Title:
BEAM TRAINING METHOD AND APPARATUS, AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/141205
Kind Code:
A1
Abstract:
The present application relates to the technical field of communications, and discloses a beam training method and apparatus and a communication device. When the beam training method is executed, a first communication device can obtain first vector information, and determines first information according to the first vector information and the association relationship between the first vector information and first information of a second cell, the first information being first reference signal resource information, or the first information being first transmission configuration indicator (TCI) state information; if the first information is the first reference signal resource information, a first reference signal is received on a first reference signal resource, or if the first information is the first TCI state information, a downlink physical channel is received according to the first TCI state information. Beam training is performed by means of the method, such that the interaction of signaling can be reduced, and the efficiency of beam training can be improved.
