Focusing on the uplink, where mobile users (each with a single transmit antenna) communicate with a base station with multiple antennas, we treat multiple users as antennas to enable spatial multiplexing across users. Introducing distributed closed-loop spatial multiplexing with threshold-based user selection, we propose two uplink channel-assigning strategies with limited feedback. We prove that...
Assuming a base station with multiple antennas, we propose two channel-assigning strategies based on spatial multiplexing with threshold-based user selection at the uplink. Allowing multiple chosen users to access the channel, we obtain additional multiplexing gain and a reduced feedback complexity, compared to the conventional greedy approach. We prove that the proposed system outperforms the greedy...
