Document Type and Number:
WIPO Patent Application WO/2022/161036
Kind Code:
A1
Abstract:
The present application is applicable to the field of terminals, and provides a method and apparatus for selecting an antenna, an electronic device, and a readable storage medium. The method comprises: by means of each antenna, sending to a network device an antenna switching channel sounding reference signal; receiving an antenna selection message sent from the network device, the antenna selection message being used to indicate a first antenna among a plurality of antennas and the signal quality gain of each remaining antenna relative to the first antenna; obtaining the signal quality correction gain preset by the first antenna; and when the signal quality gain of each remaining antenna is greater than the signal quality correction gain of the first antenna, determining to use the first antenna for communication. Since the first antenna is the optimal antenna obtained through measurement by the network device, it is determined, according to the signal quality correction gain of the optimal antenna and the signal quality gain of each remaining antenna relative to the optimal antenna, whether to use the optimal antenna obtained by measurement by the network device for communication. Thus, an antenna having good communication quality can be selected more accurately and used for communication.
