US 11,910,218 B2 · Beam reporting method and communications apparatus

Abstract

A beam reporting method and a communications apparatus is provided. The method includes that a terminal device receives first information, where the first information is used to configure at least two reference signal resource groups; and sending, by the terminal device, reporting information, where the reporting information includes related information of at least two beams, the at least two beams are used to send reference signals carried on at least two reference signal resources, and the reference signals sent by using the at least two beams can be simultaneously received by the terminal device, where the at least two reference signal resources are respectively from the at least two reference signal resource groups. In this application, related information of beams of at least two transmission points is reported through one time of beam scanning, to implement beam training in a CoMP system.
