Abstract

In this letter, using a utility-based approach we formulate the optimal downlink resource allocation problem for non-realtime traffic in a CDMA/TDMA cellular network. We then introduce the notion of multi-access-point diversity which is a potential form of diversity in cellular networks, where a signal can be transmitted to the corresponding mobile user via multiple base-stations. A joint base-station assignment and packet scheduling method is then proposed which exploits multiaccess-point and multi-user diversity in one shot. The simulation results of the proposed method show significant throughput improvement due to multi-access-point diversity gain.
