Abstract :
Cooperative multi-cell transmit strategies typically require full channel state information (CSI) at the base station. Most previous works in this area have assumed that base stations have common knowledge of both data dedicated to all terminals and full or partial CSI of all links. In this paper, a more practical limited-feedback scenario is studied for multi-cell joint beamforming. The proposed algorithm provides higher sum rates over the virtual SINR one.
