detailed description

Beam management is a key technology in 5G systems. How the base station can assist the terminal to complete the uplink beam scanning quickly and accurately through efficient and reasonable parameter configuration is also an important method in the uplink beam management.

In the 5G wireless communication system, after the terminal completes the access, the base station and terminal in the uplink direction can perform beam scanning, beam detection and beam indication through SRS to complete the entire process of uplink beam management. Wherein, the base station may allocate M groups of SRS resource sets (SRS Resource Sets) dedicated to beam management to the terminal through RRC signaling, and a group of SRS Resource Sets may include N SRS Resources. Here, M and N are related to the terminal capability parameter uplinkBeamManagement. In the SRS Resource used for beam management, the SRS transmission beam can be indicated by configuring the referenceSignal parameter of SRS-SpatialRelationInfo.

The existing specification points out that after associating the referenceSignal of the SRS-SpatialRelationInfo with the SSB, the terminal can realize the uplink non-codebook transmission of the SRS Resource, and its transmit beam originates from the downlink measurement of the SSB-Index pointed to by the referenceSignal of the SRS Resource. Or, after associating the referenceSignal of the SRS-SpatialRelationInfo with the channel state information reference signal (Channel State Information-Reference Signal, CSI-RS), the terminal can realize the uplink non-codebook transmission of the SRS Resource, and its transmit beam originates from the SRS Downlink measurement of the non-zero power CSI-RS resource identifier (NZP-CSI-RS-ResourceId) pointed to by the referenceSignal of Resource.

The same transmit beam or different transmit beams can be used between each SRS Resource used for beam management, that is, it depends on whether the downlink reference signals associated with each SRS Resource are the same.

On the one hand, the base station needs to reasonably associate the SSB with the SRS resource used for beam management to ensure the validity and efficiency of the transmitted beam when the terminal scans the uplink beam, shorten the time of the uplink beam scan, 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 problem to be solved by the base station.

The existing implementation is that the base station associates the SSB beams one by one by configuring multiple SRS resources. On the one hand, this solution is limited by the terminal capability (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, they cannot be associated one by one. On the other hand, ineffective or inefficient beam scanning will increase the time of the beam training process and waste cell SRS resources, thereby affecting cell user capacity.

In order to make the purposes, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments These are only some of the embodiments of the present disclosure, but not all of the embodiments.

The measurement report contains signal strength values for the k associated beams. The associated beam is the target beam used for association with the SRS resource. k is an integer greater than 1.

The value of k may depend on the uplink beam management capability of the terminal, and the uplink beam management capability is positively correlated with the value of k.

The target beam may be an SSB beam, a CSI-RS beam, or other beams used for association with SRS resources, and may indicate an uplink SRS transmission beam, which is not exemplified here.

Step 102: Send the SRS spatial relationship information to the terminal, so that the terminal can determine the uplink SRS transmit beam according to the SRS spatial relationship information.

Specifically, after determining the SRS-SpatialRelationInfo, the base station sends the SRS-SpatialRelationInfo to the terminal, so that the terminal can determine the transmission beam of the uplink SRS according to the SRS-SpatialRelationInfo.

For example, the base station may send the SRS-SpatialRelationInfo to the terminal through RRC signaling.

Then, i associated beams to be associated are determined according to the first threshold value and the second threshold value. The associated beam to be associated is the associated beam corresponding to the signal strength value 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.
