Abstract

The present invention provides a mobile terminal device and a method for sending and receiving signals thereof. The device includes: a main control chip, a double-pole double-throw antenna switch connected to the main control chip, and a double-pole double-throw antenna switch connected to the double-pole double-throw antenna switch respectively. The first antenna, the second antenna, the main collection path and the first diversity path, wherein: when the main control chip detects that the attenuation of the second antenna signal exceeds the set value, it controls the double-pole double-throw antenna switch to be connected respectively at the uplink time The main collection path and the first antenna, and the first diversity path and the second antenna, and send the uplink signal through the main collection path, and at the time of downlink, control the double pole double throw antenna switch to connect the main collection path and the second antenna respectively, and The first diversity path is connected with the first antenna, and the downlink signal is received through the main path and the first diversity path. The mobile terminal equipment and the method for sending and receiving signals provided by the present invention solve the problems of low receiving sensitivity and low experience under weak signal coverage when the existing mobile terminal sends and receives signals.

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...
