Abstract

Embodiments of the present invention provide a cell node, an uplink interference processing system and method. The micro cell node of the present invention includes: a receiving module (11), configured to receive the interference cancellation request sent by the macro cell node, the interference cancellation request at least includes uplink configuration information of user equipment (UE), and the uplink configuration information of UE includes uplink pressure Module configuration information or the gain factor used to calculate the auxiliary dedicated physical control channel (S-DPCCH); the receiving module (11) is also used to receive the configuration notification message sent by the macro cell node, and the configuration notification message is used to indicate the uplink configuration of the UE Mode: the interference processing module (12), configured to perform interference cancellation according to the interference cancellation request received by the receiving module (11) and the configuration notification message of the notification module. The embodiment of the present invention solves the problem of low practicability caused by only considering the conventional scenario of UE uplink configuration in the existing technology for eliminating interference signals in a heterogeneous network (Hetnet), and improves the application of the embodiment of the present invention scope.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a cell node, an uplink interference processing system and method. Background technique [0002] The wireless communication field is facing the pressure of explosive growth of data services. In order to increase network capacity and reduce transmission costs, a heterogeneous network (Heterogeneous Network, Hetnet for short) technology has been proposed in the industry. The Hetnet is composed of multiple cells of different sizes and types, which may include, for example, a macro cell (Macro Cell) and a micro cell. The micro cells include: a micro cell (Micro cell), a pico cell (Pico Cell), a femto cell (FemtoCell), a cell in the form of a remote radio head (Remote Radio Head, RRH for short), and the like. Through the deployment of macro cells and micro cells, the network capacity of traffic-intensive areas can be effectively improved, and because of the small scale of...
