Embodiment 1

[0086] Embodiment 1 describes that the Pico base station notifies the base station where the adjacent cell is located. The cell on the Pico base station is configured with ABS. This method changes the load information process. If the load information process is not changed, but only the resource status request is changed, then it needs to be as in Embodiment 2. way to solve the problem. If the Macro base station 2 does not know when the Pico base station configures the ABS subframe, the Macro base station 2 sends a resource status request to the Pico base station, requesting the Pico base station to report the ABS status, and the Pico base station will send a failed resource status response. The Macro base station 2 will think that the Pico base station does not have the capability of configuring the ABS subframe, so it will no longer send a message to the Pico base station, and ask the Pico base station to report the ABS status. Embodiment 2 is to solve this problem.

Abstract

The invention brings forward a method for eliminating interference among districts. The method comprises the following steps: a first base station sending a load information message to a second base station, wherein the load information message comprises indication information, and the indication information is used for indicating that a district under the first base station is already configured with an ABS subframe; the second base station sending a resource state request message to the first base station, wherein the resource state request message comprises report characteristics; the first base station sending a resource condition response message to the second base station; and the first base station sending a resource condition report message to the second base station, wherein the resource condition report message comprises a measuring result. According to the scheme brought forward by the invention, by configuring corresponding messages, the ABS configuration situations can be understood by base stations so that when measuring configuration is carried out, UE can be configured to measure district reference signals of a base station corresponding to an ABS subframe, the measuring accuracy is improved, and the problem of eliminating interference among districts can be effectively solved.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular, the present invention relates to a method and equipment for inter-cell interference elimination. Background technique [0002] Modern mobile communication tends to provide users with high-speed multimedia services, such as figure 1 Shown is the system architecture diagram of System Architecture Evolution (SAE). in: [0003] User Equipment (UE) 101 is a terminal device for receiving data. Evolved Universal Terrestrial Radio Access Network (E-UTRAN) 102 is a radio access network including macro base stations (eNodeBs / NodeBs) providing UEs with an interface to access the radio network. Mobility Management Entity (MME) 103 is responsible for managing UE's mobility context, session context and security information. Serving Gateway (SGW) 104 mainly provides user plane functions, and MME 103 and SGW 104 may be in the same physical entity. The packet data network gateway (P...
