Description

Technical Field

[0001] The present disclosure relates to the field of communication technologies, and in particular, to an open-loop power control method, apparatus, and storage medium for an uplink PUSCH. Background Art

[0002] With the development of communication technologies, to ensure the coverage range, beam-based transmission and reception need to be used. When a network device (such as a base station) has multiple transmission reception points (TRPs), multiple TRPs / multi-panels can be used to provide services for a terminal. The application of multiple TRP / multi-panel network devices is mainly to improve the coverage at the cell edge, provide a more balanced quality of service within the service area, and cooperate to transmit data among multiple TRPs / multi-panels in different ways. Considering from the perspective of network form, it will be more beneficial to deploy the network in the way of a large number of distributed access points plus centralized baseband processing to provide a balanced user experience rate, and significantly reduce the delay and signaling overhead caused by handover. By using the cooperation between multiple TRPs / multi-panels, the channel is transmitted / received from multiple beams from multiple angles, which can better overcome various occlusion / blocking effects, ensure the robustness of the link connection, and is suitable for improving the transmission quality and meeting the reliability requirements of ultra-reliable low-latency communication (URLLC) services.

[0003] In the R16 research stage, based on the application of the multi-point cooperative transmission technology between downlink multi-TRP / multi-panels, the transmission of the physical downlink shared channel (PDSCH) was enhanced. Since data transmission includes the scheduling feedback of the uplink and downlink channels. Therefore, in the research of URLLC, only enhancing the downlink data channel cannot guarantee the service performance. Therefore, in the R17 research, the enhancement of the downlink control channel (physical downlink control channel, PDCCH), the uplink control channel (physical uplink control channel, PUCCH), and the uplink shared channel (physical uplink shared channel, PUSCH) was continued.

[0004] In a communication system, there are data services with different priorities, latency requirements, or reliability requirements. For example, the Ultra-Reliable and Low-Latency Communication (URLLC) service has extremely high requirements for both latency and reliability, while the Enhanced Mobile Broadband (eMBB) service has relatively lower requirements for latency and reliability. Usually, URLLC is scheduled with a shorter transmission time interval. Moreover, the URLLC service is bursty and random, showing a scattered characteristic in resource distribution, resulting in a low resource utilization rate. Therefore, it is considered to multiplex with eMBB transmission to improve the resource utilization rate. Different from downlink transmission, when a terminal sends uplink data, it cannot determine whether the transmission resources of the service data overlap with the services of different priorities transmitted by other terminals. To ensure the reliability of URLLC service transmission, R16 introduces an Open-loop power control parameter set indication in the downlink control information (DCI) to indicate the power boosting indication function for scheduling the Physical Uplink Shared Channel (PUSCH), and introduces a new Radio Resource Control (RRC) parameter: P0-PUSCH-Set, which is used to indicate power control. In the related art, each Sounding Reference Signal (SRS) Resource Indication (SRI) corresponds to a P0-PUSCH-Set parameter for open-loop power control and is indicated by the Open-loop power control parameter set indication.

[0005] For the PUSCH enhancement based on multi-Transmission and Reception Point (TRP) / Panel in R17, in the transmission scenario of PUSCH, there will be URLLC services transmitted based on multi-TRP, and conflicts with eMBB services occur on different TRPs, that is, the conflict interference situations received by two TRPs on the network device side are different. How to enhance the power boosting mechanism of open-loop power control (OLPC) for multi-TRP is a research topic that needs to be studied. Summary of the Invention

The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure.

[0092] The open-loop power control method for uplink PUSCH provided by the embodiments of the present disclosure can be applied to Figure 1 the wireless communication system shown. Refer to Figure 1 shown, the wireless communication system includes a network device and a terminal. The terminal is connected to the network device through wireless resources and conducts data transmission. Among them, data transmission between the network device and the terminal is based on a beam. Among them, the enhancement of PUSCH uplink transmission can be performed between the network device and the terminal based on Multi-TRP.

[0093] It can be understood that the number of TRPs for the network device to conduct data transmission with the terminal based on Multi-TRP can be one or more. Figure 1 The data transmission between the network device and the terminals 1 and 2 based on TRP1 and TRP2 in the wireless communication system shown is only for illustrative purposes and is not to be construed as limiting.

[0094] It can be further understood that Figure 1 The wireless communication system shown is only for illustrative purposes. Other network devices may also be included in the wireless communication system. For example, core network devices, wireless relay devices, and wireless backhaul devices may also be included, which are not drawn in Figure 1 The number of network devices and the number of terminals included in the wireless communication system are not limited in the embodiments of the present disclosure.

[0095] It can be further understood that the wireless communication system in the embodiments of the present disclosure is a network that provides wireless communication functions. The wireless communication system can adopt 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 FDMA (SC-FDMA), Carrier Sense Multiple Access with Collision Avoidance. According to factors such as the capacity, rate, and latency of different networks, the network can be divided into 2G (generation) networks, 3G networks, 4G networks, or future evolved networks, such as 5G networks. 5G networks can also be referred to as New Radio (NR). For the convenience of description, the wireless communication network is sometimes simply referred to as the network in the present disclosure.

[0096] Further, the network device involved in the present disclosure may also be referred to as a radio access network device. The radio access network device may be: a base station, an evolved node B (eNodeB), 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), or a transmission and reception point (TRP), etc. It may also be a gNB in the NR system, or it may also be a component or part of a device that constitutes a base station, etc. It should be understood that in the embodiments of the present disclosure, the specific technologies and specific device forms adopted by the network device are not limited. In the present disclosure, the network device may provide communication coverage for a specific geographical area and may communicate with terminals located within the coverage area (cell). In addition, when it is a vehicle-to-everything (V2X) communication system, the network device may also be a vehicle-mounted device.

[0097] Further, the terminal involved in the present disclosure may also be referred to as a terminal device, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc. It is a device that provides voice and / or data connectivity to users. For example, the terminal may be a handheld device with a wireless connection function, a vehicle-mounted device, etc. Currently, some examples of terminals are: a smart phone, a customer premise equipment (CPE), a pocket personal computer (PPC), a palm computer, 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 may also be a vehicle-mounted device. It should be understood that the embodiments of the present disclosure do not limit the specific technologies and specific device forms adopted by the terminal.

[0098] In the present disclosure, open-loop power control can be performed between a network device and a terminal. R16 introduces an Open-loop power control parameter set indication in the scheduling DCI to indicate the power boosting indication function for scheduling PUSCH, and introduces a new RRC parameter P0-PUSCH-Set to indicate power control. Each SRI corresponds to a P0-PUSCH-Set parameter for open-loop power control, and is indicated through an Open-loop power control parameter set indication field.

[0099] Among them, the network device notifies the terminal whether there is an open-loop power control parameter indication field through the high-layer signaling p0-PUSCH-SetList-r16. When the high-layer parameter p0-PUSCH-SetList-r16 is not configured, the open-loop power control parameter indication field is 0 bits, that is, the open-loop power control parameter indication field does not exist, and the terminal obtains P0 from the P0-PUSCH-AlphaSet according to the original Rel-15 mechanism. When the high-layer parameter p0-PUSCH-SetList-r16 is configured, the open-loop power control parameter indication field can be configured as 1 bit or 2 bits through high-layer signaling, where:

[0100] 1) When there is an SRI indication field in the DCI, the open-loop power control parameter indication field is configured as 1 bit.

[0101] 2) When there is no SRI indication field in the DCI, the open-loop power control parameter indication field can be configured as 1 bit or 2 bits according to high-layer signaling.

[0102] 3) For the scenario where there is an SRI indication field in the above DCI, if the open-loop power control parameter indication field information is "0", the Rel-15 mechanism is still used to obtain P0 from the P0-PUSCH-AlphaSet according to the SRI indication. If the open-loop power control parameter indication field information is "1", the terminal obtains P0 from the open-loop parameter set P0-PUSCH-Set for power boosting according to the SRI indication.

[0103] For the scenario where there is no SRI field in the DCI, RAN1#99 meeting passed that the open-loop power control indication field in the DCI can be configured as 1 bit or 2 bits, and the P0-PUSCH-Set parameter can be configured with at most two P0 values.

[0104] The scenario to which the open-loop power control method of the uplink PUSCH in the embodiments of the present disclosure is applied is the scenario where power control parameter adjustment occurs during a service conflict in the communication process of the terminal. For example, Figure 1Among them, terminal 1 conducts URLLC services and eMBB services, and terminal 2 conducts eMBB services. The starting point of the embodiments of the present disclosure is that when there is a conflict between terminal 1 configured with both eMBB and URLLC services and terminal 2 configured with eMBB services, terminal 1 requires three different open-loop power levels for power boosting of eMBB and URLLC, which are respectively: 1) baseline P0 for eMBB, obtained from P0 - PUSCH - AlphaSet; 2) higher P0, used for power boosting of URLLC services that do not conflict with eMBB; 3) highest P0, used for URLLC PUSCH that conflicts with eMBB.

[0105] To more clearly describe how the terminal determines P0 according to high-layer parameters and DCI indications, reference can be made to Table 1 shown below. Table 1 shows how the terminal determines P0 according to high-layer parameters and DCI indications.

[0107]

[0108] In the related art, data transmission is based on beams between network devices and terminals. In R17, the network device and the terminal can enhance the PUSCH uplink transmission based on Multi-TRP. For the PUSCH enhancement scheme based on multi-TRP, there will also be a situation where URLLC services transmitted based on multi-TRP at different TRPs conflict with eMBB services. That is, the conflict interference situations received by two TRPs of the network device are different. According to the current adjustment method, since the scheduling PUSCH with conflicts corresponds to a power boosting adjustment parameter of an open-loop power, and the terminal does not know which TRP's resources have conflicts. Therefore, the open-loop power can only be adjusted based on the power boosting parameter of the same open-loop power in two different TRP transmission directions at the same time, which will cause the terminal to waste precious transmission power, directly increase the interference to other users, and cause problems of reducing system performance. Therefore, it is necessary to enhance the power boosting mechanism of OLPC.

[0109] The embodiments of the present disclosure provide an open-loop power control method for uplink PUSCH. In this open-loop power control method for uplink PUSCH, power boosting parameters corresponding to one or more TRPs are configured for the terminal, and the power boosting parameters used when multiple TRPs cooperate to send PUSCH are indicated. The power boosting parameters used when sending PUSCH correspond to different cooperating TRPs for sending PUSCH, so as to implement an enhanced open-loop power control method for uplink PUSCH.

[0110] For the convenience of description in the embodiments of the present disclosure, the indication information used to indicate the power boost parameters used when multiple TRPs cooperate to transmit PUSCH is referred to as the first indication information.

[0111] Figure 2 It is a flowchart of an open-loop power control method for uplink PUSCH shown according to an exemplary embodiment. As Figure 2 shown, the open-loop power control method for uplink PUSCH includes the following steps.

[0112] In step S11, configure and determine the OLPC parameters required by the terminal. The OLPC parameters include the power boost parameters corresponding to one or more TRPs.

[0113] In step S12, send the first indication information, which is used to indicate the power boost parameters used when multiple TRPs cooperate to transmit PUSCH. Among them, the power boost parameters used when transmitting PUSCH correspond to different cooperating TRPs for transmitting PUSCH.

[0115] In one implementation manner of the open-loop power control method for uplink PUSCH provided by the embodiments of the present disclosure, the RRC configuration of the power boost parameters of OLPC can be enhanced to support configuring different power boost parameters for PUSCH transmitted to different TRPs.

[0116] Figure 3 It is a flowchart of an open-loop power control method for uplink PUSCH shown according to an exemplary embodiment. Refer to Figure 3 shown, the open-loop power control method for uplink PUSCH includes the following steps:

[0117] In step S21, based on the RRC configuration information, determine the OLPC parameters. Among them, the RRC configuration information is used to configure respective power boost parameters for PUSCH transmitted to different TRPs.

[0118] In the open-loop power control method of the uplink PUSCH provided by the embodiments of the present disclosure, the extended enhanced RRC configuration information can be enhanced in at least one of the following ways to support the configuration of PUSCH power boost control parameters extended to multiple TRPs.

[0119] Method 1: Add a set configuration of PUSCH power boost parameters (p0-PUSCH-SetList-r16), corresponding to different SRS resource sets respectively. In this case, the corresponding RRC configuration information includes multiple sets of PUSCH power boost parameter configurations, and different PUSCH power boost parameter configurations in the multiple sets of PUSCH power boost parameter configurations correspond to different SRS resource sets.

[0120] Method 2: Add a configuration of an SRI resource set identifier (sri-resource-setId) to each P0-PUSCH-Set-r16 to indicate a specific SRS resource set. That is, the RRC configuration information includes an SRI resource set identifier, and the PUSCH power boost parameter configuration set establishes a corresponding relationship with the SRS resource set through the SRI resource set identifier.

[0121] Method 3: Add a configuration of a "p0-List-r16" to each P0-PUSCH-Set-r16 for extended P0 indication. That is, the RRC configuration information includes multiple sets of power parameter configurations, and the multiple sets of power parameter configurations are included in the PUSCH power boost parameter configuration set.

[0122] In the open-loop power control method of the uplink PUSCH provided by the embodiments of the present disclosure, it is necessary to enhance the power indication of OLPC in DCI to support indicating different power boost parameters for PUSCHs sent to different TRPs respectively. That is, in the embodiments of the present disclosure, the network device can send a first indication message through DCI.

[0123] Figure 4 is a flowchart of an open-loop power control method of an uplink PUSCH shown according to an exemplary embodiment. Refer to Figure 4 The open-loop power control method of the uplink PUSCH shown includes the following steps:

[0124] In step S31, a first indication message is sent based on DCI.

[0125] In the open-loop power control method of the uplink PUSCH provided by the embodiments of the present disclosure, the DCI field can be extended, and the PUSCH transmission power boost parameters for different TRPs can be independently indicated based on the extended DCI field. In one example, in the embodiments of the present disclosure, the DCI fields used to independently indicate the PUSCH transmission power boost parameters for different TRPs are referred to as the first indication field and the second indication field. Among them, the first indication field is used to indicate the PUSCH transmission power boost parameters for the first TRP, and the second indication field is used to indicate the PUSCH transmission power boost parameters for the second TRP.

[0126] For the power control method of the uplink PUSCH provided by the embodiments of the present disclosure, if the DCI includes SRI indication information indicating transmission to different TRPs, then a 1-bit indication field can be extended, and each indication field is respectively used to indicate whether to indicate the power boost parameter. That is, for different cooperating TRPs transmitting PUSCH, in the open-loop power parameter sets indicated by the first indication field or the second indication field in the DCI respectively, through the SRI indication information indicated in the direction of this TRP, the PUSCH transmission power boost parameter in the corresponding power parameter set is obtained by association.

[0127] For the power control method of the uplink PUSCH provided by the embodiments of the present disclosure, if the DCI does not have SRI indication information indicating transmission to the corresponding different TRPs, then for different cooperating TRPs transmitting PUSCH, the PUSCH transmission power boost parameters in the direction of this TRP are respectively associated in the power parameter sets indicated by the first indication field or the second indication field. That is, in the case where there is no SRI field in the DCI, a 1-bit indication field or a 2-bit indication field can be extended, and each indication field is respectively used to indicate whether to indicate the power boost parameter and to indicate which indication power boost parameter to specifically use.

[0128] Furthermore, the open-loop power parameter sets indicated by the first indication field and / or the second indication field in the embodiments of the present disclosure can be P0-PUSCH-AlphaSet in the Rel-15 mechanism, or p0-PUSCH-SetList-r16 in the R-16 mechanism.

[0129] In the open-loop power control method of the uplink PUSCH provided by the embodiments of the present disclosure, the DCI field can be extended, and the PUSCH transmission power boost parameters for different TRPs can be jointly indicated based on the extended DCI field.

[0130] In one example, in the embodiments of the present disclosure, the power boost parameters for PUSCH transmissions to different TRPs are jointly indicated through an extended DCI field, which may be corresponding to one or more TRPs associated with PUSCH transmissions through the OLPC power code points and associated with the PUSCH power set corresponding to the TRP.

[0131] In one example, in the embodiments of the present disclosure, if the DCI includes SRI indication information indicating transmissions to different TRPs, the schematic correspondence between the OLPC power code points and the one or more TRPs associated with PUSCH transmissions, which is also associated with the PUSCH power set corresponding to the TRP, can be referred to Table 2 and Table 3 below.

[0132] Among them, Table 2 shows that the DCI includes SRI indication information indicating transmissions to different TRPs, and the correspondence between the OLPC power code points and the TRPs associated with PUSCH transmissions is indicated by 2 bits.

[0138]

[0139] Among them, Table 3 shows that the DCI includes SRI indication information indicating transmissions to different TRPs, and the correspondence between the OLPC power code points and the TRPs associated with PUSCH transmissions is indicated by 3 bits.

[0140] It can be understood that as shown in Table 2 and Table 3 in the embodiments of the present disclosure, by introducing the support of 2 P0 values, the power control boost when the terminal is simultaneously configured with eMBB and URLLC services and conflicts with eMBB terminals is increased. Further, the correspondence between the OLPC power code points and the TRPs associated with PUSCH transmissions shown in Table 2 and Table 3 in the embodiments of the present disclosure is only for illustrative purposes and is not limited thereto. There may be other correspondences.

[0141] In one example, in the embodiments of the present disclosure, if the DCI does not include SRI indication information indicating transmissions to different TRPs, the schematic correspondence between the OLPC power code points and the one or more TRPs associated with PUSCH transmissions, which is also associated with the PUSCH power set corresponding to the TRP, can be referred to Table 4 below.

[0144]

[0145] Among them, Table 4 shows that there is no SRI indication information indicating transmission to different TRPs in DCI, and the correspondence between the OLPC power code point and the TRP associated with PUSCH transmission is indicated by 3 bits.

[0146] It can be understood that the correspondence between the OLPC power code point and the TRP associated with PUSCH transmission shown in Table 3 in the embodiments of the present disclosure is only for illustrative purposes and is not limiting. There may be other corresponding relationships.

[0147] In another implementation manner of the open-loop power control method for the uplink PUSCH provided by the embodiments of the present disclosure, the power boost parameter used when multiple TRPs cooperate to transmit PUSCH can be indicated by extending the transmit power control (TPC) indication information. That is, in the embodiments of the present disclosure, the first indication information can be sent based on TPC.

[0148] In an open-loop power control method for an uplink PUSCH provided by an embodiment of the present disclosure, first, the enhanced RRC configuration information needs to be enhanced in the following manner to support the configuration of PUSCH power boost control parameters extended to multiple TRPs: Add a set configuration of PUSCH power boost parameters (p0-PUSCH-SetList-r16), which respectively correspond to different SRS resource sets. In this case, the corresponding RRC configuration information includes multiple sets of PUSCH power boost parameter configurations, and different sets of PUSCH power boost parameter configurations in the multiple sets of PUSCH power boost parameter configurations correspond to different SRS resource sets.

[0149] Secondly, the DCI field can be enhanced to independently indicate the PUSCH transmission power boost parameters for different TRPs based on the extended DCI field. In one example, in the embodiments of the present disclosure, the DCI field in the DCI used to independently indicate the PUSCH transmission power boost parameters for different TRPs is referred to as the first indication field and the second indication field. Among them, the first indication field is used to indicate the PUSCH transmission power boost parameters for the first TRP, and the second indication field is used to indicate the PUSCH transmission power boost parameters for the second TRP. If the DCI includes SRI indication information indicating transmissions to different TRPs, a 1-bit indication field can be extended, and each indication field is respectively used to indicate whether to indicate the power boost parameters. That is, for different cooperating TRPs transmitting PUSCH, in the open-loop power parameter sets indicated by the first indication field or the second indication field in the DCI respectively, through the SRI indication information indicated in the direction of this TRP, the PUSCH transmission power boost parameters in the corresponding power parameter set are associated. If there is no SRI indication information indicating transmissions to different corresponding TRPs in the DCI, for different cooperating TRPs transmitting PUSCH, the PUSCH transmission power boost parameters in the direction of this TRP are respectively associated in the power parameter sets indicated by the first indication field or the second indication field. That is, in the case where there is no SRI field in the DCI, a 1-bit indication field or a 2-bit indication field can be extended, and each indication field is respectively used to indicate whether to indicate the power boost parameters and to indicate which indication power boost parameter to specifically use.

[0150] In another open-loop power control method for the uplink PUSCH provided by the embodiments of the present disclosure, first, the enhanced RRC configuration information needs to be extended and can be enhanced in the following manner to support the configuration of PUSCH power boost control parameters extended to multiple TRPs: Add a set configuration of PUSCH power boost parameters (p0-PUSCH-SetList-r16), which respectively correspond to different SRS resource sets. In this case, the corresponding RRC configuration information includes multiple sets of PUSCH power boost parameters, and different sets of PUSCH power boost parameters in the multiple sets of PUSCH power boost parameters correspond to different SRS resource sets.

[0151] Secondly, the DCI field can be enhanced to jointly indicate PUSCH transmission power boost parameters for different TRPs based on the extended DCI field. In one example, in the embodiments of the present disclosure, the PUSCH transmission power boost parameters for different TRPs are jointly indicated through the extended DCI field, which may be that one or more TRPs associated with the PUSCH transmission are corresponding to the OLPC power code points and are associated with the PUSCH power set corresponding to the TRP. In one example, in the embodiments of the present disclosure, if the DCI includes SRI indication information indicating transmissions to different TRPs, the schematic corresponding relationship in which one or more TRPs associated with the PUSCH transmission are corresponding to the OLPC power code points and are associated with the PUSCH power set corresponding to the TRP can be referred to Tables 2 and 3.

[0152] In an open-loop power control method for an uplink PUSCH provided by the embodiments of the present disclosure, first, the enhanced RRC configuration information needs to be enhanced in the following manner to support the configuration of PUSCH power boost control parameters extended to multiple TRPs: One SRI resource set identifier (sri-resource-setId) is added and configured in each P0-PUSCH-Set-r16 to indicate a specific SRS resource set. That is, the RRC configuration information includes the SRI resource set identifier, and the PUSCH power boost parameter configuration set establishes a corresponding relationship with the SRS resource set through the SRI resource set identifier.

[0153] Second, the DCI field can be enhanced to independently indicate the PUSCH transmission power boost parameters for different TRPs based on the extended DCI field. In one example, in the embodiments of the present disclosure, the DCI fields in the DCI for independently indicating the PUSCH transmission power boost parameters for different TRPs are referred to as the first indication field and the second indication field. Among them, the first indication field is used to indicate the PUSCH transmission power boost parameter for the first TRP, and the second indication field is used to indicate the PUSCH transmission power boost parameter for the second TRP. If the DCI includes SRI indication information indicating transmissions to different TRPs, a 1-bit indication field can be extended, and each indication field is respectively used to indicate whether to indicate the power boost parameter. That is, for different cooperating TRPs transmitting PUSCH, in the open-loop power parameter sets indicated by the first indication field or the second indication field in the DCI respectively, through the SRI indication information indicated in the direction of the TRP, the PUSCH transmission power boost parameter in the transmission direction of the corresponding TRP is obtained by association in the corresponding power parameter set. If there is no SRI indication information indicating transmissions to different corresponding TRPs in the DCI, for different cooperating TRPs transmitting PUSCH, the PUSCH transmission power boost parameters in the transmission direction of the corresponding TRP are respectively associated in the power parameter sets indicated by the first indication field or the second indication field. That is, in the case where there is no SRI field in the DCI, a 1-bit indication field or a 2-bit indication field can be extended, and each indication field is respectively used to indicate whether to indicate the power boost parameter and to indicate which indication power boost parameter to specifically use.

[0154] In another open-loop power control method for uplink PUSCH provided by the embodiments of the present disclosure, first, the enhanced RRC configuration information needs to be extended and can be enhanced in the following manner to support the configuration of PUSCH power boost control parameters extended to multiple TRPs: A SRI resource set identifier (sri-resource-setId) is added and configured in each P0-PUSCH-Set-r16 to indicate a specific SRS resource set. That is, the RRC configuration information includes the SRI resource set identifier, and the PUSCH power boost parameter configuration set establishes a corresponding relationship with the SRS resource set through the SRI resource set identifier.

[0155] Second, the DCI field can be enhanced to jointly indicate PUSCH transmission power boost parameters for different TRPs based on the extended DCI field. In one example, in the embodiments of the present disclosure, the PUSCH transmission power boost parameters for different TRPs are jointly indicated through the extended DCI field, which may be that the OLPC power code point corresponds to one or more TRPs associated with the PUSCH transmission and is associated with the PUSCH power set corresponding to the TRP. In one example, in the embodiments of the present disclosure, if the DCI includes SRI indication information indicating transmissions to different TRPs, the schematic correspondence relationship in which the OLPC power code point corresponds to one or more TRPs associated with the PUSCH transmission and is associated with the PUSCH power set corresponding to the TRP can be referred to Tables 2 and 3.

That is, the RRC configuration information includes multiple sets of power parameter configurations, and the multiple sets of power parameter configurations are included in the PUSCH power boost parameter configuration set.

[0157] Secondly, the DCI field can be enhanced to independently indicate the PUSCH transmission power boost parameters for different TRPs based on the extended DCI field. In one example, in the embodiments of the present disclosure, the DCI fields used to independently indicate the PUSCH transmission power boost parameters for different TRPs in the DCI are referred to as the first indication field and the second indication field. Among them, the first indication field is used to indicate the PUSCH transmission power boost parameter for the first TRP, and the second indication field is used to indicate the PUSCH transmission power boost parameter for the second TRP. If the DCI includes SRI indication information indicating transmissions to different TRPs, a 1-bit indication field can be extended, and each indication field is respectively used to indicate whether to indicate the power boost parameter. That is, for different cooperating TRPs transmitting PUSCH, in the open-loop power parameter sets indicated by the first indication field or the second indication field in the DCI respectively, through the SRI indication information indicated in the direction of the TRP, the PUSCH transmission power boost parameter in the transmission direction of the corresponding TRP is obtained by association in the corresponding power parameter set. If there is no SRI indication information indicating transmissions to different TRPs in the DCI, for different cooperating TRPs transmitting PUSCH, the PUSCH transmission power boost parameters in the transmission direction of the corresponding TRP are respectively associated in the power parameter sets indicated by the first indication field or the second indication field. That is, in the case where there is no SRI field in the DCI, a 1-bit indication field or a 2-bit indication field can be extended, and each indication field is respectively used to indicate whether to indicate the power boost parameter and to indicate which indication power boost parameter to specifically use.

[0158] In another open-loop power control method for the uplink PUSCH provided by the embodiments of the present disclosure, first, the enhanced RRC configuration information needs to be extended and enhanced in the following manner to support the configuration of PUSCH power boost control parameters extended to multiple TRPs: Add a configuration of "p0-List-r16" to each P0-PUSCH-Set-r16 for extended P0 indication. That is, the RRC configuration information includes multiple sets of power parameter configurations, and the multiple sets of power parameter configurations are included in the PUSCH power boost parameter configuration set.

[0159] Secondly, the DCI field can be enhanced to jointly indicate PUSCH transmission power boost parameters for different TRPs based on the extended DCI field.

Further, the power adjustment indication range of each TPC field can determine whether the power adjustment value indicated by TPC uses the adjustment parameter calculated cumulatively based on the control parameter indicated by the second indication information. Wherein, the second indication information may be a TPC command used to indicate calculation based on accumulation. The terminal determines the adjustment parameter based on the TPC command calculated cumulatively. The second indication information may also be a TPC command used to indicate non-cumulative calculation. The terminal determines the adjustment parameter based on the TPC command that is not calculated cumulatively. Wherein, whether to use the TPC command calculated cumulatively is indicated by higher-layer signaling.

[0168] In the embodiments of the present disclosure, the TPC parameters controlled by different TRPs may use an independently indicated TPC control field or a jointly indicated TPC control field. The independent control indication fields are shown in Table 5 below, and the indicated meanings of each TPC correspond to the same table interpretations.
