Abstract

The embodiment of the invention provides an antenna switching device and a mobile terminal. The antenna switching device comprises an antenna switching module and a controller, wherein at least three antennae are respectively in corresponding connection with a transmitting and master receiving channel and at least two slave receiving channels through the antenna switching module; and the controller is respectively connected with a radio frequency transceiver circuit and the antenna switching module, when the mobile terminal is in a non-sleep mode, the controller determines the antenna with the highest received signal strength in the at least three antennae which are connected with the antenna switching module every preset time and controls the antenna switching module to switch the transmitting and master receiving channel to connect with the antenna with the highest received signal strength. According to the antenna switching device and the mobile terminal provided by the embodiment of the invention, each downlink antenna can be guaranteed to receive signals simultaneously, and the antenna with the highest received signal strength in the at least three antennae can also be randomly selected to transmit uplink signals, the defects of the prior art can be solved, and the communication quality of the mobile terminal can be greatly improved.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to an antenna switching device and a mobile terminal. Background technique [0002] The wireless communication of mobile terminals is developing in the direction of MIMO (Multiple-Input Multiple-Output). Some mobile terminals can support multiple downlink antennas to receive signals at the same time. Due to reasons such as power consumption, the current uplink transmission signal of the mobile terminal is generally transmitted by a single antenna. [0003] Since the antenna of the mobile terminal is easily affected by hand holding and human head, in the prior art, the mobile terminal adopts the dual-antenna switching technology when transmitting signals uplink, that is, the antenna with a better environment (such as not being held by the hand) is selected between the two antennas. An antenna to transmit the signal. [0004] The dual-antenna switching technology in...
