Flexible Broadcasting of Scalable Video Streams in Broadband Wireless System
In this paper, the authors present a novel cross-layer optimization framework to improve the Quality Of user Experience (QOE) and energy efficiency of the heterogeneous wireless multimedia broadcast receivers. User grouping is based on the respective UE resolution capabilities and received SNR. A UE capability is determined by the BS at the time of service subscription, when the UE sends its type information, i.e., the number of layers it wants to receive. The UE periodically updated its channel condition to the BS through the uplink channel.
