Abstract
Disclosed is method for controlling interference in a wireless system having multiple sending and receiving nodes. In the method for controlling interference in a wireless system having multiple sending and receiving nodes, a plurality of receiving nodes share each other's channel information, each of the receiving nodes uses the shared channel information to calculate a precoding matrix which is fed back to the sending nodes, and each of the sending nodes uses each of the precoding matrices received as feedback to transmit a send signal to the receiving nodes, thereby controlling interference. Complete interference alignment can be achieved even by just sharing channel information between receiving nodes, and the invention can be employed not only for inter-cell interference but also for intra-cell interference environments.
