We investigate the resource allocation problem in heterogeneous cooperative OFDMA systems. In contrast to existing literature, which mainly focuses on best effort (BE) services or non-real-time (nRT) services, we consider real-time (RT) services with strict delay and rate requirements. Exploiting the wireless channel and queue information, a utility-based optimization problem is formulated for dynamic subcarrier allocation and relay selection supporting mixed BE and RT services. An efficient… CONTINUE READING
