Scheduling multi-user MIMO communication based on physical channel parameters

Efficiently scheduling the optimal multi-user multiple-input multiple-output links presents a considerable challenge since it depends upon accurate knowledge of the multi-user channel state information and involves significant computational complexity. This paper demonstrates a technique for efficiently scheduling based on a few key parameters that describe the physical nature of multi-user propagation channels. Simulations demonstrate that the scheduling technique is able to achieve average network sum rates that approach those of the optimal link topology, particularly when latency associated with finite computational resources is considered.
