Abstract

The invention provides mobile terminal equipment and a signal transceiving method thereof. The equipment includes a master control chip; a double-pole double-throw antenna switch which is connected with the main control chip; a first antenna, a second antenna, a master set path and a first diversity path, which are respectively connected with the double-pole double-throw antenna switch, wherein when the main control chip detects that the attenuation of a second antenna signal exceeds a set value, the main control chip controls the double-pole double-throw antenna switch to connect the master set path with the first antenna and the first diversity path with the second antenna at an uplink moment, and uplink signals are sent through the master set path; at a downlink moment, the main controlchip controls the double-pole double-throw antenna switch to connect the master set path with the second antenna and the first diversity path with the first antenna, and downlink signals are receivedthrough the master set path and the first diversity path. According to the invention, the problems of low receiving sensitivity and low experience degree under weak signal coverage when the existingmobile terminal receives and transmits signals are solved.

Description

technical field [0001] The invention relates to the field of mobile terminal communication, in particular to a mobile terminal device and a method for sending and receiving signals. Background technique [0002] In mobile communication, the sending and receiving of signals is realized through the antenna, and the mobile terminal transmits the signal through the antenna by connecting the path of the radio frequency front-end to the antenna, and returns the signal received through the antenna. The channels of the radio frequency front end include a main channel and a diversity channel. Usually, the channel of the radio frequency front end of the mobile terminal is connected to the antenna in the main collection channel and the lower antenna, and the diversity channel is connected to the upper antenna. However, in the normal state of holding the mobile terminal with one hand, the hand-holding effect will cause signal attenuation, and the lower antenna The signal of the antenna...
