Title:
Interference alignment for the transmitter / receiver pair in a radio communications system
Document Type and Number:
Japanese Patent JP6276403
Kind Code:
B2
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.
