In this paper, a rate-based admission control scheme for a single shared wireless base station with opportunistic scheduling and adaptive modulation and coding (AMC) is proposed. The proposed admission scheme maintains minimum average rates of the admitted users, i.e., new users will be admitted if the base station has enough resources to support the required minimum average transmission rates of all users. The proposed scheme relies on an analytical model for the average per-user rates of an

We provide extensive simulation results to demonstrate the accuracy of the base analytical model on which our admission scheme relies.
