Title:
SIGNAL RECEIVING METHOD, TRANSMITTING METHOD, AND CORRESPONDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/218714
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are a signal receiving method, a transmitting method, and a corresponding device, for use in increasing the downlink signal receiving performance of a terminal device while switching antenna ports and/or beams. The method comprises: a terminal device receives indication information from a network device, the indication information being used for indicating at least one SRS resource, and the at least one SRS resource corresponding to a receiving antenna used by the terminal device for receiving a downlink signal; and the terminal device uses the receiving antenna corresponding to the at least one SRS resource to receive a downlink signal from the network device. With the network device indicating the receiving antenna to the terminal device, avoided is the problem in which the terminal device, when selecting a receiving antenna, is incapable of receiving the downlink signal as a result of switching receiving antenna ports and the degradation of receiving performance after switching, thus increasing downlink signal receiving performance.
