Problems solved by technology

[0005] The UE needs to measure a large number of reference signals used to indicate the quality of narrow beams, and each narrow beam needs to be configured with RACH resources associated with it. This implementation method will bring excessive overhead and long measurement time to the UE. delay and lower RACH resource utilization

Abstract

The present invention provides a method, device, base station and user equipment for realizing beam optimization. On the base station side, the method includes: receiving a specific preamble sent by the UE on a specific random access channel resource; The best associated synchronization signal block, determining the best beam quality reference signal associated with the specific preamble according to the association relationship between the beam quality reference signal and the preamble resource; according to the relationship between the wide beam and the synchronization signal block The association relationship determines the best wide beam associated with the best synchronization signal block, and determines the best narrow beam associated with the best beam quality reference signal according to the association relationship between the narrow beam and the beam quality reference signal; Sending a random access response message to the UE on the best narrow beam.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, device, base station and user equipment for realizing beam optimization. Background technique [0002] In a communication system employing beam scanning, the base station can perform downlink beam optimization during the random access process of the UE, so that the UE can obtain better beamforming gain. [0003] Currently, the base station can trigger beam optimization before sending a random access response message to a UE (User Equipment, user equipment). Specifically, the base station may use a reference signal such as CSI-RS (Channel State Information Reference Signals, Channel State Information Reference Signals) to indicate the narrow beam quality, and the CSI-RS indicating the narrow beam quality is directly connected to the RACH (Random Access Channel, random access Channel) resources are associated. When the UE needs to report to the ba...
