N2 - Broadcast (or point to multipoint) communication has attracted a lot or research recently. In this paper, we consider the group broadcast channel where the users' pool is divided into groups, each of which is Interested In common Information. Such a situation occurs Tor example In digital audio and video broadcast where the users are divided Into various groups according to the shows they are Interested In. The paper obtains upper and lower bounds for the sum rate capacity In the large number of users regime and quantifies the effect of spatial correlation on the system capacity. The paper also studies the scaling of the system capacity when the number of users and antennas grow simultaneously.
