Systems and methods for scheduling transmission that leverages both diversity and spatial reuse gains in the presence of finite user buffers in a two-hop wireless relay setting are disclosed. The system includes partitioning a set of relays to enable spatial reuse while accounting for half-duplex nature of relays, and assigning and reusing of channels to the relays (and associated users) in the two partitions to maximize the aggregate system throughput while ensuring proportional fairness.
