[0001] This application belongs to the field of communication technology, and specifically relates to a parameter determination method, apparatus and device. Background Technology
[0002] The R17 (Release 17) protocol for New Radio (NR) introduced the concept of a unified transmission configuration indicator framework (unified TCI framework).
[0003] The R17 unified TCI framework defines that network devices can indicate common beam information, such as joint transmission configuration indicator TCI state or separate UL TCI state, to terminal devices via downlink signaling to determine the common beam information of multiple channels or reference signals.
[0004] However, the common beam information indicated by the joint TCI state or separate ULTCI state, and the power control parameters included or associated with the common beam information, are used for multiple channels such as the physical uplink shared channel (PUSCH) and the physical uplink control channel (PUCCH). For the sounding reference signal (SRS), the R17 unified TCI framework currently does not provide a method for determining the configuration information such as the SRS beam information and power control parameters. Summary of the Invention

It should be noted that this application embodiment only uses a base station in an NR system as an example, but does not limit the specific type of base station.
[0023] Currently, when performing beam measurements, network devices configure a reference signal resource set (RS resource set), which includes at least one reference signal resource (RS resource), such as a synchronization signal and PBCH block (SSB) resource or a CSI reference signal (CSI-RS) resource. The UE measures the L1 reference signal received power (L1-RSRP) / L1 signal-to-noise and interference ratio (L1-SINR) for each RS resource and reports the best at least one measurement result to the network device.
[0024] After beam measurement and beam reporting, network devices can perform beam indication on downlink and uplink channels or reference signals to establish beam links between network devices and terminal devices, enabling the transmission of channels or reference signals.
[0025] Prior to R17, SRS beam indication employed three methods: When the SRS type was periodic SRS, network devices configured spatial relation information for SRS resources via radio resource control (RRC) signaling. When the SRS type was semi-persistent SRS or aperiodic SRS, network devices configured spatial relation information for SRS resources via RRC signaling and updated the spatial relation information of SRS resources using MAC CE commands.
[0026] In protocols prior to R17, the SRS power control parameters (also known as power control parameters) were determined as follows: For the path loss reference signal (PL-RS or PLRS), the PLRS configured by RRC was used, or the PLRS configured by RRC and updated by MAC CE was used. For the target received power P0, path loss compensation factor (α or alpha), closed-loop power control index or closed-loop index (CLI), etc., these were determined based on the parameters configured under each SRS resource set and could be updated or reconfigured via RRC.
[0027] The Release 17 (R17) protocol introduced the concept of a unified transport configuration indication framework. This framework establishes a Transport Configuration Indication (TCI) state pool and defines how network devices can indicate common beam information to terminal devices via MAC CE or downlink control information (DCI). This common beam information is used for multiple channels or reference signals and is selected by the network device from the TCI state pool. Specifically, this common beam information can be: joint TCI state, separate DL TCI state, or separate UL TCI state. The joint TCI state determines the beam information for user-specific control and data channels; the separate DL TCI state determines the beam information for downlink user-specific control and data channels; and the separate UL TCI state determines the beam information for uplink control and data channels.
[0028] The unified transport configuration instruction framework also defines how power control parameters are determined. For example, PLRS can be configured in or associated with a ULTCI state or a joint TCI state. For PUCCH or PUSCH, the set of power control parameters other than PLRS is associated with a ULTCI state or a joint TCI state.
[0029] However, the Unified Transmission Configuration Indication Framework currently does not specify whether the SRS adopts the aforementioned method for determining beam information and power control parameters; that is, it does not provide a method for determining configuration information such as SRS beam information and power control parameters. Therefore, this application proposes a parameter determination method, apparatus, and device, which provides a method for determining SRS beam information and SRS power control parameters within the Unified Transmission Configuration Indication Framework. It should be noted that the parameter determination method, apparatus, and device provided in this application are not limited to the R17 protocol and can also be applied to other protocols after R17.
[0030] It should be noted that the beam information mentioned in the embodiments of this application can also be referred to as: beam identification information, spatial relation information, spatial domain transmission filter information, spatial domain reception filter information, spatial filter information, transmission configuration indication state (TCI state) information, quasi-co-location (QCL) information, or QCL parameters, etc. Downlink beam information is typically represented using TCI state information or QCL information, while uplink beam information is typically represented using TCI state information or spatial relation information.
[0031] The parameter determination method, apparatus, and device provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.
[0032] like Figure 2 As shown, this application provides a parameter determination method. This parameter determination method can be applied to a terminal device. The parameter determination method may include the following step S201.
[0033] S201. In the unified transmission configuration indication framework, determine the configuration information of the SRS, which includes at least one of the beam information of the SRS and the power control parameter information of the SRS.
[0034] Optionally, the beam information of the SRS can be any of the following:
[0035] Uplink spatial filter for SRS resources
[0036] SRS resource reference signal
[0037] The source reference signal of the SRS resource.
[0038] Optionally, SRS includes any of the following uses:
[0039] SRS for antenna switching
[0040] SRS for codebook-based UL transmission
[0041] SRS for non-codebook based UL transmission and SRS for beam management.
[0042] That is, SRS can be used for any of the following: antenna switching, codebook-based uplink transmission, non-codebook-based uplink transmission, or beam management.
[0043] Optionally, the SRS power control parameter information includes at least one of the following: a path loss reference signal (PL-RS or PLRS) and a power control parameter set (setting).
[0044] The power control parameter group can include a set of power control parameters other than PLRS.
[0045] For example, a power control parameter group may include at least one of the following:
[0046] Target received power P0,
[0047] Road loss compensation factor (α or alpha)
[0048] Closed-loop power control index or closed-loop index (CLI), power control adjustment state value.
[0049] Here, the target received power P0 is the expected power reaching the base station; the path loss compensation factor α determines whether path loss is fully or partially compensated during power calculation; the closed-loop power control index (also known as the closed-loop power control process) indicates the closed-loop power control adjustment state that the SRS can maintain, and its value determines the process identifier of the closed-loop power control; the power control adjustment state value is divided into cumulative mode and absolute assignment mode. The closed-loop power control adjustment state index indicates the closed-loop power control adjustment state that the SRS can maintain.
[0050] For the unified transport configuration indication framework, a target-oriented approach can be used to determine the SRS configuration information. This target-oriented approach includes at least one of the following:
[0051] A. Use the common configuration information indicated by the network device, which can also be used for PUCCH and / or PUSCH;
[0052] B. Use first configuration information that differs from the public configuration information;
[0053] C. SRS configuration information in the SRS resource set indicated by the first MAC CE;
[0054] D. SRS configuration information indicated by the first MAC CE;
[0055] E. Configuration information determined using relevant methods, such as configuration information determined using relevant protocols prior to R17 (e.g., R15 and / or R16).
[0056] It should be noted that methods A to E described above are illustrative and do not limit the embodiments of this application. It is understood that any other possible methods can be used to determine the SRS configuration information. For example, other methods among the three optional implementations provided in the following embodiments can be used, which will not be elaborated here.
[0057] When the SRS configuration information includes SRS beam information, SRS PLRS, and SRS power control parameter group, three optional implementation methods will be provided below for illustrative purposes.
[0058] Option 1
[0059] When the SRS configuration information includes the SRS beam information, the SRS beam information can be determined based on any of the following:
[0060] A1. Use the common beam information indicated by the network device, which is also used for PUCCH and / or PUSCH.
[0061] Specifically, the network configuration or protocol stipulates that the SRS uses the same uplink beam information as the PUCCH and / or PUSCH. This uplink beam information can be selected by the network device from the TCI state pool, such as the ULTCI state or joint TCI state indicated from the TCI state pool via MAC CE or DCI.
[0062] B1. Use a first beam information that is different from the common beam information, which is selected by the network device from the TCI state pool along with the common beam information.
[0063] Specifically, the network configuration or protocol stipulates that the SRS uses first beam information that is different from the beam information of PUCCH and / or PUSCH. This first beam information, the beam information of PUCCH and / or PUSCH, is selected by the network device from the TCI state pool.
[0064] C1. Use the beam information of the SRS in the SRS resource set indicated by the first MAC CE.
[0065] Specifically, the first MAC CE includes: beam information (TCI state or spatial relation) for each SRS resource in the SRS resource set.
[0066] D1. Beam information of the SRS indicated by the first MAC CE.
[0067] Specifically, the first MAC CE includes: at least one SRS resource resource index and its corresponding beam information (such as TCI state or spatial relation).
[0068] E1. Spatial relationship information indicated by RRC or second MAC CE.
[0069] Specifically, network devices can use relevant protocols prior to R17 (such as R15 and / or R16) to indicate the beam information of SRS. For example, when the SRS type is periodic SRS, the network device configures the spatial relationship information of the SRS resource via RRC signaling; when the SRS type is semi-persistent SRS or aperiodic SRS, the network device configures the spatial relationship information of the SRS resource via RRC signaling and updates the spatial relationship information of the SRS resource using the MAC CE command.
[0070] In this embodiment of the application, since multiple methods for determining the beam information of the SRS are provided, after the terminal device determines the beam information of the SRS, the network device and the terminal device can have a consistent understanding of the SRS beam and establish a beam link based on the beam information, thereby realizing the transmission of the channel or reference signal and ensuring beam alignment.
[0071] The second optional implementation method
[0072] When the SRS configuration information includes the SRS power control parameter information, and the SRS power control parameter information includes the SRS PLRS, the SRS PLRS can be determined based on any of the following:
[0073] A2. Use a first PLRS, which is configured in or associated with common beam information indicated by the network device, and the first PLRS is also used for PUCCH and / or PUSCH.
[0074] Specifically, the network configuration or protocol specifies that the SRS uses the same first PLRS as the PUCCH and / or PUSCH. This first PLRS is configured in or associated with the common beam information indicated by the network device. This common beam information is selected by the network device from the TCI state pool. For example, the SRS uses the same beam information as the PUCCH and / or PUSCH, and also uses the same PLRS as the PUCCH and / or PUSCH, which is included in or associated with the common beam information.
[0075] B2. Use a second PLRS, which is configured in or associated with the common beam information, and which is different from the first PLRS.
[0076] Specifically, the network configuration or protocol stipulates that the SRS uses a second PLRS different from the first PLRS of the PUCCH and / or PUSCH. The first and second PLRS are configured in or associated with common beam information. This common beam information is selected by the network device from the TCI state pool. For example, the SRS can use the same beam information as the PUCCH and / or PUSCH, but this common beam information contains or is associated with multiple PLRSs, where the first PLRS is used for the PUCCH and / or PUSCH, and the second PLRS is used for the SRS.
[0077] C2. Use a third PLRS configured in or associated with the first beam information, which is different from the common beam information, and the first beam information and the common beam information are selected by the network device from the TCIstate pool.
[0078] Specifically, the network configuration or protocol stipulates that the SRS uses a third PLRS configured in or associated with the first beam information. This first beam information is different from the common beam information, and both the first beam information and the common beam information are selected by the network device from the TCI state pool.
[0079] D2, PLRS of SRS in the SRS resource set indicated by the first MAC CE.
[0080] Specifically, the first MAC CE includes: the PLRS corresponding to the SRS resource set, or the PLRS corresponding to the SRS resource in the SRS resource set.
[0081] E2, PLRS using the SRS indicated by the first MAC CE.
[0082] Specifically, the first MAC CE includes: a resource index of at least one SRS resource, and a PLRS corresponding to the at least one SRS resource.
[0083] F2. Use PLRS configured by RRC, or use PLRS configured by RRC and updated by MAC CE.
[0084] Specifically, network devices can use relevant protocols prior to R17 (such as R15 and / or R16) to indicate the PLRS of the SRS. For example, using the PLRS configured by RRC, or using the PLRS configured by RRC and updated by MAC CE.
[0085] G2. The PLRS is determined based on whether or not common beam information is used, which is also used for PUCCH and / or PUSCH.
[0086] It should be noted that the above "PLRS determined based on whether or not common beam information is used" refers to the PLRS determined using any one of A2 to F2 above.
[0087] For example, the network configuration or protocol stipulates that the PLRS of the SRS is determined based on whether or not common beam information is used: if the SRS uses common beam information, then Examples 1 to 3 of the following embodiments are used to determine the PLRS; if the SRS does not use common beam information, then Examples 4 to 6 of the following embodiments are used to determine the PLRS.
[0088] In this embodiment of the application, since multiple methods for determining the PLRS of the SRS are provided, the network device and the terminal device have a consistent understanding of the PLRS group, thereby ensuring correct data transmission and thus ensuring the accuracy of power control.
[0089] The third optional implementation method
[0090] When the SRS configuration information includes SRS power control parameter information, and the SRS power control parameter information includes SRS power control parameter groups, the SRS power control parameter groups can be determined based on any of the following:
[0091] A3. Use a first power control parameter group, which is configured in or associated with the common beam information indicated by the network device, and is also used for PUCCH and / or PUSCH.
[0092] Specifically, the network configuration or protocol specifies that the SRS uses the same first power control parameter group as the PUCCH and / or PUSCH. This power control parameter group is configured in or associated with the common beam information indicated by the network device. This common beam information is selected by the network device from the TCI state pool. For example, the SRS uses the same beam information as the PUCCH and / or PUSCH, and also uses the same power control parameter group as the PUCCH and / or PUSCH, which is included in or associated with the common beam information.
[0093] B3. Use a second power control parameter group, which is configured in or associated with the common beam information, and is different from the first power control parameter group.
[0094] Specifically, the network configuration or protocol specifies that the SRS uses a second power control parameter group that is different from the first power control parameter group of the PUCCH and / or PUSCH. This first and second power control parameter groups are configured in or associated with common beam information. This common beam information is selected by the network device from the TCIstate pool. For example, the SRS can use the same beam information as the PUCCH and / or PUSCH, but this common beam information contains or is associated with multiple power control parameter groups, where the first power control parameter group is used for the PUCCH and / or PUSCH, and the second power control group is used for the SRS.
[0095] C3. Use a third power control parameter group, which is configured in or associated with the first beam information, which is different from the common beam information, and the first beam information and the common beam information are selected by the network device from the TCI state pool.
[0096] Specifically, the network configuration or protocol specifies that the SRS uses a third power control parameter group configured in or associated with the first beam information. This first beam information is different from the common beam information, and both the first beam information and the common beam information are selected by the network device from the TCI state pool.
[0097] D3. Use the SRS power control parameter group in the SRS resource set indicated by the first MAC CE.
[0098] Specifically, the first MAC CE includes: the power control parameter group corresponding to the SRS resource set, or the power control parameter group corresponding to the SRS resource in the SRS resource set.
[0099] E3, Use the SRS power control parameter group indicated by the first MAC CE.
[0100] Specifically, the first MAC CE includes: a resource index of at least one SRS resource, and a power control parameter group corresponding to the at least one SRS resource.
[0101] F3, Power control parameter group configured using RRC.
[0102] Specifically, network devices can use protocols prior to R17 (such as R15 / R16) to indicate the power control parameter set of the SRS. For example, power control parameters such as target received power P0 and path loss compensation factor α in the power control parameter set configured by RRC.
[0103] G3. A power control parameter group determined based on whether or not common beam information is used, which is also used for PUCCH and / or PUSCH.
[0104] It should be noted that the "power control parameter group determined based on whether common beam information is used" mentioned above refers to the power control parameter group determined using any one of A3 to F3 mentioned above.
[0105] For example, the network configuration or protocol stipulates that the power control parameter group of the SRS is determined based on whether common beam information is used: if the SRS uses common beam information, the power control parameter group is determined using Examples 1 to 3 of the following embodiments; if the SRS does not use common beam information, the power control parameter group is determined using Examples 4 to 6 of the following embodiments.
[0106] In this embodiment of the application, since multiple methods for determining the power control parameter group of SRS are provided, the network device and the terminal device have a consistent understanding of the power control parameter group of SRS, thereby ensuring correct data transmission and thus ensuring the accuracy of power control.
[0107] Furthermore, regarding the PUCCH in the above three optional implementation methods, the PUCCH can be all PUCCH or part of PUCCH, that is, PUCCH refers to all or part of the PUCCH resources.
[0108] Furthermore, for the PUSCH in the above three optional implementation methods, the PUSCH is either a PUSCH based on dynamic grant or a PUSCH based on configured grant.
[0109] Furthermore, regarding the common beam information in the above three optional implementation methods, the common beam information is uplink beam information, which is the ULTCI state or joint TCI state indicated by MAC CE or DCI.
[0110] Furthermore, regarding the first MAC CE in the above three optional implementations, the first MAC CE can be used to indicate at least one of the following:
[0111] Identification information for SRS resource sets;
[0112] Beam information of the SRS resource set;
[0113] PLRS of SRS resource set;
[0114] SRS resource set power control parameter group;
[0115] Index information for at least one SRS resource;
[0116] Beam information of at least one SRS resource;
[0117] PLRS of at least one SRS resource;
[0118] At least one SRS resource power control parameter group;
[0119] Types of SRS;
[0120] Reference signal type.
[0121] Specifically, the beam information, PLRS, and power control parameter set of the aforementioned SRS resource set are used for all SRS resources in that SRS resource set. For example, all SRS resources in that SRS resource set use the beam information, PLRS, and power control parameter set of that SRS resource set.
[0122] For example, the first MAC CE can introduce a new indication function for CSI-RS, such as indicating the beam information of CSI-RS (in related technologies, only the beam information of semi-continuous CSI-RS can be indicated by MAC CE; the beams of periodic or aperiodic CSI-RS are configured using RRC). Therefore, the MAC CE for SRS and the MAC CE for CSI-RS can be the same. In this case, the first MAC CE needs to specify whether the RS type is CSI-RS or SRS; that is, the first MAC CE is used to indicate the reference signal type.
[0123] To illustrate this application more clearly, the embodiments of this application also provide the following seven examples to exemplarily explain the parameter determination method provided in this application.
[0124] Example 1
[0125] i. Determine the beam information of the SRS
[0126] The network device uses common beam information, which is also used for PUCCH and / or PUSCH. For example, the network configuration or protocol specifies that SRS uses the same uplink beam information as PUCCH and / or PUSCH.
[0127] Here, PUCCH refers to all or part of the PUCCH resources.
[0128] PUSCH refers to PUSCH based on dynamic grants or PUSCH based on configured grants.
[0129] Uplink beam information refers to the ULTCI state or joint TCI state indicated by the network device using MAC CE or DCI.
[0130] ii. Determine the PLRS of the SRS
[0131] A first PLRS is used, which is configured in or associated with common beam information indicated by the network device, and this first PLRS is also used for PUCCH and / or PUSCH. Exemplarily, the network configuration or protocol stipulates that the SRS uses the same PLRS as the PUCCH and / or PUSCH.
[0132] iii. Determine the SRS setting information
[0133] A first power control parameter group is used, which is configured in or associated with the common beam information indicated by the network device, and is also used for PUCCH and / or PUSCH. For example, network configurations or protocols may use a setting configured in or associated with the beam information, which is also used for PUCCH and / or PUSCH.
[0134] Furthermore, the CLI in the settings can determine whether to apply to SRS based on the network configuration.
[0135] For example, the TCI state is associated with the power control parameter group. The TCI state ID is {P0,alpha,CLI} and is used for PUCCH and SRS, or for PUSCH and SRS, or for PUCCH and PUSCH and SRS.
[0136] Example 2
[0137] i. Determine the beam information of the SRS
[0138] The network device uses common beam information, which is also used for PUCCH and / or PUSCH. For example, the network configuration or protocol specifies that SRS uses the same uplink beam information as PUCCH and / or PUSCH.
[0139] ii. Determine the PLRS of the SRS
[0140] 1. A first PLRS is used, which is configured in or associated with common beam information indicated by the network device, and which is also used for PUCCH and / or PUSCH. For example, the network configuration or protocol may stipulate the use of the same PLRS as PUCCH and / or PUSCH.
[0141] 2. Alternatively, use PLRS configured by RRC, or use PLRS configured by RRC and updated by MAC CE. That is, the network device uses the PLRS that indicates the SRS using relevant protocols prior to R17 (such as R15 and / or R16).
[0142] iii. Determine the SRS setting information
[0143] A second power control parameter group is used, which is configured in or associated with the common beam information, and this second power control parameter group is different from the first power control parameter group. For example, network configurations or protocols may use settings configured in or associated with the beam information, which are different from the settings for PUCCH and PUSCH.
[0144] Furthermore, the CLI settings in SRS can be configured to be applied to SRS based on network settings.
[0145] For example:
[0146] The TCI state is related to the power control parameter set.
[0147] If the TCI state ID - PC setting ID is {P01, alpha1, CLI1, P02, alpha2, CLI2, P03, alpha3, CLI3}, then P01, alpha1, and CLI1 are used for PUCCH, P02, alpha2, and CLI2 are used for PUSCH, and P03, alpha3, and CLI3 are used for SRS.
[0148] or,
[0149] If TCI state ID 1 - PC setting ID 1 {P01, alpha1, CLI1}, then it is used for PUCCH.
[0150] If TCI state ID 2-PC setting ID 2{P02, alpha2, CLI2}, then it is used for PUSCH.
[0151] If TCI state ID 3 - PC setting ID 3 {P03, alpha3, CLI3}, then it is used for SRS.
[0152] It should be noted that although the TCI state IDs mentioned above are different, the corresponding beams are the same, that is, they use the same uplink common beam.
