Problems solved by technology

[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 is 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 utilization rate of the UL subframe is lower than that of the DL subframe, and the UL resources will be redundant.

Embodiment Construction

[0049]In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0050] The present invention takes a heterogeneous scenario as an example. The application of the homogeneous scenario is similar to the application of the heterogeneous scenario. The heterogeneous scenario refers to a heterogeneous scenario in which low-power nodes are deployed in the coverage area of ​​the macro base station to form different node types with the same coverage. system. Low Power Node (LowPowerNode, LPN) includes micro cell...

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...
