In this paper, a downlink communication system, in which a Base Station (BS) equipped with M antennas communicates with N (N ≫ 1) single-antenna users, in a Rician fading environment is considered. The asymptotic (in terms of the number of users) sum-rate capacity of the system, as well as the capacity-achieving strategies, are derived. The main results of the paper are as follows: i) in the region of K = o(log N ), where K denotes the Rician factor, the sum-rate capacity scales as M log(1 + P
