Abstract

The embodiment of the invention provides a method for correcting channels among base stations and a base station, and aims to realize channel correction of base stations in a large-area network, even in a whole network range. The method comprises the following steps that: a base station k+1 determines a channel difference parameter gammak+1 between the base station k+1 and a base station k according to a channel difference parameter gammak between the base station k and a base station k-1; and the base station k+1 performs channel correction relative to the base station k according to the channel difference parameter gammak+1, wherein k is a positive integer. According to the embodiment of the invention, the channel difference between one of two base stations on which channel correction is finished and a base station to be corrected is determined through the channel difference between the two base stations on which channel correction is finished, so that channel correction is performed on the base station to be corrected according to the channel difference, and channel correction in the large-area network, even in the whole network range can be realized.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, relates to a method for channel correction between base stations and a base station. Background technique [0002] Long Term Evolution (LTE), as the fourth-generation wireless cellular access method, adopts Orthogonal Frequency Division Multiplexing (OFDM) and Multi-input Multi-output (MIMO) And other technologies improve spectrum efficiency and system capacity. [0003] The Coordinated Multiple Points (CoMP) technology of the LTE system enables base stations in the system to increase the throughput of cell-edge users through coordinated transmission, thereby improving cell-edge coverage and user experience. A joint transmission (Joint Transmission, JT) technology is a manner of the CoMP technology, which performs joint beamforming transmission on antennas of a cooperative set. In the system, in order to obtain the gain of JT, it is necessary to perform joint channel cor...
