Title:
INTERFERENCE SUPPRESSION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/147561
Kind Code:
A1
Abstract:
Provided are an interference suppression method and apparatus, which are used for reducing the time consumed during an interference suppression process. The method comprises: a base station acquiring forming coefficient vectors of n paired terminal devices, determining a forming vector matrix according to n forming coefficients, and calculating a channel correlation matrix of the n terminal devices according to the forming vector matrix; the base station determining a channel correlation inverse matrix according to the channel correlation matrix; the base station performing flow power adjustment processing on the channel correlation inverse matrix to obtain an adjustment matrix of the channel correlation inverse matrix, and then obtaining an interference suppression matrix according to the forming vector matrix and the adjustment matrix of the channel correlation inverse matrix; and the base station performing interference suppression processing on the n terminal devices according to the interference suppression matrix. In the method, a computation amount during an interference suppression processing process is greatly reduced by placing a flow power processing process of an interference suppression matrix such that same is after an inverse matrix, thereby reducing the time consumed for a system to execute interference suppression and improving the performance of the system.
