Scheduling in a broadcast channel based on partial channel-state-information at the transmitter is carried out in an opportunistic way. In this paper, the number of generated beams...
Abstract—In this paper we aim to solve the multiuser multiinput multi-output (MIMO) downlink beamforming problem. The transmitter is a multi-antenna base-station broadcasting to ...
— The communication between a multiple-antenna transmitter and multiple receivers (users) with either a single or multiple-antenna each can be significantly enhanced by providin...

—Opportunistic scheduling in random beamforming maximizes the sum-rate by allocating resources to the users with the best channel condition, thus leveraging on multiuser diversit...
Abstract— Adaptive transmission techniques including transmit beamforming, precoding, and opportunistic scheduling offer high spectral efficiency when channel state information ...
