Abstract: LTE broadcast or evolved multimedia broadcast multicast service (eMBMS) enables operators to efficiently launch media services over LTE to meet mobile users' demand on multimedia services. This paper introduces two mechanisms that use the standard deviation (StD) of eMBMS user's modulation and coding scheme (MCS) level group operated on single cell mode to select its optimal MCS level efficiently. Typically, MCS level is selected on the basis of users' worst channel condition, which results in wasting network resources. Since the eMBMS performance directly depends on the selected MCS level, an efficient adaptive modulation and coding (AMC) scheme is essentially needed. The proposed mechanisms are simulated using LTE simulator, and the results show that the proposed mechanisms increase the eMBMS performance in terms of throughput, delay and packet loss ratio, compared to the worst channel gain and averaging mechanisms.
