A Resource Allocation Algorithm for OFDM-Based Cellular System Serving Unicast and Multicast Services
In this paper, the authors propose a resource allocation algorithm for orthogonal frequency division multiplexing-based cellular system that serves users each of which requests a regular service or a Multimedia Broadcast Multicast Service (MBMS). They assume that the MBMSs are considered for video services such as mobile TV. In order to efficiently serve the users with heterogeneous channel conditions, thus employed channel-adaptive video streams by using Scalable Video Coding (SVC), where a realistic multicast configuration is considered for multicasting the SVC streams. Therefore, they designed the cellular system to serve constant and flexible bit rates for the regular services and the MBMSs, respectively.
