Abstract

The invention provides an interference aligning method of wireless network. The method comprises the transmission freedom degrees that can be supported by transmission links in three cells are identified; ordering is carried out according to the transmission freedom degrees; a freedom degree relation area in which the transmission links L1, L2 and L3 are positioned is determined according to the transmission freedom degrees; according to the freedom degree relation area, a precoding matrix W1 of the transmission link L1, a precoding matrix W2 of the transmission link L2 and a precoding matrix W3 of the transmission link L3 are calculated respectively; the precoding matrix W1 is back fed to the sending end of the transmission link L1; the precoding matrix W2 is back fed to the sending end of the transmission link L2; and the precoding matrix W3 is back fed to the sending end of the transmission link L3. According to the invention, the problem in interference management in the cell edge is solved, the network throughput is higher, and realization is easier.

Description

Technical field [0001] The present invention relates to the technical field of interference management of wireless communication systems, and in particular to an interference alignment method suitable for multi-cell wireless networks. Background technique [0002] Co-frequency networking is the main networking form of wireless communication networks, and higher network capacity can be obtained through frequency reuse. However, in the co-frequency networking mode, there are serious co-frequency interference problems in the edge areas of adjacent cells, which further reduces the performance and user experience of edge users. How to efficiently solve the problem of co-channel interference has always been a research direction that academia and industry are paying attention to. Currently, typical interference management methods include: [0003] (1) Interference management through resource orthogonalization: [0004] The orthogonalization of transmission resources is the main method of...
