Embodiment Construction

[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0017] Aiming at the dual-pass chip solution, a processing method and mobile terminal for reducing co-channel interference are designed. Take China Telecom as an example: the existing dual-pass chip solution requires the layout of three antennas in the RF front end: LTE main antenna, LTE diversity antenna and CDMA antenna. And the LTE main antenn...

Abstract

The embodiment of the invention provides a processing method for reducing co-frequency interference and a mobile terminal. The method is used for the mobile terminal comprising a two-way chip. The radio frequency front end of the mobile terminal is provided with three antennas. The method comprises a first network main antenna, a first network diversity antenna and a second network diversity antenna, and comprises the following steps: detecting the use state of the mobile terminal, and closing the first network diversity antenna if detecting that the mobile terminal performs a voice call through the second network antenna. The mobile terminal executes the method. According to the processing method for reducing the co-frequency interference and the mobile terminal provided by the embodimentof the invention, the co-frequency interference of signals between mobile terminal antennas with bi-pass chips is effectively reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of mobile communications, and in particular to a processing method for reducing co-channel interference and a mobile terminal. Background technique [0002] Currently, mobile phones support multiple standards, including CDMA, GSM, WCDMA, TDSCDMA, TDD-LTE and LTE FDD. 2G and 3G low-band excellent resources to lay out the existing main business and redeploy LTE. Considering the operation of the existing 2G and 3G services, direct hard handover to 4G is impractical. Deploying 2G, 3G, and 4G requires terminals to support each system at the same time in the same low frequency band. [0003] Taking China Telecom's existing low-band frequency as an example, both CDMA 1x and Evdo are deployed in the range of 825-835MHz. In order to avoid co-channel interference, 1x and evdo are generally deployed on both sides of the frequency band, and part of the bandwidth is taken out within the range of 10...
