SYSTEMS AND METHODS FOR LEVERAGING SPATIAL REUSE IN OFDMA RELAY NETWORKS

摘要

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.
