This report introduces a resource allocation algorithm for multicasting compressed video packets over orthogonal frequency division multiplexing channel. Multicasting has advantage of supporting multiple users with a single data transmission. However, inefficiency also can occur, since high transmission quality for users with low channel quality also have to be guaranteed. Therefore, this report introduces an algorithm for selecting users to be supported and modulation level for each subchannel so as to maximize total bit rate. Since each channel supports different set of users, total bit amount of each user can be diverse. Therefore, medium grain scalable video coding supporting bit rate adaptation is considered. The video packets are loaded to the configured radio resources. |
