Description

Technical Field

[0002] Currently, the configuration method for Sounding Reference Signals (SRS) used for uplink beam management involves network devices configuring one or more SRS resource sets for terminals, with each SRS resource set including at least one SRS resource. However, in uplink-only (UL only) Transmission Reception Point (TRP) scenarios, when the terminal begins transmitting SRS, the base station does not know which beam direction is better, and therefore cannot determine which SRS resource can be used to indicate the Transmission Configuration Indication (TCI) status. Therefore, how to instruct the terminal to transmit the SRS beam in this scenario is a problem that urgently needs to be solved. Summary of the Invention

[0125] Before introducing the technical solutions of the embodiments of this application, the relevant technologies will be introduced first.

[0126] In related technologies, the current uplink SRS configuration method for beam management is as follows: configure one or more SRS resource sets, each set including X SRS resources, where X is an integer greater than or equal to 1.

[0127] The SRS currently used for beam management operates as follows:

[0128] When each SRS within the SRS resource set is configured with a TCI state, the terminal determines the transmission beam direction of the SRS based on the reference signal (RS) of Quasi Co-Located type D indicated by the TCI state. In this case, the transmission beams of different SRS resources can be made the same or different through the configuration of the TCI state.

[0129] When at least one SRS in the SRS resource set is configured with a TCI state and at least one SRS is not configured with a TCI state, the transmission beam direction of the SRS without a TCI state is obtained as follows: refer to the QCL type D RS of the TCI state of the SRS with the lowest SRS ID among all SRSs in the set that are configured with a TCI state, and determine the transmission beam direction of that SRS.

[0130] When the SRS transmit beams within the configured SRS resource set are different, they can be used to determine the optimal transmit beam direction for the terminal and the optimal receive beam direction for the base station; when the configured SRS transmit beams are the same, they can be used to determine the optimal receive beam direction for the base station.

[0131] See Figure 1 , Figure 1 This is a schematic diagram of the transmission beam direction of SRS in related technologies, such as... Figure 1As shown, the network device configures one SRS resource set for the terminal. The SRS resource set includes four SRS resources. The four SRS resources correspond to different uplink transmission beams, or the four SRS resources correspond to the same uplink transmission beam.

[0132] Currently, the QCL RS of type D in TCI state can be a downlink synchronization signal block (SSB) or a channel state information reference signal (CSI-RS), or an uplink SRS used for beam management.

[0133] See Figure 2 , Figure 2 This is a schematic diagram of a transmission and reception point that only performs uplink operations in related technologies, such as... Figure 2 As shown in Figure 2, the new scenario aims to increase uplink coverage performance. Uplink services are provided to terminals by deploying uplink-only (UL-only) Transmission Reception Points (TRPs) in the network. This is a decoupled uplink / downlink transmission scenario. The terminal's downlink channels and signals, such as SSB, Physical Downlink Control Channel (PDCCH), and Physical Downlink Shared Channel (PDSCH), all originate from a single downlink (DL) TRP. However, uplink channels and signals, such as Physical Uplink Control Channel (PUCCH), Physical Uplink Shared Channel (PUSCH), and SRS (for Codebook Based, Non-Codebook Based, and Beam Management), are sent to the UL-only TRP.

[0134] For the uplink channel, since the UL-only TRP has no downlink SSB and CSI-RS reference signals, the terminal can only determine the optimal uplink transmit beam direction based on the SRS used for beam management and configure the SRS as a Type D QCL RS in the UL TCI state to indicate the uplink transmit beam direction of the PUCCH, PUSCH and other SRS for other purposes.

[0135] However, the resulting technical problem is that the QCL RS for type D in the current TCI state can be a downlink SSB or CSI-RS, or an uplink SRS used for beam management. In the UL-only scenario, the UL TRP does not have an SSB or CSI-RS. Therefore, the QCL RS for type D in the TCI state can only be an uplink SRS used for beam management.

[0136] When the terminal first begins transmitting the SRS for beam management, the base station does not know which beam direction channel is better, and therefore cannot determine which SRS resource for beam management can be used as a Type D QCL RS of the TCI state of the PUCCH or PUSCH. At this time, how to determine the transmit beam of the SRS for beam management, so as to determine the optimal transmit beam direction for the terminal and the optimal receive beam direction for the base station, is a problem that needs to be solved.

[0137] See Figure 3 , Figure 3 This is a schematic diagram illustrating the implementation flow of the configuration method in an embodiment of this application, applied to a terminal, such as... Figure 3 As shown, the method includes steps 301 to 302:

[0138] Step 301: Receive a first parameter configured by the network device for the SRS resource set, and / or receive a second parameter configured by the network device for the SRS resources in the SRS resource set; wherein, the first parameter represents that different SRS resources in the SRS resource set correspond to the same or different uplink spatial domain filtering or uplink spatial relationship, and the second parameter is related to the repeated transmission of SRS resources.

[0139] Step 302: Receive a third parameter configured by the network device for the SRS resource set, and receive a fourth parameter configured by the network device for the SRS resource group in the SRS resource set; wherein, the third parameter indicates that different SRS resource groups in the SRS resource set correspond to the same or different uplink spatial domain filtering or uplink spatial relationships, and the fourth parameter indicates that different SRS resources within the SRS resource group in the SRS resource set correspond to the same or different uplink spatial domain filtering or uplink spatial relationships.

[0140] It should be noted that in this application, steps 301 and 302 can be performed simultaneously, or either step can be performed.

[0141] In some embodiments, the first parameter is configured to be disabled; wherein, the disabling indicates that different SRS resources in the SRS resource set correspond to different uplink spatial domain filtering or uplink spatial relationships; or...

[0142] The first parameter is configured to be enabled; wherein, being enabled means that different SRS resources in the SRS resource set correspond to the same uplink spatial domain filtering or uplink spatial relationship.

[0143] It is understood that the uplink spatial domain filtering or uplink spatial relationship may refer to the uplink transmission beam.

[0144] It is understood that the "disable" means that different SRS resources in the SRS resource set correspond to different uplink spatial domain filters or uplink spatial relationships, or it can be described as different SRS resources in the SRS resource set corresponding to different uplink transmission beams.

[0145] It is understood that "enabled" means that different SRS resources in the SRS resource set correspond to the same uplink spatial domain filtering or uplink spatial relationship, or it can be described as different SRS resources in the SRS resource set corresponding to the same uplink transmission beam.

[0146] It is understandable that the first parameter is configured to be disabled, which can be represented as Repetition=off, where the first parameter is represented by Repetition.

[0147] It is understandable that the first parameter is configured to be enabled, which can be expressed as Repetition=on, where the first parameter is represented by Repetition.

[0148] It is understandable that Repetition = off indicates that the uplink transmission beams of different SRS resources in the SRS resource set are different, or it can be described as that the uplink spatial domain filtering or uplink spatial relationship of different SRS resources in the SRS resource set is different.

[0149] It is understandable that Repetition=on indicates that the uplink transmission beams of different SRS resources in the SRS resource set are the same, or it can be described as that the uplink spatial domain filtering or uplink spatial relationship of different SRS resources in the SRS resource set is the same.

[0150] In some embodiments, the method further includes:

[0151] The protection interval reserved between different SRS resources configured in the receiving network device.

[0152] Understandably, when the first parameter of a network device configuration is disabled (Repetition = off), a protection interval needs to be reserved between different SRS resources, which can be represented by Gap. Gap consists of N predefined or configured symbols, where N is an integer greater than or equal to 0. The purpose of Gap is to reserve time between uplink transmission beam directions during terminal handover. Furthermore, the value of Gap can also depend on the terminal's capabilities.

[0153] In some embodiments, the first parameter configured by the receiving network device for the SRS resource set includes:

[0154] The first parameter indicated by the network device is received by one of the following:

[0155] DCI;

[0156] MAC CE;

[0157] RRC.

[0158] It is understood that the network device may indicate a first parameter configured via DCI, MAC CE, or RRC, wherein the first parameter may be represented by Repetition.

[0159] In some embodiments, the method further includes:

[0160] Receive first indication information sent by the network device; wherein, the first indication information is used to indicate a reference signal of type D of the TCL state of the SRS resource in the SRS resource set;

[0161] Based on the reference signal, determine the uplink spatial domain filtering or uplink spatial relationship of the SRS signal of the SRS resource.

[0162] It is understood that the uplink spatial domain filtering or uplink spatial relationship may refer to the uplink transmission beam.

[0163] It is understood that when the network device configures the first parameter of the SRS resource set to be enabled, it may additionally indicate the reference signal (RS) of the QCL type (type) D of the TCI state of the SRS resource in the SRS resource set.

[0164] Here, the QCL type D of the TCI state is used to indicate the spatial parameters of the terminal beam, i.e., the beam direction information.

[0165] It should be noted that in UL-only TRP scenarios, since UL TRP does not involve SSB and CSI-RS, the RS of type D in TCI status can only be the uplink SRS used for beam management.

[0166] It is understood that when determining the uplink transmission beam (or described as uplink spatial domain filtering or uplink spatial relationship) of the SRS signal of the SRS resource in the SRS resource set based on the reference signal (RS) of the QCL type (type D) of the TCI state, the uplink transmission beam of the SRS signal of the SRS resource corresponds to the uplink transmission beam (or described as uplink spatial domain filtering or uplink spatial relationship) of the most recent transmission timing of the RS. The uplink transmission beam of the most recent transmission timing of the RS can refer to the uplink transmission beam corresponding to the optimal transmission beam direction of the terminal.

[0167] It should be noted that when the terminal initially transmits SRS for beam management, the network device does not know which beam direction channel is better, and therefore cannot determine which SRS resource for beam management can be used as a Type D QCL RS of the TCI state of PUCCH or PUSCH. At this time, the network device can configure the first parameter to be disabled. The disabled parameter indicates that different SRS resources in the SRS resource set correspond to different uplink spatial domain filtering or uplink spatial relationships, meaning different SRS resources use different uplink transmission beams to transmit SRS. After several cycles of measurement, the network device determines the optimal terminal transmission beam direction. Then, the network device can configure the first parameter to be enabled. The enabled parameter indicates that different SRS resources in the SRS resource set correspond to the same uplink spatial domain filtering or uplink spatial relationship, meaning different SRS resources use the same uplink transmission beam to transmit SRS. This same uplink transmission beam is indicated by the reference signal of the Type D of the TCL state, specifically the uplink transmission beam corresponding to the terminal's optimal transmission beam direction.

[0168] See Figure 4 , Figure 4 This is a schematic diagram of the terminal sending SRS according to an embodiment of this application, as shown below. Figure 4As shown, the network device configures one SRS resource set via RRC, which includes four SRS resources, denoted as {SRS1, SRS2, SRS3, SRS4}. The purpose of the SRS resource set is beam management. The first parameter of the SRS resource set is configured to be disabled via DCI, MAC CE, or RRC, i.e., Repetition = off. This means that the four SRS resources in the SRS resource set use different uplink transmission beams to transmit SRS, that is, the four SRS resources correspond to different uplink spatial domain filtering or uplink spatial relationships. After determining the optimal terminal transmit beam direction through several cycles of measurement, the network device can update the configuration of the first parameter of the SRS resource set to enabled via DCI, MAC CE, or RRC, i.e., Repetition is updated to on. This indicates that the four SRS resources in the SRS resource set are transmitted using the same uplink transmit beam, meaning that the four SRS resources correspond to the same uplink spatial domain filtering or uplink spatial relationship. It also indicates that the reference signal (RS) of the QCL type D of the TCI state of the SRS resources in the SRS resource set is SRS2. Here, SRS2 is the uplink reference signal transmitted with the uplink transmit beam corresponding to the optimal transmit beam direction of the terminal. At this time, the four SRS resources are transmitted with the same transmit beam, which is used by the network device, such as the base station, to determine the optimal receive beam direction on the base station side.

[0169] In practical applications, the terminal can receive the first parameter configured by the network device for the SRS resource set, and / or receive the second parameter configured by the network device for the SRS resources in the SRS resource set.

[0170] Based on this, in some embodiments, the second parameter is configured as a first value; wherein the first value is used to indicate the number of times each SRS resource is repeatedly transmitted.

[0171] Understandably, the second parameter can be represented by repetitionFactor.

[0172] For example, the second parameter, the repetitionFactor parameter, can take values ​​in the range of {n1, n2, n4}, where n1 represents that the SRS resource is transmitted in the time domain for 1 symbol, i.e., it is not transmitted repeatedly; n2 represents that the SRS resource is transmitted repeatedly for 2 consecutive symbols in the time domain; and n4 represents that the SRS resource is transmitted repeatedly for 4 consecutive symbols in the time domain.

[0173] In some embodiments, receiving the second parameter configured by the network device for SRS resources in the SRS resource set includes:

[0174] The second parameter indicated by the network device is received through one of the following:

[0175] DCI;

[0176] MAC CE;

[0177] RRC.

[0178] It is understood that the network device may indicate a second parameter configured via MAC CE, DCI, or RRC, wherein the second parameter may be represented by the repetitionFactor parameter.

[0179] The following explanation uses the example of a terminal receiving the first parameter and the second parameter.

[0180] It is understood that the network device can configure an SRS resource set for the terminal, the SRS resource set including N SRS resources, where N is an integer greater than 1, configure a first parameter, namely the Repetition parameter, for the SRS resource set, and configure a second parameter, namely the repetitionFactor parameter, for each SRS resource. The second parameter, namely the repetitionFactor parameter, is indicated through MAC CE, DCI, or RRC.

[0181] It is understandable that the first parameter is configured to be disabled, which can be represented as Repetition=off, where the first parameter is represented by Repetition.

[0182] It is understandable that the first parameter is configured to be enabled, which can be expressed as Repetition=on, where the first parameter is represented by Repetition.

[0183] It is understandable that Repetition = off indicates that the uplink transmission beams of different SRS resources in the SRS resource set are different, or it can be described as that the uplink spatial domain filtering or uplink spatial relationship of different SRS resources in the SRS resource set is different.

[0184] It is understandable that Repetition=on indicates that the uplink transmission beams of different SRS resources in the SRS resource set are the same, or it can be described as that the uplink spatial domain filtering or uplink spatial relationship of different SRS resources in the SRS resource set is the same.

[0185] Understandably, when the first parameter of a network device configuration is disabled (Repetition = off), a protection interval needs to be reserved between different SRS resources, which can be represented by Gap. Gap consists of N predefined or configured symbols, where N is an integer greater than or equal to 0. The purpose of Gap is to reserve time between uplink transmission beam directions during terminal handover. Furthermore, the value of Gap can also depend on the terminal's capabilities.

[0186] It should be noted that when the terminal first sends the SRS for beam management, the network device does not know which beam direction channel is better, and therefore cannot determine which SRS resource for beam management can be used as the Type D QCL RS of the TCI state of PUCCH or PUSCH. At this time, the network device can configure the first parameter to be disabled and the second parameter to a first value. The disabled parameter indicates that different SRS resources in the SRS resource set correspond to different uplink spatial domain filtering or uplink spatial relationships, that is, different SRS resources use different uplink transmission beams to transmit SRS. The first value can be n2 or n4, etc., where n2 or n4 is used to indicate the number of times each SRS resource is repeatedly transmitted. After the network device determines the optimal terminal transmission beam direction through several cycles of measurement, the network device can configure the first parameter to be enabled and the second parameter to a first value. The enabled parameter indicates that different SRS resources in the SRS resource set correspond to the same uplink spatial domain filtering or uplink spatial relationship, that is, different SRS resources use the same uplink transmission beam to transmit SRS. The same uplink transmission beam is indicated by the reference signal of type D of TCL state, which can be the uplink transmission beam corresponding to the optimal transmission beam direction of the terminal. The first value can be n1, where n1 is used to indicate that each SRS resource is not repeatedly transmitted.

[0187] The beneficial effect that can be achieved here is that when network devices such as base stations find that the quality of certain transmission beam directions of the terminal is not good through measurement and it is unnecessary to continue transmitting, they can use MAC CE or DCI or RRC to indicate the second parameter configured to deactivate the repeated transmission of the SRS resources, thereby saving SRS resource overhead.

[0188] See Figure 5 , Figure 5 This is a schematic diagram of the terminal sending SRS according to an embodiment of this application, as shown below. Figure 5As shown, the network configures one SRS resource set via RRC, including two SRS resources. For each SRS resource, the second parameter is configured to the first value, i.e., repetitionFactor = n2, where n2 represents that each SRS resource is repeatedly transmitted within two consecutive symbols, i.e., retransmitted twice. The purpose of this SRS resource set is beam management. The first parameter of the SRS resource set is configured to be disabled via RRC, i.e., Repetition = off, meaning that different SRS resources within the SRS resource set use different transmission beams to transmit SRS, that is, the two SRS resources correspond to different uplink spatial domain filtering or uplink spatial relationships. After several cycles of measurement, the network determines the optimal terminal transmit beam and base station receive beam pair. Then, the configuration of the second parameter of each SRS resource can be updated via DCI, MAC CE, or RCC, i.e., repetitionFactor = n1, where n1 indicates that each SRS resource is not repeatedly transmitted, thereby saving uplink resource overhead.

[0189] In practical applications, the terminal can receive a third parameter configured by the network device for the SRS resource set, and a fourth parameter configured by the network device for the SRS resource group in the SRS resource set.

[0190] Based on this, in some embodiments, the third parameter is configured to be disabled; wherein, the disabling indicates that different SRS resource groups in the SRS resource set correspond to different uplink spatial domain filtering or uplink spatial relationships; or...

[0191] The third parameter is configured to be enabled; wherein, being enabled means that different SRS resource groups in the SRS resource set correspond to the same uplink spatial domain filtering or uplink spatial relationship.

[0192] It is understood that the uplink spatial domain filtering or uplink spatial relationship may refer to the uplink transmission beam.

[0193] It is understood that the "disable" means that different SRS resource groups in the SRS resource set correspond to different uplink spatial domain filtering or uplink spatial relationships, or it can be described as different uplink transmission beams corresponding to different SRS resource groups in the SRS resource set.

[0194] It is understood that "enabled" means that different SRS resource groups in the SRS resource set correspond to the same uplink spatial domain filtering or uplink spatial relationship, or it can be described as different SRS resource groups in the SRS resource set corresponding to the same uplink transmission beam.

[0195] It is understood that the network device can configure an SRS resource set for the terminal and group the SRS resources within the SRS resource set. Specifically, SRS resources can be grouped according to antenna ports; for example, single-port antennas can form one SRS resource group, and dual-port antennas can form another. Other grouping methods can also be used in practical applications, and this application does not limit them.

[0196] It is understood that the third parameter configured by the network device for the SRS resource set can be represented by Repetition. When the third parameter is configured to be disabled, it can be expressed as Repetition=off, which means that different SRS resource groups in the SRS resource set use different uplink transmission beams (or uplink spatial domain filtering, or uplink spatial relationships). When the third parameter is configured to be enabled, it can be expressed as Repetition=on, which means that different SRS resource groups in the SRS resource set use the same uplink transmission beam (or uplink spatial domain filtering, or uplink spatial relationship).

[0197] In some embodiments, the third parameter configured by the receiving network device for the SRS resource set includes:

[0198] The third parameter indicated by the network device is received through one of the following:

[0199] DCI;

[0200] MAC CE;

[0201] RRC.

[0202] In some embodiments, the method further includes:

[0203] The network device receives the protection intervals reserved between different SRS resource groups configured by the network device.

[0204] Understandably, a protection interval, denoted as Gap, needs to be reserved between different SRS resource groups. The Gap value is a predefined or configured set of N symbols, where N is an integer greater than or equal to 0. The purpose of Gap is to reserve time between uplink beam directions during terminal handover. Additionally, the value of Gap can also depend on the terminal's capabilities.

[0205] In some embodiments, the fourth parameter is configured to be disabled; wherein, the disabling indicates that different SRS resources within the SRS resource group of the SRS resource set correspond to different uplink spatial domain filtering or uplink spatial relationships; or...

[0206] The fourth parameter is configured to be enabled; wherein, being enabled means that different SRS resources within the SRS resource group in the SRS resource set correspond to the same uplink spatial domain filtering or uplink spatial relationship.

[0207] It is understood that the uplink spatial domain filtering or uplink spatial relationship may refer to the uplink transmission beam.

[0208] It is understood that the "disable" means that different SRS resources within the SRS resource group in the SRS resource set correspond to different uplink spatial domain filtering or uplink spatial relationships, or it can be described as different uplink transmission beams corresponding to different SRS resources within the SRS resource group in the SRS resource set.

[0209] It is understood that the "enable" means that different SRS resources within the SRS resource group in the SRS resource set correspond to the same uplink spatial domain filtering or uplink spatial relationship, or it can be described as different SRS resources within the SRS resource group in the SRS resource set corresponding to the same uplink transmission beam.

[0210] It is understood that the network device can configure an SRS resource set for the terminal, group the SRS resources within the SRS resource set, and configure a fourth parameter for each SRS resource group. The fourth parameter can be represented by Repetition. When the fourth parameter is configured to be disabled, it can be expressed as Repetition=off, which means that the SRS resources in each SRS resource group use different uplink transmission beams (or described as uplink spatial domain filtering or uplink spatial relationships). When the fourth parameter is configured to be enabled, it can be expressed as Repetition=on, which means that the SRS resources in each SRS resource group use the same uplink transmission beam (or described as uplink spatial domain filtering or uplink spatial relationships).

[0211] In some embodiments, receiving the fourth parameter configured by the network device for the SRS resource group in the SRS resource set includes:

[0212] The fourth parameter indicated by the network device is received by one of the following:

[0213] DCI;

[0214] MAC CE;

[0215] RRC.

[0216] In some embodiments, the method further includes:

[0217] Receive a second indication message sent by the network device through one of the following:

[0218] DCI;

[0219] MAC CE;

[0220] RRC;

[0221] The second indication information is used to indicate whether to activate or deactivate the SRS resource group in the SRS resource set.

[0222] That is, the network device can activate or deactivate some SRS resource groups via MAC CE, DCI, or RRC.

[0223] It is understandable that activating an SRS resource group means that the SRS resources within that SRS resource group can send SRS signals.

[0224] It is understandable that deactivating an SRS resource group means that the SRS resources within that SRS resource group cannot send SRS signals.

[0225] It is understandable that a deactivated SRS resource group can refer to an SRS resource group whose SRS signal quality is less than or equal to a preset threshold.

[0226] The beneficial effect that can be achieved here is that when network devices such as base stations find that the quality of certain transmission beam directions of the terminal is poor through measurement and it is unnecessary to continue transmitting, the SRS resource group can be activated through MAC CE, DCI or RRC to save SRS resource overhead.

[0227] It should be noted that when the terminal initially transmits SRS for beam management, the network device does not know which beam direction channel is better, and therefore cannot determine which SRS resource for beam management can be used as a Type D QCL RS of the TCI state of PUCCH or PUSCH. At this time, the network device can configure the third parameter to be disabled and the fourth parameter to be enabled. The disabled parameter indicates that different SRS resource groups in the SRS resource set correspond to different uplink spatial domain filtering or uplink spatial relationships, meaning different SRS resource groups use different uplink transmission beams to transmit SRS. The enabled parameter indicates that different SRS resources within the SRS resource group in the SRS resource set correspond to the same uplink spatial domain filtering or uplink spatial relationship, meaning different SRS resources within the SRS resource group use the same uplink transmission beam to transmit SRS. After several cycles of measurement, once the network device determines the optimal terminal transmission beam direction, it can instruct the deactivation of some SRS resource groups to save SRS resource overhead.

[0228] Alternatively, when the terminal first begins transmitting SRS for beam management, the network device does not know which beam direction channel is better, and therefore cannot determine which SRS resource for beam management can be used as a Type D QCL RS of the TCIstate of PUCCH or PUSCH. In this case, the network device can configure the third parameter to be enabled and the fourth parameter to be disabled. Enabling indicates that different SRS resource groups in the SRS resource set correspond to the same uplink spatial domain filtering or uplink spatial relationship, meaning different SRS resource groups use the same uplink transmission beam to transmit SRS. Disabling indicates that different SRS resources within the SRS resource group in the SRS resource set correspond to different uplink spatial domain filtering or uplink spatial relationships, meaning different SRS resources within the SRS resource group use different uplink transmission beams to transmit SRS. After several cycles of measurement, once the network device determines the optimal terminal transmission beam direction, it can instruct the deactivation of some SRS resource groups to save SRS resource overhead.

[0229] See Figure 6 , Figure 6 This is a schematic diagram of the terminal sending SRS according to an embodiment of this application, as shown below. Figure 6 As shown, the network device configures one SRS resource set via RRC. This SRS resource set includes two SRS resource groups, denoted as SRS resource group 1 and SRS resource group 2. Each SRS resource group includes two SRS resources: SRS resource group 1 includes {SRS1, SRS2}, and SRS resource group 2 includes {SRS3, SRS4}. The purpose of the SRS resource set is beam management. The network device configures the fourth parameter of the SRS resource groups in the SRS resource set, i.e., Repetition = on, via MAC CE, DCI, or RRC, indicating that different SRS resources within the SRS resource group use the same transmission beam. The third parameter of the SRS resource set is disabled via MAC CE, DCI, or RRC, i.e., Repetition = off, indicating that different SRS resource groups within the SRS resource set use different transmission beams to transmit SRS. After the network determines the optimal terminal transmission beam direction through several cycles of measurement, it can activate some SRS resource groups through DCI, MAC CE, or RRC. The quality of the SRS signal transmitted by the SRS resources in the activated SRS resource group is less than or equal to a preset threshold, saving uplink resource overhead.

[0230] In some embodiments, the method further includes:

[0231] Receive the SRS resource set configured by the network device via RRC signaling.

[0232] It is understood that the network device can configure one or more SRS resource sets for the terminal through RRC signaling, and the SRS resource set may include N SRS resources, where N is an integer greater than or equal to 1.

[0233] The embodiments of this application have the following technical advantages:

[0234] (1) The uplink transmission beam used by the terminal to transmit SRS is indicated by the first parameter and / or the second parameter, and / or by the third parameter and the fourth parameter. Thus, in a UL only TR scenario, if the network device cannot determine which SRS resource can be used to indicate the Transmission Configuration Indication TCI status, the uplink transmission beam used by the terminal to transmit SRS is indicated by the first parameter and / or the second parameter, and / or by the third parameter and the fourth parameter.

[0235] Furthermore, when the configured uplink transmit beams are different, they can be used to determine the optimal transmit beam direction for the terminal and the optimal receive beam direction for the base station; when the configured uplink transmit beams are the same, they can be used to determine the optimal receive beam direction for the base station.

[0236] This application proposes an uplink SRS beam management mechanism, which helps to improve uplink beam management efficiency, save uplink resources, and improve the uplink communication performance of the base station.

[0237] See Figure 7 , Figure 7 This is a schematic diagram illustrating the implementation flow of the configuration method in an embodiment of this application, applied to network devices, such as... Figure 7 As shown, the method includes steps 701 to 702:

[0238] Step 701: Configure a first parameter for the SRS resource set, and / or configure a second parameter for the SRS resources in the SRS resource set; wherein, the first parameter represents that different SRS resources in the SRS resource set correspond to the same or different uplink spatial domain filtering or uplink spatial relationship, and the second parameter is related to the repeated transmission of SRS resources;

[0239] Step 702: Configure a third parameter for the SRS resource set, and configure a fourth parameter for the SRS resource groups in the SRS resource set; wherein, the third parameter represents that different SRS resource groups in the SRS resource set correspond to the same or different uplink spatial domain filtering or uplink spatial relationships, and the fourth parameter represents that different SRS resources within the SRS resource groups in the SRS resource set correspond to the same or different uplink spatial domain filtering or uplink spatial relationships.

[0240] It should be noted that in this application, steps 701 and 702 can be performed simultaneously, or either step can be performed.

[0241] In some embodiments, the first parameter is configured to be disabled; wherein, the disabling indicates that different SRS resources in the SRS resource set correspond to different uplink spatial domain filtering or uplink spatial relationships; or...

[0242] The first parameter is configured to be enabled; wherein, being enabled means that different SRS resources in the SRS resource set correspond to the same uplink spatial domain filtering or uplink spatial relationship.

[0243] It is understood that the uplink spatial domain filtering or uplink spatial relationship may refer to the uplink transmission beam.

[0244] It is understood that the "disable" means that different SRS resources in the SRS resource set correspond to different uplink spatial domain filters or uplink spatial relationships, or it can be described as different SRS resources in the SRS resource set corresponding to different uplink transmission beams.

[0245] It is understood that "enabled" means that different SRS resources in the SRS resource set correspond to the same uplink spatial domain filtering or uplink spatial relationship, or it can be described as different SRS resources in the SRS resource set corresponding to the same uplink transmission beam.

[0246] It is understandable that the first parameter is configured to be disabled, which can be represented as Repetition=off, where the first parameter is represented by Repetition.

[0247] It is understandable that the first parameter is configured to be enabled, which can be expressed as Repetition=on, where the first parameter is represented by Repetition.

[0248] It is understandable that Repetition = off indicates that the uplink transmission beams of different SRS resources in the SRS resource set are different, or it can be described as that the uplink spatial domain filtering or uplink spatial relationship of different SRS resources in the SRS resource set is different.

[0249] It is understandable that Repetition=on indicates that the uplink transmission beams of different SRS resources in the SRS resource set are the same, or it can be described as that the uplink spatial domain filtering or uplink spatial relationship of different SRS resources in the SRS resource set is the same.

[0250] In some embodiments, the method further includes:

[0251] Configure the protection intervals reserved between different SRS resources.

[0252] Understandably, when the first parameter of a network device configuration is disabled (Repetition = off), a protection interval needs to be reserved between different SRS resources, which can be represented by Gap. Gap consists of N predefined or configured symbols, where N is an integer greater than or equal to 0. The purpose of Gap is to reserve time between uplink transmission beam directions during terminal handover. Furthermore, the value of Gap can also depend on the terminal's capabilities.

[0253] In some embodiments, configuring the first parameter for the SRS resource set includes:

[0254] The first parameter can be indicated to the terminal by one of the following:

[0255] DCI;

[0256] MAC CE;

[0257] RRC.

[0258] In some embodiments, the method further includes:

[0259] Send a first indication message to the terminal; wherein the first indication message is used to indicate a reference signal of type D of the TCL state of the SRS resource in the SRS resource set; the reference signal is used by the terminal to determine the uplink spatial domain filtering or uplink spatial relationship of the SRS signal of the SRS resource.

[0260] It is understood that the uplink spatial domain filtering or uplink spatial relationship may refer to the uplink transmission beam.

[0261] It is understood that when the network device configures the first parameter of the SRS resource set to be enabled, it may additionally indicate the reference signal (RS) of the QCL type (type) D of the TCI state of the SRS resource in the SRS resource set.

[0262] Here, the QCL type D of the TCI state is used to indicate the spatial parameters of the terminal beam, i.e., the beam direction information.

[0263] It should be noted that in UL-only TRP scenarios, since UL TRP does not involve SSB and CSI-RS, the RS of type D in TCI status can only be the uplink SRS used for beam management.

[0264] It is understood that when determining the uplink transmission beam (or described as uplink spatial domain filtering or uplink spatial relationship) of the SRS signal of the SRS resource in the SRS resource set based on the reference signal (RS) of the QCL type (type D) of the TCI state, the uplink transmission beam of the SRS signal of the SRS resource corresponds to the uplink transmission beam (or described as uplink spatial domain filtering or uplink spatial relationship) of the most recent transmission timing of the RS. The uplink transmission beam of the most recent transmission timing of the RS can refer to the uplink transmission beam corresponding to the optimal transmission beam direction of the terminal.

[0265] It should be noted that when the terminal initially transmits SRS for beam management, the network device does not know which beam direction channel is better, and therefore cannot determine which SRS resource for beam management can be used as a Type D QCL RS of the TCI state of PUCCH or PUSCH. At this time, the network device can configure the first parameter to be disabled. The disabled parameter indicates that different SRS resources in the SRS resource set correspond to different uplink spatial domain filtering or uplink spatial relationships, meaning different SRS resources use different uplink transmission beams to transmit SRS. After several cycles of measurement, the network device determines the optimal terminal transmission beam direction. Then, the network device can configure the first parameter to be enabled. The enabled parameter indicates that different SRS resources in the SRS resource set correspond to the same uplink spatial domain filtering or uplink spatial relationship, meaning different SRS resources use the same uplink transmission beam to transmit SRS. This same uplink transmission beam is indicated by the reference signal of the Type D of the TCL state, specifically the uplink transmission beam corresponding to the terminal's optimal transmission beam direction.

[0266] In practical applications, the terminal can receive the first parameter configured by the network device for the SRS resource set, and / or receive the second parameter configured by the network device for the SRS resources in the SRS resource set.

[0267] Based on this, in some embodiments, the second parameter is configured as a first value; wherein the first value is used to indicate the number of times each SRS resource is repeatedly transmitted.

[0268] Understandably, the second parameter can be represented by repetitionFactor.

[0269] For example, the second parameter, the repetitionFactor parameter, can take values ​​in the range of {n1, n2, n4}, where n1 represents that the SRS resource is transmitted in the time domain for 1 symbol, i.e., it is not transmitted repeatedly; n2 represents that the SRS resource is transmitted repeatedly for 2 consecutive symbols in the time domain; and n4 represents that the SRS resource is transmitted repeatedly for 4 consecutive symbols in the time domain.

[0270] In some embodiments, configuring a second parameter for SRS resources in the SRS resource set includes:

[0271] The second parameter can be indicated to the terminal through one of the following:

[0272] DCI;

[0273] MAC CE;

[0274] RRC.

[0275] In practical applications, the terminal can receive a third parameter configured by the network device for the SRS resource set, and a fourth parameter configured by the network device for the SRS resource group in the SRS resource set.

[0276] Based on this, in some embodiments, the third parameter is configured to be disabled; wherein, the disabling indicates that different SRS resource groups in the SRS resource set correspond to different uplink spatial domain filtering or uplink spatial relationships; or...

[0277] The third parameter is configured to be enabled; wherein, being enabled means that different SRS resource groups in the SRS resource set correspond to the same uplink spatial domain filtering or uplink spatial relationship.

[0278] It is understood that the uplink spatial domain filtering or uplink spatial relationship may refer to the uplink transmission beam.

[0279] It is understood that the "disable" means that different SRS resource groups in the SRS resource set correspond to different uplink spatial domain filtering or uplink spatial relationships, or it can be described as different uplink transmission beams corresponding to different SRS resource groups in the SRS resource set.

[0280] It is understood that "enabled" means that different SRS resource groups in the SRS resource set correspond to the same uplink spatial domain filtering or uplink spatial relationship, or it can be described as different SRS resource groups in the SRS resource set corresponding to the same uplink transmission beam.

[0281] It is understood that the network device can configure an SRS resource set for the terminal and group the SRS resources within the SRS resource set. Specifically, SRS resources can be grouped according to antenna ports; for example, single-port antennas can form one SRS resource group, and dual-port antennas can form another. Other grouping methods can also be used in practical applications, and this application does not limit them.

[0282] It is understood that the third parameter configured by the network device for the SRS resource set can be represented by Repetition. When the third parameter is configured to be disabled, it can be expressed as Repetition=off, which means that different SRS resource groups in the SRS resource set use different uplink transmission beams (or uplink spatial domain filtering, or uplink spatial relationships). When the third parameter is configured to be enabled, it can be expressed as Repetition=on, which means that different SRS resource groups in the SRS resource set use the same uplink transmission beam (or uplink spatial domain filtering, or uplink spatial relationship).

[0283] In some embodiments, the method further includes:

[0284] Configure the protection intervals reserved between different SRS resource groups.

[0285] Understandably, a protection interval, denoted as Gap, needs to be reserved between different SRS resource groups. The Gap value is a predefined or configured set of N symbols, where N is an integer greater than or equal to 0. The purpose of Gap is to reserve time between uplink beam directions during terminal handover. Additionally, the value of Gap can also depend on the terminal's capabilities.

[0286] In some embodiments, configuring a third parameter for the SRS resource set includes:

[0287] The third parameter can be indicated to the terminal through one of the following:

[0288] DCI;

[0289] MAC CE;

[0290] RRC.

[0291] In some embodiments, the fourth parameter is configured to be disabled; wherein, the disabling indicates that different SRS resources within the SRS resource group of the SRS resource set correspond to different uplink spatial domain filtering or uplink spatial relationships; or...

[0292] The fourth parameter is configured to be enabled; wherein, being enabled means that different SRS resources within the SRS resource group in the SRS resource set correspond to the same uplink spatial domain filtering or uplink spatial relationship.

[0293] It is understood that the uplink spatial domain filtering or uplink spatial relationship may refer to the uplink transmission beam.

[0294] It is understood that the "disable" means that different SRS resources within the SRS resource group in the SRS resource set correspond to different uplink spatial domain filtering or uplink spatial relationships, or it can be described as different uplink transmission beams corresponding to different SRS resources within the SRS resource group in the SRS resource set.

[0295] It is understood that the "enable" means that different SRS resources within the SRS resource group in the SRS resource set correspond to the same uplink spatial domain filtering or uplink spatial relationship, or it can be described as different SRS resources within the SRS resource group in the SRS resource set corresponding to the same uplink transmission beam.

[0296] It is understood that the network device can configure an SRS resource set for the terminal, group the SRS resources within the SRS resource set, and configure a fourth parameter for each SRS resource group. The fourth parameter can be represented by Repetition. When the fourth parameter is configured to be disabled, it can be expressed as Repetition=off, which means that the SRS resources in each SRS resource group use different uplink transmission beams (or described as uplink spatial domain filtering or uplink spatial relationships). When the fourth parameter is configured to be enabled, it can be expressed as Repetition=on, which means that the SRS resources in each SRS resource group use the same uplink transmission beam (or described as uplink spatial domain filtering or uplink spatial relationships).

[0297] In some embodiments, configuring a fourth parameter for the SRS resource group in the SRS resource set includes:

[0298] The fourth parameter can be indicated to the terminal through one of the following:

[0299] DCI;

[0300] MAC CE;

[0301] RRC.

[0302] In some embodiments, the method further includes:

[0303] Send a second instruction message to the terminal using one of the following methods:

[0304] DCI;

[0305] MAC CE;

[0306] RRC;

[0307] The second indication information is used to indicate whether to activate or deactivate the SRS resource group in the SRS resource set.

[0308] That is, the network device can activate or deactivate some SRS resource groups via MAC CE, DCI, or RRC.

[0309] It is understandable that activating an SRS resource group means that the SRS resources within that SRS resource group can send SRS signals.

[0310] It is understandable that deactivating an SRS resource group means that the SRS resources within that SRS resource group cannot send SRS signals.

[0311] It is understandable that a deactivated SRS resource group can refer to an SRS resource group whose SRS signal quality is less than or equal to a preset threshold.

[0312] The beneficial effect that can be achieved here is that when network devices such as base stations find that the quality of certain transmission beam directions of the terminal is poor through measurement and it is unnecessary to continue transmitting, the SRS resource group can be activated through MAC CE, DCI or RRC to save SRS resource overhead.

[0313] It should be noted that when the terminal initially transmits SRS for beam management, the network device does not know which beam direction channel is better, and therefore cannot determine which SRS resource for beam management can be used as a Type D QCL RS of the TCI state of PUCCH or PUSCH. At this time, the network device can configure the third parameter to be disabled and the fourth parameter to be enabled. The disabled parameter indicates that different SRS resource groups in the SRS resource set correspond to different uplink spatial domain filtering or uplink spatial relationships, meaning different SRS resource groups use different uplink transmission beams to transmit SRS. The enabled parameter indicates that different SRS resources within the SRS resource group in the SRS resource set correspond to the same uplink spatial domain filtering or uplink spatial relationship, meaning different SRS resources within the SRS resource group use the same uplink transmission beam to transmit SRS. After several cycles of measurement, once the network device determines the optimal terminal transmission beam direction, it can instruct the deactivation of some SRS resource groups to save SRS resource overhead.

Enabling indicates that different SRS resource groups in the SRS resource set correspond to the same uplink spatial domain filtering or uplink spatial relationship, meaning different SRS resource groups use the same uplink transmission beam to transmit SRS. Disabling indicates that different SRS resources within the SRS resource group in the SRS resource set correspond to different uplink spatial domain filtering or uplink spatial relationships, meaning different SRS resources within the SRS resource group use different uplink transmission beams to transmit SRS. After several cycles of measurement, once the network device determines the optimal terminal transmission beam direction, it can instruct the deactivation of some SRS resource groups to save SRS resource overhead.

[0315] In some embodiments, the method further includes:

[0316] Configure the SRS resource set for the terminal using RRC signaling.

[0317] It is understood that the network device can configure one or more SRS resource sets for the terminal through RRC signaling, and the SRS resource set may include N SRS resources, where N is an integer greater than or equal to 1.

[0318] The embodiments of this application have the following technical advantages:
