Embodiment Construction

[0039] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0040] It should be noted that the embodiment of the present invention only uses cooperative cell A and local cell B as examples to illustrate the technical solution of the present invention, and the embodiment of the present invention can also be applied to scenarios with more than two cooperative cells, for example, there are multiple In the scenario of coordinated cell A. The cooperating cell A mentioned herein is an adjacent or co-covered cell of the local cell B.

[0041] Some technical terms involved in the present invention are briefly introduced below:

[0042] The user equipment transmits SRS: Except for the special subframe of the TDD (TimeDivisionDuplexing, Time Division Duplexing) system, the SRS sequence is transmitted in...

Abstract

The invention discloses a cell coordination method and a base station, which belong to the field of communication technology. The method includes: receiving a sounding reference signal SRS configuration requirement of a coordinated cell; and configuring a second SRS parameter for the local cell according to the SRS configuration requirement of the coordinated cell. A base station is also disclosed, which base station includes: an acquisition module and a first configuration module.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a cell coordination method and a base station. Background technique [0002] In an LTE (Long-Term Evolution, long-term evolution) system, in order to implement uplink frequency domain scheduling, a UE (User Equipment, user equipment) needs to send an SRS sequence (Sounding Reference Signal, sounding reference signal) to sound a channel. Since multiple user equipments need to send SRS sequences, in LTE, a CDM (Code Division Multiplexing, code division multiplexing) mode and an FDM (Frequency Division Multiplexing, frequency division multiplexing) mode are used to multiplex the SRS sequences of multiple user equipments. [0003] In an actual networking scenario, there may be mutual interference between adjacent cells. Especially in heterogeneous networks, low-power nodes, namely micro base stations, are deployed in the coverage area of ​​macro base stations. The transmission...
