CSIT sharing over finite capacity backhaul for spatial interference alignment
M Rezaee, M Guillaud… - 2013 IEEE International …, 2013 - ieeexplore.ieee.org
Cellular systems that employ time division duplexing (TDD) transmission are good
candidates for implementation of interference alignment (IA) in the downlink since channel
reciprocity enables the estimation of the channel state by the base stations (BS) in the uplink
phase. However, the interfering BSs need to share their channel estimates via backhaul
links of finite capacity. A quantization scheme is proposed which reduces the amount of
information exchange (compared to conventional methods) required to achieve IA in such a …
