INTERFERENCE ALIGNMENT FOR TRANSMITTER/RECEIVER PAIRS IN WIRELESS COMMUNICATION SYSTEMS
First Claim
1. A method comprising:
- selecting second transmitter-receiver pairs proximate a first transmitter-receiver pair, wherein the first transmitter-receiver pair is in a first cell and the second transmitter-receiver pairs are not in the first cell; and
aligning signals transmitted by the second transmitter-receiver pairs to be received by the first transmitter-receiver pair in a first subspace of channels, wherein a second subspace of the channels is free of the signals transmitted by the second transmitter-receiver pairs.

Abstract
Interference is mitigated in a wireless communication system using interference alignment techniques to cancel inter-cell interference based on a decoding order while using joint decoding to cancel intra-cell interference. Second transmitter-receiver pairs proximate a first transmitter-receiver pair may be selected so that the first transmitter-receiver pair is in a first cell and the second transmitter-receiver pairs are not in the first cell. Signals transmitted by the second transmitter-receiver pairs may be aligned to be received by the first transmitter-receiver pair in a first subspace of channels. A second subspace of the channels is free of the signals transmitted by the second transmitter-receiver pairs.
