Abstract

We study in this paper uplink scheduling for V-BLAST users. Each user spatially multiplexes his data over multiple transmit antennas. This spatial multiplexing (SM) scheme provides high data rates while multi-user diversity obtained from scheduling improves the performance of the uplink system. The scheduler selects one user at a time based on a criterion that minimizes aggregate BER. The main results of this study show that the scheduler that maximizes the optimal MIMO capacity doesn 't work well for a V-BLAST system. Instead, a scheduler that maximizes the V-BLAST capacity is derived specifically from the V-BLAST detection algorithm. Furthermore, we propose and compare suboptimal schedulers that are based on the received MIMO channels before processing.
