[0034] The exemplary embodiments will be described in detail herein with reference to the drawings. In the following description, unless otherwise indicated, like numbers in the different drawings represent the same or similar elements. The following exemplary embodiments are described with reference to the drawings, wherein:

[0035] The power control parameter determination method of the embodiments of the present disclosure can be applied to a wireless communication system as shown in FIG. 1. Figure 1 As shown in FIG. 1, the wireless communication system includes a network device and a terminal. The terminal is connected to the network device through a wireless resource and performs data transmission.

The terminal is connected to the network device through a wireless resource and performs data transmission.

[0036] It can be understood that the wireless communication system shown in FIG. 1 is only illustrative, and the wireless communication system can further include other network devices, such as a core network device, a wireless relay device, and a wireless backhaul device, etc., which are not shown in FIG. 1. The embodiments of the present disclosure do not limit the number of network devices and the number of terminals in the wireless communication system. Figure 1 Figure 1 It can be understood that the wireless communication system shown in FIG. 1 is only illustrative, and the wireless communication system can further include other network devices, such as a core network device, a wireless relay device, and a wireless backhaul device, etc., which are not shown in FIG. 1. The embodiments of the present disclosure do not limit the number of network devices and the number of terminals in the wireless communication system.

[0037] ​It can be further understood that the wireless communication system of the embodiments of the present disclosure is a network that provides wireless communication functions. The wireless communication system can use different communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), single carrier frequency division multiple access (SC-FDMA), carrier sense multiple access with collision avoidance (CSMA / CA), and the like. Depending on the capacity, speed, latency, and the like of different networks, the network can be divided into 2G, 3G, 4G, or future evolution networks, such as 5G networks. The 5G network can also be referred to as a new radio (NR) network. For the convenience of description, the wireless communication network in the present disclosure can be referred to as a network.

[0038] Further, the network device involved in the present disclosure can also be referred to as a wireless access network device. The wireless access network device can be a base station, an evolved node B (eNB), a home base station, an access point (AP) in a wireless fidelity (WiFi) system, a wireless relay node, a wireless backhaul node, a transmission point (TP), a transmission and reception point (TRP), and the like. It can also be a gNB in an NR system, or it can be a component or part of a device constituting a base station, and the like. It should be understood that the specific technology and specific device form of the network device are not limited in the embodiments of the present disclosure. In the present disclosure, the network device can provide communication coverage for a specific geographic area, and can communicate with terminals located in the coverage area (cell). In addition, when it is a vehicle-to-everything (V2X) communication system, the network device can also be a vehicle-mounted device.

[0039] Further, the terminal involved in the present disclosure, which can also be referred to as a terminal device, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc., is a device that provides voice and / or data connectivity to a user, such as a handheld device having wireless connection capability, a vehicle-mounted device, etc. Currently, some examples of the terminal are a mobile phone, a customer premise equipment (CPE), a pocket personal computer (PPC), a palm PC, a personal digital assistant (PDA), a notebook computer, a tablet computer, a wearable device, or a vehicle-mounted device, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device can also be a vehicle-mounted device. It should be understood that the present disclosure embodiments do not limit the specific technology and specific device form of the terminal.

[0040] The application of base station multi-TRP / panel is mainly to improve the coverage of the cell edge, provide more balanced service quality in the service area, and transmit data in different ways between multiple TRPs / panels. From the perspective of network form, network deployment in the way of a large number of distributed access points plus baseband centralized processing will be more conducive to providing balanced user experience rate, and significantly reducing the delay and signaling overhead caused by handover. By using the cooperation between multiple TRPs or panels and the transmission / reception of multiple beams from multiple angles, various shielding / blocking effects can be better overcome, the robustness of link connection can be guaranteed, and the transmission quality of URLLC service can be improved and the reliability requirement can be met.

[0041] In some embodiments of the present disclosure, the transmission of the physical downlink shared channel (PDSCH) can be enhanced based on the application of the downlink multi-TRP / PANEL multi-point cooperative transmission technology. Since data transmission includes the scheduling feedback of uplink and downlink channels, in the research of URLLC, only the enhancement of the downlink data channel cannot guarantee the service performance. Therefore, the physical downlink control channel (PDCCH) and the physical uplink control channel (PUCCH) and the data channel such as the physical uplink shared channel (PUSCH) need to be further enhanced.

[0042] The uplink PUSCH transmission is transmitted to multiple TRPs of the base station. In some embodiments of the present disclosure, the cooperative transmission in the TDM transmission mode is standardized, and different repetitions of the same information on the PUSCH are transmitted to different TRPs of the base station in different transmission occasions (TOs) in the time domain. This method has a relatively low requirement on the terminal capability and does not require the capability of simultaneously transmitting beams, and has a large transmission delay.

[0043] For the uplink, the actual channels of the PUSCH channels oriented to different TRPs can have very different spatial characteristics, and thus the QCL-D of the PUSCH channels in different transmission directions is considered to be different.

[0044] The above implementation scheme does not consider the multiple-TRP (M-TRP) scenario, and the uplink is single-TRP (S-TRP) transmission. In some embodiments of the present disclosure, the M-TRP uplink transmission in the S-DCI is enhanced, the uplink PUSCH transmission is transmitted to multiple TRPs of the base station, and the cooperative transmission in the TDM transmission mode is standardized. Different repetitions of the same information on the PUSCH are transmitted to different TRPs of the base station in different transmission occasions (TOs) in the time domain. This method has a relatively low requirement on the terminal capability, and each TO only transmits a PUSCH in a TRP direction, thus does not require the capability of simultaneously transmitting beams, and has a large transmission delay.

[0045] In some embodiments of the present disclosure, it is desired to achieve simultaneous cooperative transmission by multiple terminal panels to multiple TRPs of the base station to increase the reliability and throughput of transmission, and effectively reduce the transmission delay in the multi-TRP mode, but the terminal is required to have the capability of simultaneously transmitting multiple beams. The transmission of the PUSCH can be based on single-physical downlink control channel (PDCCH) (S-DCI) scheduling of multi-panel or multi-TRP transmission, such as Figure 2As shown. Among them, the UE communicates with the base station TPR1 through panel1, such as receiving the first precoding indication information (Transmit Precoding Matrix Indicator, TPMI) TPMI1 sent by TPR1, and sending one or more transmission layer related information to TPR1, and communicating with the base station TPR2 through panel2, such as receiving the second precoding indication information TPMI2 sent by TPR2, and sending one or more transmission layer related information to TPR2. It can also be based on different PDCCH, that is, Multiple-Downlink Control Information (M-DCI) scheduling multi-panel or multi-TRP transmission, such as Figure 3 As shown. Among them, the UE communicates with the base station TPR1 through panel1, such as receiving the first precoding indication information (Transmit Precoding Matrix Indicator, TPMI) TPMI1 sent by TPR1, and sending one or more transmission layer related information to TPR1, and communicating with the base station TPR2 through panel2, such as receiving the second precoding indication information TPMI2 sent by TPR2, and sending one or more transmission layer related information to TPR2. It can also be based on different PDCCH, that is, Multiple-Downlink Control Information (M-DCI) scheduling multi-panel or multi-TRP transmission, such as

[0046] The terminal is generally configured with multiple physical panels, and the capabilities of different panels may also be different, such as different numbers of Sounding Reference Signal (SRS) ports, and the maximum number of data transmission layers supported may also be different, such as one panel supporting a maximum of 2-layer transmission and another panel supporting a maximum of 4-layer transmission. The network scheduler will determine whether the terminal is currently suitable for multi-panel uplink simultaneous transmission, and if the terminal is currently suitable for multi-panel uplink simultaneous transmission and is scheduled, the network will directly or indirectly indicate the relevant transmission parameters, including terminal specific beam indication information, data layer number used for transmission, and Demodulation Reference Signal (DMRS) port allocation, and precoding indication information, etc.

[0047] In certain embodiments of the present disclosure, the transmission schemes supported by the S-DCI based PUSCH support include a Space Division Multiplexing (SDM) scheme and a Single Frequency Network (SFN) scheme for uplink multi-panel simultaneous transmission (STxMP). In the SDM scheme, different parts of one transport block (TB) of the PUSCH are transmitted on the same time-frequency resources by different panels on their respective DMRS ports or port combinations facing two different TRPs, and different panels or different TRPs or different TOs are associated with different TCI states, i.e., beams. In the SFN scheme, one TB of the PUSCH is transmitted on the same time-frequency resources by different panels on the same DMRS port or port combination facing two different TRPs, and different panels or different TRPs or different TOs are associated with different TCI states, i.e., beams.

[0048] In the 5G system, there are data services with different priorities, latency requirements or reliability requirements, such as URLLC services with extremely high requirements for latency and reliability, and eMBB services with relatively low requirements for latency and reliability. Generally, URLLC will be scheduled with a shorter transmission time interval, and URLLC services have burstiness and randomness, and present scattered characteristics in resource distribution, with low resource utilization. Therefore, it can be considered to multiplex with eMBB transmission to improve the utilization of resources. Unlike downlink transmission, a UE does not know whether the transmission resources of its service data overlap with the transmission of services with different priorities by other UEs when sending uplink data. In order to ensure the reliability of URLLC service transmission, an open-loop power control parameter set indication can be introduced in the scheduling of DCI to indicate the power boosting indication function for scheduling PUSCH. A new RRC parameter P0-PUSCH-Set can be introduced to indicate power control, and each SRI corresponds to an open-loop power control P0-PUSCH-Set parameter, which is indicated by the open-loop power control parameter indication field.

[0049] In uplink STxMP transmission, there is still a case where the network expects to prioritize the transmission reliability of URLLC services when different terminals send eMBB and URLLC services in the system. In the PUSCH enhancement based on M-TRP, the URLLC services sent based on M-TRP in different TRPs and eMBB services conflict in different scenarios, that is, the conflict interference received by the two TRPs at the base station end is different. If the different interferences of different TRPs in M-TRP are not distinguished, the adjustment mechanism will cause the terminal to be unable to adapt to the interference situation to send power, increase the interference to other users, and cause the problem of reducing system performance.

[0050] As Figure 4As shown, if UE1 transmits URLLC service data to TRP1 and TRP2 on the PUSCH, and UE2 transmits EMBB service data to TRP1 on the PUSCH, the conflict interference received by TRP1 and TRP2 is different, and therefore the transmission power of the terminal under different interference conditions needs to be optimized.

[0051] Currently, the terminal can use a unified TCI state to indicate a beam, and the power control parameters of the PUSCH / PUCCH / SRS are associated with the unified TCI state / upper TCI state. However, based on independent power control of each TRP, the SRI / space relationship indication is used to indicate the power control settings associated with each TRP respectively. However, when the terminal supports the unified TCI state to indicate the beam, the uplink transmission beam is indicated by the unified TCI state / upper TCI state indication instead of the SRI / space relationship indication.

[0052] Therefore, in the case that the terminal supports the unified TCI state to indicate the beam, how to more reasonably handle the conflict of different service terminals for STxMP transmission is a problem to be solved.

[0053] In view of this, the power control parameter determination method provided by the embodiments of the present disclosure receives the capability information reported by the terminal when determining that the terminal performs STxMP transmission of the PUSCH and the terminal supports Unified TCI state to indicate the beam, and configures one or more OLPC indication fields for the terminal based on the capability information, enhances the power boosting mechanism of OLPC, and can more reasonably handle the conflict of different service terminals for STxMP transmission, thereby optimizing the terminal and system performance.

[0054] Figure 5 A flowchart of a power control parameter determination method according to an exemplary embodiment is shown in FIG. 1. Figure 5 As shown, the power control parameter determination is performed by a network device, including the following steps.

[0055] In step S11, it is determined that the terminal performs STxMP transmission of the PUSCH, and the terminal supports Unified TCI state to indicate the beam, and one or more OLPC indication fields are configured for the terminal.

[0056] In some embodiments, the network device configures the number of OLPC indication fields for the terminal through high-layer signaling.

[0057] In an implementation, the network device determines whether the terminal supports configuration of multiple OLPC indication fields through the capability information reported by the terminal, and determines the number of OLPC indication fields configured for the terminal based on the capability information.

[0058] In another implementation, the network device configures the number of OLPC indication fields for the terminal based on a protocol specification or a default rule.

[0059] In the embodiments of the present disclosure, when it is determined that the terminal performs STxMP transmission of PUSCH and the terminal supports beam indication based on UnifiedTCI state, one or more OLPC indication fields are configured for the terminal, the power boosting mechanism of OLPC is enhanced, the conflict of different service terminals in STxMP transmission is more reasonably handled, and the terminal and system performance are optimized.

[0060] In the power control parameter determination method provided in the embodiments of the present disclosure, one or more OLPC indication fields are used to determine the open-loop power control parameters corresponding to different PUSCH transmission occasions TO corresponding to different TCI states or different TRPs.

[0061] For example, it is determined that the terminal performs STxMP transmission of PUSCH using TRP1 and TRP2, TRP1 corresponds to TCI state 1, and TRP2 corresponds to TCI state 2. One or more OLPC indication fields are used to indicate the open-loop power control parameters corresponding to PUSCH TO1 corresponding to TCI state 1 / TRP1 and the open-loop power control parameters corresponding to PUSCH TO2 corresponding to TCI state 2 / TRP12.

[0062] In the power control parameter determination method provided in the embodiments of the present disclosure, different PUSCH TOs corresponding to different TCI states or different TRPs are associated with a power parameter set, the power parameter set includes multiple power control configurations, and each power control configuration includes one or more open-loop power control parameters.

[0063] For example, a first PUSCH TO corresponding to a first TCI state or a first TRP is associated with a first power parameter set, such as Uplink_PowerControl, and a second PUSCH TO corresponding to a second TCI state or a second TRP is associated with a second power parameter set, such as P0-PUSCH-AlphaSet.

[0064] In some embodiments, the open-loop power control parameters corresponding to the PUSCH TO corresponding to each TCI state or each TRP are determined from the power control configuration corresponding to the TCI state index in the associated power parameter set.

[0065] For example, the OLPC indication field is used to indicate that the PUSCH TO1 corresponding to the TCI state1 or TRP1 is associated with a power parameter set 1, the power parameter set 1 includes three power control configurations, which are power control configuration 0, power control configuration 1 and power control configuration 2. If the index of the TCI state is TCI state1 and the TCI state1 corresponds to the power control configuration 1, the open-loop power control parameter corresponding to the PUSCH TO1 corresponding to the TCI state1 or TRP1 is determined from the power control configuration 1 in the power parameter set 1. The OLPC indication field is used to indicate that the PUSCH TO2 corresponding to the TCI state2 or TRP2 is associated with the power parameter set 1, the power parameter set 1 includes three power control configurations, which are power control configuration 0, power control configuration 1 and power control configuration 2. If the index of the TCI state is TCI state2 and the TCI state2 corresponds to the power control configuration 2, the open-loop power control parameter corresponding to the PUSCH TO2 corresponding to the TCI state2 or TRP2 is determined from the power control configuration 2 in the power parameter set 1.

[0066] In the embodiments of the present disclosure, by configuring one or more OLPC indication fields, the open-loop power control parameters corresponding to different PUSCH transmission occasions TO corresponding to different TCI states or different TRPs are determined, which more reasonably handles the conflict of different service terminals in the STxMP transmission and optimizes the terminal and system performance.

[0067] In the power control parameter determination method provided in the embodiments of the present disclosure, a single OLPC indication field is configured for the terminal.

[0068] In an implementation, the network device configures one power control parameter set for the terminal, and the power parameter control set includes a first power control parameter set (Uplink_PowerControl) and a second power control parameter set (P0-PUSCH-AlphaSet). That is, the network device configures one first power control parameter set and one second power control parameter set for the terminal, and one OLPC indication field is used to determine the open-loop power control parameters used by different PUSCH TOs corresponding to different TCI states or different TRPs, and the open-loop power control parameters used by different PUSCH TOs corresponding to different TCI states or different TRPs are located in the same power control parameter set. The open-loop power control parameters corresponding to different PUSCH TOs corresponding to different TCI states or different TRPs are determined from the power control parameter set based on different TCI state index values.

[0069] For example, the network device configures a terminal with a first power control parameter set and a second power control parameter set, and the OLPC indication field indicates the first power control parameter set. The OLPC indication field is used to determine, from the first power control parameter set, the power control configuration used by different PUSCH TOs corresponding to different TCI states or different TRPs based on the TCI state index of the different TCI states or different TRPs, and determine the open-loop power control parameters used by the different PUSCH TOs from the respective corresponding power control configuration.

[0070] In another implementation, the network device configures a power control parameter set for each TRP, and the power control parameter set includes a first power control parameter set and a second power control parameter set. That is, the network device configures a terminal with a first power control parameter set and / or a second power control parameter set for each TRP. One OLPC indication field is used to indicate the open-loop power control parameters used by different PUSCH TOs corresponding to different TCI states or different TRPs, which are determined from the power control parameter set corresponding to each TRP, respectively.

[0071] In the embodiments of the present disclosure, if the network device configures a terminal with one OLPC indication field, the one OLPC indication field is used to indicate the open-loop power control parameters used by different PUSCH TOs corresponding to different TCI states or different TRPs, which is more reasonable to handle the conflict of different service terminals in STxMP transmission, and optimizes the terminal and system performance.

[0072] In the power control parameter determination method provided in the embodiments of the present disclosure, the number of bits of at least one OLPC indication field in one or more OLPC indication fields configured for a terminal is 0, and the open-loop power control parameters corresponding to the PUSCH TO corresponding to the TCI state or TRP associated with the at least one OLPC indication field are determined based on a first predefined manner.

[0073] In some embodiments, the first predefined manner includes that the open-loop power control parameters corresponding to the PUSCH TO corresponding to the TCI state or TRP are a first value or a second value of the first power parameter set, and the open-loop power control parameters corresponding to the PUSCH TO corresponding to the TCI state or TRP are determined from the second power parameter set.

[0074] For example, if the number of bits of the OLPC indication field 1 is 0, the open-loop power control parameters corresponding to the PUSCH TO corresponding to the TCI state or TRP associated with the OLPC indication field 1 are a first value of the first power parameter set.

[0075] In the embodiments of the present disclosure, if the number of bits of at least one OLPC indication field configured by the network device for the terminal is 0, the open-loop power control parameters corresponding to the PUSCH TO corresponding to the TCI state or the TRP corresponding to the at least one OLPC indication field are determined based on a predefined manner.

[0076] In the method for determining power control parameters provided in the embodiments of the present disclosure, a plurality of OLPC indication fields are configured for the terminal, and different OLPC indication fields in the plurality of OLPC indication fields are respectively used to determine the open-loop power control parameters corresponding to different PUSCH TOs corresponding to different TCI states or different TRPs.

[0077] In some embodiments, the first OLPC indication field is used to determine the first open-loop power control parameter corresponding to the first PUSCH TO corresponding to the first TCI state or the first TRP. Specifically, the first power control configuration is determined from the power parameter set associated with the first PUSCH TO corresponding to the first TCI state or the first TRP based on the index of the first TCI state, and the first open-loop power control parameter is the open-loop power control parameter included in the first power control configuration.

[0078] In the method for determining power control parameters provided in the embodiments of the present disclosure, the number of open-loop power control parameters included in each power control configuration in the first power parameter set is 1, 2 or 3, and the number of bits and the code points of each OLPC indication field in the plurality of OLPC indication fields are the same or different.

[0079] In the embodiments of the present disclosure, the network device independently configures each OLPC indication field, and indicates the open-loop power control parameters corresponding to the PUSCH TO corresponding to the TCI state or the TRP corresponding to each OLPC indication field through the number of bits and the code points of each OLPC indication field, so that the conflict of different service terminals in STxMP transmission is more reasonably handled, and the terminal and system performance are optimized.

[0080] In the method for determining power control parameters provided in the embodiments of the present disclosure, the number of bits of at least one OLPC indication field in the plurality of OLPC indication fields is 1, and different code points of the at least one OLPC indication field are used to indicate the open-loop power control parameters in the same or different power parameter sets.

[0081] In the method for determining power control parameters provided in the embodiments of the present disclosure, the number of open-loop power control parameters included in each power control configuration in the first power parameter set is 1, the number of bits of the at least one OLPC indication field is 1, and the open-loop power control parameter applied to the panel is determined through the 1-bit indication.

[0082] In some embodiments, a first codepoint of the at least one OLPC indication field is used to indicate an open-loop power control parameter in the second set of power parameters; and a second codepoint of the at least one OLPC indication field is used to indicate a first open-loop power control parameter in a corresponding power control configuration in the first set of power parameters.

[0083] In some embodiments, the second set of power parameters can be P0-PUSCH-AlphaSet, and the first set of power parameters can be Uplink_PowerControl.

[0084] In an implementation, when the first codepoint of the at least one OLPC indication field is 0, the corresponding open-loop power control parameter of the PUSCH TO corresponding to the TCI state or the TRP associated with the at least one OLPC indication field is an open-loop power control parameter in the second set of power parameters; and when the second codepoint of the at least one OLPC indication field is 1, the corresponding open-loop power control parameter of the PUSCH TO corresponding to the TCI state or the TRP associated with the at least one OLPC indication field is a first open-loop power control parameter in a corresponding power control configuration in the first set of power parameters.

[0085] In some embodiments, the power control configuration of the PUSCH TO corresponding to the TCI state or the TRP is determined based on a TCI state index.

[0086] In the embodiments of the present disclosure, the number of open-loop power control parameters included in each power control configuration in the first set of power parameters is 1, and power boosting for URLLC is not supported.

[0087] In the power control parameter determination method provided in the embodiments of the present disclosure, the number of open-loop power control parameters included in each power control configuration in the first set of power parameters is 2, the number of bits of the at least one OLPC indication field is 1, and the open-loop power control parameter applied to the corresponding panel is determined through 1-bit indication.

[0120] The embodiments of the present disclosure further provide a method for configuring an OLPC indication field. A network device configures one or more OLPC indication fields for a terminal based on capability information of the terminal by receiving the capability information sent by the terminal.

[0121] In some embodiments, the network device determines, based on the capability information, that the terminal does not support configuring multiple OLPC indication fields, and configures one OLPC indication field for the terminal.

[0122] In some embodiments, the network device determines, based on the capability information, that the terminal supports configuring multiple OLPC indication fields, and configures one OLPC indication field for the terminal.

[0123] In some embodiments, the network device determines, based on the capability information, that the terminal supports configuring multiple OLPC indication fields, and configures the terminal with multiple OLPC indication fields.

[0125] Based on the same concept, the embodiments of the present disclosure also provide a power control parameter determination method applied to a terminal.

[0126] Figure 6 is a flowchart of a power control parameter determination method according to an exemplary embodiment, as shown in Figure 6 The power control parameter determination is performed by the terminal, and includes the following steps.

[0127] In step S21, in response to the terminal supporting unified transmission configuration indication state (Unified TCI state) indicating a beam, one or more OLPC indication fields under STxMP of PUSCH are determined based on configuration information.

[0128] In some embodiments, the configuration information is issued by the network device. The network device configures the number of OLPC indication fields for the terminal based on the capability information sent by the terminal through high-layer signaling. In other embodiments, the configuration information is determined by the terminal based on a protocol or a predefined specification.

[0129] For example, the terminal supports configuring multiple OLPC indication fields, and the network device can configure the number of OLPC indication fields for the terminal to be 2 through high-layer signaling.

[0130] In the power control parameter determination method provided in the embodiments of the present disclosure, the terminal determines the open-loop power control parameters corresponding to different PUSCH TOs corresponding to different TCI states or different TRPs based on one or more OLPC indication fields, as shown in Figure 7 includes the following steps:

[0131] In step S31, the open-loop power control parameters corresponding to different PUSCH TOs corresponding to different TCI states or different TRPs are determined based on one or more OLPC indication fields.

[0132] For example, the terminal performs the STxMP transmission of the PUSCH using the TRP1 and the TRP2, the TRP1 corresponds to the TCI state 1, and the TRP2 corresponds to the TCI state 2, and the terminal can determine the open-loop power control parameter corresponding to the PUSCH TO1 corresponding to the TCI state 1 / TRP1 and the open-loop power control parameter corresponding to the PUSCH TO2 corresponding to the TCI state 2 / TRP12 based on one or more OLPC indication fields.

[0133] In the power control parameter determination method provided in the embodiments of the present disclosure, different PUSCH TOs corresponding to different TCI states or different TRPs are associated with different power parameter sets, and the power parameter set includes a plurality of power control configurations, and each power control configuration includes one or more open-loop power control parameters.

[0134] For example, the first PUSCH TO corresponding to the first TCI state or the first TRP is associated with the first power parameter set, for example, Uplink_PowerControl, and the second PUSCH TO corresponding to the second TCI state or the second TRP is associated with the second power parameter set, for example, P0-PUSCH-AlphaSet.

[0135] In some embodiments, the open-loop power control parameter corresponding to the PUSCH TO corresponding to each TCI state or each TRP is determined from the associated power parameter set based on the power control configuration corresponding to the TCI state index.

[0136] For example, the OLPC indication field is used to indicate that the PUSCH TO1 corresponding to the TCI state1 or TRP1 is associated with a power parameter set 1, the power parameter set 1 includes three power control configurations, which are power control configuration 0, power control configuration 1 and power control configuration 2, the index of the TCI state is TCI state1, and the TCI state1 corresponds to the power control configuration 1, and then the open-loop power control parameter corresponding to the PUSCH TO1 corresponding to the TCI state1 or TRP1 is determined from the power control configuration 1 in the power parameter set 1. The OLPC indication field is used to indicate that the PUSCH TO2 corresponding to the TCI state2 or TRP2 is associated with the power parameter set 1, the power parameter set 1 includes three power control configurations, which are power control configuration 0, power control configuration 1 and power control configuration 2, if the index of the TCI state is TCI state2, and the TCI state2 corresponds to the power control configuration 2, and then the open-loop power control parameter corresponding to the PUSCH TO2 corresponding to the TCI state2 or TRP2 is determined from the power control configuration 2 in the power parameter set 1.

[0137] In the embodiments of the present disclosure, by configuring one or more OLPC indication fields, the open-loop power control parameters corresponding to different PUSCH transmission occasions TO corresponding to different TCI states or different TRPs are determined, and the conflict of different service terminals for STxMP transmission is more reasonably handled, and the terminal and system performance are optimized.

[0138] In the power control parameter determination method provided in the embodiments of the present disclosure, the terminal determines a single OLPC indication field based on configuration information.

[0139] In an implementation, the network device configures a terminal with one power control parameter set, and the power parameter control set includes a first power control parameter set (Uplink_PowerControl) and a second power control parameter set (P0-PUSCH-AlphaSet). That is, the network device configures the terminal with a first power control parameter set and a second power control parameter set, and then one OLPC indication field is used to determine the open-loop power control parameters used by different PUSCH TOs corresponding to different TCI states or different TRPs, and the open-loop power control parameters used by different PUSCH TOs corresponding to different TCI states or different TRPs are located in the same power control parameter set. The open-loop power control parameters corresponding to different PUSCH TOs corresponding to different TCI states or different TRPs are determined from the power control parameter set based on different TCI state index values.

[0140] For example, the network device configures a terminal with a first power control parameter set and a second power control parameter set, and an OLPC indication field indicates the first power control parameter set. The OLPC indication field is used to determine, from the first power control parameter set, a power control configuration used by different PUSCH TOs corresponding to different TCI states or different TRPs based on indexes of the different TCI states or the TCI states of the different TRPs, and determine, from the respective power control configurations, respective open-loop power control parameters used by the different PUSCH TOs.

[0141] In another implementation, the network device configures a power control parameter set for each TRP, and the power control parameter set includes a first power control parameter set and a second power control parameter set. That is, the network device configures a terminal with a first power control parameter set and / or a second power control parameter set for each TRP. An OLPC indication field is used to indicate, from the power control parameter set corresponding to each TRP, an open-loop power control parameter used by different PUSCH TOs corresponding to different TCI states or different TRPs.

[0142] In the embodiments of the present disclosure, when the terminal determines an OLPC indication field based on the configuration information, the terminal can determine, based on the one OLPC indication field, open-loop power control parameters corresponding to different PUSCH TOs corresponding to different TCI states or different TRPs, more reasonably handle conflicts of different service terminals when performing STxMP transmission, and optimize terminal and system performance.

[0143] In the power control parameter determination method provided in the embodiments of the present disclosure, if the number of bits of the OLPC indication field configured by the network device is 0, the terminal determines, based on a predefined manner, an open-loop power control parameter corresponding to a PUSCH transmission occasion TO corresponding to a TCI state or a TRP associated with the OLPC indication field, as shown in the following table. Figure 8

[0144] In step S41, it is determined that the number of bits of at least one OLPC indication field in a plurality of OLPC indication fields is 0.

[0145] In step S42, an open-loop power control parameter corresponding to a PUSCH transmission occasion TO corresponding to a TCI state or a TRP associated with the at least one OLPC indication field is determined based on a first predefined manner.

[0146] ​In some embodiments, the first predefined manner comprises: the open-loop power control parameter corresponding to the PUSCH TO corresponding to the TCI state or the TRP corresponding to the first or second value of the first power parameter set, or the open-loop power control parameter corresponding to the PUSCH TO corresponding to the TCI state or the TRP is determined from the second power parameter set.

[0147] For example, if the number of bits of the OLPC indication domain 1 is 0, the open-loop power control parameter corresponding to the PUSCH TO corresponding to the TCI state or the TRP associated with the OLPC indication domain 1 is the first value of the first power parameter set.

[0148] In the embodiments of the present disclosure, if the number of bits of at least one OLPC indication domain configured by the network device for the terminal is 0, the terminal determines the open-loop power control parameter corresponding to the PUSCH TO corresponding to the TCI state or the TRP associated with the at least one OLPC indication domain based on a predefined manner.

[0151] In step S52, the open-loop power control parameters corresponding to different PUSCH TOs corresponding to different TCI states or different TRPs are determined based on different OLPC indication domains in the plurality of OLPC indication domains.
