[0183] Figure 1aFig. 1 is a schematic diagram of a communication system 100 according to an embodiment of the present disclosure. The communication system 100 can include a terminal device 10, an access network device 20, and a core network device 30.

[0184] The terminal device 10 can refer to a user equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, a remote terminal, a mobile device, a wireless communication device, a user agent, or a user device.

For the convenience of description, the above-mentioned devices are collectively referred to as terminal devices. The number of terminal devices 10 is usually more than one, and one or more terminal devices 10 can be distributed in a cell managed by each access network device 20. In the present disclosure, the terminal device can be referred to as a terminal for short.

[0185] The access network device 20 is a device deployed in an access network to provide wireless communication functions for the terminal device 10. The access network device 20 can include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems using different wireless access technologies, the names of devices with access network device functions can be different, for example, in a 5th Generation New Radio (5G NR) system, it is called a next-generation base station (gNodeB, gNB). As communication technology evolves, the name of the "access network device" can change. For ease of description, in the embodiments of the present disclosure, the above-mentioned devices that provide wireless communication functions for the terminal device 10 are collectively referred to as access network devices 20. Optionally, through the access network device 20, a communication relationship can be established between the terminal device 10 and the core network device 30. Exemplarily, in a Long Term Evolution (LTE) system, the access network device 20 can be an Evolved Universal Terrestrial Radio Access Network (EUTRAN) or one or more evolved base stations in the EUTRAN; in a 5G NR system, the access network device 20 can be a Radio Access Network (RAN) or one or more gNBs in the RAN.

[0186] The core network device 30 is a device deployed in a core network, and the functions of the core network device 30 mainly include providing user connection, managing users, and completing bearer for services, and providing an interface to an external network as a bearer network. For example, the core network device in a 5G NR system includes an Access and Mobility Management Function (AMF) network element, a User Plane Function (UPF) network element, and a Session Management Function (SMF) network element.

[0187] In some embodiments, the network device 20 can include an access network device.

[0190] In some embodiments, the access network device 20 and the core network device 30 communicate with each other through an air interface, such as the NG interface in the 5G NR system. The access network device 20 and the terminal device 10 communicate with each other through an air interface, such as the Uu interface.

[0191] The following embodiments of the present disclosure can be applied to Figure 1a The communication system 100 or part of the main body shown is applicable, but is not limited thereto. Figure 1a The main body shown is an example, the communication system 100 can include all or part of the main body in FIG. 1, or can include Figure 1a other main bodies, the number of each main body is arbitrary, the connection relationship between each main body is an example, each main body can not be connected or can be connected, the connection can be any way, can be direct connection or indirect connection, can be wired connection or wireless connection. In addition, the name of the communication system 100 and each main body is not limited.

[0192] Figure 1b is a schematic diagram of a communication system according to an embodiment of the present disclosure, which can include a terminal device 10 and a network device 20, the network device 20 including a TRP1, a TRP2.

[0193] There are two communication scenarios between the terminal device 10 and the network device 20: uplink communication scenario and downlink communication scenario. Among them, the uplink communication refers to the terminal device 10 sending signals to the network device 20; the downlink communication refers to the network device 20 sending signals to the terminal device 10.

[0194] In some embodiments of the present disclosure, the Multi-TRP (M-TRP) scenario is not considered, the uplink is single TRP transmission, in some embodiments of the present disclosure, the M-TRP uplink transmission under single downlink control information (S-DCI) is enhanced, the physical uplink shared channel (PUSCH) transmission is transmitted to multiple TRPs, in some embodiments of the present disclosure, the main standardization is the cooperative transmission under the time division multiplexing (TDM) transmission mode, through the different transmission occasions (TO) of time domain, the repeated transmission of the same information of PUSCH is sent to different TRPs in time, this method has lower requirements on terminal capability, does not require to support the capability of sending beams at the same time, and has larger transmission delay. For example Figure 1bAs shown, the terminal is directly or indirectly scheduled by one Downlink Control Information (DCI) with a precoding matrix 1 and a precoding matrix 2. The terminal device 10 uses the panel 1 to transmit one or more layers of uplink data to the TRP 1 based on the precoding matrix 1. The terminal device 10 uses the panel 2 to transmit one or more layers of uplink data to the TRP 1 based on the precoding matrix 2.

[0195] The above-mentioned TRP 1 and TRP 2 can be two TRPs of the same cell, or two TRPs of different cells.

[0196] In actual deployment, the link between the TRPs can be an ideal backhaul link supporting high throughput and very low backhaul delay, or a non-ideal backhaul link using x Digital Subscriber Line (xDSL), microwave, relay, etc. The M-DCI based Non-Coherent Joint Transmission (NC-JT) transmission scheme is mainly for non-ideal backhaul links, but this scheme can also be used for ideal backhaul links.

[0197] The terminal is generally configured with multiple antenna panels, and the capabilities of different antenna panels can also be different, such as different SRS port numbers, and the maximum number of data transmission layers supported can also not be the same, such as one panel supporting a maximum of 2-layer transmission and another panel supporting a maximum of 4-layer transmission. The network scheduler will determine whether the terminal is currently suitable for multi-panel uplink simultaneous transmission, and if the terminal is currently suitable for multi-panel uplink simultaneous transmission and is scheduled, the network device will directly or indirectly indicate the relevant transmission parameters, including terminal specific beam indication information, data layer number used for transmission, DeModulation Reference Signal (DMRS) port allocation, and precoding indication information, etc.

[0198] For example, in the STxMP scenario, the multi-antenna precoding of PUSCH supports two different mode configurations, one is codebook-based transmission and the other is non-codebook-based transmission. Generally, whether the reciprocity of uplink and downlink channels is established is used to select the use mode. Both precoding modes require the terminal to send SRS for the base station to estimate the uplink Channel State Information (CSI).

[0199] (1) Codebook-based transmission:

[0200] In codebook-based transmission, the terminal needs to be configured with at most one SRS resource set for codebook-based uplink transmission, and the SRS resource set can be configured with multiple SRS resources. The network device side will feed back The SRS resource indication (SRI) indicates the selection of SRS resources through the SRI, and finally the network device determines the transmission precoding matrix indicator (TPMI) and the transmission rank indicator (TRI) used by the terminal for actual transmission based on the measurement of uplink CSI and notifies the terminal. The terminal needs to use the TPMI and TRI specified by the network device for precoding in the data of the next uplink transmission, and the precoded data is mapped to the corresponding antenna port according to the spatial filter corresponding to the SRS resource indicated by the SRI. Different SRSs use different spatial filters for transmission, so the precoded data of the terminal needs to be filtered by the spatial filter used by the SRS indicated by the SRI. In this way, data transmission from single layer to full rank can be supported.

[0201] Figure 1c A schematic diagram of a codebook-based uplink transmission process provided by an example embodiment of the present disclosure is shown, which is executed by the terminal device 10 and the network device 20 described above.

[0202] In the codebook-based uplink transmission process, the network device 20 first sends an SRS resource configuration to the terminal device 10, the SRS resource configuration including at least one SRS resource and the time-frequency resource location of each SRS resource, and then the terminal device 10 sends at least one SRS to the network device 20 based on the SRS resource configuration, the network device 20 obtains the channel conditions of each uplink channel based on the received at least one SRS, and then provides a DCI to the terminal device 10, the DCI including at least SRI and TPMI, and finally the terminal device 10 sends PUSCH to the network device 20 based on SRI and TPMI.

[0203] The indication method of SRI for multiple SRS resources is given in Table 1. Table 2 gives the signaling indication method of TPMI and TRI for single-layer transmission with 4 antenna ports, respectively, for different UE capabilities. Here, the UE capability is divided into three types: full correlation, partial correlation and no correlation, which represents the correlation capability of the antenna port. Table 3 corresponds to the code word for single-layer transmission with 4 antenna ports.

[0210] Not all terminals can calibrate all antenna ports to be coherently transmissible. The codebook design of uplink transmission needs to consider the antenna coherent transmission capability of the terminal. The NR system defines three kinds of antenna coherent transmission capabilities of the terminal:

[0211] ① Full Coherent: all antennas of the terminal can be coherently transmissible;

[0212] ② Partial Coherent: the antennas within the same coherent transmission pair of the terminal can be coherently transmissible, and the antennas between different coherent transmission pairs cannot be coherently transmissible;

[0213] ③ Non-coherent: the terminal has no antenna that can be coherently transmissible.

[0214] The NR system allows the network device to configure the terminal with a maximum of 2 SRS resources for channel sounding based on codebook uplink transmission. The 2 SRS resources contain the same number of SRS antenna ports and have the same time domain type, i.e., both SRS resources are periodic SRS or semi-persistent SRS or aperiodic SRS. The NR system does not support the network device indicating multiple SRS resources for codebook-based uplink transmission to the terminal. When the network device configures the terminal with 2 SRS resources for codebook-based uplink transmission, the network device indicates one SRS resource corresponding to TPMI / TRI to the terminal through SRI.

[0215] (2) Non-codebook-based transmission:

[0216] For non-codebook-based uplink transmission, the terminal sends the network device a capability of the maximum number of SRS resources that can be simultaneously transmitted. When the network device performs SRI indication to the terminal at slot n, the corresponding SRS resource transmission is the latest SRS transmission before slot n.

[0217] The terminal determines the limit of precoding indication according to the maximum rank (max Rank) in the high-level parameter PUSCH configuration (PUSCH-Config), and the number of SRS resources indicated by SRI is not greater than max Rank.

[0218] The network device can configure one associated channel state information-reference symbol (CSI-RS) resource for channel measurement for the SRS resource set for non-codebook-based uplink transmission. The terminal obtains the precoding of the SRS transmission of the SRS resource set for non-codebook-based uplink transmission according to the associated CSI-RS resource.

[0219] For non-codebook-based uplink transmission, the CSI-RS configured by the network device needs to be measured in the actual system, and the terminal obtains the uplink channel information by measuring the downlink signal through uplink-downlink reciprocity. The main processes include:

[0220] (1) The network device configures an associated downlink CSI-RS for terminal downlink channel sounding for non-codebook-based transmission.

[0221] (2) The terminal selects a precoding matrix through downlink channel calculation, and sends SRS on each precoded beam direction on the configured SRS resource set.

[0222] (3) The network device performs uplink channel detection on the SRS, schedules resources for the UE, and notifies the terminal through downlink signaling, and selects the beam in the precoding matrix through SRI indication.

[0223] (4) The terminal determines the actual precoding and the allowed number of layers using the modified precoding matrix, and sends PUSCH; the terminal determines the limitation of precoding indication according to the high-layer parameter maxRank, and the number of SRS resources indicated by SRI is not greater than maxRank. In order to realize the modification of the precoding matrix actually used by the terminal by the network device, the network device needs to configure an SRS resource set for the terminal for non-codebook-based transmission.

[0224] For the non-codebook transmission scheme, the network device can configure one SRS resource set for the terminal, containing 1 to 4 SRS resources, and each SRS resource contains 1 SRS port. When the network device configures multiple SRS resources for the terminal for non-codebook-based uplink transmission, the multiple SRS resources have the same time domain type, i.e. all SRS resources are periodic SRS or semi-persistent SRS or aperiodic SRS. The network device can indicate one or more SRS resources to the terminal through SRI for the determination of PUSCH precoding, and the number of SRS resources corresponding to SRI is the number of PUSCH transmission streams. When the network device configures only one SRS resource for the terminal for non-codebook-based uplink transmission, the SRI indication field is not included in the DCI for uplink authorization.

[0225] Figure 1dA schematic diagram of the non-codebook-based uplink transmission procedure provided by an example embodiment of the present disclosure is shown, which is performed by the terminal device 10 and the network device 20 described above.

[0226] In the non-codebook-based uplink transmission procedure, the precoding matrix is no longer limited in a fixed candidate set. The network device 20 first sends the CSI-RS and SRS resource configuration information to the terminal device 10, the SRS resource configuration including at least one SRS resource and the time-frequency resource location of each SRS resource, and then the terminal device 10 calculates at least one precoding matrix that can be used based on the measurement result of the CSI-RS through singular value decomposition and other algorithms. Then the terminal device 10 sends at least one SRS to the network device 20 based on the SRS resource configuration, the network device 20 obtains the channel conditions of each uplink channel based on the received at least one SRS, and then provides DCI to the terminal device 10, the DCI including at least SRI. Finally, the terminal device 10 determines the precoding matrix used this time among the precoding matrices that can be used based on the SRI, and sends the PUSCH to the network device 20 based on the SRI and the precoding matrix used this time.

[0227] The terminal device 10 determines the precoding matrix used this time among the precoding matrices that can be used based on the SRI, and sends the PUSCH to the network device 20 based on the SRI and the precoding matrix used this time.

[0228] The specific method of SRI indication field indication for non-codebook transmission in some embodiments of the present disclosure is shown in the following table, L max That is, the number of transmission layers configured by the network device is limited, and the terminal device determines the corresponding table of SRI and the number of bits of the SRI indication field according to this parameter configuration. The L max is 1, the L max of table 5 is 2, the L max of table 6 is 3, the L max of table 7 is 4.

[0238] The embodiment of the present disclosure provides a configuration method of enhanced SRS resources, which can configure SRS resources supporting two or more SRS ports at a time, so that even if the terminal device supports different antenna panels, when the dynamic change of the antenna panel is needed, the SRS resource corresponding to the current antenna panel can be flexibly used to send SRS, and the SRS resource does not need to be reconfigured by using the RRC message before and after the dynamic change of the antenna panel.

[0239] Figure 2a FIG. 1 is an interaction schematic diagram of the configuration method of SRS resources according to an embodiment of the present disclosure. As shown in FIG. 1, the embodiment of the present disclosure relates to a configuration method of SRS resources, which is used for a communication system 100, and the above method comprises the following steps. Figure 2a

[0240] Step 101: The terminal device 10 sends first information to the network device 20.

[0241] In some embodiments, the terminal device supports sending / receiving data using one or more antenna panels. The first information is used to indicate a maximum SRS port number set supported by different antenna panels of the terminal device. The maximum SRS port number set includes at least two maximum SRS port numbers, any two maximum SRS port numbers in the at least two maximum SRS port numbers are different, and each maximum SRS port number is a maximum SRS port number supported by one or more antenna panels in the terminal device.

[0242] In some embodiments, the maximum SRS port numbers supported by different antenna panels in the terminal device can be the same or different.

[0243] In some embodiments, the first information includes at least two maximum SRS port numbers, and the at least two maximum SRS port numbers correspond to different antenna panels of the terminal device.

[0244] In some embodiments, the first information carries a terminal capability value set, which is used to indicate a maximum SRS port number set supported by the antenna panel of the terminal device; or, the terminal capability value set is used to indicate a maximum SRS port number set supported by each antenna panel of the terminal device; or, the terminal capability value set is used to indicate a maximum SRS port number set supported by at least two antenna panels of the terminal device; or, the terminal capability value set is used to indicate a maximum SRS port number set supported by different antenna panels of the terminal device; or, the terminal capability value set is used to indicate a maximum SRS port number set supported by a heterogeneous panel of the terminal device, and the heterogeneous panel refers to an antenna panel with different capabilities.

[0245] ​In some embodiments, the terminal capability value set is carried in a terminal capability report. In some embodiments, the terminal capability report can also be understood as: terminal capability information, beam report, uplink beam report, downlink beam report, packet-based downlink beam report, packet-based uplink beam report, etc. names or signaling.

[0246] In some embodiments, the antenna panel refers to an antenna panel used for uplink transmission, and the terminal capability refers to the maximum number of SRS ports supported when uplink transmission is used. Alternatively, the antenna panel refers to an antenna panel used for uplink simultaneous transmission, and the capability refers to the maximum number of SRS ports supported when uplink simultaneous transmission is used.

[0247] In some embodiments, the terminal device has 2, or 4, or 8 antenna panels. This embodiment does not limit the number of antenna panels of the terminal device, and is exemplified by taking the number of antenna panels as 4. The antenna panel can also be referred to as a panel.

[0248] In some embodiments, the terminal capability value set includes one maximum SRS port number. That is, the maximum SRS port numbers supported by different antenna panels are the same.

[0249] In some embodiments, the terminal capability value set includes at least two maximum SRS port numbers, which correspond to different antenna panels of the terminal device. Alternatively, the at least two maximum SRS port numbers correspond to different capability antenna panels of the terminal device. Alternatively, the at least two maximum SRS port numbers correspond to different capability antenna panels of the terminal device when supporting uplink transmission or uplink simultaneous transmission. That is, the maximum SRS port numbers supported by different antenna panels are different.

[0250] For example, assume that the terminal device has 4 different antenna panels, panel#0, panel#1, panel#2, and panel#3. Among them, panel#0 supports a maximum of 1 SRS port, panel#1 supports a maximum of 2 SRS ports, panel#2 supports a maximum of 2 SRS ports, and panel#3 supports a maximum of 4 SRS ports. Then, the terminal capability value set in the terminal capability report sent by the terminal device to the network device is {1, 2, 4}.

[0251] Step 102: The network device 20 receives the first information sent by the terminal device 10;

[0252] The network device receives and checks the first information from the terminal device. For example, the first information includes a terminal capability value set. The maximum SRS port number set supported by the multiple antenna panels used by the terminal device is determined.

[0253] Step 103: The network device 20 sends the second information to the terminal device 10;

[0254] The network device sends the second information to the terminal device. In some embodiments, the second information includes SRS resource configuration sent by the network device to the terminal device, and the SRS resource configuration includes SRS resources, which are related to the first information. In some embodiments, the terminal capability value set carried in the first information includes at least two terminal capability values, or a terminal capability value index, or a maximum SRS port number, which should be understood as the same meaning.

[0255] In some embodiments, the SRS resource configuration has SRS resources or SRS resource sets supporting different SRS port numbers. The different SRS port numbers are indicated by the terminal capability value set or determined based on the terminal capability value set.

[0256] For example, the terminal capability value set is {1, 2, 4}, and the SRS resource configuration includes SRS resources with 1 SRS port number, SRS resources with 2 SRS port numbers, and SRS resources with 4 SRS port numbers.

[0257] In some embodiments, the SRS resources with the same SRS port number in the SRS resource configuration are configured with one or more.

[0258] In some embodiments, the above-mentioned SRS resource configuration method is used at least for the following two cases:

[0259] The first case is CB-based multi-panel uplink simultaneous transmission.

[0260] In some embodiments, the SRS resource configuration in the CB-based multi-panel uplink simultaneous transmission includes the following cases (each case can be implemented as an embodiment independently):

[0261] The first case is at least two SRS resources.

[0262] In some embodiments, the SRS resource configuration includes at least two SRS resources, and the number of SRS ports of the at least two SRS resources corresponds to the maximum SRS port number in the maximum SRS port number set one by one. In some embodiments, the number of resources of the at least two SRS resources is the same as the number of elements in the maximum SRS port number set, and the number of SRS ports corresponding to the at least two SRS resources respectively has a one-to-one correspondence with each element in the maximum SRS port number set. In some embodiments, the number of SRS ports of the i-th SRS resource is the same as the i-th maximum SRS port number, and the i-th SRS resource is the SRS resource arranged in the i-th position in the first order among the at least two SRS resources; the i-th maximum SRS port number is the set element arranged in the i-th position in the second order in the maximum SRS port number set. The first order and the second order can be in the order of small to large SRS port number, or in the order of large to small SRS port number.

[0263] For example, the terminal capability value set in the terminal capability report sent by the terminal device to the network device is {1, 2, 4}, and the at least two SRS resources include an SRS resource with 1 SRS port number, an SRS resource with 2 SRS port numbers, and an SRS resource with 4 SRS port numbers.

[0264] The second type is at least one SRS resource.

[0265] In some embodiments, the SRS resource configuration includes at least one SRS resource, and the number of SRS ports of each SRS resource in the at least one SRS resource is a first number, and the first number is the maximum value of at least two maximum SRS port numbers in the terminal capability value set.

[0266] For example, the terminal capability value set in the terminal capability report sent by the terminal device to the network device is {1, 2, 4}, and the first number is 4, that is, the SRS resource in the SRS resource configuration is an SRS resource with 4 SRS port numbers.

[0267] The third type is at least two SRS resource sets.

[0268] In some embodiments, the SRS resource configuration includes at least two SRS resource sets, each SRS resource set includes at least one SRS resource. The number of SRS ports of the at least two SRS resource sets corresponds to the maximum SRS port number in the maximum SRS port number set. In some embodiments, the number of resources in the at least two SRS resource sets is the same as the number of elements in the maximum SRS port number set, and the number of SRS ports corresponding to the at least two SRS resource sets respectively corresponds to each element in the maximum SRS port number set; in some embodiments, the number of SRS ports of the ith SRS resource set corresponds to the maximum SRS port number in the maximum SRS port number set.

[0269] For example, assuming that the terminal capability value set in the terminal capability report sent by the terminal device to the network device is {1, 2, 4}, the SRS resource configuration includes a first SRS resource set and a second SRS resource set. The first SRS resource set includes an SRS resource with 1 SRS port, an SRS resource with 2 SRS ports, and an SRS resource with 4 SRS ports, and the second SRS resource set includes an SRS resource with 1 SRS port, an SRS resource with 2 SRS ports, and an SRS resource with 4 SRS ports.

[0270] The second case is NCB-based multi-panel uplink simultaneous transmission.

[0271] In some embodiments, the SRS resource configuration in the NCB-based multi-panel uplink simultaneous transmission includes the following cases (each case can be implemented as an embodiment independently):

[0272] The first case is a first number of single-port SRS resources.

[0273] In some embodiments, the first number is the maximum value of at least two maximum SRS port numbers in the terminal capability value set. For example, assuming that the terminal capability value set in the terminal capability report sent by the terminal device to the network device is {1, 2, 4}, the first number is 4, that is, the SRS resource configuration includes 4 single-port SRS resources.

[0274] For example, the SRS port of each SRS resource is the same, and the SRS port of different SRS resources is different, such as the SRS port of the first SRS resource is 1000, the SRS port of the second SRS resource is 1001, the SRS port of the third SRS resource is 1002, and the SRS port of the fourth SRS resource is 1003.

[0275] The second case is a first number of single-port SRS resource sets.

[0276] In some embodiments, the first number is a maximum value of at least two maximum SRS port numbers in the set of terminal capability values. For example, the set of terminal capability values in the terminal capability report sent by the terminal device to the network device is {1, 2, 4}, and the first number is 4, i.e., the SRS resource configuration includes four single-port SRS resource sets. The SRS ports of the SRS resources in each SRS resource set are the same, and the SRS ports of the SRS resources in different SRS resource sets are different, such as the SRS ports in the first SRS resource set are 1000, the SRS ports in the second SRS resource set are 1001, the SRS ports in the third SRS resource set are 1002, and the SRS ports in the fourth SRS resource set are 1003.

[0277] Step 104: The terminal device 10 receives the second information sent by the network device 20.

[0278] The terminal device receives the SRS resource configuration sent by the network device based on the set of terminal capability values, and the SRS resource configuration includes SRS resources corresponding to the set of terminal capability values.

[0279] Step 105: The network device 20 sends third information to the terminal device 10.

[0280] In some embodiments, the network device sends the third information to the terminal device. For example, the third information is a reference signal (RS) for beam measurement, and the RS is used for measuring at least two beams. In some embodiments, the RS includes a CSI-RS and / or a synchronization signal block (SSB). In some embodiments, the RS corresponds to the beam one by one, or it is understood that the number of RSs is consistent with the number of beams. The number of beams does not exceed the maximum number of beams. The maximum number of beams can be the maximum number of beams for uplink multi-panel transmission, or the maximum number of beams for uplink simultaneous transmission, or the maximum number of beams for uplink non-simultaneous transmission. The maximum number of beams is predefined by the communication protocol, or configured by the network device.

[0281] In some embodiments, the at least two beams are beams that support uplink transmission; or the at least two beams are beams that support uplink multi-panel transmission; or the at least two beams are beams that support uplink simultaneous transmission; or the at least two beams are beams that support uplink non-simultaneous transmission.

[0282] In some embodiments, the at least two beams correspond to at least two antenna panels one-to-one. In some embodiments, the at least two beams correspond to at least two antenna panels which are homogeneous panels. In some embodiments, the at least two antenna panels are panels with the same capability. In some embodiments, the at least two antenna panels are panels with the same maximum number of supported SRS ports. In some embodiments, the at least two antenna panels are panels with the same maximum number of supported layers.

[0283] In some embodiments, the number of beams in the at least two beams is the same as the number of panels in the at least two antenna panels. In other words, the at least two beams correspond to the at least two antenna panels one-to-one.

[0284] Step 106: The terminal device 10 measures the third information sent by the network device 20;

[0285] In some embodiments, the terminal device measures the third information sent by the network device. Optionally, the terminal device performs beam management on the beams based on the RS sent by the network device, and the beam management includes performing beam measurement on the beams corresponding to the received RS. For example, the beam measurement can include: the terminal device receives a plurality of CSI-RS resources or a plurality of SSB resources indicated by the network device through TCI or the like, measures all the CSI-RS resources or SSB resources, and determines a CSI-RS resource indicator (CRI) or a synchronization signal block resource indicator (SSB RI) suitable for uplink simultaneous transmission.

[0286] Step 107: The terminal device 10 reports the fourth information to the network device 20;

[0287] In some embodiments, the fourth information includes the measurement result of the terminal device on the third information and the terminal capability value index. For example, the fourth information is a beam report, and the terminal device reports the beam report to the network device after performing beam measurement. The beam report is a specific beam report format or signaling, which carries the measurement result and the terminal capability value index of the at least two beams. In other words, the beam report carries the beam information of the at least two beams corresponding to the RS and the terminal capability value index of the at least two beams.

[0288] The beam information includes at least one of an identifier for identifying a beam, an index for identifying a beam, a measurement result of a beam, and a transmission type supported by a beam.

[0289] In some embodiments, the identification or index for identifying the beam can be indicated by at least one of a beam identification, a beam pair identification, spatial relation information, a spatial setting, a spatial Rx parameter, a transmit filter (Tx spatial filter), a spatial domain receive filter, a spatial domain transmit filter, a TCI state, a Quasi CoLocation Type D (QCL Type D), and the like.

[0290] In some embodiments, the measurement result of the beam includes at least one of a CRI, an SSB RI, a Layer 1-Reference Signal Receiving Power (L1-RSRP), a Layer 1-Signal to Interference plus Noise Ratio (L1-SINR).

[0291] In some embodiments, the transmission type refers to at least one of an uplink transmission, an uplink multi-panel transmission, an uplink simultaneous transmission, an uplink non-simultaneous transmission, a downlink transmission, a downlink multi-panel transmission, a downlink simultaneous transmission, and a downlink non-simultaneous transmission.

[0292] In some embodiments, the terminal capability value index is used to indicate a maximum number of SRS ports supported by at least two antenna panels. Alternatively, the terminal capability value index is used to indicate a maximum number of SRS ports supported by at least two antenna panels corresponding to at least two beams. Alternatively, the terminal capability value index is used to indicate a maximum number of SRS ports supported by at least two homogeneous panels corresponding to at least two beams. In the case that the at least two antenna panels corresponding to the at least two beams are homogeneous panels, the maximum number of SRS ports supported by the at least two antenna panels is the same.

[0293] In some embodiments, the terminal capability value index occupies 1 bit or 2 bits.

[0294] In an embodiment, the terminal capability value index (or terminal capability value set index) is used to indicate the capability type of at least two antenna panels corresponding to at least two beams through the index value, and different index values can correspond to different capability types. For example, a terminal device has four antenna panels panel#0, panel#1, panel#2, and panel#3, and the maximum number of SRS ports supported by the four antenna panels is 4, 4, 2, and 2 respectively, and the terminal capability value set UE capability value set sent by the terminal device to the network device in advance can be defined as {4, 2}. Assuming that the antenna panels corresponding to the at least two beams to be reported currently are panel#0 and panel#1, the terminal capability value set index UE capability value set index#0 indicates that the maximum number of SRS ports supported by the at least two antenna panels is 4; assuming that the antenna panels corresponding to the at least two beams to be reported currently are panel#2 and panel#3, the terminal capability value set index UE capability value set index#01 indicates that the maximum number of SRS ports supported by the at least two antenna panels is 2. Wherein, the terminal capability value index UE capability value set index#0 can also be simplified as cap_index0, the terminal capability value index UE capability value set index#1 can also be simplified as cap_index1, and other representation forms are not limited in the present application.

[0295] In an example, the beam information of two beams, and the terminal capability value index of the two beams are reported as follows: {CRI0+L1-RSRP0, cap_index0; CRI1+L1-RSRP1, cap_index1}. Wherein, “CRI0+L1-RSRP0” represents the measurement result of the first beam of the two beams, corresponding to panel#0; “CRI1+L1-RSRP1” represents the measurement result of the second beam of the two beams, corresponding to panel#1; “cap_index0” represents that the maximum number of SRS ports supported by panel#0 is 4; “cap_index1” represents that the maximum number of SRS ports supported by panel#1 is 4.

[0296] In some embodiments, the above beam report carries the beam information of at least two beams, and the terminal capability value index corresponding to (or corresponding one by one) each beam. For example,

[0297] {beam information of beam 1, first terminal capability value index;

[0298] Beam information of beam 2, second terminal capability value index;

[0299] Beam information of beam 3, third terminal capability value index.

[0300] In some embodiments, the terminal capability value index corresponding to different beams can be the same or different.

[0301] In some embodiments, the terminal capability value index corresponding to different beams can be the same or different.

[0302] {Beam information of beam 1, beam information of beam 2, beam information of beam 3, fourth terminal capability value index}.

[0303] In this reporting manner, the terminal capability value indexes of different beams are the same.

[0304] Step 108: The network device 20 receives the fourth information reported by the terminal device 10.

[0305] The network device receives the fourth information reported by the terminal device. For example, the measurement result based on the RS for beam measurement and the terminal capability value index corresponding to the beam.

[0306] Step 109: The network device 20 sends the fifth information to the terminal device 10.

[0307] The network device sends the fifth information to the terminal device based on the received measurement result and terminal capability value index. For example, the fifth information includes UL TCI state. The UL TCI state contains a QCL Type D source RS, which is used to indicate an uplink beam. In the beam report reported by the terminal device to the network device in advance, the measurement result of the uplink beam and the corresponding relationship of the terminal capability value index are reported. Based on the corresponding relationship between the uplink beam and the terminal capability value index, the first terminal capability value index corresponding to the QCL Type D source RS can be determined. The first terminal capability value index is one or more of the terminal capability value indexes reported by the terminal device to the network device.

[0308] Step 110: The terminal device 10 receives the fifth information sent by the network device 20.

[0309] The terminal device receives the fifth information sent by the network device. Illustratively, the fifth information includes UL TCI state. Specifically, the terminal device receives QCL Type D source RS. Specifically, the terminal device receives the first terminal capability value index corresponding to the QCL Type D source RS.

[0310] Step 111: The terminal device 10 sends the sixth information to the network device 20.

[0311] The terminal device sends the sixth information to the network device based on the first terminal capability value index corresponding to the QCL Type D source RS included in the UL TCI state sent by the network device. In some embodiments, the sixth information is, for example, a beam grouping configuration, or a grouping-based beam configuration, or beam grouping division information, or beam pair division information. Illustratively, the sixth information includes SRS.

[0312] In some embodiments, in the CB-based multi-panel uplink simultaneous transmission, according to different SRS resource configurations sent by the network device, the above step 111 can be implemented as the following sub-steps:

[0313] In some embodiments, the SRS resource configuration includes at least two SRS resources. Illustratively, as shown in Figure 2b The above step 111 can be implemented as:

[0314] Step 1111: Send SRS using the first SRS resource.

[0315] In some embodiments, the terminal device sends SRS using the first SRS resource in the received SRS resource configuration. The first SRS resource belongs to the at least two SRS resources received by the terminal device. The number of SRS ports of the first SRS resource is equal to the maximum number of SRS ports corresponding to the first antenna panel.

[0316] The first antenna panel is determined based on the UL TCI state. Optionally, the first antenna panel is determined based on the QCL Type D source RS in the UL TCI state. The UL TCI state contains the QCL Type D source RS, which is used to indicate the uplink beam. In the beam report pre-reported by the terminal device to the network device, the measurement result of the uplink beam and the corresponding relationship of the terminal capability value index are reported. Based on the corresponding relationship of the uplink beam and the terminal capability value index, the first terminal capability value index corresponding to the QCL source RS can be determined. The first antenna panel is the antenna panel corresponding to the first terminal capability value index.

[0317] For example, assuming that the terminal device has four antenna panels panel#0, panel#1, panel#2, panel#3, and the maximum number of SRS ports supported by the four antenna panels are 4, 4, 2, 2 respectively, the terminal capability value set sent by the terminal device to the network device in advance can be defined as {4, 2}. Assuming that the first antenna panel determined based on the UL TCI state is panel#0, the terminal capability value set index indicates that the maximum number of SRS ports supported by the first antenna panel is 4, that is, the SRS is sent using the SRS resource with 4 SRS ports.

[0318] In some embodiments, the SRS resource configuration includes at least one SRS resource. For example, as shown in FIG. 11, the SRS resource configuration includes at least one SRS resource. Figure 2c The step 111 can be implemented as follows.

[0319] Step 1112: Send SRS through the second number of SRS ports of the at least one SRS resource.

[0320] In some embodiments, the number of SRS ports of each SRS resource in the at least one SRS resource is a first number. The first number is the maximum value of at least two maximum SRS port numbers in the terminal capability value set. For example, the terminal device has four antenna panels panel#0, panel#1, panel#2, panel#3, and the maximum number of SRS ports supported by the four antenna panels are 4, 4, 2, 2 respectively, the terminal capability value set sent by the terminal device to the network device in advance can be defined as {4, 2}. The maximum value of the corresponding maximum SRS port numbers in the terminal capability value set is 4, that is, the first number is 4, and the SRS resource configuration sent by the network device to the terminal device includes the SRS resource with 4 SRS ports.

[0321] The terminal device sends SRS through the second number of SRS ports of at least one SRS resource, that is, the terminal device sends SRS using at least one SRS resource as the SRS resource of the second number of SRS ports. The second number is equal to the maximum number of SRS ports corresponding to the first antenna panel. The first antenna panel is determined based on the UL TCI state. Optionally, the first antenna panel is determined based on the QCL Type D source RS in the UL TCI state. The UL TCI state includes a QCLType D source RS, which is used to indicate an uplink beam. The measurement results of the uplink beam and the correspondence between the terminal capability value index are reported in the beam report pre-reported by the terminal device to the network device. Based on the correspondence between the uplink beam and the terminal capability value index, the first terminal capability value index corresponding to the QCL source RS can be determined. The first antenna panel is the antenna panel corresponding to the first terminal capability value index.

[0322] Assuming that the first antenna panel determined based on the UL TCI state is panel #2, the terminal capability value set index indicates that the maximum number of SRS ports supported by the first antenna panel is 2, that is, the second number is 2, then the terminal device sends SRS as SRS resources of 4 SRS ports as SRS resources of 2 ports.

[0323] In some embodiments, the second number of SRS ports is a subset of the first number of SRS ports. The second number is less than or equal to the first number, that is, the number of ports of the SRS resource for the terminal device to send SRS is less than or equal to the number of ports of the SRS resource in the SRS resource configuration received by the terminal device.

[0324] Exemplarily, the first number of SRS ports includes SRS port 1000, SRS port 1001, SRS port 1002 and SRS port 1003, then the second number of SRS ports includes SRS port 1000 and SRS port 1001, or the second number of SRS ports includes SRS port 1000 and SRS port 1002, or the second number of SRS ports includes SRS port 1000 and SRS port 1003, or the second number of SRS ports includes SRS port 1001 and SRS port 1002, or the second number of SRS ports includes SRS port 1001 and SRS port 1003, or the second number of SRS ports includes SRS port 1002 and SRS port 1003.

[0325] In some embodiments, the second number of SRS ports are selected from the first number of SRS ports based on a predefined rule. For example, SRS ports 1001 and 1002 are selected from the first number of SRS ports as the second number of SRS ports based on a predefined rule.

[0326] In some embodiments, the second number of SRS ports are selected from the first number of SRS ports based on a terminal device implementation.

[0327] In some embodiments, the SRS resource configuration includes at least two SRS resource sets. For example, as shown in FIG. 11B, the SRS resource configuration includes SRS resource set 1101 and SRS resource set 1102. Figure 2d The step 111 can be implemented as follows:

[0328] Step 1113: transmitting SRS using the first SRS resource set.

[0329] In some embodiments, the terminal device transmits SRS using the first SRS resource set in the received SRS resource configuration. The first SRS resource set belongs to the at least two SRS sets received by the terminal device, and the number of SRS ports of each SRS resource in the first SRS resource set is equal to the maximum number of SRS ports corresponding to the first antenna panel.

[0330] The first antenna panel is determined based on the UL TCI state. Optionally, the first antenna panel is determined based on a QCL Type D source RS in the UL TCI state. The UL TCI state contains the QCL Type D source RS, which is used to indicate the uplink beam. In the beam report pre-reported by the terminal device to the network device, the measurement result of the uplink beam and the corresponding relationship of the terminal capability value index are reported. Based on the corresponding relationship of the uplink beam and the terminal capability value index, the first terminal capability value index corresponding to the QCL source RS can be determined. The first antenna panel is the antenna panel corresponding to the first terminal capability value index.

[0331] Exemplarily, assuming that the terminal device has 4 antenna panels panel#0, panel#1, panel#2, panel#3 respectively, and the maximum SRS port numbers supported by the four antenna panels are 4, 4, 2, 2 respectively, the terminal capability value set pre-transmitted by the terminal device to the network device can be defined as {4, 2}. The terminal device receives the SRS resource configuration from the network device, and the SRS resource configuration includes at least two SRS resource sets, and the at least two SRS resource sets include a first SRS resource set and a second SRS resource set. The first SRS resource set includes 2 SRS port number SRS resources, and the second SRS resource set includes 4 SRS port number SRS resources.

[0332] Based on the determination of the first antenna panel being panel#2 according to the UL TCI state, the terminal capability value set index indicates that the maximum SRS port number supported by the first antenna panel is 2, and the terminal device transmits SRS using the 2 SRS port number SRS resources in the first SRS resource set.

[0333] In some embodiments, in the NCB-based multi-panel uplink simultaneous transmission, according to different SRS resource configurations transmitted by the network device, the above step 111 can be implemented as the following sub-steps:

[0334] In some embodiments, the SRS resource configuration includes a first number of single-port SRS resources. Exemplarily, as shown in Figure 2e The above step 111 can be implemented as:

[0335] The first number is the maximum value of the at least two maximum SRS port numbers in the terminal capability value set. Exemplarily, the terminal device has 4 antenna panels panel#0, panel#1, panel#2, panel#3 respectively, and the maximum SRS port numbers supported by the four antenna panels are 4, 4, 2, 2 respectively, the terminal capability value set pre-transmitted by the terminal device to the network device can be defined as {4, 2}. The maximum value of the corresponding maximum SRS port numbers in the terminal capability value set is 4, i.e. the first number is 4, and the SRS resource configuration transmitted by the network device to the terminal device includes 4 single-port SRS resources.

[0336] Step 1114: transmitting SRS using the second number of SRS resources.

[0337] The terminal device transmits SRS using the second number of single-port SRS resources in the first number of single-port SRS resources, and the second number of SRS resources is a subset of the first number of single-port SRS resources. The second number of SRS resources in the first number of single-port SRS resources is equal to the maximum SRS port number corresponding to the first antenna panel.

[0338] The first antenna panel is determined based on the UL TCI state. Optionally, the first antenna panel is determined based on a QCL Type D source RS in the UL TCI state. The UL TCI state contains the QCL Type D source RS, which is used to indicate an uplink beam. In a beam report previously reported by the terminal device to the network device, there is a measurement result of the uplink beam, and a correspondence relationship of a terminal capability value index. Based on the correspondence relationship of the uplink beam and the terminal capability value index, a first terminal capability value index corresponding to the QCL source RS can be determined. The first antenna panel is an antenna panel corresponding to the first terminal capability value index.

[0339] For example, assuming that the first antenna panel determined based on the UL TCI state is panel#2, the terminal capability value set index indicates that the maximum number of SRS ports supported by the first antenna panel is 2, i.e., the second number is 2, and the terminal device will use 2 single-port SRS resources from 4 single-port SRS resources to send SRS.

[0340] In some embodiments, the second number is less than or equal to the first number, i.e., the number of single-port SRS resources used by the terminal device to send SRS is less than or equal to the number of single-port SRS resources in the SRS resource configuration received by the terminal device.

[0341] In some embodiments, the second number of SRS resources is selected from the first number of single-port SRS resources based on a predefined rule.

[0342] In some embodiments, the second number of SRS resources is selected from the first number of single-port SRS resources based on terminal implementation.

[0343] For example, the terminal device receives an SRS resource configuration from the network device, which includes 4 single-port SRS resources, including single-port SRS resource 1, single-port SRS resource 2, single-port SRS resource 3, and single-port SRS resource 4. The maximum number of SRS ports corresponding to the first antenna panel is 2. Then, based on a predefined rule or based on terminal implementation, 2 single-port SRS resources are selected from single-port SRS resource 1, single-port SRS resource 2, single-port SRS resource 3, and single-port SRS resource 4 to send SRS.

[0344] In some embodiments, the SRS resource configuration includes a first number of single-port SRS resource sets. For example, as shown in Figure 2f The above step 111 can be implemented as:

[0345] The first quantity is a maximum value of at least two maximum SRS port numbers in the terminal capability value set. For example, the terminal device has four antenna panels panel#0, panel#1, panel#2, panel#3, and the maximum SRS port numbers supported by the four antenna panels are 4, 4, 2, and 2 respectively. The terminal capability value set pre-reported by the terminal device to the network device can be defined as {4, 2}. The maximum value of the corresponding maximum SRS port numbers in the terminal capability value set is 4, that is, the first quantity is 4. Therefore, the network device sends four single-port SRS resource sets to the terminal device in the SRS resource configuration.

[0346] Step 1115: sending SRS using the second quantity of SRS resource sets.

[0347] In some embodiments, the terminal device sends SRS using the second quantity of the first quantity of single-port SRS resource sets. The second quantity of SRS resource sets is a subset of the first quantity of single-port SRS resource sets, and the second quantity is equal to the maximum SRS port number corresponding to the first antenna panel. The first antenna panel is determined based on the UL TCI state. Optionally, the first antenna panel is determined based on the QCL Type D source RS in the UL TCI state. The UL TCI state contains the QCL Type D source RS, which is used to indicate the uplink beam. In the beam report pre-reported by the terminal device to the network device, the measurement result of the uplink beam and the corresponding relationship between the terminal capability value index are reported. Based on the corresponding relationship between the uplink beam and the terminal capability value index, the first terminal capability value index corresponding to the QCL source RS can be determined. The first antenna panel is the antenna panel corresponding to the first terminal capability value index.

[0348] For example, assuming that the first antenna panel determined based on the UL TCI state is panel#2, the terminal capability value set index indicates that the maximum SRS port number supported by the first antenna panel is 2, that is, the second quantity is 2, and the terminal device will send SRS using two single-port SRS resource sets in the four single-port SRS resource sets.

[0349] In some embodiments, the second quantity is less than or equal to the first quantity, that is, the number of single-port SRS resource sets used by the terminal device to send SRS is less than or equal to the number of single-port SRS resource sets in the SRS resource configuration received by the terminal device.

[0350] In some embodiments, the second number of SRS resource sets are selected from the first number of single-port SRS resource sets based on a predefined rule.

[0351] In some embodiments, the second number of SRS resource sets are selected from the first number of single-port SRS resource sets based on terminal implementation.

[0352] Exemplarily, the SRS resource configuration received by the terminal device from the network device includes four single-port SRS resource sets, including single-port SRS resource set 1, single-port SRS resource set 2, single-port SRS resource set 3, and single-port SRS resource set 4. The maximum number of SRS ports corresponding to the first antenna panel is 2. Based on predefined rules or based on terminal implementation, two single-port SRS resource sets are selected from single-port SRS resource set 1, single-port SRS resource set 2, single-port SRS resource set 3, and single-port SRS resource set 4 to transmit the SRS.

[0353] Step 112 : The network device 20 receives the sixth information sent by the terminal device 10 .

[0354] The network device receives the SRS sent by the terminal device based on different SRS configurations.

[0355] In the embodiment of the present disclosure, steps 105, 106, 107, 108, 109, 110, 111, 112, 1111, 1112, 1113, 1114, and 1115 are all optional steps. In different embodiments, one or more of these steps may be omitted or replaced.

[0447] Embodiments of the present disclosure relate to a method for configuring SRS resources, and the method comprises the following steps:

[0448] Example Embodiment I:

[0449] In some embodiments, for CB-based multi-panel uplink simultaneous transmission, the network device configures SRS resources with different port numbers in the same SRS resource set according to a set of terminal capability values in the terminal capability report, and the terminal device selects SRS resources corresponding to the antenna panel capability value according to the beam information indicated by the TCI. For example, if the set of terminal capability values reported by the terminal device is {1, 2, 4}, three SRS resources are configured in an SRS resource set for codebook transmission, including one SRS resource with one SRS port, one SRS resource with two SRS ports, and one SRS resource with four SRS ports. If the capability value of the antenna panel corresponding to the QCL source RS in the UL TCI is reported as 2, the terminal device uses the SRS resource with two SRS ports for transmission.

[0450] In some embodiments, one or more SRS resources with the same port number are allowed to be configured.

[0451] In some embodiments, SRS resources with different port numbers are allowed to be configured; however, only all SRS resources corresponding to one port number can be transmitted.

[0452] In some embodiments, more than two SRS resources are allowed to be configured in one SRS resource set.

[0453] In some embodiments, for NCB-based multi-panel uplink simultaneous transmission, the network device configures SRS resources in one SRS resource set according to the maximum SRS port number in the terminal capability report, and the terminal device selects SRS resources corresponding to the antenna panel capability value according to the beam information indicated by the TCI. For example, if the set of terminal capability values reported by the terminal device is {1, 2, 4}, four single-port SRS resources are configured in an SRS resource set for codebook transmission, and if the capability value of the antenna panel corresponding to the QCL source RS in the UL TCI is reported as 2, the terminal device uses two single-port SRS resources for transmission.

[0454] In some embodiments, which two SRS resources are used can be determined according to a predefined rule, such as selecting P ports starting from port 0.

[0455] Example Embodiment II:

[0456] In some embodiments, for CB-based multi-panel uplink simultaneous transmission, the network device configures SRS resources in an SRS resource set according to the maximum SRS port number in the terminal capability report, one or more SRS resources can be configured in one SRS resource set, and the terminal device selects SRS resources corresponding to the antenna panel capability value to transmit according to the beam information indicated by the TCI. For example, the terminal device reports a terminal capability value set {1, 2, 4}, and one or more SRS resources with 4 ports are configured in an SRS resource set for codebook transmission. If the corresponding antenna panel capability value of the QCL source RS in the UL TCI is reported as 2, the terminal device uses 2 ports of the SRS resource with 4 ports as SRS resources with 2 ports for transmission.

[0457] In some embodiments, the rule for selecting ports needs to be determined. For example, P ports are selected from port 0.

[0458] In some embodiments, there is no need for rules, and the terminal device determines how to transmit P ports.

[0459] In some embodiments, for NCB-based multi-panel uplink simultaneous transmission, the network device configures SRS resources in an SRS resource set according to the maximum SRS port number in the terminal capability report, and the terminal device selects SRS resources corresponding to the antenna panel capability value to transmit according to the beam information indicated by the TCI. For example, the reported terminal capability value set is {1, 2, 4}, and four single-port SRS resources are configured in an SRS resource set for codebook transmission. If the corresponding antenna panel capability value of the QCL source RS in the UL TCI is reported as 2, the terminal uses 2 single-port SRS resources of the 4 single-port SRS resources for transmission.

[0460] In some embodiments, which two SRS resources are used can be determined according to a predefined rule, such as selecting P ports from port 0.

[0461] Example three:

[0462] In some embodiments, for CB-based multi-panel uplink simultaneous transmission, the network device configures different SRS resource sets for different port numbers in the terminal capability report, for the terminal device to select SRS resources corresponding to the antenna panel capability value according to the beam information indicated by the TCI. For example, if the terminal device reports a terminal capability value set {1, 2, 4}, three SRS resource sets are configured in an SRS resource set for codebook transmission, which are SRS resource set with SRS port number 1, SRS resource set with SRS port number 2 and SRS resource set with SRS port number 4. If the corresponding QCL source RS in the UL TCI reports an antenna panel capability value of 2, the terminal device uses the SRS resource set with SRS port number 2 for transmission.

[0463] In some embodiments, for NCB-based multi-panel uplink simultaneous transmission, the network device configures different SRS resource sets for different port numbers in the terminal capability report, for the terminal device to select SRS resources corresponding to the antenna panel capability value according to the beam information indicated by the TCI. For example, if the terminal device reports a terminal capability value set {1, 2, 4}, four single-port SRS resources are configured in an SRS resource set for non-codebook transmission. If the corresponding QCL source RS in the UL TCI reports an antenna panel capability value of 2, the terminal device uses two single-port SRS resource sets corresponding to two single-port SRS resources in the four single-port SRS resources for transmission.

[0464] In the embodiments of the present disclosure, part or all of the steps, and optional implementation manners thereof, can be combined with part or all of the steps in other embodiments, or can be combined with optional implementation manners of other embodiments.

[0465] The embodiments of the present disclosure further provide a device for implementing any of the above methods. For example, a device is provided, which includes units for implementing the steps performed by the terminal device in any of the above methods. For another example, another device is provided, which includes units for implementing the steps performed by the network device (e.g., an access network device, a core network function node, a core network device, etc.) in any of the above methods. It should be understood that the division of units in the above device is only a logical functional division, and all or part of the units can be integrated into one physical entity, or can be physically separated. In addition, the units in the device can be implemented in the form of processor invoking software: for example, the device includes a processor, a memory connected to the processor, and the memory stores computer instructions. The processor invokes the computer instructions stored in the memory to implement any of the above methods or to implement the functions of the units of the device. The processor is, for example, a general-purpose processor, such as a central processing unit (CPU) or a microprocessor, and the memory is a memory within the device or a memory outside the device. Alternatively, the units in the device can be implemented in the form of hardware circuitry, and the functions of part or all of the units can be implemented by the design of the hardware circuitry. The hardware circuitry can be understood as one or more processors. For example, in one implementation, the hardware circuitry is an application-specific integrated circuit (ASIC) in which the logical relationship between elements in the circuit is designed to implement the functions of part or all of the units. For another example, in another implementation, the hardware circuitry is a programmable logic device (PLD) that can be implemented by, for example, a field programmable gate array (FPGA), which can include a large number of logic gate circuits. The connection relationship between the logic gate circuits is configured by a configuration file, so as to implement the functions of part or all of the units. All units of the above device can be implemented in the form of processor invoking software, or all units can be implemented in the form of hardware circuitry, or part of the units are implemented in the form of processor invoking software, and the remaining part is implemented in the form of hardware circuitry.

[0466] In the embodiments of the present disclosure, the processor is a circuit with signal processing capability. In one implementation, the processor can be a circuit with instruction reading and running capability, such as a CPU, a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), a digital signal processor (DSP), and the like. In another implementation, the processor can implement certain functions through a logical relationship of a hardware circuit, and the logical relationship of the hardware circuit is fixed or can be reconfigured. For example, the hardware circuit is implemented by an ASIC or a PLD, such as an FPGA. In the reconfigurable hardware circuit, the processor loads a configuration document to implement the configuration of the hardware circuit. It can be understood that the processor loads an instruction to implement the functions of the above part or all units. In addition, the hardware circuit can also be designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), and the like.
