Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a method, device and storage medium for determining an uplink collaborative TRP. Background Art

[0002] With the advancement of communication technology, beam-based transmission and reception are becoming increasingly necessary to ensure coverage. When a network device (such as a base station) has multiple Transmission Reception Points (TRPs), multiple TRPs (Multi-TRPs) / Multi-PANELs can be used to provide services to terminals. The use of multiple TRPs / PANELs in network devices primarily aims to improve coverage at the cell edge and provide more balanced service quality within the service area. Data transmission is coordinated across multiple TRPs / PANELs in various ways. From a network architecture perspective, deploying a network with a large number of distributed access points and centralized baseband processing is more conducive to providing a balanced user experience rate and significantly reducing the latency and signaling overhead associated with handoffs. Leveraging the coordination of multiple TRPs / PANELs and transmitting / receiving channels using multiple beams from multiple angles can better overcome various obstructions and ensure link robustness. This approach is suitable for Ultra Reliable Low Latency Communication (URLLC) services, improving transmission quality and meeting reliability requirements.

[0003] During the R16 research phase, the physical downlink shared channel (PDSCH) was enhanced based on the application of multi-point coordinated transmission technology between downlink multiple TRPs / PANELs. Since data transmission includes scheduling feedback for uplink and downlink channels, enhancing only the downlink data channel in URLLC research cannot guarantee service performance. Therefore, in the R17 research, the downlink control channel (PDCCH), uplink control channel (PUCCH), and uplink shared channel (PUSCH) will continue to be enhanced.

[0004] In the multi-TRP-based uplink enhancement solution, multiple collaborative TRPs in the multi-TRP-oriented uplink transmission are scheduled by the network device and configured to the terminal through a Sounding Reference Signal (SRS) resource set. Each resource set is associated with the transmission of an antenna panel or the transmission direction of a TRP, and each resource is associated with a specific beam direction. PUSCH transmission is performed between the configured collaborative TRPs, and dynamic switching between single-TRP and multi-TRP transmission states is supported.

[0005] In new radio (NR), the collaborative TRP configuration for uplink transmission is a fixed TRP that is semi-statically configured by the network through radio resource control (RRC) signaling. Therefore, if the collaborative TRP needs to be adjusted, RRC reconfiguration is required to achieve it, which limits the flexibility of service transmission and is not conducive to improving the transmission reliability and mobility of uplink services.

[0109] Exemplary embodiments are described in detail herein, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numerals in different drawings represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present disclosure.

[0110] The uplink cooperative TRP determination method provided by the embodiment of the present disclosure can be applied to Figure 1 In the wireless communication system shown in FIG. Figure 1 As shown, the wireless communication system includes a network device 20 and a terminal 10. The terminal connects to the network device via radio resources and performs data transmission. Data transmission between the network device and the terminal is based on beamforming. PUSCH uplink transmission enhancement can be performed between the network device and the terminal based on Multi-TRP.

[0111] It is understandable that the number of TRPs used by the network device to transmit data with the terminal based on Multi-TRP can be one or more. Figure 1 The wireless communication system shown in the figure shows that the network device transmits data with the terminal based on TRP1, TRP2...TRPn for illustrative purposes only and is not intended to be limiting.

[0112] It is understandable that Figure 1 The wireless communication system shown is only for schematic illustration. The wireless communication system may also include other network devices, such as core network devices, wireless relay devices, and wireless backhaul devices. Figure 1 The embodiment of the present disclosure does not limit the number of network devices and terminals included in the wireless communication system.

[0113] It can be further understood that the wireless communication system of the embodiment 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 frequency division multiple access (SC-FDMA), and 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 (English: generation) network, 3G network, 4G network or future evolution network, such as 5G network. 5G network can also be called new radio (NR). For the convenience of description, the present disclosure sometimes refers to the wireless communication network as simply a network.

[0114] Furthermore, the network devices involved in the present disclosure may also be referred to as wireless access network devices. The wireless access network devices may be: base stations, evolved node Bs (base stations), home base stations, access points (APs) in wireless fidelity (WIFI) systems, wireless relay nodes, wireless backhaul nodes, transmission points (TPs) or transmission and reception points (TRPs), etc. They may also be gNBs in NR systems, or they may be components or part of devices that constitute base stations. It should be understood that in the embodiments of the present disclosure, the specific technologies and specific device forms used by the network devices are not limited. In the present disclosure, the network devices 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 devices may also be vehicle-mounted devices.

[0115] Furthermore, the terminal involved in the present disclosure may also be referred to as a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., which is a device that provides voice and / or data connectivity to users. For example, the terminal can be a handheld device with wireless connection function, a vehicle-mounted device, etc. At present, some examples of terminals are: smart phones (Mobile Phones), customer premises equipment (Customer Premise Equipment, CPE), pocket computers (Pocket Personal Computers, PPCs), handheld computers, personal digital assistants (Personal Digital Assistants, PDAs), laptops, tablet computers, wearable devices, or vehicle-mounted devices, 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 embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal.

[0116] In the present disclosure, data transmission between the network device and the terminal is based on beams. Among them, the network device and the terminal can enhance uplink transmission based on Multi-TRP, that is, the terminal can adopt multi-point cooperative transmission technology for uplink transmission enhancement in the direction of multiple TRP transmissions. The multiple TRPs that cooperate in the uplink transmission based on the multi-TRP transmission direction are configured to the terminal through the SRS resource set after network scheduling. Each SRS resource set is associated with the transmission of an antenna panel or the transmission direction of a TRP, and each resource is associated with a specific beam direction. For example, the transmission of PUSCH can be carried out between the configured cooperative TRP directions, and the dynamic switching of single TRP and multi-TRP transmission states is supported.

[0117] In related technologies, the cooperative TRP transmission direction for uplink transmission is semi-statically configured by the network through RRC signaling. Therefore, if the cooperative TRP needs to be adjusted, RRC reconfiguration is required. This mechanism of semi-statically configuring the cooperative TRP transmission direction limits the flexibility of service transmission and is not conducive to improving the transmission reliability and mobility of uplink services.

[0118] An embodiment of the present disclosure provides an uplink collaborative TRP determination method that can realize dynamic uplink collaborative TRP sending direction selection. In this method, the network device can configure and determine one or more TRP sending directions based on one or more SRS resource sets, and then determine the collaborative TRP sending direction of the terminal to collaboratively send PUSCH towards multiple TRP sending directions based on the one or more TRP sending directions.

[0119] Figure 2 FIG. 1 is a flow chart of a method for determining an uplink cooperative TRP according to an exemplary embodiment. The method for determining an uplink cooperative TRP can be performed alone or in combination with other embodiments of the present disclosure. Figure 2 As shown, the uplink collaborative TRP determination method is executed by the network device and includes the following steps.

[0120] In step S11, one or more SRS resource sets are determined.

[0121] In the embodiment of the present disclosure, the SRS resource set may be configured by a network device to a terminal.

[0122] In step S12, one or more TRP sending directions are configured and determined based on one or more SRS resource sets.

[0123] Among them, the configured and determined one or more TRP sending directions are used to determine the collaborative TRP. The collaborative TRP can be understood as the TRP used by the terminal to send PUSCH in multiple TRP directions.

[0124] In an embodiment of the present disclosure, based on one or more SRS resource sets, one or more TRP sending directions are configured and determined to determine the collaborative TRP sending direction in which the terminal collaboratively sends PUSCH towards multiple TRP sending directions, thereby realizing dynamic uplink collaborative TRP selection.

[0125] In the embodiment of the present disclosure, when determining the sending direction of the dynamic collaborative TRP, it can be based on network device scheduling on the one hand, and on the other hand, it can also be selected based on the terminal.

[0126] The following first describes the process of determining the sending direction of dynamic collaborative TRP based on network device scheduling.

[0127] In one implementation, the embodiment of the present disclosure may configure multiple SRS resource sets through higher layer signaling, for example, through RRC signaling.

[0128] Figure 3 FIG. 1 is a flow chart of a method for determining an uplink cooperative TRP according to an exemplary embodiment. The method for determining an uplink cooperative TRP can be performed alone or in combination with other embodiments of the present disclosure. Figure 3 As shown, the uplink collaborative TRP determination method is executed by the network device and includes the following steps.

[0129] In step S21, multiple SRS resource sets are configured through higher layer signaling.

[0130] Among them, each SRS resource set in the multiple SRS resource sets configured by the network device through high-level signaling is associated with a different terminal panel or a different TRP sending direction.

[0131] In the embodiment of the present disclosure, one SRS resource set is associated with one terminal panel or one TRP sending direction, and different SRS resource sets are associated with different panels and / or are associated with different TRP sending directions.

[0132] In the related art, uplink transmission schemes include codebook-based uplink transmission and non-codebook uplink transmission. In the embodiments of the present disclosure, the multiple SRS resource sets that can be configured by high-layer signaling can be SRS resource sets based on codebook transmission or SRS resource sets based on non-codebook transmission.

[0133] On the one hand, the network equipment configures multiple SRS resource sets based on codebook transmission through high-level signaling, and each SRS resource in the SRS resource set based on codebook transmission is configured with corresponding TRP sending direction indication information, that is, each SRS resource in the SRS resource set based on codebook transmission corresponds to a different terminal antenna panel or a different TRP sending direction.

[0134] The TRP transmission direction indication information can be understood as the specific spatial beam indication information under the TRP direction. There can be multiple different spatial beams under the same TRP transmission direction. For example, SRS resource set #1 is associated with the TRP1 transmission direction. For resource 1 in SRS resource set #1, the TRP transmission direction indication information corresponding to resource 1 can be beam 1 in the TRP1 transmission direction, and the TRP transmission direction indication information corresponding to resource 2 can be beam 2 in the TRP1 transmission direction.

[0135] In one example, a network device can configure multiple codebook-based SRS resource sets through RRC, corresponding to different terminal antenna panels or different TRP transmission directions. For codebook-based transmission, an SRS resource set with the function "codebook" can be configured with multiple SRS resources, each of which is configured with a fixed beam direction (spatial relation info).

[0136] On the other hand, for uplink transmission based on non-codebook, an SRS resource set with the function of "non-codebook" can be configured with multiple SRS resources, each of which can be configured with a specific beam direction (spatial relation info) or a channel state information (CSI) reference signal (CSI Reference Signal, CSI-RS) associated with a certain TRP. In the embodiment of the present disclosure, the network device configures multiple SRS resource sets based on non-codebook transmission through high-layer signaling, and each SRS resource in the SRS resource set based on non-codebook transmission is configured with corresponding TRP sending direction indication information, or is configured with a CSI-RS associated with the corresponding TRP.

[0137] Among them, CSI-RS is associated with TRP, so when CSI-RS is configured, the TRP associated with CSI-RS can be determined, and there is no need to configure the TRP sending direction indication information. It can be understood that the TRP sending direction indication information and the CSI-RS associated with TRP are configured in an alternative manner and cannot be configured at the same time.

[0138] In an embodiment of the present disclosure, the network device can activate different combinations of one or more configured SRS resource sets as collaborative TRP sending directions for the terminal to collaboratively send PUSCH towards multiple TRP sending directions.

[0139] In one embodiment, the network device can activate the SRS resource set of the collaborative TRP sending direction for collaboratively sending PUSCH as a terminal to multiple TRP sending directions through indication information. The indication information indicating the SRS resource set of the collaborative TRP sending direction for collaboratively sending PUSCH as a terminal to multiple TRP sending directions is referred to as the first indication information below.

[0140] Figure 4 According to a flowchart of an uplink cooperative TRP determination method shown in an exemplary embodiment, the uplink cooperative TRP determination method can be executed alone or in combination with other embodiments of the present disclosure. Figure 4 It is shown that the uplink collaborative TRP determination method is executed by the network device and includes the following steps.

[0141] In step S31, multiple SRS resource sets are configured through higher layer signaling.

[0142] Among them, each SRS resource set in the multiple SRS resource sets configured by the network device through high-level signaling is associated with a different terminal panel or a different TRP sending direction.

[0143] In step S32, first indication information is sent, where the first indication information is used to indicate part or all of the SRS resource sets in the plurality of SRS resource sets.

[0144] Among them, in the embodiment of the present disclosure, the network device can activate part or all of the multiple SRS resource sets for the terminal through the first indication information based on known information, such as new measurements, or reciprocity, etc. The TRP sending direction associated with the part or all of the SRS resource sets activated by the terminal is used as the collaborative TRP sending direction for the terminal to collaboratively send PUSCH towards multiple TRP sending directions.

[0145] In one example, a network device is configured with four SRS resource sets #1-#4. Each of these SRS resource sets is associated with a different TRP transmission direction. For example, SRS resource set #1 is associated with the TRP1 transmission direction, SRS resource set #2 is associated with the TRP2 transmission direction, SRS resource set #3 is associated with the TRP3 transmission direction, and SRS resource set #4 is associated with the TRP4 transmission direction. If the first indication information indicates SRS resource set #1 and SRS resource set #13, it can be determined that the terminal transmits a PUSCH in the TRP1 transmission direction and the TRP2 transmission direction.

[0146] In the embodiment of the present disclosure, a default TRP sending direction can also be set to activate some or all of the multiple SRS resource sets. This can be done by indicating update information relative to the default TRP sending direction to activate some or all of the multiple SRS resource sets, which serve as a collaborative TRP sending direction for the terminal to collaboratively send PUSCH towards multiple TRP sending directions.

[0147] In one implementation of the embodiment of the present disclosure, the first indication information may be an activation command carried in a Medium Access Control (MAC)-control element (CE).

[0148] In the embodiment of the present disclosure, when activating part or all of the multiple SRS resource sets through MAC-CE, each SRS resource set can be activated by independent indication, or by joint indication.

[0149] For the independent indication mode, the first indication information includes multiple indication information carried in the MAC-CE signaling, and each indication information in the multiple indication information corresponds to an SRS resource set. For example, if there are four SRS resource sets #1-#4 configured as the "codebook" function, and SRS resource set #1 and SRS resource set #3 are used as collaborative TRP sending directions for the terminal to collaboratively send PUSCH to multiple TRP sending directions, then SRS resource set #1 and SRS resource set #3 are activated respectively as collaborative TRP sending directions for the terminal to collaboratively send PUSCH to multiple TRP sending directions.

[0150] For the joint indication method, the first indication information includes an indication information carried in MAC-CE signaling, where the indication information corresponds to multiple SRS resource sets. For example, the activation status of the SRS resource sets is jointly indicated through network preconfigured or predefined indication information. Based on the above example, for example, the activation of SRS resource set #1 and SRS resource set #3 among SRS resource sets #1-#4 can be indicated by codepoint.

[0151] In another implementation of the disclosed embodiment, the network device may configure and associate multiple TRP sending directions with the SRS resources in the SRS resource set configuration that supports PUSCH collaborative transmission of multiple TRPs defined in the current protocol, so that the terminal can dynamically select the collaborative TRP sending direction.

[0152] Among them, the SRS resource set supporting PUSCH collaborative transmission of multiple TRPs defined in the above protocol can be an SRS resource set configuration that supports two TRPs and configures two SRS resource sets.

[0153] Figure 5 According to a flowchart of an uplink cooperative TRP determination method shown in an exemplary embodiment, the uplink cooperative TRP determination method can be executed alone or in combination with other embodiments of the present disclosure. Figure 5 It is shown that the uplink collaborative TRP determination method is executed by the network device and includes the following steps.

[0154] In step S41, an SRS resource set for collaboratively transmitting PUSCH in multiple TRP transmission directions is configured, and each SRS resource configuration in the SRS resource set is associated with multiple TRP transmission directions.

[0155] In one example, the network device is configured with SRS resource set 1 and / or SRS resource set 2. SRS resource set 1 includes resource 1, resource 2...resource n. SRS resource set 2 includes resource 1, resource 2...resource m. Among them, m and n are positive integers, and can be the same or different. In the embodiment of the present disclosure, the associated TRP sending directions can be configured for resource 1, resource 2...resource n included in SRS resource set 1 respectively. For example, resource 1 is associated with TRP1 sending direction and TRP2 sending direction, resource 2 is associated with TRP3 sending direction and TRP4 sending direction,...resource n is associated with TRPx sending direction and TRPy sending direction. The implementation scheme for associating multiple TRP sending directions for the configuration of resource 1, resource 2...resource m included in SRS resource set 2 is similar.

[0156] Among them, a TRP sending direction may include multiple different spatial beam information, such as spatialrelation info.

[0157] In the embodiment of the present disclosure, multiple spatial relation info may be associated with each SRS resource in the SRS resource set, or a group of spatial relation info may be defined, each corresponding to a different panel or TRP sending direction.

[0158] In one implementation of the disclosed embodiments, for codebook-based transmission, that is, when the SRS resource set is an SRS resource set for codebook-based transmission, each SRS resource in the SRS resource set for codebook-based transmission is configured with multiple TRP transmission directions. In other words, an SRS resource set with a "codebook" function can be configured with multiple SRS resources, each of which is configured with multiple fixed beam direction spatial relation info.

[0159] In another implementation of the disclosed embodiment, for non-codebook-based transmission, that is, when the SRS resource set is an SRS resource set based on non-codebook transmission, each SRS resource in the SRS resource set based on non-codebook transmission is configured with multiple TRP sending directions, or is configured with multiple CSI-RS associated with corresponding multiple TRPs. That is, for non-codebook-based transmission, an SRS resource set with the function of "non-codebook" can be configured with multiple SRS resources, and each SRS resource can be configured with multiple specific beam direction spatial relation info, and can also be configured with multiple CSI-RS associated with a specific TRP. However, spatial relation info and TRP-associated CSI-RS cannot be configured at the same time.

[0160] In an embodiment of the present disclosure, the network device can activate a TRP sending direction among multiple TRP sending directions associated with SRS resources as a collaborative TRP sending direction for the terminal to collaboratively send PUSCH to multiple TRP sending directions.

[0161] In one embodiment, the network device can activate the TRP transmission direction as a collaborative TRP transmission direction for collaboratively transmitting PUSCH to multiple TRP transmission directions as a terminal through indication information. hereinafter, the indication information indicating the TRP transmission direction as a collaborative TRP transmission direction for collaboratively transmitting PUSCH to multiple TRP transmission directions as a terminal is referred to as second indication information.

[0162] Figure 6 According to a flowchart of an uplink cooperative TRP determination method shown in an exemplary embodiment, the uplink cooperative TRP determination method can be executed alone or in combination with other embodiments of the present disclosure. Figure 6 It is shown that the uplink collaborative TRP determination method is executed by the network device and includes the following steps.

[0163] In step S51, an SRS resource set for collaboratively transmitting PUSCH in multiple TRP transmission directions is configured, and each SRS resource configuration in the SRS resource set is associated with multiple TRP transmission directions.

[0164] In step S52, second indication information is sent, where the second indication information is used to indicate some or all of the multiple TRP sending directions associated with the SRS resource.

[0165] In the embodiment of the present disclosure, the second indication information can indicate some or all of the multiple TRP sending directions associated with the SRS resources as collaborative TRP sending directions for the terminal to collaboratively send PUSCH towards the multiple TRP sending directions.

[0166] Based on the above example, if resource 1 included in SRS resource set 1 is associated with the TRP1 and TRP2 transmission directions, resource 2 is associated with the TRP3 and TRP4 transmission directions, ... resource n is associated with the TRPx and TRPy transmission directions, then the second indication information may activate the TRP1, TRP3, and TRPx transmission directions. The terminal transmits the PUSCH in a collaborative manner in the TRP1, TRP3, and TRPx transmission directions.

[0167] Among them, in the embodiment of the present disclosure, the network device can activate some or all of the multiple TRP sending directions associated with the SRS resources for the terminal through the second indication information based on known information, as collaborative TRP sending directions for the terminal to collaboratively send PUSCH to multiple TRP sending directions.

[0168] In one implementation of the embodiment of the present disclosure, the second indication information may be an activation command carried in the MAC-CE.

[0169] In the embodiment of the present disclosure, when some or all of the multiple TRP sending directions associated with SRS resources are activated through MAC-CE, on the one hand, each TRP sending direction can be activated by independent indication, or on the other hand, each TRP sending direction can be activated by joint indication.

[0170] For the implementation scheme of independently indicating each TRP transmission direction, the beam information corresponding to each SRS resource in each resource set is independently indicated. That is, the second indication information includes multiple indication information carried in the MAC-CE signaling, and each indication information in the multiple indication information corresponds to a TRP transmission direction.

[0171] For the joint indication of each TRP sending direction, the direction information (CB) of multiple resources in the resource set can be jointly indicated by the spatial relation info codepoint, or the resource direction information combination (NCB) corresponding to different resource sets can be jointly indicated. That is, the second indication information includes an indication information carried in the MAC-CE signaling, and the one indication information corresponds to multiple TRP sending directions.

[0172] In the embodiment of the present disclosure, the above-mentioned method based on network device configuration and activation realizes an implementation plan for configuring the terminal to collaboratively send PUSCH in multiple TRP sending directions, which facilitates the terminal to dynamically select the collaborative TRP sending direction.

[0173] In the embodiment of the present disclosure, the implementation scheme of the collaborative TRP sending direction in which the terminal selects to collaboratively send PUSCH towards multiple TRP sending directions will be described below.

[0174] In the embodiment of the present disclosure, one or more SRS resource sets may be configured by the network device, and the terminal may determine the collaborative TRP transmission direction for collaboratively transmitting PUSCH towards multiple TRP transmission directions. Alternatively, multiple TRP transmission directions may be associated with each SRS resource in the SRS resource set defined by the network device configuration protocol, and the terminal may determine the collaborative TRP transmission direction for collaboratively transmitting PUSCH towards multiple TRP transmission directions.

[0175] Among them, when the terminal determines the collaborative TRP sending direction, it can determine the collaborative TRP sending direction used for collaboratively sending PUSCH to multiple TRP sending directions based on factors such as path loss / MPE.

[0176] In an embodiment of the present disclosure, after the terminal determines the collaborative TRP sending direction to be used, it can report all or part of the determined collaborative TRP sending direction to the network device to facilitate the network device to perform communication coordination configuration.

[0177] Furthermore, in an embodiment of the present disclosure, when reporting all or part of the collaborative TRP sending directions used, the terminal may report update information relative to the default TRP sending direction.

[0178] Based on the same concept, an embodiment of the present disclosure also provides an uplink collaborative TRP determination method performed by a terminal.

[0179] Figure 7 According to a flowchart of an uplink cooperative TRP determination method shown in an exemplary embodiment, the uplink cooperative TRP determination method can be executed alone or in combination with other embodiments of the present disclosure. Figure 7 It is shown that the uplink collaborative TRP determination method is executed by the terminal and includes the following steps.

[0180] In step S61, based on one or more SRS resource sets, a collaborative TRP is determined. The collaborative TRP is the TRP used by the terminal to send PUSCH in multiple TRP directions.

[0181] In the embodiment of the present disclosure, the SRS resource set for the terminal to determine the collaborative TRP sending direction for collaboratively sending PUSCH towards multiple TRP sending directions can, on the one hand, be multiple SRS resource sets configured by the network device through high-layer signaling, and each SRS resource set in the multiple SRS resource sets is associated with a different terminal panel or a different TRP sending direction. On the other hand, it can also be an SRS resource set configured for collaboratively sending PUSCH towards multiple TRP sending directions, and each SRS resource configuration in the SRS resource set is associated with multiple TRP sending directions.

[0182] Among them, when the terminal determines the collaborative TRP sending direction for collaboratively sending PUSCH to multiple TRP sending directions based on multiple SRS resource sets associated with different terminal panels or different TRP sending directions configured by the network device, it can be based on the activation instruction (first indication information) that some or all of the multiple SRS resource sets in the multiple SRS resource sets serve as the collaborative TRP sending direction for the terminal to collaboratively send PUSCH to multiple TRP sending directions.

[0183] Figure 8 According to a flowchart of an uplink cooperative TRP determination method shown in an exemplary embodiment, the uplink cooperative TRP determination method can be executed alone or in combination with other embodiments of the present disclosure. Figure 8 It is shown that the uplink collaborative TRP determination method is executed by the terminal and includes the following steps.

[0184] In step S71, multiple SRS resource sets are determined through high-layer signaling, and each SRS resource set in the multiple SRS resource sets is associated with a different terminal panel or a different TRP sending direction.

[0185] In step S72, first indication information is obtained, and based on the first indication information, the terminal panel or TRP sending direction associated with some or all of the SRS resource sets in the multiple SRS resource sets is used as the collaborative TRP sending direction for the terminal to collaboratively send PUSCH towards multiple TRP sending directions.

[0186] In one implementation of the disclosed embodiment, the high-level signaling for the terminal to determine multiple SRS resource sets may be RRC signaling, and the first indication information may be an activation instruction carried in MAC-CE signaling. That is, the terminal may use RRC+MAC-CE to send collaborative TRP transmission directions of PUSCH using different combinations of SRS resource sets as multiple TRPs.

[0187] In one embodiment, in the embodiment of the present disclosure, when the first indication information is an activation instruction carried in MAC-CE signaling, on the one hand, it may include multiple indication information carried in MAC-CE signaling, each of the multiple indication information corresponds to an SRS resource set, that is, the terminal determines the collaborative TRP sending direction through multiple indication information of independent indication. Or on the other hand, the first indication information includes one indication information carried in MAC-CE signaling, and the one indication information corresponds to multiple SRS resource sets, that is, the terminal determines the collaborative TRP sending direction through multiple indication information of joint indication.

[0188] In the embodiment of the present disclosure, the terminal can also determine the terminal panel or TRP sending direction associated with some or all of the SRS resource sets in multiple SRS resource sets configured through high-level signaling based on preset rule information (factors such as path loss / MPE), and use it as a collaborative TRP sending direction for the terminal to collaboratively send PUSCH towards multiple TRP sending directions.

[0189] Figure 9According to a flowchart of an uplink cooperative TRP determination method shown in an exemplary embodiment, the uplink cooperative TRP determination method can be executed alone or in combination with other embodiments of the present disclosure. Figure 9 It is shown that the uplink collaborative TRP determination method is executed by the terminal and includes the following steps.

[0190] In step S81, multiple SRS resource sets are determined through high-layer signaling, and each SRS resource set in the multiple SRS resource sets corresponds to a different terminal panel or a different TRP sending direction.

[0191] In step S82, according to the preset rule information, the terminal panel or TRP sending direction associated with some or all of the SRS resource sets is selected from multiple SRS resource sets as the collaborative TRP sending direction for the terminal to collaboratively send PUSCH towards multiple TRP sending directions.

[0192] In the embodiment of the present disclosure, the terminal can select terminal panels or TRP sending directions associated with some or all of the SRS resource sets from multiple SRS resource sets based on multiple SRS resource sets associated with different terminal panels or different TRP sending directions configured by the network device, and based on preset rule information related to factors such as path loss / MPE, as collaborative TRP sending directions for the terminal to collaboratively send PUSCH to multiple TRP sending directions.

[0193] It can be understood that the present disclosure is an embodiment, and in one implementation mode, the multiple SRS resource sets determined by the terminal through high-layer signaling can, on the one hand, be SRS resource sets based on codebook transmission, and each SRS resource in the SRS resource set based on codebook transmission is configured with corresponding TRP transmission direction indication information, that is, each SRS resource in the SRS resource set based on codebook transmission corresponds to a different terminal antenna panel or a different TRP transmission direction. On the other hand, it can also be multiple SRS resource sets based on non-codebook transmission, and each SRS resource in the SRS resource set based on non-codebook transmission is configured with corresponding TRP transmission direction indication information, or is configured with a CSI-RS associated with the corresponding TRP.

[0194] In another embodiment of the present disclosure, the terminal determines the collaborative TRP sending direction for collaboratively sending PUSCH towards multiple TRP sending directions based on the multiple TRP sending directions associated with each SRS resource in the SRS resource set for collaboratively sending PUSCH towards multiple TRP sending directions.

[0195] Figure 10According to a flowchart of an uplink cooperative TRP determination method shown in an exemplary embodiment, the uplink cooperative TRP determination method can be executed alone or in combination with other embodiments of the present disclosure. Figure 10 It is shown that the uplink collaborative TRP determination method is executed by the terminal and includes the following steps.

[0196] In step S91, an SRS resource set for collaboratively transmitting PUSCH in multiple TRP transmission directions is determined, and each SRS resource in the SRS resource set is associated with multiple TRP transmission directions.

[0197] In step S92, the second indication information is obtained, and based on the second indication information, some or all of the multiple TRP sending directions associated with the SRS resource are used as collaborative TRP sending directions for the terminal to collaboratively send PUSCH to multiple TRP sending directions.

[0198] In the embodiment of the present disclosure, the second indication information may be an activation command carried in the MAC-CE.

[0199] In one embodiment, the second indication information includes multiple indication information carried in the MAC-CE signaling, and each indication information in the multiple indication information corresponds to a TRP sending direction. That is, the terminal determines the collaborative TRP sending direction for the terminal to collaboratively send PUSCH towards multiple TRP sending directions through each TRP sending direction independently indicated by the network device. Or on the other hand, the second indication information includes one indication information carried in the MAC-CE signaling, and one indication information corresponds to multiple TRP sending directions. That is, the terminal activates the indication information of each TRP sending direction by means of joint indication of the network device, and determines the collaborative TRP sending direction for the terminal to collaboratively send PUSCH towards multiple TRP sending directions.

[0200] In the embodiment of the present disclosure, the terminal may also select some or all of the collaborative TRP sending directions from the multiple TRP sending directions associated with the SRS resource based on preset rule information (factors such as path loss / MPE), as the collaborative TRP sending direction for the terminal to collaboratively send PUSCH to multiple TRP sending directions.

[0201] Figure 11 According to a flowchart of an uplink cooperative TRP determination method shown in an exemplary embodiment, the uplink cooperative TRP determination method can be executed alone or in combination with other embodiments of the present disclosure. Figure 11 It is shown that the uplink collaborative TRP determination method is executed by the terminal and includes the following steps.

[0202] In step S101, an SRS resource set for collaboratively transmitting PUSCH in multiple TRP transmission directions is determined, and each SRS resource in the SRS resource set is associated with multiple TRP transmission directions.

[0203] In step S102, according to the preset rule information, some or all of the collaborative TRP sending directions are selected from the multiple TRP sending directions associated with the SRS resources as the collaborative TRP sending directions for the terminal to collaboratively send PUSCH towards multiple TRP sending directions.

[0204] In an embodiment of the present disclosure, the terminal can select some or all of the collaborative TRP sending directions from the multiple TRP sending directions associated with the SRS resources based on preset rule information related to factors such as path loss / MPE, as the collaborative TRP sending directions for the terminal to collaboratively send PUSCH to multiple TRP sending directions.

[0205] Furthermore, in the embodiment of the present disclosure, the SRS resource set for collaboratively transmitting PUSCH in multiple TRP transmission directions may be an SRS resource set based on codebook transmission. Each SRS resource in the SRS resource set based on codebook transmission is configured with corresponding multiple TRP transmission direction indication information. In the embodiment of the present disclosure, the SRS resource set for collaboratively transmitting PUSCH in multiple TRP transmission directions may also be an SRS resource set based on non-codebook transmission. Each SRS resource in the SRS resource set based on non-codebook transmission is configured with corresponding multiple TRP transmission direction indication information, or is configured with multiple CSI-RS associated with the corresponding TRP.

[0206] In an embodiment of the present disclosure, after the terminal determines the collaborative TRP sending direction to be used, it can report all or part of the determined collaborative TRP sending direction to the network device to facilitate the network device to perform communication coordination configuration.

[0207] The uplink collaborative TRP determination method provided by the embodiment of the present disclosure realizes the configuration and update of the collaborative TRP under the Multi-TRP configuration, and is used to adapt to the downlink TRP changes or collaborative TRP changes caused by other reasons such as MPC of terminal mobility, so as to better support changes in transmission scenarios and improve transmission reliability.
