Concurrent presence of inter-cell and intra-cell interferences constitutes a major impediment to reliable downlink transmission in multi-cell multiuser networks. Harnessing such interferences largely hinges on two levels of information exchange in the network: one from the users to the base-stations (feedback) and the other one among the base-stations (cooperation). We demonstrate that exchanging...
In this paper, we propose a new signal dimensioning scheme for multi-user MIMO downlink, that adjusts the signal dimensions for different users to maximize the system throughput. By adapting the signal dimensions, we can achieve better tradeoff between multiplexing and diversity, and obtain much better bit rate error performance and higher capacity.
