Abstract

The present invention provides a downlink beam management method, base station and terminal. The method includes: receiving an access request sent by a target terminal through a first SSB beam; when the number of accessed terminals does not exceed a threshold The terminal allocates target CSI-RS resources, and sends the target CSI-RS to the target terminal through the first SSB beam; and sends downlink service information and control signaling to the target terminal through the first SSB beam. In the downlink beam management method, base station and terminal provided by the present invention, the SSB beam sent by the base station does not carry CSI-RS, the base station sends the target CSI-RS to the target terminal through the first SSB beam, and sends the downlink to the target terminal through the first SSB beam Service information and control signaling occupy less time-frequency resources when managing downlink beams, which can avoid interference to neighboring cells and improve the communication quality of 5G NR.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a downlink beam management method, a base station and a terminal. Background technique [0002] 5G NR can improve cell coverage distance through beamforming in high-band scenarios, realize multi-user space division, and improve spectrum utilization to meet the needs of more diverse scenarios. [0003] In the existing management of downlink beams in 5G NR, the base station can configure multiple SSBs (Synchronization Signal and PBCH block, synchronization information block). Each SSB is transmitted in a narrow beam, and the beam scanning direction of each SSB beam is different. The base station can cover the entire cell through SSB beam polling scan. Each SSB beam carries a CSI-RS (Channel state information Reference Signal, channel state information reference signal), before the base station sends the downlink service information and control signaling to t...
