Method for detecting adjacent cell information

Abstract

The invention discloses a method for detecting adjacent cell information, which comprises that: in a current detection period of the detection, a base station selects a training sequence from the training sequences which are not allocated to a cell and not selected in the detection, and performs channel estimation according to the selected training sequence and a training sequence signal receivedon each sub-frame in the detection period to obtain a corresponding channel impact response estimation value of the selected training sequence respectively on each of the sub-frames in the detection period, wherein the cell is any cell covered by the base station; the operations are repeatedly executed until all training sequences not allocated to the cell are selected in the detection; the operations are repeatedly executed for preset detection times; and the base station utilizes the peak value of all the channel impact response estimation values to determine the training sequence to be allocated to the adjacent cell of the cell. The method for detecting the adjacent cell information can realize the automatic detection on the adjacent cell information.

Description

technical field [0001] The invention relates to a joint detection technology, in particular to a method for detecting adjacent cell information. Background technique [0002] Joint detection technology is a key technology in Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system. Compared with the traditional RAKE receiver, the use of joint detection can greatly improve the detection performance and eliminate the interference between multiple users. The traditional joint detection receiver can effectively eliminate the interference in the local cell, but it can't do anything about the interference in the neighboring cell. In order to eliminate the interference of neighboring cells, multi-cell joint detection needs to be used. [0003] There are two types of multi-cell joint detection: one is multi-cell joint detection in the training sequence (Midamble) domain, also called multi-cell joint channel estimation; the other is data domain multi-cell joint det...

[0005] It can be seen that no matter which of the above methods is used to notify the base station of the relevant information of the neighboring cells of each cell under its jurisdiction, the network planning personnel must manually configure the neighboring cell information of each cell and each frequency point. will be very large
