The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0109] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0110] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0111] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0112] The embodiments disclosed herein 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), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a 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, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0113] A transmit-receive point (TRP) is an antenna array consisting of one or more antenna elements. Terminals can access a network composed of multiple TRPs (multi-TRPs) to enhance coverage, improve reliability, and increase data transmission rates.

[0114] Multiple TRPs can include macro cells, micro cells, pico cells, femtocells, remote radio heads, relay nodes, etc.

[0115] Figure 2 is a schematic diagram of a communication scenario provided according to an embodiment of the present disclosure. As shown in Figure 2, a terminal can access multiple TRPs, such as TRP1 and TRP2.

[0116] In some embodiments, in a multi-TRP accessed by a terminal, the number of TRPs used for uplink transmission can be greater than the number of TRPs used for downlink transmission. For example, TRP1 can be used for both uplink and downlink transmission of the terminal, and TRP2 can be used for uplink transmission of the terminal. This situation can be referred to as asymmetric uplink / downlink.

[0117] For TRP2, which has no downlink transmission, the downlink transmission of TRP1 can be configured for uplink transmission in TRP2. For example, the downlink path loss reference for the downlink transmission of TRP1 can be configured for the corresponding uplink transmission of TRP2.

[0118] Since the transmission distance between the terminal and different TRPs varies, the uplink path loss between the terminal and TRP2 can be determined by adjusting the downlink path loss between the terminal and TRP1 using an offset. For example, Ploss_TRP2 = Ploss_TRP1 + offset value, where Ploss_TRP2 is the uplink path loss between the terminal and TRP2, and Ploss_TRP1 is the downlink path loss between the terminal and TRP1. The offset value can be positive, negative, or equal to 0.

[0119] In some embodiments, the offset value can be sent to the terminal by the base station. For example, the offset value can be sent to the terminal via a radio resource control (RRC) message. Alternatively, the offset value can be sent to the terminal via a media access control-control element (MAC CE). Or, the offset value can be sent to the terminal via downlink control information (DCI). It is understood that static configuration of the offset value can be achieved via RRC messages, while dynamic updates of the offset value can be achieved via MAC CE or DCI.

[0120] In communication systems, terminals can report their power usage to base stations or other control nodes. This process is known as power reporting. Power reporting helps to better manage the power usage of terminals, ensuring communication quality and efficiency.

[0121] In some embodiments, power reporting may include a power headroom report (PHR). Power headroom represents the power remaining after the terminal completes the current transmission. Therefore, power headroom can be equal to the difference between the terminal's maximum transmission power and the channel power. It should be noted that this difference can be positive, negative, or equal to 0. In one example, a positive difference indicates that the terminal can transmit more data at its maximum transmission power. In another example, a negative difference indicates that the terminal's transmission power exceeds its maximum transmission power.

[0122] In some embodiments, power headroom reporting can be achieved via MAC CE. For example, a terminal can send a MAC CE to a base station, carrying the power headroom information.

[0123] In some embodiments, the triggering conditions for power margin reporting may include at least one of the following:

[0124] - For the path loss reference of the active cell, the change in path loss measured by the terminal exceeds the threshold configured by the network.

[0125] - Periodic PHR reporting timer timeout (i.e., the terminal triggers PHR at fixed time intervals);

[0126] -PHR reporting function reconfigured;

[0127] - Secondary cell (SCell) activation;

[0128] - Activation of secondary cell group (SCell group, SCG);

[0129] - Add primary and secondary cells (PSCell);

[0130] - The power back-off value transmitted by the terminal uplink exceeds the threshold configured by the network;

[0131] - The active bandwidth part (BWP) transitions from a dormant state to a non-dormant state;

[0132] - If dpc-Reporting-FR1 is configured, ΔP will return to the terminal's power level in the event of duty cycle overrun or after duty cycle overrun. PowerClass or ΔP PowerClass,CA or ΔP PowerClass,EN-DC or ΔP PowerClass,NR-DC The report was triggered;

[0133] - The measured P-MPR (maximum power reduction) is greater than or equal to the threshold;

[0134] - The measured P-MPR change value is greater than or equal to the network configuration threshold.

[0135] In some embodiments, the terminal may need to initiate a random access procedure at multiple TRPs used for uplink transmission, and these TRPs may correspond to the same downlink path loss reference.

[0136] Therefore, how to achieve power margin reporting is an urgent problem to be solved when the terminal transmits uplink data through multiple TRPs.

[0137] Figure 3 is an interactive schematic diagram of the communication method provided according to an embodiment of the present disclosure. The communication method involved in this embodiment can be applied to a communication system 100. As shown in Figure 3, the communication method of this embodiment includes steps S301 to S305.

[0138] In some embodiments, communication between terminal 101 and network device 102 can be achieved through multiple TRPs. In some embodiments, terminal 101 can access multiple TRPs and perform uplink and downlink transmissions with network device 102 through these TRPs.

[0139] In some embodiments, the path loss reference may be a path loss reference used for downlink transmission between terminal 101 and the first TRP. In one example, the path loss reference may be a downlink path loss reference. In some embodiments, the path loss reference may be used for uplink transmission between terminal 101 and the second TRP. In some embodiments, uplink and downlink transmissions may occur between terminal 101 and the first TRP, or only downlink transmissions may occur. In some embodiments, uplink and downlink transmissions may occur between terminal 101 and the second TRP, or only uplink transmissions may occur. In some embodiments, the number of first TRPs may be one or more. In some embodiments, the number of second TRPs may be one or more.

[0140] In some embodiments, terminal 101 can access two TRPs, namely TRP1 and TRP2. The first TRP includes TRP1. The second TRP includes TRP2. TRP1 can, for example, implement uplink and downlink transmission of terminal 101. TRP2 can, for example, implement uplink transmission of terminal 101.

[0141] In some embodiments, terminal 101 can access three TRPs, namely TRP1, TRP2, and TRP3. The first TRP includes TRP1. The second TRP includes TRP2 and TRP3. TRP1, for example, can implement uplink and downlink transmissions of terminal 101. TRP2, for example, can implement uplink and downlink transmissions of terminal 101. TRP3, for example, can implement uplink transmissions of terminal 101.

[0142] In step S301, network device 102 sends first information to terminal 101.

[0143] In some embodiments, network device 102 may send first information. In some embodiments, the first information may be sent by network device 102, but is not limited thereto, and may also be sent by other entities.

[0144] In some embodiments, terminal 101 may receive first information. In some embodiments, the first information may be received by terminal 101, but is not limited thereto, and may also be received by other entities.

[0145] In some embodiments, the first information may be used to configure the reporting of power margin associated with at least one beam.

[0146] In some embodiments, the first information is information related to at least one beam or spatial relationship.

[0147] In some embodiments, at least one beam may include a beam associated with at least a portion of the multiple TRPs accessed by terminal 101. In one example, the number of at least one beam may be equal to 1, in which case the beam may be a beam associated with one of the multiple TRPs accessed by terminal 101. For example, the beam may be a beam of one of TRPs TRP1, TRP2, and TRP3. In one example, the number of at least one beam may be greater than 1, in which case the beam may be a beam associated with two or more of the multiple TRPs accessed by terminal 101. For example, the beam may include beams of TRP2 and TRP3.

[0148] In some embodiments, at least one beam can also be understood as at least one spatial relationship. In a communication system, from a beamforming perspective, multiple reference signals can have the same or different spatial relationships. If multiple reference signals have the same spatial relationship, then these reference signals can be considered to be transmitted by the same beam from the same geographical location.

[0149] In some embodiments, spatial relationships may include quasi-co-location (QCL). Quasi-co-location describes the relationship between two antenna ports. In some embodiments, the two ports may be considered quasi-co-located if the large-scale properties of the channel experienced by a symbol transmission on one port can be determined from the channel experienced by a symbol transmission on the other port. In other words, the two ports may have the same spatial relationship. In some embodiments, large-scale properties may include at least one of the following: Doppler shift, Doppler spread, average delay, delay spread, and spatial rx parameter.

[0150] It should be noted that the embodiments disclosed herein are illustrated using "beam" as an example. In some embodiments, "beam" may also be replaced by "spatial relationship" or other concepts, and the comparison of the embodiments disclosed herein is not specifically limited.

[0151] In some embodiments, at least one beam may include a first beam.

[0152] In some embodiments, at least one beam may include a plurality of second beams. For example, the plurality of second beams may include beam 1, beam 2, and beam 3.

[0153] In some embodiments, the first information may include at least one of the following: beam information, path loss information, and threshold information.

[0154] In some embodiments, beam information may indicate a reference signal for measurement reporting of at least one beam. In some embodiments, the reference signal indicated by the beam information may be used to perform measurements on at least one beam.

[0155] In some embodiments, beam information may include at least one of the following: identification information of transmission configuration indicator (TCI) state, identification information of synchronization signal and physical broadcast channel block (SSB), identification information of channel state information-reference signal (CSI-RS), and identification information of sounding reference signal (SRS).

[0156] In some embodiments, the identification information for the TCI status may include a TCI status identifier. For example, the TCI status identifier may be carried in the tci-StateId field of the RRC message. The tci-StateId field can be used to indicate the ID value of the TCI status.

[0157] In some embodiments, the identification information of the TCI state can be used to indicate beam and / or spatial relationships. For example, the identification information of the TCI state can be used to determine the corresponding beam. For example, the identification information of the TCI state can be used to determine the corresponding spatial relationship. It is understood that the beam and / or spatial relationship indicated by the identification information of the TCI state can be at least one beam and / or spatial relationship related to the first information.

[0158] In some embodiments, the reference signal may include at least one of the following: SSB, CSI-RS, and SRS.

[0159] In some embodiments, the reference signal may include an SSB, and the beam information may include SSB identification information. In some embodiments, the SSB identification information may include an SSB identifier. In some embodiments, the SSB identification information may include an SSB index. For example, the SSB identification information may be carried in the ssb field of the RRC message. The ssb field may be used to indicate the SSB index value. For example, when the maximum number of SSBs is 4, the SSB index value may be 0, 1, 2, or 3.

[0160] In some embodiments, the reference signal may include CSI-RS, and the beam information may include CSI-RS identification information. In some embodiments, the CSI-RS identification information may include a CSI-RS identifier. For example, the CSI-RS identification information may include a CSI-RS resource identifier. In some embodiments, the CSI-RS identification information may be carried in the csi-RS field of the RRC message. The csi-RS field may be used to indicate the CSI-RS resource identifier (CSI-RS-ResourceId).

[0161] In some embodiments, the reference signal may include the SRS, and the beam information may include the identification information of the SRS. In some embodiments, the identification information of the SRS may include an SRS identifier. For example, the identification information of the SRS may include an SRS resource identifier. In some embodiments, the identification information of the SRS may be carried in the srs-ResourceId field of the RRC message. The srs-ResourceId field can be used to indicate the SRS resource identifier (SRS-ResourceId).

[0162] In some embodiments, path loss information can be used to determine at least one beam-related path loss. In some embodiments, path loss information can be used to configure the determination of at least one beam-related path loss.

[0163] In some embodiments, path loss information may include at least one of the following: identification information of the path loss reference signal, information of the cell corresponding to the path loss reference signal, and path loss offset information.

[0164] In some embodiments, identification information of the path loss reference signal can be used to identify the path loss reference signal. The path loss reference can be determined based on this path loss reference signal.

[0165] In some embodiments, the path loss reference can be a path loss reference used for downlink transmission between terminal 101 and TRP1. For example, network device 102 can send the path loss reference to terminal 101 via TRP1. In some embodiments, the path loss reference can be used for uplink transmission between terminal 101 and TRP2 and / or TRP2. In some embodiments, the path loss reference can be a path loss reference signal. In other words, the path loss reference can be a signal used as a reference when determining the path loss for one or more paths.

[0166] In some embodiments, path loss references may be carried in RRC messages. In some embodiments, network device 102 may send an RRC message to terminal 101, which may include path loss references. In one example, the identification information of the path loss reference signal may be indicated by the PathlossReferenceRS information element in the RRC message. The PathlossReferenceRS information element may include a pathlossReferenceRS-Id field and a referenceSignal field. The pathlossReferenceRS-Id field may indicate the identifier of the path loss reference signal. The referenceSignal field may be used to indicate the type of reference signal used by the path loss reference signal. This reference signal may include, for example, CSI-RS, SSB, etc. This reference signal is used for path loss estimation for PUSCH, PUCCH, SRS, etc.

[0167] In some embodiments, the information of the cell corresponding to the path loss reference signal may include at least one of the following: cell identifier, cell group identifier, and BWP identifier.

[0168] In some embodiments, the path loss reference signal may correspond to at least one cell. For example, at least one beam associated with the path loss reference signal may belong to at least one cell. In some embodiments, the information of the cell corresponding to the path loss reference signal may include the identifier of the at least one cell. For example, the information of the cell corresponding to the path loss reference signal may include the identifier of each cell.

[0169] In some embodiments, the cell identifier may include a physical cell identifier (PCI). In some embodiments, the cell identifier may include a serving cell identifier.

[0170] In some embodiments, the path loss reference signal may correspond to at least one cell group. This cell group may consist of one or more cells. For example, at least one beam associated with the path loss reference signal may belong to at least one cell group. In some embodiments, the information of the cell corresponding to the path loss reference signal may include the identifier of the at least one cell group. For example, the information of the cell corresponding to the path loss reference signal may include the identifier of each cell group.

[0171] In some embodiments, a cell group may include at least one of the following: a master cell group (MCG) and a secondary cell group (SCG). In one example, the identifier of a cell group may include the identifier of the master cell group. In another example, the identifier of a cell group may include the identifier of the secondary cell group.

[0172] It is understood that, for the case of cell groups, the information of the cell corresponding to the path loss reference signal may include only the identifier of the cell group, or it may include the identifier of the cell group and the identifier of each cell in the cell group. This disclosure does not specifically limit this.

[0173] In some embodiments, the information of the cell corresponding to the path loss reference signal may include the BWP identifier (BWP-Id).

[0174] In some embodiments, path loss offset information can be used to determine the path loss offset amount.

[0175] In some embodiments, path loss offset information may include at least one of the following: indication information for indicating whether path loss offset is used, and path loss offset value.

[0176] In some embodiments, indication information for indicating whether path loss offset is used can be used to determine whether path loss offset is employed.

[0177] In some embodiments, the indication information for indicating whether path loss offset is used can be a single bit. For example, a value of 1 indicates that path loss offset is used, and a value of 0 indicates that path loss offset is not used.

[0178] In some embodiments, the path loss offset value can be used to indicate the numerical value of the path loss offset employed. In one example, the path loss offset value can be a positive number. For example, the path loss offset value can be equal to 2dB. In another example, the path loss offset value can be a negative number. For example, the path loss offset value can be equal to -1dB.

[0179] In some embodiments, the path loss offset information may only include indication information for indicating whether path loss offset is used. For example, when path loss offset is not used, the path loss offset information may only include indication information for indicating whether path loss offset is used, and the value of this indication information can be 0. For example, when path loss offset is used, the path loss offset information may only include indication information for indicating whether path loss offset is used, and the value of this indication information can be 1. In this case, the path loss offset value may be protocol-defined or previously configured. In some embodiments, the path loss offset information may include indication information for indicating whether path loss offset is used, and the path loss offset value.

[0180] In some embodiments, threshold information can be used to determine a first threshold for triggering power margin reporting.

[0181] In some embodiments, the first threshold can be used by terminal 101 to determine whether to trigger power margin reporting. In some embodiments, the first threshold can be used as a triggering condition for power margin reporting.

[0182] In some embodiments, the first threshold may include a threshold for at least one beam.

[0183] In some embodiments, the first threshold may include a threshold for a single beam. For example, the number of at least one beam may be one, i.e., including one first beam. The first threshold may be configured for the first beam.

[0184] In some embodiments, the first threshold may include a threshold for multiple beams. For example, the number of at least one beam may be greater than one, i.e., it may include multiple second beams. The first threshold may be configured for multiple second beams. It is understood that the multiple second beams may have the same path loss reference.

[0185] In some embodiments, threshold information may be included in path loss information.

[0186] In some embodiments, the first information may be carried in at least one of the following: RRC message, MAC CE, DCI.

[0187] In some embodiments, the first information can be sent by a single signaling signal, or by multiple signaling signals simultaneously or sequentially.

[0188] In some embodiments, network device 102 may send a signaling message to terminal 101, carrying the entire content of the first information therein. In some embodiments, network device 102 may send multiple signaling messages to terminal 101, each signaling message including a portion of the first information. In some embodiments, these multiple signaling messages may be sent simultaneously or sequentially. For example, beam information and path loss information may be sent through a single signaling message. For example, beam information and path loss information may be sent through two separate signaling messages.

[0189] In some embodiments, each of the multiple signaling messages can be one of the following: RRC message, MAC CE, or DCI. For example, network device 102 can send two RRC messages to terminal 101. One RRC message can carry path loss information from the first information. The other RRC message can carry other information from the first information besides path loss information. For example, network device 102 can send one RRC message and one DCI to terminal 101. The RRC message can carry the identification information of the path loss reference signal and the information of the cell corresponding to the path loss reference signal from the first information. The DCI can carry other information from the first information.

[0190] In step S302, terminal 101 determines the path loss value.

[0191] In some embodiments, after obtaining the first information, the terminal 101 can determine the path loss value based on the first information.

[0192] In some embodiments, terminal 101 can obtain the path loss offset value from the first information. Next, terminal 101 can determine the path loss value of the first beam based on the path loss offset value of the first beam. It is understood that the path loss value determined for the first beam can be referred to as the first path loss value corresponding to the first beam.

[0193] In some embodiments, the first beam may be an uplink beam corresponding to a second TRP. Terminal 101 can obtain the downlink path loss value of the first TRP and calculate the sum of the downlink path loss value and the path loss offset value to obtain the path loss value of the first beam of the second TRP. For example, the first beam may be the beam of TRP2. Terminal 101 can determine the path loss value of the first beam using the following formula: Ploss_TRP2 = Ploss_TRP1 + offset value. Ploss_TRP1 may be the downlink path loss of TRP1. Ploss_TRP2 may be the uplink path loss of the first beam of TRP2.

[0194] In some embodiments, the downlink path loss value of the first TRP can be determined by the terminal 101 performing a measurement of the downlink reference signal for the first TRP.

[0195] In some embodiments, terminal 101 can obtain a path loss reference from the first information. Next, terminal 101 can determine the path loss value of the second beam based on the path loss reference of the second beam. It is understood that the path loss value determined for the second beam can be referred to as the third path loss value corresponding to the second beam.

[0196] In some embodiments, multiple second beams may correspond to the same path loss reference. Terminal 101 may perform measurements based on this path loss reference to obtain path loss values ​​for the multiple second beams. It is understood that one or more path loss values ​​may be obtained for the multiple second beams. In one example, a corresponding path loss value may be obtained for each second beam. In some embodiments, the path loss values ​​corresponding to different second beams may be the same or different. In one example, a single path loss value may be obtained for the multiple second beams. For example, terminal 101 may determine a single path loss value based on the multiple path loss values ​​corresponding to the multiple second beams. For example, terminal 101 may perform an average or weighted average of the multiple path loss values ​​corresponding to the multiple second beams to obtain a single path loss value.

[0197] In step S303, terminal 101 determines that the change in path loss is greater than the first threshold.

[0198] In some embodiments, after obtaining the path loss value of at least one beam, the terminal 101 can determine the amount of change in path loss; then, the terminal 101 can compare the amount of change with a first threshold to determine whether the amount of change in path loss of at least one beam is greater than the first threshold.

[0199] In some embodiments, where at least one beam includes a first beam, terminal 101 can determine the amount of change between the path loss value of the first beam and the path loss value reported in the previous power margin exercise. In some embodiments, the path loss value reported in the previous power margin exercise is the power loss value for the first beam. It is understood that the path loss value reported in the previous power margin exercise for the first beam can be referred to as the second path loss value. Therefore, the amount of change in the path loss corresponding to the first beam can be the difference between the first path loss value corresponding to the first beam and the second path loss value corresponding to the first beam.

[0200] In some embodiments, the change can be equal to the difference between the path loss value of the first beam and the path loss value reported in the previous power margin exercise. For example, the change can be equal to the path loss value of the first beam minus the path loss value reported in the previous power margin exercise. In this case, the change can be positive, negative, or equal to 0. For example, if the change is positive (i.e., greater than 0), the path loss value of the first beam is greater than the path loss value reported in the previous power margin exercise. For example, if the change is negative (i.e., less than 0), the path loss value of the first beam is less than the path loss value reported in the previous power margin exercise. For example, if the change is 0, the path loss value of the first beam is equal to the path loss value reported in the previous power margin exercise. It is understood that the change in this case can indicate the direction and magnitude of the change.

[0201] In some embodiments, the change may be equal to the absolute value of the difference between the path loss value of the first beam and the path loss value reported in the previous power margin update. In this case, the change may be greater than or equal to 0. It is understood that the change in this case may only indicate the magnitude of the change.

[0202] In some embodiments, the path loss value reported in the previous power margin report may include one of the following: the path loss value at the time of the previous power margin report; the path loss value at the time of the previous power margin report and when the terminal 101 has a new transmission; or the path loss value at the time of the previous power margin report and when the terminal 101 has a new transmission on the first beam.

[0203] Figure 4A is a schematic diagram of a scenario where a trigger power margin reporting is provided according to an embodiment of this disclosure. As shown in Figure 4A, terminal 101 performs a previous power margin reporting at time t1. At time t2, terminal 101 determines the path loss value of the first beam based on the path loss offset value. Time t1 is earlier than time t2.

[0204] Figure 4B is a schematic diagram of another scenario of triggering power headroom reporting according to an embodiment of the present disclosure. As shown in Figure 4B, terminal 101 performs a previous power headroom report at time t1. At time t1 (i.e., at the time of the previous power headroom report), terminal 101 may have a new transmission. In one example, at time t1, terminal 101 may have allocated uplink resources for transmitting data. These uplink resources may, for example, be used for a new transmission. At time t2, terminal 101 determines the path loss value of the first beam based on the path loss offset value. Time t1 is earlier than time t2.

[0205] Figure 4C is a schematic diagram of another scenario of triggering power margin reporting according to an embodiment of the present disclosure. As shown in Figure 4C, terminal 101 performs a previous power margin report at time t1. At time t1 (i.e., when the previous power margin report was performed), terminal 101 can have new transmissions on the first beam. At time t2, terminal 101 determines the path loss value of the first beam based on the path loss offset value. Time t1 is earlier than time t2.

[0206] In some embodiments, where at least one beam includes multiple second beams, terminal 101 can determine the amount of change between the path loss value of the second beam and the path loss value reported in the previous power margin exercise. In some embodiments, the path loss value reported in the previous power margin exercise is the power loss value for the second beam. It is understood that the path loss value reported in the previous power margin exercise for the second beam can be referred to as the fourth path loss value. Then, the amount of change in the path loss corresponding to the second beam can be the difference between the third path loss value corresponding to the second beam and the fourth path loss value corresponding to the second beam.

[0207] In some embodiments, the change can be equal to the difference between the path loss value of the second beam and the path loss value reported in the previous power margin exercise. For example, the change can be equal to the path loss value of the second beam minus the path loss value reported in the previous power margin exercise. In this case, the change can be positive, negative, or equal to 0. For example, if the change is positive (i.e., greater than 0), the path loss value of the second beam is greater than the path loss value reported in the previous power margin exercise. For example, if the change is negative (i.e., less than 0), the path loss value of the second beam is less than the path loss value reported in the previous power margin exercise. For example, if the change is 0, the path loss value of the second beam is equal to the path loss value reported in the previous power margin exercise. It is understood that the change in this case can indicate the direction and magnitude of the change.

[0208] In some embodiments, the change may be equal to the absolute value of the difference between the path loss value of the second beam and the path loss value reported in the previous power margin exercise. In this case, the change may be greater than or equal to 0. It is understood that the change in this case may only indicate the magnitude of the change.

[0209] In some embodiments, the change in the path loss value of a second beam compared to the path loss value reported in the previous power margin can be performed separately for each second beam. In one example, terminal 101 can determine the change based on the path loss value corresponding to each second beam and the path loss value reported in the previous power margin. For example, terminal 101 can determine the change in the path loss value of beam 1 compared to the path loss value reported in the previous power margin, the change in the path loss value of beam 2 compared to the path loss value reported in the previous power margin, and the change in the path loss value of beam 3 compared to the path loss value reported in the previous power margin.

[0210] In some embodiments, the change in the path loss value of a second beam compared to the path loss value reported in the previous power margin can be performed jointly for multiple second beams. In one example, terminal 101 can determine the change based on the same path loss value corresponding to multiple second beams and the same path loss value reported in the previous power margin for multiple second beams. For example, terminal 101 can determine the change between a path loss value jointly determined for beams 1, 2, and 3 and a path loss value jointly reported in the previous power margin for beams 1, 2, and 3. In one example, terminal 101 can determine the change based on the same path loss value corresponding to multiple second beams and the path loss value reported by each second beam in the previous power margin. For example, terminal 101 can determine the change between the path loss value of beam 1 and a path loss value reported by beams 1, 2 and 3 in the previous power margin, the change between the path loss value of beam 2 and a path loss value reported by beams 1, 2 and 3 in the previous power margin, and the change between the path loss value of beam 3 and a path loss value reported by beams 1, 2 and 3 in the previous power margin.

[0211] Figure 5A is a schematic diagram of a trigger power margin reporting scenario provided according to an embodiment of the present disclosure. As shown in Figure 5A, terminal 101 performs a previous power margin reporting at time t1. At time t2, terminal 101 determines the path loss value of the second beam based on the path loss reference. Time t1 is earlier than time t2.

[0212] Figure 5B is a schematic diagram of another scenario of triggering power headroom reporting according to an embodiment of the present disclosure. As shown in Figure 5B, terminal 101 performs a previous power headroom report at time t1. At time t1 (i.e., at the time of the previous power headroom report), terminal 101 may have a new transmission. In one example, at time t1, terminal 101 may have allocated uplink resources for transmitting data. These uplink resources may, for example, be used for a new transmission. At time t2, terminal 101 determines the path loss value of the first beam based on a path loss reference. Time t1 is earlier than time t2.

[0213] Figure 5C is a schematic diagram of another scenario of triggering power headroom reporting according to an embodiment of the present disclosure. As shown in Figure 5C, terminal 101 performs a previous power headroom report at time t1. At time t1 (i.e., during the previous power headroom report), terminal 101 can have new transmissions on any of the multiple second beams. At time t2, terminal 101 determines the path loss value of the second beam based on a path loss reference. Time t1 is earlier than time t2.

[0214] Figure 5D is a schematic diagram of another case of triggering power margin reporting according to an embodiment of the present disclosure. As shown in Figure 5D, terminal 101 performs a previous power margin report at time t1. At time t1 (i.e., when the previous power margin report was performed), terminal 101 can have new transmissions on multiple second beams. At time t2, terminal 101 determines the path loss value of the second beam based on a path loss reference. Time t1 is earlier than time t2.

[0215] In some embodiments, terminal 101 may compare the obtained change in path loss with a first threshold.

[0216] In some embodiments, the change in path loss can be positive, negative, or equal to 0. In one example, if the change is negative and less than a negative threshold, terminal 101 can determine that the change in path loss is greater than or equal to a first threshold. In one example, if the change is positive and greater than a positive threshold, terminal 101 can determine that the change in path loss is greater than or equal to a first threshold.

[0217] In some embodiments, the change in path loss can be a positive number or equal to 0. In one example, if the change is greater than a first threshold, terminal 101 can determine that the change in path loss is greater than or equal to the first threshold.

[0218] In some embodiments, for the case of the first beam, terminal 101 can compare the change in path loss of the first beam with a first threshold configured for the first beam. In some embodiments, the first threshold for the first beam may be obtained from first information.

[0219] In some embodiments, for the case of multiple second beams, terminal 101 can compare the change in path loss of the second beam with a first threshold configured for the second beam. In some embodiments, the first threshold for the second beam may be obtained from first information.

[0220] In some embodiments, network device 102 can configure a first threshold for different beams. The first thresholds for different beams can be the same or different. In some embodiments, the first thresholds for multiple second beams can be different or the same.

[0221] In some embodiments, network device 102 can configure the same first threshold for multiple second beams. In one example, multiple second beams having the same path loss reference can form a beam group. This beam group can be configured with a first threshold. In this case, the first threshold can be applied to all second beams in the beam group.

[0222] In some embodiments, the MAC entity corresponding to the first information and the MAC entity corresponding to the power margin reporting can be the same. For example, both the MAC entity corresponding to the first information and the MAC entity corresponding to the power margin reporting can be terminal 101.

[0223] In step S304, terminal 101 triggers a power margin report.

[0224] In some embodiments, terminal 101 may trigger power margin reporting if a first condition is met. In some embodiments, terminal 101 may trigger power margin reporting associated with at least one beam if the first condition is met.

[0225] In some embodiments, the first condition can be used to determine whether to trigger power margin reporting. In some embodiments, the first condition can be a triggering condition for power margin reporting.

[0226] In some embodiments, the first condition may include at least one of the following: the change in path loss associated with at least one beam is greater than or equal to a first threshold, or the terminal 101 receives a path loss offset value corresponding to at least one beam.

[0227] In some embodiments, the first condition may be related to received path loss information. In one example, the path loss information in the first information may include a path loss offset value. In this case, if terminal 101 determines that the first information is used to configure or reconfigure the path loss offset value, terminal 101 may trigger a power headroom report. In one example, the path loss in the first information may include threshold information. In this case, if the change in path loss associated with at least one beam is greater than or equal to a first threshold, terminal 101 may trigger a power headroom report.

[0228] In some embodiments, if the change in path loss of at least one beam is determined to be greater than or equal to a first threshold, terminal 101 may trigger a power margin report. Of course, in some embodiments, if the change in path loss of at least one beam is determined to be greater than the first threshold, terminal 101 may trigger a power margin report.

[0229] In step S305, terminal 101 sends second information to network device 102.

[0230] In some embodiments, terminal 101 may send second information. In some embodiments, the second information may be sent by terminal 101, but is not limited thereto, and may also be sent by other entities.

[0231] In some embodiments, network device 102 may receive second information. In some embodiments, the second information may be received by network device 102, but is not limited thereto, and may also be received by other entities.

[0232] In some embodiments, the second information can be used to implement power margin reporting.

[0233] In some embodiments, the second information may be sent when the terminal 101 triggers a measurement margin reporting. In some embodiments, the second information may be sent when a first condition is met.

[0251] Figure 6 is an interactive schematic diagram of a communication method provided according to an embodiment of the present disclosure. This disclosure relates to a communication method. As shown in Figure 6, the method includes steps S601 to S602.

[0252] In step S601, network device 102 sends path loss information to terminal 101.

[0253] The optional implementation of step S601 can be found in the optional implementation of step S301 in Figure 3, as well as other related parts in the embodiments involved in Figure 3, which will not be repeated here.

[0254] In step S602, if the first condition is met, the terminal 101 triggers a power margin report.

[0255] The optional implementation of step S602 can be found in the optional implementation of step S304 in Figure 3, as well as other related parts in the embodiments involved in Figure 3, which will not be repeated here.

[0256] In the following, the technical solutions of the embodiments of this disclosure will be described by way of specific implementation.

[0257] In this embodiment of the disclosure, by allowing the terminal to distinguish the transmission power of different uplink TRPs (i.e., the second TRP) and the path loss of different uplink TRPs, the terminal can report the power information on the terminal side in more real time. At the same time, the terminal can also calculate more accurate power information based on the "path loss of different uplink TRPs" and report it to the network side.

[0258] In some embodiments, the terminal triggers a power margin report when specific triggering conditions are met, based on "path loss information corresponding to the beam (or spatial relationship)". The aforementioned power margin report triggering conditions include at least one of the following:

[0259] Triggering Condition 1: The terminal receives a path loss offset for a specific beam from the network side (e.g., an RRC message or MAC CE indication). The terminal calculates the path loss value for that specific beam based on the path loss offset (e.g., at time t2). The terminal compares this value with the previous path loss value for that beam (e.g., at time t1). If the change is greater than or equal to the "path loss change threshold" configured by the network, a power margin report is triggered. The "previous path loss value for that beam" can be any of the following:

[0260] - Triggering condition 1.1: The path loss value corresponding to the PHR during the last PHR transmission.

[0261] - Triggering condition 1.2: When the previous PHR was transmitted, and the MAC entity had uplink resources for the new transmission (i.e., new data transmission), the path loss value corresponding to that PHR.

[0262] - Triggering condition 1.3: The path loss value corresponding to the PHR during the last PHR transmission, and the uplink transmission of this specific beam.

[0263] Triggering Condition 2: If multiple beams correspond to the same path loss reference, the path loss value measured by the same path loss reference for these multiple beams (e.g., time t2) is compared with the previous path loss value for the same path loss reference for these multiple beams (e.g., time t1). If the change is greater than or equal to the "path loss change threshold" configured in the network, then a power margin report is triggered. The "previous path loss value for the same path loss reference for these multiple beams" can be any of the following:

[0264] - Triggering condition 2.1: The path loss value corresponding to the PHR during the last PHR transmission.

[0265] - Triggering condition 2.2: When the previous PHR was transmitted, and the MAC entity had uplink resources for the new transmission (i.e., new data transmission), the path loss value corresponding to that PHR.

[0266] - Triggering condition 2.3: When the last PHR was transmitted, and any one of the multiple beams had uplink transmission, the path loss value corresponding to the PHR.

[0267] - Triggering condition 2.4: When the previous PHR was transmitted, and all of these multiple beams had uplink transmissions, the path loss value corresponding to this PHR.

[0268] Triggering condition 3: The RRC message configures (or reconfigures) the path loss offset for a specific beam (e.g., the RRC message configures the path loss offset for the terminal's TCI-state-1 for the first time).

[0269] Step 1: The network side provides the terminal side with path loss information corresponding to the beam (or, spatial relationship (e.g., QCL (Quasi-CoLocation) relationship)).

[0270] In some embodiments, the network side configures the path loss offset (e.g., path loss offset value) of TCI-state-1 (i.e., beam identifier or spatial relationship identifier) ​​via RRC message, and then updates the path loss offset of TCI-state-1 via MAC CE.

[0271] In some embodiments, the "path loss information corresponding to the beam (or, spatial relationship (e.g., QCL (Quasi-CoLocation) relationship)" includes:

[0272] (1) Beam information, wherein the "beam information" includes at least one of the following:

[0273] -TCI status indicator;

[0274] -SSB identifier;

[0275] -CSI-RS identifier;

[0276] -SRS identifier;

[0277] (2) Road damage information, wherein the "road damage information" includes at least one of the following:

[0278] - Path loss reference signal identifier (e.g., pathlossReferenceSignal-ID)

[0279] - Cell information corresponding to the road loss reference signal, wherein the "cell information" includes at least one of the following:

[0280] - Cell identifier (e.g., physical cell identifier (e.g., PCI-1) or serving cell identifier (e.g., serving_cell_1));

[0281] - Cell group identifier (e.g., MCG or SCG);

[0282] -BWP identifier (e.g., BWP-ID);

[0283] (3) Road loss offset information, wherein the "road loss offset information" includes at least one of the following:

[0284] - Indication information on whether to use path loss offset (e.g., a 1-bit value of "0" indicates that path loss offset is not used, and a value of "1" indicates that path loss offset is used);

[0285] - Road loss offset (e.g., 2dB).

[0286] Step 2: The terminal triggers the power margin report when the specific triggering condition (i.e., the first condition) is met, based on the path loss information corresponding to the beam (or spatial relationship).

[0287] Triggering Condition 1: The terminal receives a path loss offset for a specific beam from the network side (e.g., an RRC message or MAC CE indication). The terminal calculates the path loss value for that specific beam based on the path loss offset (e.g., at time t2). The terminal compares this value with the previous path loss value for that beam (e.g., at time t1). If the change is greater than or equal to the "path loss change threshold" configured by the network, a power margin report is triggered. The "previous path loss value for that beam" can be any of the following:

[0288] - Triggering condition 1.1: The path loss value corresponding to the PHR during the last PHR transmission.

[0289] - Triggering condition 1.2: When the previous PHR was transmitted, and the MAC entity had uplink resources for the new transmission (i.e., new data transmission), the path loss value corresponding to that PHR.

[0290] - Triggering condition 1.3: The path loss value corresponding to the PHR during the last PHR transmission, and the uplink transmission of this specific beam.

[0291] Triggering Condition 2: If multiple beams correspond to the same path loss reference, the path loss value measured by the same path loss reference for these multiple beams (e.g., time t2) is compared with the previous path loss value for the same path loss reference for these multiple beams (e.g., time t1). If the change is greater than or equal to the "path loss change threshold" configured in the network, then a power margin report is triggered. The "previous path loss value for the same path loss reference for these multiple beams" can be any of the following:

[0292] - Triggering condition 2.1: The path loss value corresponding to the PHR during the last PHR transmission.

[0293] - Triggering condition 2.2: When the previous PHR was transmitted, and the MAC entity had uplink resources for the new transmission (i.e., new data transmission), the path loss value corresponding to that PHR.

[0294] - Triggering condition 2.3: When the last PHR was transmitted, and any one of the multiple beams had uplink transmission, the path loss value corresponding to the PHR.

[0295] - Triggering condition 2.4: When the previous PHR was transmitted, and all of these multiple beams had uplink transmissions, the path loss value corresponding to this PHR.

[0296] Triggering condition 3: The RRC message configures (or reconfigures) the path loss offset for a specific beam (e.g., the RRC message configures the path loss offset for the terminal's TCI-state-1 for the first time).

[0297] In some embodiments, different "path loss change threshold values" can be configured for different beams on the network side. Then, the path loss value of a specific beam of the terminal is compared with the "path loss change threshold value" of that specific beam to determine whether to trigger power margin reporting.

[0298] In some embodiments, the network side can configure a specific "path loss change threshold" for beam groups (i.e., multiple beams) with the same path loss reference. The path loss value corresponding to the beam group of the terminal is compared with the "path loss change threshold" corresponding to that beam group to determine whether to trigger power margin reporting.

[0299] In some embodiments, the MAC entity corresponding to the road loss information is the same as the MAC entity corresponding to the power margin report.

[0300] In the embodiments disclosed herein, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations in other embodiments.

For example, the processor is a hardware circuit implemented by an application-specific integrated circuit (ASIC) or a programmable logic device, such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), tensor processing unit (TPU), deep learning processing unit (DPU), etc.
