Long Term Evolution (LTE) network provides a high throughput with low latency\nwhich make it suitable for multicast and broadcast services. In Conventional Multicast Scheme\n(CMS), data is transmitted according to the user with worst channel condition which results in\nwasting network resources. To overcome the drawback of CMS, a new subgrouping\nmechanism is proposed to split the multicast group into several subgroups based on users\nchannel quality. The performance of the proposed mechanism has been evaluated using LTE\nsimulator. The simulation results show that the proposed mechanism increase the multicast\nperformance compared to CMS in term of goodput and spectrum efficiency, while maintain\nfairness index of users in an acceptable level.
