Evaluation of multicast scheduling and clustering schemes with packet-level macro diversity in high-speed cellular networks

Résumé

This paper targets multicast packet-switched transmission on the downlink radio interface using the multicast mode. In the multicast mode, a packet is sent simultaneously to several terminals in the same cell. In order to increase the received SNR, we consider different techniques of macro diversity, namely Selective Combining (SC) and Maximal Ratio Combining (MRC). We develop an analytical model that allows the computation of the throughput for different multicast schedulers with SC and MRC schemes. These schedulers offer different trade-offs between throughput and fairness. We also introduce an efficient user clustering strategy considering their average radio channel quality. The study shows that macro diversity improves the transmission performance especially for pure multicast.
