Document Type and Number:
WIPO Patent Application WO/2023/151391
Kind Code:
A1
Abstract:
The present application relates to the technical field of wireless communications. Provided are a beam training method and a communication apparatus, which can reduce the interference of trained beams in different directions on an information receiving and transmitting process of other user equipments (UEs), thereby facilitating an improvement in the reliability of information transmission. The method comprises: a first UE transmitting first control information by means of a first transmitting beam, wherein the first control information comprises resource location information of a first resource; and then, the first UE transmitting a first reference signal on the first resource by means of M transmitting beams, wherein M is a positive integer, the first transmitting beam is different from each of the M transmitting beams, and the first transmitting beam covers each of the M transmitting beams.
