Problems solved by technology

When the working frequencies and time slots of some users in other adjacent cells are the same as those of users in this cell, it will cause co-frequency interference to those same service time slots of users in this cell, affecting the solution of downlink reception. tuning performance
The consequence of this is that it may affect the call quality or data throughput rate, and sometimes affect the maintenance of the wireless link and eventually lead to dropped calls, thereby affecting network capacity

Abstract

Embodiments of the invention provide a method and an apparatus for canceling co-channel interference. The method comprises the steps of selecting candidate co-channel interference cells from a plurality of potential co-channel interference cells according to business measurement implemented in time slot for carrying out downlink receiver; and determining a target candidate co-channel interference cell from the candidate co-channel interference cells based on measurement results directed to the candidate co-channel interference cells, so as to eliminate the co-channel interference from the target co-channel interference cell. The embodiments of the invention can rapidly and accurately determine the co-channel interference cells and efficiently realize elimination of the co-channel interference.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 61 / 647,151, filed May 15, 2012, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] Embodiments of the present invention relate to the communication field, and in particular, to a method and device for eliminating co-channel interference. Background technique [0004] Time Division Synchronous Code Division Multiple Access (TD-SCDMA) technology, as a widely used mobile communication system, has established commercial networks in many areas and is expanding to more areas. [0005] However, co-channel interference has always been one of the main problems plaguing the quality of TD-SCDMA network. Specifically, since the current TD-SCDMA network supports N frequency points, the working frequency of the dedicated channel may be the main frequency or the auxiliary frequency, so different cells may have the s...
