Problems solved by technology

Among them, in order to make the handover more accurate, the length of the traditional measurement time window is generally relatively long, so that some communication channels will attenuate quickly, especially for the scene where the uplink transmission is limited, the mobile phone may be affected by the traditional measurement If the time window is too long, it is impossible to switch to a better antenna in time, resulting in call drop

Abstract

An antenna switching method and device for improving communication quality. The antenna switching method includes: transmitting data through a first antenna; measuring the signal quality of the first antenna and the signal quality of the second antenna; determining that the signal quality of the second antenna is better than the signal quality of the first antenna, and The number of retransmissions for sending the data is greater than or equal to a preset threshold N, where N is a positive integer; switching from the first antenna to the second antenna to transmit the data through the second antenna.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to an antenna switching method and device. Background technique [0002] There may be multiple antennas installed in the current mobile phone, and the multiple antennas can work independently, that is, all of them can transmit and receive signals, so that the mobile phone can work better, and the mobile phone generally uses one of the antennas at a time. It involves the selection of one of the antennas for the mobile phone to use. At present, the mobile phone selects an antenna with better performance for use by measuring the performance of the antenna. [0003] Specifically, the antenna switching of the mobile phone is evaluated and compared in the traditional measurement time window. Taking two antennas in the mobile phone as an example, the mobile phone performs multiple rounds of measurements on the performance of the two antennas in the traditional measure...
