Abstract

The invention discloses a beam selection method and related equipment, used for solving the technical problem that in the prior art, the reliability of data transmission is low. The method comprises the steps as follows: a terminal receives training signals sent by N downlink sending beams of a base station and beam grouping information of the N downlink sending beams sent by the base station, wherein N is an integer more than 0; and the terminal determines T downlink sending beams from the N downlink sending beams based on the training signals and the beam grouping information, wherein T is apositive integer less than N.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a beam selection method and related equipment. Background technique [0002] Beamforming is a signal preprocessing technology based on antenna arrays. Beamforming generates directional beams by adjusting the weighting coefficients of each array element in the antenna array, so that significant array gain can be obtained. Therefore, beamforming technology has great advantages in terms of extended coverage, improved edge throughput, and interference immunity. [0003] Currently, beamforming is mainly performed on both the base station side and the terminal side. For the downlink direction, the base station sends a downlink beam training signal, the terminal measures the downlink beam training signal, selects the best base station transmission beam, and feeds beam-related information back to the base station, and at the same time selects the corresponding best recept...
