[0003] In related technologies, after the terminal completes access, the uplink base station and the terminal can complete the entire uplink beam management process through the Sounding Reference Signal (SRS). The base station can allocate several SRS resources for beam management to the terminal through Radio Resource Control (RRC) signaling. The SRS transmission beam can be indicated by configuring the reference signal parameter of the SRS spatial relation information (SRS Spatial RelationInfo). Existing specifications indicate that after the reference signal of the SRS-Spatial RelationInfo is associated with the Synchronization Signal and PBCH Block (SSB), the terminal can realize uplink non-codebook transmission of that SRS resource, and its transmission beam originates from the downlink measurement of the SSB index (ssb-index) pointed to by the reference signal of that SRS resource.

[0075] Beam management is a key technology in 5G systems. How base stations can efficiently and effectively configure parameters to assist terminals in quickly and accurately completing uplink beam scanning is an important method in uplink beam management.

[0076] In a 5G wireless communication system, after a terminal completes access, the uplink base station and the terminal can perform beam scanning, beam detection, and beam indication via SRS to complete the entire uplink beam management process. Specifically, the base station can allocate M dedicated SRS resource sets for beam management to the terminal via RRC signaling. Each SRS resource set can include N SRS resources. Here, M and N are related to the terminal capability parameter `uplinkBeamManagement`. The SRS transmission beam can be indicated by configuring the `referenceSignal` parameter of `SRS-SpatialRelationInfo` within the SRS resource used for beam management.

[0077] Current specifications indicate that by associating the SRS-SpatialRelationInfo's reference signal with the SSB, the terminal can achieve uplink non-codebook transmission of the SRS Resource, with its transmit beam originating from the downlink measurement of the SSB-Index pointed to by the SRS Resource's reference signal. Alternatively, by associating the SRS-SpatialRelationInfo's reference signal with the Channel State Information-Reference Signal (CSI-RS), the terminal can achieve uplink non-codebook transmission of the SRS Resource, with its transmit beam originating from the downlink measurement of the non-zero power CSI-RS resource identifier (NZP-CSI-RS-ResourceId) pointed to by the SRS Resource's reference signal.

[0078] The SRS Resources used for beam management can use the same transmit beam or different transmit beams, depending on whether the downlink reference signals associated with each SRS Resource are the same.

[0079] On the one hand, base stations need to reasonably associate SSBs with SRS Resources used for beam management to ensure the effectiveness and efficiency of transmitted beams during terminal uplink beam scanning, shorten uplink beam scanning time, and quickly complete the beam training process. On the other hand, the total SRS resources of a cell are limited, and avoiding invalid or inefficient resource allocation is also a technical challenge that base stations need to solve.

[0080] The existing implementation involves the base station configuring multiple SRS Resources and associating them one by one with the SSB beams. This approach is limited by terminal capabilities (measured by the terminal capability parameter `uplinkBeamManagement`). If the number of SRS Resources used for beam management is less than the number of SSB beams in the cell, one-to-one association is not possible. Furthermore, invalid or inefficient beam scanning increases the time required for beam training, wastes cell SRS resources, and consequently affects cell user capacity.

[0081] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0082] Based on the above-mentioned technical problems, this application provides an uplink beam indication / scanning method based on SSB / CSI-RS measurement and feedback, which aims to improve the efficiency of uplink beam scanning, save SRS resources of the cell, and increase the cell user capacity.

[0083] Figure 1 This is one of the schematic diagrams of a beam pointing method provided in an embodiment of this application, such as... Figure 1 As shown in the embodiments of this application, a beam indication method is provided, the executing entity of which can be a network device, such as a base station. The following description uses a base station as an example of a network device. The method includes:

[0084] Step 101: Determine the spatial relationship information of the detection reference signal (SRS) based on the measurement report sent by the terminal; the measurement report contains signal strength values ​​for k associated beams; the associated beams are target beams used to associate with SRS resources; k is an integer greater than 1.

[0085] Specifically, the base station determines the SRS-SpatialRelationInfo based on the measurement report sent by the terminal. This measurement report contains signal strength values ​​for k associated beams. The associated beams are the target beams used to associate with SRS resources. k is an integer greater than 1.

[0086] The value of k can depend on the uplink beam management capability of the terminal, and the uplink beam management capability is positively correlated with the value of k.

[0087] The target beam can be an SSB beam, a CSI-RS beam, or any other beam used to associate with SRS resources and to indicate the transmit beam of the uplink SRS. Examples will not be given here.

[0088] Step 102: Send the SRS spatial relationship information to the terminal so that the terminal can determine the uplink SRS transmission beam based on the SRS spatial relationship information.

[0089] Specifically, after the base station determines the SRS-SpatialRelationInfo, it sends the SRS-SpatialRelationInfo to the terminal so that the terminal can determine the uplink SRS transmission beam based on the SRS-SpatialRelationInfo.

[0090] For example, the base station can send SRS-SpatialRelationInfo to the terminal via RRC signaling.

[0091] After receiving the SRS-SpatialRelationInfo, the terminal parses out the SSB-Index or NZP-CSI-RS-ResourceId, and performs channel detection on each SSB to obtain the uplink SRS transmit beam information.

[0092] The beam indication method provided in this application determines the SRS spatial relationship information based on the measurement report sent by the terminal, and uses the prior information of downlink beam measurement to reasonably and efficiently configure the SRS resources used for uplink beam management, which shortens the uplink beam scanning time and saves cell SRS resources.

[0093] Based on any of the above embodiments, the target beam is either the Synchronization Signal Block (SSB) beam or the Channel State Information Reference Signal (CSI-RS) beam.

[0094] Specifically, in the embodiments of this application, the target beam is an SSB beam or a CSI-RS beam.

[0095] The beam indication method provided in this application determines SRS spatial relationship information based on the measurement report sent by the terminal. The measurement report includes signal strength values ​​for the SSB beam or CSI-RS beam, making the configuration more flexible, further shortening the uplink beam scanning time, and saving cell SRS resources.

[0096] Based on any of the above embodiments, determining the spatial relationship information of the detection reference signal (SRS) based on the measurement report sent by the terminal specifically includes:

[0097] Based on the measurement report, i beams to be associated are determined; i is an integer greater than 1;

[0098] The i beams to be associated are associated with SRS resources one by one to generate SRS spatial relationship information.

[0099] Specifically, in this embodiment of the application, the base station determines the SRS-SpatialRelationInfo based on the measurement report sent by the terminal using the following steps:

[0100] First, the base station determines i beams to be associated based on the measurement report; i is an integer greater than 1.

[0101] For example, i can be configured as a fixed value, and the base station can select the i associated beams with the largest signal strength values ​​from the k associated beams in the measurement report as the associated beams to be associated. Where i ≤ k.

[0102] i can be a non-fixed value. The base station can select the associated beams with signal strength values ​​greater than a preset threshold from the k associated beams in the measurement report as the i associated beams to be associated. Where i≤k.

[0103] Then, the base station associates each of the i beams to be associated with the SRS resource to generate SRS-SpatialRelationInfo.

[0104] That is, configure the value of the referenceSignal parameter in SRS-SpatialRelationInfo to the value of the index of the associated beam to be associated. For example, this index can be SSB-Index or NZP-CSI-RS-ResourceId.

[0105] The beam indication method provided in this application determines i SSBs to be associated based on the measurement report, further shortening the uplink beam scanning time and saving cell SRS resources.

[0106] Based on any of the above embodiments, determining i beams to be associated based on the measurement report specifically includes:

[0107] A first threshold value is determined based on the maximum value among the signal strength values ​​of the k associated beams in the measurement report; a second threshold value is determined based on the average value of the signal strength values ​​of the k associated beams in the measurement report.

[0108] Based on the first threshold value and the second threshold value, the i associated beams to be associated are determined; the associated beams to be associated are the associated beams corresponding to the signal strength values ​​in the measurement report that are greater than the target threshold value; the target threshold value is the maximum value between the first threshold value and the second threshold value.

[0109] Specifically, in this embodiment, the maximum and average signal strength values ​​of the associated beams in the measurement report are considered to determine the associated beams to be associated. The specific steps for determining i associated beams based on the measurement report are as follows:

[0110] First, the base station determines the first threshold value based on the maximum value of the signal strength values ​​of the k associated beams in the measurement report.

[0111] For example, the maximum value of the signal strength of the associated beam can be used directly as the first threshold value, or the first threshold value can be determined based on the maximum value of the signal strength of the associated beam and a preset weight value.

[0112] The second threshold value is determined based on the average signal strength values ​​of the k associated beams in the measurement report.

[0113] For example, the average signal strength value of the associated beam can be used directly as the second threshold value, or the second threshold value can be determined based on the average signal strength value of the associated beam and a preset weight value.

[0114] Then, according to the first threshold value and the second threshold value, i correlation beams to be associated are determined. The correlation beams to be associated are the correlation beams corresponding to the signal strength values greater than the target threshold value in the measurement report. The target threshold value is the maximum value between the first threshold value and the second threshold value.

[0115] The beam indication method provided by the embodiments of the present application determines the correlation beams to be associated by considering the maximum value and the average value of the signal strength values of the correlation beams in the measurement report, further shortening the time of the uplink beam scanning and saving the cell SRS resources.

[0116] Based on any of the above embodiments, the first threshold value is determined according to the maximum value of the signal strength values of the k correlation beams in the measurement report, which is expressed by the formula as follows:

[0117] Threshold1 = max(RSRPBuffer) * w1

[0118] Where, Threshold1 is the first threshold value, RSRPBuffer is an array composed of the signal strength values of the k correlation beams in the measurement report, and w1 is the first preset constant.

[0119] Specifically, in the embodiments of the present application, the first threshold value is determined according to the maximum value of the signal strength values of the correlation beams and the preset weight value.

[0120] The first threshold value is determined according to the maximum value of the signal strength values of the k correlation beams in the measurement report, which is expressed by the formula as follows:

[0121] Threshold1 = max(RSRPBuffer) * w1

[0122] Where, Threshold1 is the first threshold value, RSRPBuffer is an array composed of the signal strength values of the k correlation beams in the measurement report, and w1 is the first preset constant. The value of w1 is related to the carrier frequency, the channel environment, the number of SSB beams, etc., and can be configured according to experience. 0 < w1 ≤ 1. For example, it is configured to be 0.5.

[0123] The beam indication method provided by the embodiments of the present application determines the first threshold value according to the maximum value of the signal strength values of the correlation beams and the preset weight value, further shortening the time of the uplink beam scanning and saving the cell SRS resources.

[0124] Based on any of the above embodiments, the second threshold value is determined according to the average value of the signal strength values of the k correlation beams in the measurement report, which is expressed by the formula as follows:

[0125] Threshold2 = mean(RSRPBuffer) * w2

[0126] Among them, Threshold2 is the second threshold value, RSRPBuffer is an array composed of the signal strength values of k associated beams in the measurement report, and w2 is the second preset constant.

[0127] Specifically, in the embodiment of the present application, the second threshold value is determined according to the average value of the signal strength values of the associated beams and the preset weight value.

[0128] The second threshold value is determined according to the average value of the signal strength values of k associated beams in the measurement report, which is expressed by the formula as follows:

[0129] Threshold2 = mean(RSRPBuffer) * w2

[0130] Among them, Threshold2 is the second threshold value, RSRPBuffer is an array composed of the signal strength values of k associated beams in the measurement report, and w2 is the second preset constant. The value of w2 is related to the carrier frequency, channel environment, number of SSB beams, etc., and can be configured according to experience. 0 < w2 ≤ 1. For example, it is configured as 0.5.

[0131] The beam indication method provided by the embodiment of the present application determines the second threshold value according to the average value of the signal strength values of the associated beams and the preset weight value, further shortening the time of uplink beam scanning and saving the cell SRS resources.

[0132] Based on any of the above embodiments, before determining the sounding reference signal SRS spatial relationship information based on the measurement report sent by the terminal, it further includes:

[0133] Sending measurement configuration information to the terminal; for the terminal to measure the associated beams according to the measurement configuration information.

[0134] Specifically, in the embodiment of the present application, before the base station determines the SRS - SpatialRelationInfo based on the measurement report sent by the terminal, it needs to first send measurement configuration information to the terminal for the terminal to measure the associated beams according to the measurement configuration information. The specific steps are as follows:

[0135] The base station sends measurement configuration information to the terminal. The measurement configuration information includes the associated beams indicating the terminal to perform measurements. The measurement configuration information can be sent through RRC signaling. The associated beam is the target beam used to be associated with the SRS resource, and the target beam can be an SSB beam or a CSI - RS beam.

[0136] The terminal receives the measurement configuration information sent by the network device.

[0137] After receiving the measurement configuration information sent by the network device, the terminal determines the associated beam that the network device instructed it to perform the measurement.

[0138] The terminal measures the associated beam that the network device instructs it to measure and generates a measurement report.

[0139] Finally, the terminal sends the measurement report to the network device.

[0140] The beam indication method provided in this application reduces signaling overhead by instructing the terminal to perform targeted measurements through measurement configuration information.
