Cooperative Resource Allocation in Multicast Networks for Outage Probability Minimization

---

In this paper, we investigate the resource allocation issues in Orthogonal frequency division multiplexing access-based multicast systems that only allows average channel state information of users to be available at the resource manager. In this system, it is impossible to guarantee
successful transmission of every data due to instant deep fading. Hence, in order to achieve efficient and reliable transmission, we exploit potential advantage provided by the cooperative diversity and propose a cooperative joint subcarrier and power allocation scheme that minimizes the probability of multicast transmission failure. This combinable allocation issue has high computational complexity, so we allocate subcarrier and power separately. We proposed cooperative proportional subcarrier allocation strategy to achieve tradeoff between throughput and fairness and iterative power (IP) allocation strategy to fully utilize the limited
power. Simulation results show that system performance of the schemes with cooperation is significantly enhanced compared with that without cooperation and the schemes with IP remarkably outperform that without.
