摘要：

This paper considers downlink transmit beamforming for a unicast transmission to a multitude of users with the goal of a joint optimization of the beamforming weights from multitude of basestations. In wireless systems, bandwidth is a limited resource. Therefore in this paper, a frequency reuse-1 is applied at the expense of intercell interference. The optimization of the beamforming weights is done with semidefinite programming with the knowledge of long term channel state information (CSI). This paper presents a fair beamforming technique that results in a very low signal to interference and noise rate (SINR) feedback rate. An improvement of the throughput for users in the cell edge region with a constrained transmit power is achieved.
