted PUSCH.

[0095] That is, in the case of joint reporting, if each of the multiple PUSCHs is actually transmitted in a time slot overlapping with time slot n, it means that each of the multiple PUSCH transmissions is an actual transmission (actual transmission). At this time, when the terminal reports the second information to the network device by sending a PHR MAC CE, the second information may include the PHR corresponding to each PUSCH, and each PHR is an actual PHR, including PH and P Cmax , and each PHR is determined based on the corresponding actually transmitted PUSCH.

[0096] In some embodiments, in the case where the second information includes a PHR corresponding to each of a plurality of PUSCHs, and each PHR is an actual PHR, since the second information includes a PHR corresponding to each of the plurality of PUSCHs, it is necessary to indicate the correspondence between the PHR and the PUSCH in the second information to determine which PUSCH each PHR belongs to. Optionally, the first PHR included in the second information may be the PHR of the PUSCH corresponding to the first TCI state, and the second PHR included in the second information may be the PHR of the PUSCH corresponding to the second TCI state; or, the first PHR included in the second information may be the PHR of the PUSCH corresponding to the first CORESETPoolIndex, and the second PHR included in the second information may be the PHR of the PUSCH corresponding to the second CORESETPoolIndex; or, the first PHR included in the second information may be the PHR of the PUSCH corresponding to the first SRS resource set, and the second PHR included in the second information may be the PHR of the PUSCH corresponding to the second SRS resource set, wherein the index of the first SRS resource set is less than the index of the second SRS resource set.

[0097] For example, for the case where the reporting mode of the PHR corresponding to at least one PUSCH is joint reporting (the PUSCHs sent by different Panels are joint PHR reporting), if the different PUSCHs corresponding to different panels / TCI states / CORESETPoolIndex / SRS resource sets overlap with the first time slot of the PUSCH carrying the PHR MAC CE, that is, there is overlapping transmission in the time domain on the time slot n, then each PUSCH transmission is actual transmission (actual transmission). At this time, the PHR corresponding to each PUSCH ((actual PHR+actual PHR)) can be reported simultaneously through the second information. Each PHR includes PH and P Cmax , and each PHR is determined based on the corresponding actual transmitted PUSCH. For example, each panel reports PCmax，k and PH, k = {0, 1}, P Cmax，k is the P corresponding to different TCI states Cmax It is further necessary to define the correspondence between the reported PHR and PUSCH, as shown below:

[0098] Option 1: The first PHR included in the second information corresponds to the PUSCH transmission associated with CORESETPoolIndex#0, and the second PHR included in the second information corresponds to the PUSCH transmission associated with CORESETPoolIndex#1;

[0099] Option 2: The first PHR included in the second information corresponds to a PUSCH transmission associated with a smaller SRS resource set Index, and the second PHR included in the second information corresponds to a PUSCH transmission associated with a larger SRS resource set Index.

[0100] In summary, when the reporting method is joint reporting and each PUSCH transmission in multiple PUSCHs is an actual transmission (actual transmission), the PHR (actual PHR+actual PHR) corresponding to each actual transmission (actual transmission) in multiple PUSCHs can be reported simultaneously through the second information to improve the uplink transmission throughput and transmission reliability.

[0101] In some embodiments, in response to the reporting mode of the PHR corresponding to at least one PUSCH being jointly reported, the first PUSCH among the multiple PUSCHs is actually sent in a time slot overlapping with time slot n, and the second PUSCH among the multiple PUSCHs is not sent in a time slot overlapping with time slot n, wherein time slot n is the first time slot of the PUSCH carrying the second information, and when time slot n is used as the time slot for reporting the PHR, the second information may include the PHR corresponding to the first PUSCH and the PHR corresponding to the second PUSCH, the PHR corresponding to the first PUSCH is the actual PHR, and the PHR corresponding to the second PUSCH is the virtual PHR, and each PHR includes the power margin PH and the maximum transmit power P on the component carrier where it is located. Cmax , wherein the PHR corresponding to the first PUSCH is determined based on the corresponding actually transmitted PUSCH, and the PHR corresponding to the second PUSCH is determined based on the corresponding reference PUSCH.

[0102] In some embodiments, in response to the reporting mode of the PHR corresponding to at least one PUSCH being jointly reported, the first PUSCH among the multiple PUSCHs is actually sent in a time slot overlapping with time slot n, and the second PUSCH among the multiple PUSCHs is not sent in a time slot overlapping with time slot n, wherein time slot n is the first time slot of the PUSCH carrying the second information, and when time slot n is used as the time slot for reporting the PHR, the second information may include the PHR corresponding to the first PUSCH and the PHR corresponding to the second PUSCH, the PHR corresponding to the first PUSCH is the actual PHR, the PHR corresponding to the second PUSCH is the virtual PHR, and the PHR corresponding to the first PUSCH includes the power headroom PH and the maximum transmit power P on the component carrier where it is located. Cmax The PHR corresponding to the second PUSCH includes a power headroom PH, wherein the PHR corresponding to the first PUSCH is determined based on the corresponding actually transmitted PUSCH, and the PHR corresponding to the second PUSCH is determined based on the corresponding reference PUSCH.

[0103] In some embodiments, in response to the reporting mode of the PHR corresponding to at least one PUSCH being jointly reported, the first PUSCH among the multiple PUSCHs is actually sent in a time slot overlapping with time slot n, and the second PUSCH among the multiple PUSCHs is not sent in a time slot overlapping with time slot n, wherein time slot n is the first time slot of the PUSCH carrying the second information, and when time slot n is used as the time slot for reporting the PHR, the second information may include the PHR corresponding to the first PUSCH, the PHR is the actual PHR, including the power headroom PH and the maximum transmit power P on the component carrier where it is located. Cmax , where the PHR is determined based on the corresponding actually transmitted PUSCH.

[0104] That is, in the case of joint reporting, if the first PUSCH among multiple PUSCHs is actually sent in a time slot overlapping with time slot n, and the second PUSCH among multiple PUSCHs is not sent in a time slot overlapping with time slot n, it means that the first PUSCH transmission among multiple PUSCHs is actual transmission (actual transmission), and the second PUSCH transmission among multiple PUSCHs is virtual transmission (virtual transmission). At this time, when the terminal reports the second information to the network device by sending a PHR MAC CE, the second information may include the PHR corresponding to the first PUSCH and the PHR corresponding to the second PUSCH, wherein the PHR corresponding to the first PUSCH is the actual PHR, and the PHR corresponding to the second PUSCH is the virtual PHR. The PHR corresponding to the first PUSCH is determined based on the corresponding actually sent PUSCH, and the PHR corresponding to the second PUSCH is determined based on the corresponding reference PUSCH, and the PHR corresponding to the first PUSCH may include PH and P Cmax , the PHR corresponding to the second PUSCH may include PH and P Cmax , or the PHR corresponding to the second PUSCH may only include PH. Or, the second information may only include the PHR corresponding to the first PUSCH, wherein the PHR corresponding to the first PUSCH is the actual PHR, including PH and P Cmax , the PHR corresponding to the first PUSCH is determined based on the corresponding actually transmitted PUSCH.

[0105] It should be noted that, with respect to the situation where the first PUSCH among the above-mentioned multiple PUSCHs is actually sent in a time slot overlapping with time slot n, and the second PUSCH among the multiple PUSCHs is not sent in a time slot overlapping with time slot n, it is not limited whether the second PUSCH among the multiple PUSCHs is actually sent in other time slots.

[0106] In some embodiments, for the case where the above-mentioned second information includes the PHR corresponding to the first PUSCH and the PHR corresponding to the second PUSCH, since the second information includes multiple PHRs, and these multiple PHRs are the PHR corresponding to the first PUSCH and the PHR corresponding to the second PUSCH, it is necessary to indicate the correspondence between the PHR and the PUSCH in the second information to determine which PUSCH each PHR is the PHR of. Optionally, the first PHR included in the second information is the PHR of the PUSCH corresponding to the first TCI state, and the second PHR included in the second information is the PHR of the PUSCH corresponding to the second TCI state; or, the first PHR included in the second information is the PHR of the PUSCH corresponding to the first CORESETPoolIndex, and the second PHR included in the second information is the PHR of the PUSCH corresponding to the second CORESETPoolIndex; or, the first PHR included in the second information is the PHR of the PUSCH corresponding to the first SRS resource set, and the second PHR included in the second information is the PHR of the PUSCH corresponding to the second SRS resource set, wherein the index of the first SRS resource set is less than the index of the second SRS resource set; or, the first PHR included in the second information is the PHR corresponding to the first PUSCH, and the second PHR included in the second information is the PHR corresponding to the second PUSCH.

[0107] For example, for the case where the reporting method of the PHR corresponding to at least one PUSCH is joint reporting (the PUSCHs sent by different Panels are joint PHR reports), if only part of the different PUSCHs corresponding to different panels / TCI states / CORESETPoolIndex / SRS resource sets are actual transmissions (actual transmissions) in time slot n, and the rest are virtual transmissions (virtual transmissions), at this time, the PHR corresponding to each PUSCH (actual PHR+virtual PHR) can be reported simultaneously through the second information, or only the PHR corresponding to the PUSCH with actual transmission (actual transmission) (actual PHR) can be reported. Optionally, when the second information reports the PHR corresponding to each PUSCH at the same time, the second information includes the PHR corresponding to the first PUSCH and the PHR corresponding to the second PUSCH, wherein the first PUSCH transmission is actual transmission (actual transmission), the second PUSCH transmission is virtual transmission (virtual transmission), and the PHR corresponding to the first PUSCH is the actual PHR, including PH and P Cmax , the PHR corresponding to the second PUSCH is a virtual PHR, including PH and P CmaxOr only includes PH. When the second information only reports the PHR corresponding to the PUSCH of the actual transmission (actual transmission), the second information only includes the PHR corresponding to the first PUSCH, wherein the first PUSCH transmission is the actual transmission (actual transmission), and the PHR corresponding to the first PUSCH is the actual PHR, including PH and P Cmax It is further necessary to define the correspondence between the reported PHR and PUSCH, as shown below:

[0108] Option 1: The first PHR included in the second information corresponds to the PUSCH transmission associated with CORESETPoolIndex#0, and the second PHR included in the second information corresponds to the PUSCH transmission associated with CORESETPoolIndex#1;

[0109] Option 2: The first PHR included in the second information corresponds to a PUSCH transmission associated with a smaller SRS resource set Index, and the second PHR included in the second information corresponds to a PUSCH transmission associated with a larger SRS resource set Index;

[0110] Option 3: The first PHR included in the second information corresponds to PUSCH transmission associated with the actual PUSCH, and the second PHR included in the second information corresponds to PUSCH transmission associated with the virtual PUSCH.

[0111] In summary, when the reporting method is joint reporting and the first PUSCH transmission in multiple PUSCHs is actual transmission (actual transmission), and the second PUSCH transmission is virtual transmission (virtual transmission), the PHR corresponding to the first PUSCH of actual transmission (actual transmission) and the PHR corresponding to the second PUSCH of virtual transmission (virtual transmission) (actual PHR+virtual PHR) can be reported simultaneously through the second information, or only the PHR corresponding to the first PUSCH of actual transmission (actual transmission) (actual PHR) is reported, thereby improving the uplink transmission throughput and transmission reliability.

[0112] In some embodiments, in response to the reporting mode of the PHR corresponding to at least one PUSCH being jointly reported, each PUSCH in the multiple PUSCHs is not sent in a time slot overlapping with time slot n, wherein time slot n is the first time slot of the PUSCH carrying the second information, and time slot n is used as the time slot for reporting the PHR. The second information may include the PHR corresponding to each PUSCH, each PHR is a virtual PHR, and each PHR includes a power headroom PH, or each PHR includes a PH and a maximum transmit power P on the component carrier where it is located. Cmax , where the PHR is determined based on the corresponding reference PUSCH.

[0113] In some embodiments, in the case where the second information includes a PHR corresponding to each PUSCH, and each PHR is a virtual PHR, since the second information includes a PHR corresponding to each PUSCH, it is necessary to indicate the correspondence between the PHR and the PUSCH in the second information to determine which PUSCH each PHR belongs to. Optionally, the first PHR included in the second information is the PHR of the PUSCH corresponding to the first TCI state, and the second PHR included in the second information is the PHR of the PUSCH corresponding to the second TCI state; or, the first PHR included in the second information is the PHR of the PUSCH corresponding to the first CORESETPoolIndex, and the second PHR included in the second information is the PHR of the PUSCH corresponding to the second CORESETPoolIndex; or, the first PHR included in the second information is the PHR of the PUSCH corresponding to the first SRS resource set, and the second PHR included in the second information is the PHR of the PUSCH corresponding to the second SRS resource set, wherein the index of the first SRS resource set is less than the index of the second SRS resource set.

[0114] In some embodiments, in response to the reporting mode of the PHR corresponding to at least one PUSCH being a joint report, each PUSCH in the multiple PUSCHs is not sent in a time slot overlapping with time slot n, wherein time slot n is the first time slot of the PUSCH carrying the second information, and time slot n is used as the time slot for reporting the PHR, the second information may include a PHR, the PHR is a virtual PHR, the PHR includes a power headroom PH, or the PHR includes the PH and the maximum transmit power P on the component carrier. Cmax , wherein the PHR is determined based on the corresponding reference PUSCH; wherein the PHR is the PHR of the PUSCH corresponding to the first TCI state, or the PHR is the PHR of the PUSCH corresponding to the first CORESETPoolIndex, or the PHR is the PHR of the PUSCH corresponding to the SRS resource set with the smaller index in the two SRS resource sets.

[0115] That is, in the case of joint reporting, if each PUSCH in multiple PUSCHs is not sent in a time slot overlapping with time slot n, it means that each PUSCH transmission in the multiple PUSCHs is a virtual transmission (virtual transmission). At this time, when the terminal reports the second information to the network device by sending a PHR MAC CE, the second information may include a PHR corresponding to each PUSCH, each PHR is a virtual PHR, and each PHR includes a power margin PH, or each PHR includes a power margin PH and a maximum transmit power P on the component carrier. Cmax , and each PHR is determined based on the corresponding reference PUSCH. In addition, since the second information includes the PHR corresponding to each PUSCH, the correspondence between the PHR and the PUSCH needs to be indicated in the second information. Alternatively, the second information may include a PHR, which is a virtual PHR and includes the power headroom PH, or includes the power headroom PH and the maximum transmit power P on the component carrier. Cmax , and this PHR is determined based on the corresponding reference PUSCH. Optionally, this PHR can be the PHR of the PUSCH corresponding to the first TCI state, or this PHR can be the PHR of the PUSCH corresponding to the first CORESETPoolIndex, or this PHR can be the PHR of the PUSCH corresponding to the SRS resource set with the smaller index in the two SRS resource sets.

[0116] It should be noted that, for the case where each of the above-mentioned multiple PUSCHs is not transmitted in the time slot overlapping with time slot n, the present disclosure does not limit whether the second PUSCH among the multiple PUSCHs is actually transmitted in other time slots.

[0117] For example, for the case where the reporting method of the PHR corresponding to at least one PUSCH is joint reporting (the PUSCHs sent by different Panels are joint PHR reports), if the different PUSCHs corresponding to different panels / TCI states / CORESETPoolIndex / SRS resource sets have no actual PUSCH transmission in time slot n, then the PHR corresponding to each PUSCH can be reported simultaneously through the second information (virtual PHR+virtual PHR), or only one PHR (virtual PHR) can be reported. Optionally, when the second information reports the PHR corresponding to each PUSCH at the same time, the second information includes the PHR corresponding to each PUSCH, each PHR is a virtual PHR, each PHR includes the power headroom PH, or each PHR includes the PH and PHR. Cmax, and each PHR is determined based on the corresponding reference PUSCH. It is further necessary to define the correspondence between the reported PHR and PUSCH, as shown below:

[0118] Option 1: The first PHR included in the second information corresponds to the PUSCH transmission associated with CORESETPoolIndex#0, and the second PHR included in the second information corresponds to the PUSCH transmission associated with CORESETPoolIndex#1;

[0119] Option 2: The first PHR included in the second information corresponds to a PUSCH transmission associated with a smaller SRS resource set Index, and the second PHR included in the second information corresponds to a PUSCH transmission associated with a larger SRS resource set Index.

[0120] When the second information reports only one PHR, the second information includes one PHR, which is a virtual PHR including PH, or including PH and PHR. Cmax , and this PHR is determined based on the corresponding reference PUSCH, and this PHR can be the PHR of the PUSCH corresponding to the first TCI state, or this PHR can be the PHR of the PUSCH corresponding to the first CORESETPoolIndex, or this PHR can be the PHR of the PUSCH corresponding to the SRS resource set with the smaller index in the two SRS resource sets.

[0121] In summary, when the reporting method is joint reporting and each PUSCH transmission in multiple PUSCHs is virtual transmission (virtual transmission), the PHR (virtual PHR+virtual PHR) corresponding to the PUSCH of each virtual transmission (virtual transmission) in multiple PUSCHs can be reported simultaneously through the second information, or only the PHR (virtual PHR) corresponding to the PUSCH of one virtual transmission (virtual transmission) can be reported to improve the uplink transmission throughput and transmission reliability.

[0122] In some embodiments of the present disclosure, the terminal may further send fourth information to the network device, where the fourth information is used to indicate whether the terminal has the capability to support PHR enhanced calculation. Thus, the network device may be accurately informed of whether the terminal has the capability to support PHR enhanced calculation.

[0123] In some embodiments of the present disclosure, the network device may receive the fourth information. For example, if the network device receives the fourth information, it indicates that the terminal has the terminal capability of supporting PHR enhanced calculation.

[0124] In some embodiments of the present disclosure, the fourth information may be at least one of RRC signaling, DCI 0_1 signaling, DCI 0_2 signaling, and DCI 0_3 signaling, thereby effectively improving the flexibility of terminal capability indication.

[0125] Optionally, the PHR enhancement calculation includes: the first PUSCH among the multiple PUSCHs is actually sent in a time slot overlapping with time slot n, and the second PUSCH among the multiple PUSCHs is not sent in a time slot overlapping with time slot n, wherein time slot n is the first time slot of the PUSCH carrying the second information, and time slot n is used as the time slot for reporting the PHR; the power headroom PH in the PHR corresponding to the second PUSCH and the maximum transmit power P on the component carrier where it is located Cmax , is determined based on at least some transmission parameters of the first PUSCH and / or taking into account non-ideal maximum power reduction (MPR) parameters corresponding to the second PUSCH. Wherein, at least some transmission parameters of the first PUSCH are actually sent transmission parameters.

[0126] That is, the first PUSCH in the multiple PUSCHs is actually sent in the time slot overlapping with time slot n, and the second PUSCH in the multiple PUSCHs is not sent in the time slot overlapping with time slot n, wherein time slot n is the first time slot of the PUSCH carrying the second information, and when time slot n is used as the time slot for reporting PHR, the PH and P in the PHR corresponding to the second PUSCH are Cmax , is determined based on at least part of the transmission parameters of the first PUSCH of actual transmission (actual transmission) in multiple PUSCHs and / or the MPR non-ideal parameters corresponding to the second PUSCH of virtual transmission (virtual transmission) in multiple PUSCHs.

[0127] Optionally, the PHR enhancement calculation includes: each PUSCH in the multiple PUSCHs is not sent in a time slot overlapping with time slot n, where time slot n is the first time slot of the PUSCH carrying the second information, and time slot n is used as the time slot for reporting the PHR; the power headroom PH in the PHR corresponding to each PUSCH and the maximum transmit power P on the component carrier where it is located Cmax , is determined based on at least some transmission parameters of any one of the multiple PUSCHs and / or a non-ideal maximum power fallback (MPR) parameter corresponding to the PUSCH. At least some transmission parameters of any one of the multiple PUSCHs are reference values, not actual transmission parameters.

[0128] That is, when each of the multiple PUSCHs is not transmitted in a time slot overlapping with time slot n, where time slot n is the first time slot of the PUSCH carrying the second information and time slot n is used as the time slot for reporting PHR, the PH and P in the PHR corresponding to each PUSCH are Cmax , is determined based on at least some transmission parameters of any one of the multiple PUSCHs and / or taking into account a non-ideal MPR parameter corresponding to any of the aforementioned PUSCHs. In this case, since each PUSCH transmission in the multiple PUSCHs is a virtual transmission, at least some transmission parameters of any one of the multiple PUSCHs are reference values ​​rather than actually transmitted transmission parameters.

[0129] Therefore, the calculation accuracy of PHR can be effectively improved, the network device can be supported to obtain accurate PHR, the effect of PHR reporting can be improved, and the network device can be supported to obtain more meaningful PHR information.

[0130] Step S3104: The network device receives the second information sent by the terminal.

[0131] In some embodiments, the network device may receive the second information sent by the terminal, and for example, obtain the PHRs corresponding to different PUSCH transmissions carried in the MAC CE in the second information.

[0132] The uplink communication method involved in the embodiments of the present disclosure may include at least one of steps S3101 to S3104. For example, in some embodiments, steps S3101 and S3102 can be implemented as separate embodiments, and steps S3103 and S3104 can also be implemented as separate embodiments, that is, after the network device sends the first information, the terminal can use these configuration information according to the configuration in the first information in subsequent measurement reports until the network device sends new first information again to update the configuration of the PUSCH sending PHR mode. For another example, in some embodiments, step S3101 can be implemented as an independent embodiment, step S3102 can be implemented as an independent embodiment, and so on, but is not limited thereto. Steps S3101+S3102 can be implemented as independent embodiments, and steps S3101+S3102+S3103 can be implemented as independent embodiments, but are not limited thereto.

[0133] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0134] Therefore, in this embodiment, the network device sends first information to the terminal, and the first information is used to configure the terminal to send a power headroom report PHR in a multi-PHR mode. The terminal receives the first information sent by the network device. The terminal sends second information to the network device, and the second information includes a PHR corresponding to at least one of multiple physical uplink shared channels PUSCH. The network device receives the second information sent by the terminal. Therefore, under the STxMP transmission scheme in which multiple antenna panels transmit simultaneously, by giving the PHR reporting method under different PUSCH transmission conditions and defining the correspondence between PHR and PUSCH, the uplink transmission throughput and transmission reliability can be effectively improved. At the same time, the introduction of a PHR enhanced calculation scheme can enable the network device to obtain more accurate PHR information and improve the effect of PHR reporting.

[0202] The following is an exemplary introduction to the above method.

[0203] Optional embodiment:

[0204] The embodiment of the present disclosure is used to solve the problem of enhanced PHR reporting when the PUSCH channel is configured with STxMP transmission based on M-DCI. The specific method is as follows:

[0205] When PUSCH is transmitted based on M-DCI STxMP and the network configures multiple PHR modes (such as twoPHRMode) through high-layer signaling, different PUSCH transmissions (supporting scheduled DG PUSCH transmission and supporting unscheduled CG PUSCH transmission) need to be associated with different SRS resource sets / CORESETPoolIndex. The "separate" or "joint" PHR reporting mode is configured through pre-defined or high-layer signaling. The PHR MAC-CE reporting is defined as follows:

[0206] PHR trigger mode:

[0207] Per panel triggers Type 1 PHR reporting;

[0208] Per UE triggers Type 1 PHR reporting.

[0209] In some embodiments, for the case where PUSCHs sent by different panels are independent PHR reports, the PHR report corresponding to each PUSCH is the same as the existing STRP;

[0210] In some embodiments, when PUSCHs sent by different panels are used for joint PHR reporting, the following different situations need to be considered:

[0211] Case 1: Different PUSCHs corresponding to different panel / TCI state / SRS resource sets overlap with the first time slot of the PUSCH carrying MAC-CE, that is, time slot n, and there is overlapping transmission in the time domain and both are actual transmissions. It is necessary to report the PHRs corresponding to different PUSCHs at the same time. Each PHR includes {PH, P Cmax}, for example, Per panel reports P Cmax，k and PH, k = {0, 1}, k is the Pcmax corresponding to different TCI states;

[0212] It is further necessary to define the correspondence between the reported PHR and PUSCH:

[0213] Option 1: The first PHR corresponds to the PUSCH transmission associated with CORESETPoolIndex#0, and the second PHR corresponds to the PUSCH transmission associated with CORESETPoolIndex#1;

[0214] Option 2: The first PHR corresponds to the PUSCH transmission with a smaller associated SRS resource set Index, and the second PHR corresponds to the PUSCH transmission with a larger associated SRS resource set Index.

[0215] Case 2: For different PUSCHs with different panels / TCI states / SRS resource sets, only one of them is actually transmitted in time slot n, corresponding to STRP transmission:

[0216] Alt.2-1: Simultaneously report different types of PHR {PH, P Cmax}, actual+virtual;

[0217] It is further necessary to define the correspondence between the reported PHR and PUSCH:

[0218] Option 1: The first PHR included in the second information corresponds to the PUSCH transmission associated with CORESETPoolIndex#0, and the second PHR included in the second information corresponds to the PUSCH transmission associated with CORESETPoolIndex#1;

[0219] Option 2: The first PHR included in the second information corresponds to a PUSCH transmission associated with a smaller SRS resource set Index, and the second PHR included in the second information corresponds to a PUSCH transmission associated with a larger SRS resource set Index;

[0220] Option 3: The first PHR included in the second information corresponds to PUSCH transmission associated with the actual PUSCH, and the second PHR included in the second information corresponds to PUSCH transmission associated with the virtual PUSCH.

[0221] Alt.2-2: Only the PHR corresponding to the actual PUSCH is reported; the corresponding relationship is: PHR corresponds to the PUSCH transmission associated with the actual PUSCH.

[0222] Case 3: There is no actual PUSCH transmission in timeslot n for different PUSCHs corresponding to different panels / TCI states / SRS resource sets:

[0223] Alt.3-1: Simultaneously report PHR {PH, P Cmax}, virtual+virtual; the corresponding relationship reported is the same as Case 1;

[0224] Alt.3-2: Only the virtual PHR of the PUSCH corresponding to the first CoresetPoolIndex is reported, and the PHR corresponding to the second PUSCH is not reported; the reported corresponding relationship is predefined.

[0225] Alt.3-3: Only the virtual PHR of the PUSCH corresponding to the smaller SRS resource set index is reported, and the PHR corresponding to the second PUSCH is not reported;

[0226] Alt.3-4: None of them are reported.

[0227] Optionally, the disclosed embodiments also introduce new UE capabilities. When calculating virtual PHR, the terminal reports whether it supports enhanced virtual PHR calculation. If supported, the specific calculation method for virtual PHR can be predefined or configured by the network through RRC signaling, {ideal, non-ideal}, where ideal corresponds to the Pcmax / PH calculation method in the existing protocol, and non-ideal corresponds to the application considering actual transmission parameters and / or non-ideal MPR factors; the enhanced cases include:

[0228] That is, in STRP transmission (in STxMP configuration, only one panel has PUSCH transmission, so it is equivalent to STRP transmission), the actual PUSCH / reference PUSCH related transmission parameters corresponding to the panel and the MPR sent by the panel are used for P Cmax , pH calculation;

[0229] In the absence of transmission, the same reference PUSCH-related transmission parameters and MPR are used for Pcmax and PH calculations; for example, the first reference PUSCH configuration is used by default.

[0230] Optionally, the embodiment of the present disclosure further designs MAC CE:

[0231] Case 1: For the reporting mode of reporting two PHRs, pre-defined or configured through high-layer signaling is adopted (if the terminal capability supports it, the PHR is reported with reference to the PUSCH configuration), the PHR MAC-CE has a fixed byte size, and the specific design is similar to S-DCI;

[0232] Case 2: For the reporting method of only reporting the actual transmission PHR, it is predefined or configured through high-layer signaling (if the terminal capability supports it, the PHR is not reported for the reference PUSCH configuration). The specific method is:

[0233] 1) A fixed byte size design can be used, and the same MAC-CE as in Case 1 can be used. The advantage is that MPE can still support per-panel reporting.

[0234] 2) If the virtual PHR's Pcmax or PHR is not reported via RRC signaling, the PHR MAC-CE only includes the PHR report corresponding to the actual PUSCH. This has the advantage of saving signaling overhead, but the disadvantage is that it does not support per-panel MPE reporting.

[0235] 3) A new indication field is added through MAC-CE for indication.

[0236] Applicable to both single-input and multi-input PHR reporting

[0237] The single-input MAC-CE design is shown in Figures 7A-7D. Figure 7A shows a schematic diagram of an independent indication method in one embodiment of the present disclosure.
