Abstract
This paper investigates the problem of scheduling of antenna and user for the uplink MIMO/FDD system. Upper bound for sum capacity is found via considering all combinations of antenna and user. We suggest two different scheduling algorithms such as max-SNR and max-SINR that schedule user and antenna based on the instantaneous SNR and SINR of each antenna stream. The performance of sum capacity with those proposed schedulers approaches upper bound while providing the reduction of scheduling complexity.
