In this paper, we present new feedback reduction schemes that reduce the feedback load needed for opportunistic scheduling in the multicast OFDMA system. Considering the characteristics of the multicast system that the feedback of the user with the poorest channel condition dictates the transmission rate, we designed the proposed schemes such that it can reduce the total feedback load by sacrificing...
In this paper, we present two new feedback schemes, namely the network mode selection-based feedback (NMF) and the user mode selection-based feedback (UMF), that reduce the feedback load needed for opportunistic scheduling in the OFDMA downlink system. The two schemes are designed to select either the selective feedback (SF) mode which feeds back the fine-grained condition of a part of the channels...
