【 摘 要 】

Resource allocation in wireless cellular networks has been an important and challenging issue. With the rapid development of wireless communications, more and more mobile multimedia and innovative applications (e.g. augmented reality and video conferences) have emerged, which are suitable for wireless broadcast and have requirements on transmission delay. In this paper, we focus on delay-constrained multi-cell broadcast networks, taking user mobility into consideration for future channel estimation. The promising network coding technique is also adopted to improve transmission efficiency. The objective is to minimize total transmission energy consumption via joint resource allocation and scheduling optimization. Both optimal and heuristic solutions are proposed. Simulation results show that the proposed schemes perform better than other benchmark schemes, in terms of transmission energy consumption and success rate.
