A wireless network with integrated scheduling of unicast and multicast users in a relay-enabled two-hop wireless network is disclosed. In this system, users with finite buffers are considered and scheduled over multiple channels in an OFDMA-based wireless network. The gain-specific and efficient scheduling system helps leverage diversity and spatial reuse gains from these networks. The system is applicable to both unicast and multicast traffic and leverages diversity and spatial reuse gains simultaneously to optimize the target network with both unicast and multicast flows. The integrated scheduling system strikes a good balance in delivering efficient performance to unicast and multicast flows.
