Adaptive Bit Partitioning for Multicell Intercell Interference Nulling with Delayed Limited Feedback
Ramya Bhagavatula, Robert W. Heath
Base station cooperation can exploit knowledge of the users' channel state information (CSI) at the transmitters to manage co-channel interference. Users have to feedback CSI of th…

Adaptive Limited Feedback for Sum-Rate Maximizing Beamforming in Cooperative Multicell Systems
Ramya Bhagavatula, Robert W. Heath
Base station cooperation improves the sum-rates that can be achieved in cellular systems. Conventional cooperation techniques require sharing large amounts of information over fini…
