Abstract

This letter addresses the problem of feedback load reduction for opportunistic multicast scheduling (OMS) in OFDM-based systems. We investigate two scenarios, multicast service with large group size and multicast service with small group size, and derive two practical schemes respectively. The superiorities of the proposed schemes are: 1) no precise knowledge of the wireless fading channel is required, and 2) feedback load can be significantly reduced while the throughput performance remains comparable with the case of full feedback.
