METHOD AND APPARATUS FOR INTERFERENCE PROCESSING IN WIRELESS COMMUNICATION SYSTEM
First Claim
1. A method of operating a master node for interference processing in a wireless communication system, the method comprising:
- determining an interference-alignment dimension to use to perform interference alignment based on a number of antennas of a plurality of transmitters and a number of antennas of a plurality of receivers;
distributing a dimension remaining after determining the interference-alignment dimension to a plurality of transmission/reception links;
determining a non-interference-alignment dimension not used to perform the interference alignment based on the dimension distributed to the plurality of transmission/reception links;
determining at least one matrix for interference alignment of the plurality of transmitters and the plurality of receivers based on channel information about the plurality of transmitters and the plurality of receivers, the interference-alignment dimension, and the non-interference-alignment dimension; and
transmitting the determined at least one matrix to at least one of the plurality of transmitters and the plurality of receivers.
