WIRELESS COMMUNICATION SYSTEM AND SCHEDULING METHOD FOR MULTICAST EFFICIENTLY USING ADAPTIVE MODULATION AND CODING MODE AND DIVERSITY MODE

摘要

A wireless communication system and scheduling method for effective multicast using adaptive modulation and coding mode and diversity mode are disclosed. The wireless communication system includes a user terminal group classifying unit for classifying a plurality of user terminals into two groups using a group adaptive modulation and coding (AMC) level determination algorithm, and adaptive modulation and encoding to user terminals belonging to one of the two groups. A first multicast unit for providing a multicast stream through an Adaptive Modulation and Coding (AMC) mode and a user terminal belonging to the other of the two groups and a multicast stream for providing a multicast stream through a diversity mode. It includes two multicast units.
