Abstract

The present invention provides an antenna selection method and a terminal, the method comprising: determining the system information and frequency band information of the terminal communication; determining the target antenna among the plurality of antennas, wherein, in the frequency band of the system, The target antenna is matched with the radio frequency transceiver of the terminal; and the target antenna is used to perform communication in the frequency band of the standard. In this way, the standard information and frequency band information of terminal communication can be determined, and then the antenna matching the radio frequency transceiver of the terminal within the standard and frequency band of terminal communication can be determined. The antenna can be used for communication in the frequency band of the above standard, and the matching degree between the antenna and the radio frequency transceiver is good.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to an antenna selection method and a terminal. Background technique [0002] With the development and progress of science and technology, terminals are becoming more and more popular, and the number of antennas on the terminal is also increasing. There may be two or more antennas on the terminal. [0003] In the prior art, the switching of the antennas in the terminal is determined by the operating frequency band of the terminal, and signal reception or signal transmission is completed on the same antenna. Due to the wide operating bandwidth of most standards, the problem of poor matching between the antenna and the RF transceiver may occur after switching the antenna. For example, after the antenna is switched, the signal reception may be normal but the signal transmission is poor; or the signal transmission may be normal but the signal reception is poor. [000...
