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 uplink unscheduled PUSCH. Background Art

[0002] With the development of communication technologies, in order 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-TRP) / multi-panels (PANEL) can be used to provide services for a terminal. The application of network device multi-TRP / PANEL is mainly to improve the coverage of the cell edge, provide a more balanced quality of service within the service area, and cooperate to transmit data among multiple TRPs / PANELs in different ways. From the perspective of network form, deploying the network in the way of a large number of distributed access points plus centralized baseband processing will be more conducive to providing a balanced user experience rate, and significantly reducing the delay and signaling overhead caused by handover. By using the cooperation among multiple TRPs / PANELs, transmitting / receiving channels from multiple beams from multiple angles can better overcome various occlusion / blocking effects, ensure the robustness of the link connection, and are 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 multi-point cooperative transmission technology among downlink multi-TRP / PANELs, transmission enhancement was performed on the physical downlink shared channel (PDSCH). 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 service performance. Therefore, in the R17 research, the physical downlink control channel (PDCCH), the physical uplink control channel (PUCCH), and the physical uplink shared channel (PUSCH) were continuously enhanced.

[0004] In a communication system, there are data services with different priorities, latency requirements, or reliability requirements. For example, the 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, and its resource utilization rate is low. Therefore, it is considered to multiplex with eMBB transmission to improve the resource utilization rate. Different from downlink transmission, when a certain 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 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-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 topic that needs to be studied. Summary of the Invention

[0088] The open-loop power control method for uplink unscheduled 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 performs data transmission. Among them, data transmission between the network device and the terminal is based on beams. Among them, the enhancement of PUSCH uplink transmission can be performed between the network device and the terminal based on Multi-TRP.

[0089] It can be understood that the number of TRPs for the network device to perform 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 limiting.

[0090] Furthermore, it can be understood that Figure 1 the wireless communication system shown is only for illustrative purposes, and the wireless communication system may further include other network devices, such as a core network device, a wireless relay device, and a wireless backhaul device, etc., which are not drawn in Figure 1 The present disclosure embodiments do not limit the number of network devices and terminals included in the wireless communication system.

[0091] 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 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) network, 3G network, 4G network, or future evolved network, such as 5G network. The 5G network can also be referred to as the New Radio (NR). For the convenience of description, the wireless communication network is sometimes simply referred to as the network in the present disclosure.

[0092] Furthermore, the network device involved in the present disclosure can also be referred to as a radio access network device. The radio 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), or a transmission and reception point (TRP), etc. It can also be a gNB in the NR system, or it can also be a component or part of a device that constitutes a base station. 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 can provide communication coverage for a specific geographical area and can communicate with terminals located within the coverage area (cell). In addition, when it is a vehicle-to-everything (V2X) communication system, the network device can also be an in-vehicle device.

[0093] Further, the terminal involved in the present disclosure, which may also be referred to as a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., is a device that provides voice and / or data connectivity to users. For example, the terminal may be a handheld device with wireless connection capabilities, a vehicle-mounted device, etc. Currently, some examples of terminals are: mobile phones, customer premise equipment (CPE), pocket personal computers (PPC), palmtop computers, personal digital assistants (PDA), laptop computers, tablet computers, wearable devices, or vehicle-mounted devices, 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 specific technologies and specific device forms adopted by the terminal in the embodiments of the present disclosure are not limited.

[0094] In the present disclosure, open-loop power control can be performed between the network device and the terminal. R16 introduces 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 the Open-loop power control parameter set indication field.

[0095] 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:

[0096] 1) When there is an SRI indication field in the DCI, the open-loop power control parameter indication field is configured as 1 bit.

[0097] 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 the higher-layer signaling.

[0098] 3) For the scenario where there is an SRI indication field in the above DCI, if the information in the open-loop power control parameter indication field is "0", the mechanism of Rel-15 is still used to obtain P0 from P0-PUSCH-AlphaSet according to the SRI indication. If the information in the open-loop power control parameter indication field is "1", the terminal obtains P0 from the open-loop parameter set P0-PUSCH-Set for power boost according to the SRI indication.

[0099] For the scenario where there is no SRI field in the DCI, RAN1#99 meeting passed that the indication field of open-loop power control 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. The scenario where the open-loop power control method of the uplink PUSCH in the embodiments of the present disclosure is applied is the scenario where the power control parameters are adjusted during the communication process of the terminal due to service conflicts. For example, Figure 1 in which, terminal 1 conducts URLLC service and eMBB service, and terminal 2 conducts eMBB service. The starting point of the embodiments of the present disclosure is applied when there is a conflict between terminal 1 configured with both eMBB and URLLC services and terminal 2 configured with eMBB service. Terminal 1 needs three different open-loop power levels for the power boost of eMBB and URLLC, respectively: 1) the baseline P0 for eMBB, obtained from P0-PUSCH-AlphaSet; 2) the higher P0 for the power boost of URLLC services that do not conflict with eMBB; 3) the highest P0 for the URLLC PUSCH that conflicts with eMBB.

[0100] To more clearly describe how the terminal determines P0 according to the higher-layer parameters and DCI indication, reference can be made to Table 1 shown below. Table 1 shows how the terminal determines P0 according to the higher-layer parameters and DCI indication.

[0102]

[0103] In the related art, data transmission is based on beams between the network device and the terminal. In R17, the enhancement of PUSCH uplink transmission can be based on Multi-TRP between the network device and the terminal.

[0104] In the PUSCH enhancement solution based on multi-TRP, there will also be a situation where URLLC services transmitted based on multi-TRP conflict with eMBB services on different TRPs in the PUSCH transmission scenario. Among them, in the configured grant (CG) PUSCH transmission scenario, there is also a situation where URLLC services conflict with eMBB terminal services, and corresponding interference control needs to be considered. Among them, the configured grant PUSCH is also called the configured authorization PUSCH. The configured grant PUSCH transmission is different from the scheduled PUSCH transmission. The network device cannot predict when the terminal will transmit the PUSCH. Moreover, multiple configured grant PUSCH resources can be configured within a Bandwidth Part (BWP), and the resource positions allocated for each configuration may not be the same. The maximum number of configured grant PUSCH configurations supported within a BWP is 12.

[0105] In R17, for the enhancement of PUSCH transmission based on multi-TRP, the main solution is multiple retransmissions based on Time Division Multiplexing (TDM). For the configured grant PUSCH transmission, both the configured grant PUSCH control transmission corresponding to a single configuration and the configured grant PUSCH control transmission that may correspond to multiple configurations are used for the cooperative transmission of the same Transport Block (TB) facing multiple TRPs.

[0106] When eMBB and URLLC services conflict, it is necessary to give priority to ensuring the transmission reliability of URLLC services. R16 enhanced the DG PUSCH and introduced the power boosting function. The configured grant PUSCH was not enhanced.

[0107] Among them, the configured grant PUSCH is different from the scheduled PUSCH. The network device cannot predict when the terminal will transmit the PUSCH. Moreover, one or more configured grant PUSCH resources can be configured for a terminal on a BWP. However, the interference control requirements for handling service conflicts between different terminals still exist. When in the multi-TRP transmission scenario, the conflict situations between PUSCH transmissions and eMBB services facing different TRPs may not be the same, that is, the conflict interference situations received by the two TRPs of the network device are different. If the power control adjustment for the configured grant PUSCH does not distinguish between TRP transmissions, it will cause the terminal to waste transmission power, increase interference to other users, and result in a problem of reducing system performance. Therefore, it is necessary to enhance the powerboosting mechanism of OLPC.

[0108] The embodiments of the present disclosure provide an open-loop power control method for unscheduled PUSCH in the uplink. The network device configures and determines open-loop power boost parameters corresponding to one or more TRPs, and sends indication information to indicate the open-loop power boost parameters of the unscheduled PUSCH configuration adopted for single-TRP independent transmission or multi-TRP cooperative transmission of a transport block TB. Through the present disclosure, control over the open-loop power boost parameters of the unscheduled PUSCH configuration adopted for single-TRP independent transmission or multi-TRP cooperative transmission of TB can be achieved, and thus interference control can be performed to ensure the reliability of communication services.

[0109] Figure 2 is a flowchart of an open-loop power control method for unscheduled PUSCH in the uplink shown according to an exemplary embodiment, as Figure 2 shown, the open-loop power control method for unscheduled PUSCH in the uplink includes the following steps.

[0110] In step S11, configure and determine open-loop power boost parameters corresponding to one or more TRPs.

[0111] In step S12, send indication information, where the indication information is used to indicate the open-loop power boost parameters of the unscheduled PUSCH configuration adopted for single-TRP independent transmission or multi-TRP cooperative transmission of TB.

[0112] In the open-loop power control method for unscheduled PUSCH provided by the embodiments of the present disclosure, control over the open-loop power boost parameters of the unscheduled PUSCH configuration adopted for single-TRP independent transmission or multi-TRP cooperative transmission of TB can be achieved, and thus interference control can be performed to ensure the reliability of communication services.

[0113] In one implementation, in the open-loop power control method for unscheduled PUSCH provided by the embodiments of the present disclosure, the unscheduled PUSCH configuration includes unscheduled PUSCH type 1 and unscheduled PUSCH type 2. Unscheduled PUSCH type 1 can also be referred to as configured grant type 1 (Type 1), and unscheduled PUSCH type 2 can also be referred to as configured grant type 2 (Type 2). Configured grant type 1 (Type 1) and configured grant type 2 (Type 2) support two unscheduled schemes, the difference being the activation method, where:

[0114] Configured grant type 1 (Type 1): The uplink grant is provided by RRC, including the activation of the grant. Once the terminal correctly receives the RRC configuration, the unscheduled PUSCH configuration takes effect immediately.

[0115] Configuration authorization type 2 (Type 2): The RRC provides the transmission period, and the network device realizes the resource activation and the configuration of some transmission parameters through DCI, so as to realize the activation transmission of this authorization configuration. After receiving the activation command, if there is data to send in the buffer, the terminal will transmit according to the pre-configured period. If there is no data, the terminal will not transmit any data. The transmission time of the PDCCH determines the activation time. The terminal confirms the activation / deactivation of the configuration authorization type 2 by sending medium access control (MAC) control signaling in the uplink.

[0116] In one implementation, in the open-loop power control method of the uplink unscheduled PUSCH provided by the embodiments of the present disclosure, the open-loop power boost parameters corresponding to one or more TRPs can be configured and determined based on the RRC configuration information. In the related art, there are no parameters for power boost in the RRC configuration information. Therefore, in the embodiments of the present disclosure, the RRC configuration information can be extended to define the open-loop power boost parameters supporting one or more TRPs in the RRC configuration information.

[0117] Figure 3 It is a flowchart of an open-loop power control method of an uplink unscheduled PUSCH shown according to an exemplary embodiment, as Figure 3 shown, the open-loop power control method of the uplink unscheduled PUSCH includes the following steps.

[0118] In step S21, based on the RRC configuration information, the open-loop power boost parameters of one or more TRPs are configured and determined.

[0119] Among them, the RRC configuration information is used to configure the unscheduled PUSCH adopted for sending TBs in the single-TRP direction or multiple different TRP directions, and indicates the respective open-loop power boost parameters.

[0120] In the open-loop power control method of the uplink unscheduled PUSCH provided by the embodiments of the present disclosure, the open-loop power boost parameters can be configured for each of one or more unscheduled PUSCH configurations. Among them, one or more unscheduled PUSCH configurations are the unscheduled PUSCH configurations adopted for sending the same TB in one or more different TRP directions. That is, the RRC configuration information is used to indicate different open-loop power boost parameters for each of one or more unscheduled PUSCH configurations. Among them, the different open-loop power boost parameters configured in the RRC configuration information are the open-loop power boost parameters corresponding to one or more TRPs.

[0121] In the open-loop power control method for uplink unscheduled PUSCH provided by the embodiments of the present disclosure, when different open-loop power boost parameters are indicated for each of one or more unscheduled PUSCH configurations, it can be multi-TRP transmission for an unscheduled PUSCH corresponding to a single configuration, associating a single unscheduled PUSCH configuration with power control parameters. The mapping with a set of open-loop power boost parameters is achieved through SRI, or the associated mapping with open-loop power boost parameters of different TRPs is achieved through predefined rules. In one implementation, a single unscheduled PUSCH configuration used for transmitting a TB in one or more different TRP directions is associated with a set of power control parameters through the SRI indication information in DCI, and power boost parameters in one or more TRP directions are obtained accordingly. Or in another implementation, a single unscheduled PUSCH configuration used for transmitting a TB in one or more different TRP directions is associated with the power control parameters of different TRPs based on predefined rules, and power boost parameters in one or more TRP directions are obtained accordingly.

[0122] In the open-loop power control method for uplink unscheduled PUSCH provided by the embodiments of the present disclosure, at least one of the following methods can be adopted when associating a single unscheduled PUSCH configuration with power control parameters:

[0123] Method 1: Implement the associated mapping through the SRI codepoint. In the case of one SRI indication field, the SRI indication information indicated by the SRI codepoint and corresponding to one or more TRPs respectively is used to correspondingly associate the power control parameters of one or more TRPs of a single unscheduled PUSCH configuration.

[0124] Method 2: Implement the associated mapping through multiple SRI indication fields. In the case of multiple SRI indication fields, each SRI indication information corresponding to different TRPs is used to correspondingly associate the power control parameters of one or more TRPs of a single unscheduled PUSCH configuration.

[0125] In the open-loop power control method of the uplink unscheduled PUSCH provided by the embodiments of the present disclosure, power control parameter configurations can be performed for multiple unscheduled PUSCH configurations used for transmitting transport blocks (TBs) in multiple different TRP directions, so as to configure open-loop power boost parameters for each of the multiple unscheduled PUSCH configurations used for transmitting TBs in multiple different TRP directions. When different open-loop power boost parameters are indicated for multiple unscheduled PUSCH configurations among one or more unscheduled PUSCH configurations, it can be multi-TRP transmission corresponding to multiple unscheduled PUSCH configurations, associating multiple unscheduled PUSCH configurations with power control parameters. Association with the power control parameters in the TRP transmission direction is achieved through SRI, or association with the power control parameters of the TRP through predefined rules. That is, multiple unscheduled PUSCH configurations used for transmitting TBs in multiple different TRP directions are associated with the power control parameters in the TRP transmission direction through the SRI indication information corresponding to each scheduling configuration, or are associated with the power control parameters of the TRP through predefined rules.

[0126] In the open-loop power control method of the uplink unscheduled PUSCH provided by the embodiments of the present disclosure, multiple different sets of power control parameters can also be configured, and the power control parameters of different TRPs are associated through multiple different sets of power control parameters. That is, different sets of power control parameters are configured, and the transmission parameters used for different TRPs are respectively mapped through different SRI fields.

[0127] In the open-loop power control method of the uplink unscheduled PUSCH provided by the embodiments of the present disclosure, based on the RRC configuration information, after configuring the unscheduled PUSCH configurations used for transmitting TBs in a single TRP direction or multiple different TRP directions, the respective open-loop power boost parameters can be further indicated.

[0128] In one implementation, the embodiments of the present disclosure can indicate the open-loop power boost parameters of the unscheduled PUSCH configuration used for single-TRP independent transmission or multi-TRP cooperative transmission of TBs through DCI.

[0129] Figure 4 is a flowchart of an open-loop power control method of an uplink unscheduled PUSCH shown according to an exemplary embodiment, as Figure 4 shown, the open-loop power control method of the uplink unscheduled PUSCH includes the following steps.

[0130] In step S31, indication information is sent through group-common (GC)-DCI.

[0131] In the embodiments of the present disclosure, by sending indication information through GC-DCI, the power boost parameters for different TRP controls can be indicated through GC-DCI.

[0132] Among them, when the indication information is sent by GC-DCI in the embodiments of the present disclosure, the indication field in the GC-DCI is used to directly indicate multiple sets of power control parameters corresponding to different TRPs for the grant-free PUSCH. Among them, the specific power control parameters indicated by the indication field in the GC-DCI can be network-configured or pre-defined. And, for the single-configuration case, if the SRI indication field in the active DCI contains one SRI indication, it is a single-TRP case; otherwise, it is a multi-TRP case. For the multi-configuration case, the active DCI contains one SRI indication, corresponding to one TRP case.

[0133] In the embodiments of the present disclosure, when indicating the power boost parameters for different TRP controls by GC-DCI, the network device can define relevant indication fields in the GC-DCI to respectively indicate the open-loop power boost parameters for multi-TRP sent to different TRPs corresponding to the SRI indication, so as to indicate the CG PUSCH sent for all configurations of this terminal.

[0134] Among them, for the convenience of description, the information field that indicates all grant-free PUSCH configurations applicable to the terminal in the DC-DCI and the different open-loop power boost parameters corresponding to multi-TRP sent to different TRPs is called the first information field. The first information field is used to indicate the different open-loop power boost parameters corresponding to multi-TRP sent to different TRPs, and the multi-TRP sent to different TRPs is indicated by the SRI indication field in the DCI. Among them, the open-loop power boost parameters are applicable to all grant-free PUSCH configurations adopted for multi-TRP collaborative transmission of TB.

[0135] In the embodiments of the present disclosure, when indicating the power boost parameters for different TRP controls by GC-DCI, if there is no SRI indication field in the DCI, there is a pre-defined association indication relationship between the open-loop power boost parameters of multi-TRP sent to different TRPs and the grant-free PUSCH configuration. In one example, if there is no SRI indication field in the DCI, the default value in the pre-defined used list can be used. For example, the first P0 value in the P0 power parameter list indicated by the corresponding TRP is used.

[0136] In the embodiments of the present disclosure, when indicating the power boost parameters for different TRP controls by GC-DCI, the network device can define relevant indication fields for each configured resource in the GC-DCI to respectively indicate the open-loop power boost parameters for multi-TRP of different TRPs corresponding to the SRI indication. Among them, this indication only acts on the corresponding CGPUSCH configuration indicated by the base station.

[0137] For the convenience of description, the information field in DC-DCI that indicates the configuration of the grant-free PUSCH applicable to the indication of the network device and the different open-loop power boost parameters corresponding to multiple TRPs sent to different TRPs is referred to as the second information field. The second information field is used to indicate the PUSCH open-loop power boost parameters in the transmission directions of different TRPs in the SRI indication information corresponding to one or more grant-free PUSCH configurations, or to indicate the PUSCH open-loop power boost parameters in the transmission directions of different TRPs corresponding to all grant-free PUSCH configurations. Among them, the open-loop power boost parameter is applicable to a single grant-free PUSCH configuration. Among them, the single grant-free PUSCH configuration may be the grant-free PUSCH configuration indicated by the network device.

[0138] In the embodiments of the present disclosure, when the power boost parameters for different TRP controls are indicated by GC-DCI, if there is no SRI indication field in the DCI, there is a predefined association indication relationship between the open-loop power boost parameters of multiple TRPs sent to different TRPs and the grant-free PUSCH configuration. In one example, if there is no SRI indication field in the DCI, the default value in the predefined list can be used. For example, the first P0 value in the P0 power parameter list corresponding to the TRP indication is used.

[0139] In the embodiments of the present disclosure, the GC-DCI can be configured to indicate parameters only for one or more configurations that need to be boosted, or to indicate parameters for all scheduling configurations configured for the terminal. Among them, those that do not need to be adjusted can be invalid. This method can correspond to different GC-DCI designs.

[0140] In the open-loop power control method of the uplink grant-free PUSCH provided by the embodiments of the present disclosure, the network device can indicate the time-frequency resource position where the time-frequency resources conflict when the terminal communicates with other users in the GC-DCI, such as the time-frequency resource position of the eMBB where conflicts may occur. The terminal is based on the indication information sent by the network device, and the terminal determines whether it is affected by the time-frequency resource conflict. If the terminal determines that it is affected by the time-frequency resource conflict, the terminal performs power boost operations for different TRPs respectively.

[0141] In the open-loop power control method of the uplink grant-free PUSCH provided by the embodiments of the present disclosure, for the configuration of the uplink grant-free PUSCH, the power boost control of OLPC for different TRPs is respectively controlled through the design enhancement of the high-layer signaling and DCI commands, which can solve the interference control when the URLLC service conflicts with the eMBB service and ensure the high reliability of the URLLC service.

[0142] In the open-loop power control method for the uplink unscheduled PUSCH provided by the embodiments of the present disclosure, when associating a single unscheduled PUSCH configuration with power control parameters, the following method can be adopted: association mapping is achieved through the SRI codepoint. In the case of one SRI indication field, the SRI indication information indicated by the SRI codepoint and corresponding to one or more TRPs respectively corresponds to the power control parameters of one or more TRPs associated with a single unscheduled PUSCH configuration. When the GC-DCI indicates the power boost parameters for different TRP controls, the network device can define relevant indication fields in the GC-DCI to respectively indicate the open-loop power boost parameters for multi-TRP transmitted to different TRPs corresponding to the SRI indication, so as to indicate the CG PUSCH transmitted for all configurations of this terminal. When the GC-DCI indicates the power boost parameters for different TRP controls, if there is no SRI indication field in the DCI, there is a predefined association indication relationship between the open-loop power boost parameters of multi-TRP transmitted to different TRPs and the unscheduled PUSCH configuration. In one example, if there is no SRI indication field in the DCI, the default value in the predefined list can be used. For example, the first P0 value in the P0 power parameter list indicated by the corresponding TRP is used.

[0143] In the open-loop power control method for the uplink unscheduled PUSCH provided by the embodiments of the present disclosure, when associating a single unscheduled PUSCH configuration with power control parameters, the following method can be adopted: association mapping is achieved through multiple SRI indication fields. In the case of multiple SRI indication fields, each SRI indication information corresponding to different TRPs respectively corresponds to the power control parameters of one or more TRPs associated with a single unscheduled PUSCH configuration. When the GC-DCI indicates the power boost parameters for different TRP controls, the network device can define relevant indication fields in the GC-DCI to respectively indicate the open-loop power boost parameters for multi-TRP transmitted to different TRPs corresponding to the SRI indication, so as to indicate the CGPUSCH transmitted for all configurations of this terminal. When the GC-DCI indicates the power boost parameters for different TRP controls, if there is no SRI indication field in the DCI, there is a predefined association indication relationship between the open-loop power boost parameters of multi-TRP transmitted to different TRPs and the unscheduled PUSCH configuration. In one example, if there is no SRI indication field in the DCI, the default value in the predefined list can be used. For example, the first P0 value in the P0 power parameter list indicated by the corresponding TRP is used.

[0144] In the open-loop power control method for uplink unscheduled PUSCH provided by the embodiments of the present disclosure, when associating a single unscheduled PUSCH configuration with power control parameters, the following method can be adopted: In the open-loop power control method for uplink unscheduled PUSCH, multiple different sets of power control parameters can also be configured, and the power control parameters of different TRPs are associated through multiple different sets of power control parameters. That is, different sets of power control parameters are configured, and the transmission parameters for different TRPs are respectively mapped through different SRI fields. When the power boost parameters for different TRP controls are indicated by GC-DCI, the network device can respectively indicate the open-loop power boost parameters for multi-TRP transmitted for different TRPs corresponding to the SRI indication by defining relevant indication fields in the GC-DCI, so as to indicate all the configured transmitted CG PUSCHs acting on this terminal. When the power boost parameters for different TRP controls are indicated by GC-DCI, if there is no SRI indication field in the DCI, there is a predefined association indication relationship between the open-loop power boost parameters of multi-TRP transmitted for different TRPs and the unscheduled PUSCH configuration. In one example, if there is no SRI indication field in the DCI, the default value in the predefined used list can be used. For example, the first P0 value in the P0 power parameter list indicated by the corresponding TRP is used.

[0145] In the open-loop power control method for uplink unscheduled PUSCH provided by the embodiments of the present disclosure, when associating a single unscheduled PUSCH configuration with power control parameters, the following method can be adopted: The association mapping is implemented through the SRI codepoint. In the case where there is one SRI indication field, the SRI indication information indicated by the SRI codepoint and corresponding to one or more TRPs respectively corresponds to the power control parameters of one or more TRPs associated with a single unscheduled PUSCH configuration. When the power boost parameters for different TRP controls are indicated by GC-DCI, the network device can define relevant indication fields for each configured resource in the GC-DCI to respectively indicate the open-loop power boost parameters for multi-TRP of different TRPs corresponding to the SRI indication. Among them, this indication only acts on the corresponding CG PUSCH configuration indicated by the base station. When the power boost parameters for different TRP controls are indicated by GC-DCI, if there is no SRI indication field in the DCI, there is a predefined association indication relationship between the open-loop power boost parameters of multi-TRP transmitted for different TRPs and the unscheduled PUSCH configuration. In one example, if there is no SRI indication field in the DCI, the default value in the predefined used list can be used. For example, the first P0 value in the P0 power parameter list indicated by the corresponding TRP is used.

[0146] In the open-loop power control method for uplink unscheduled PUSCH provided by the embodiments of the present disclosure, when associating a single unscheduled PUSCH configuration with power control parameters, the following method can be adopted: The association mapping is achieved through multiple SRI indication fields. In the case of multiple SRI indication fields, through each SRI indication information corresponding to different TRPs, one or more power control parameters of one or more TRPs corresponding to a single unscheduled PUSCH configuration are correspondingly associated. When the power boost parameters for different TRP controls are indicated by GC-DCI, the network device can define relevant indication fields for each configured resource in the GC-DCI to respectively indicate the open-loop power boost parameters for multi-TRP corresponding to different TRPs indicated by the SRI. Among them, this indication only acts on the corresponding CG PUSCH configuration indicated by the base station. When the power boost parameters for different TRP controls are indicated by GC-DCI, if there is no SRI indication field in the DCI, there is a predefined association indication relationship between the open-loop power boost parameters of multi-TRP sent to different TRPs and the unscheduled PUSCH configuration. In one example, if there is no SRI indication field in the DCI, the default value in the predefined list can be used. For example, the first P0 value in the P0 power parameter list indicated by the corresponding TRP is used.

[0147] In the open-loop power control method for uplink unscheduled PUSCH provided by the embodiments of the present disclosure, when associating a single unscheduled PUSCH configuration with power control parameters, the following method can be adopted: In the open-loop power control method for uplink unscheduled PUSCH, multiple different sets of power control parameters can also be configured, and the power control parameters of different TRPs are associated through multiple different sets of power control parameters. That is, different sets of power control parameters are configured, and the transmission parameters for different TRPs are respectively mapped through different SRI fields. When the power boost parameters for different TRP controls are indicated by GC-DCI, the network device can define relevant indication fields for each configured resource in the GC-DCI to respectively indicate the open-loop power boost parameters for multi-TRP corresponding to different TRPs indicated by the SRI. Among them, this indication only acts on the corresponding CG PUSCH configuration indicated by the base station. When the power boost parameters for different TRP controls are indicated by GC-DCI, if there is no SRI indication field in the DCI, there is a predefined association indication relationship between the open-loop power boost parameters of multi-TRP sent to different TRPs and the unscheduled PUSCH configuration. In one example, if there is no SRI indication field in the DCI, the default value in the predefined list can be used. For example, the first P0 value in the P0 power parameter list indicated by the corresponding TRP is used.

[0148] In the open-loop power control method for the uplink unscheduled PUSCH provided by the embodiments of the present disclosure, when associating a single unscheduled PUSCH configuration with power control parameters, the following method can be adopted: Association mapping is achieved through the SRI codepoint. In the case of one SRI indication field, the SRI indication information indicated by the SRI codepoint and corresponding to one or more TRPs respectively corresponds to the power control parameters of one or more TRPs associated with a single unscheduled PUSCH configuration. The network device can indicate the time-frequency resource location where the terminal has a time-frequency resource conflict with other users in the GC-DCI, such as the time-frequency resource location of the eMBB that may conflict with each other. The terminal determines whether it is affected by the time-frequency resource conflict based on the indication information sent by the network device. If the terminal determines that it is affected by the time-frequency resource conflict, the terminal performs power boosting operations for different TRPs respectively.

[0149] In the open-loop power control method for the uplink unscheduled PUSCH provided by the embodiments of the present disclosure, when associating a single unscheduled PUSCH configuration with power control parameters, the following method can be adopted: Association mapping is achieved through multiple SRI indication fields. In the case of multiple SRI indication fields, each SRI indication information corresponding to different TRPs respectively corresponds to the power control parameters of one or more TRPs associated with a single unscheduled PUSCH configuration. The network device can indicate the time-frequency resource location where the terminal has a time-frequency resource conflict with other users in the GC-DCI, such as the time-frequency resource location of the eMBB that may conflict with each other. The terminal determines whether it is affected by the time-frequency resource conflict based on the indication information sent by the network device. If the terminal determines that it is affected by the time-frequency resource conflict, the terminal performs power boosting operations for different TRPs respectively.

[0150] In the open-loop power control method for the uplink unscheduled PUSCH provided by the embodiments of the present disclosure, when associating a single unscheduled PUSCH configuration with power control parameters, the following method can be adopted: In the open-loop power control method for the uplink unscheduled PUSCH, multiple different sets of power control parameters can also be configured, and the power control parameters of different TRPs are associated through multiple different sets of power control parameters. That is, different sets of power control parameters are configured, and the transmission parameters for different TRPs are respectively mapped through different SRI fields. The network device can indicate the time-frequency resource location where the terminal has a time-frequency resource conflict with other users in the GC-DCI, such as the time-frequency resource location of the eMBB that may conflict with each other. The terminal determines whether it is affected by the time-frequency resource conflict based on the indication information sent by the network device. If the terminal determines that it is affected by the time-frequency resource conflict, the terminal performs power boosting operations for different TRPs respectively.

[0151] Based on the same concept, embodiments of the present disclosure also provide an open-loop power control method for unscheduled PUSCH in the uplink. The open-loop power control method for unscheduled PUSCH in the uplink can be executed by a terminal.

[0152] Figure 5 FIG. 4 is a flowchart of an open-loop power control method for unscheduled PUSCH in the uplink shown according to an exemplary embodiment. As Figure 5 shown, the open-loop power control method for unscheduled PUSCH in the uplink includes the following steps.

[0153] In step S41, indication information is received. The indication information is used to indicate the open-loop power boost parameter of the unscheduled PUSCH configuration adopted for single-TRP independent transmission or multi-TRP cooperative transmission of a transport block (TB).

[0154] In step S42, based on the indication information, the open-loop power boost parameter of the unscheduled PUSCH configuration adopted for single-TRP independent transmission or multi-TRP cooperative transmission of a TB is determined.

[0155] In one implementation, the unscheduled PUSCH configuration includes unscheduled PUSCH type 1 and unscheduled PUSCH type 2. For unscheduled PUSCH type 1, uplink authorization is provided by RRC, including activation of the authorization. Once the terminal correctly receives the RRC configuration, the unscheduled PUSCH configuration becomes effective immediately. For unscheduled PUSCH type 2, the RRC provides a transmission period, and the network device realizes resource activation and configuration of some transmission parameters through DCI, so as to realize the activation transmission of this authorization configuration. After receiving the activation command, if there is data to send in the buffer, the terminal will transmit according to a pre-configured period. If there is no data, the terminal will not transmit any data. The PDCCH transmission time determines the activation time. The terminal confirms the activation / deactivation of unscheduled PUSCH type 2 by sending MAC control signaling in the uplink.

[0156] In one implementation, the open-loop power boost parameter is determined based on the open-loop power boost parameters of one or more TRPs. The open-loop power boost parameters of one or more TRPs used to determine the open-loop power boost parameter are configured based on RRC configuration information. Wherein, the RRC configuration information is used to indicate the respective open-loop power boost parameters for the unscheduled PUSCH configuration adopted for single-TRP direction or multiple different TRP directions to transmit a TB.

[0157] In one implementation, the RRC configuration information is used to indicate different open-loop power boost parameters for each of one or more grant-free PUSCH configurations.
