Method and device for processing interference

Abstract

The invention discloses a method for processing interference. The method comprises the following steps that: a user equipment (UE) receives uplink control channel configuration information of a cell in a neighboring base station, which is transmitted by a service base station, wherein the uplink control channel configuration information comprises physical uplink control channel (PUCCH) configuration information, physical random access channel (PRACH) configuration information or channel detection reference symbol Sounding (RS) configuration information of the cell in the neighboring base station; and the UE determines the position of the service base station, which is interfered by the neighboring base station, according to the configuration information, and eliminates the interference according to the determined position of the interference. The invention discloses a device for eliminating the interference.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to an interference processing method and device. Background technique [0002] In a frequency division duplex (FDD, Frequency Division Duplexing) system, on the one hand, the downlink (DL, Down link) frequency band and the uplink (UL, Uplink) frequency band usually use the same bandwidth, and the traffic volume of the DL frequency band is usually higher than that of the UL frequency band. The amount of traffic in the UL frequency band is relatively large, resulting in the relative idleness of some UL resources in the UL frequency band. On the other hand, when the UL traffic volume matches the DL traffic volume, since the UL spectrum efficiency is higher than the DL spectrum efficiency, the usage rate of the UL subframe is lower than that of the DL subframe, and UL resources will be redundant. In order to effectively utilize UL redundant resources, part of the U...
