N2 - The next-generation packet-based wireless cellular network will provide real-time services for delay-sensitive applications. To make the next-generation cellular network successful, it is critical that the network utilizes the resource efficiently while satisfying quality of service (QoS) requirements of real-time users. In this paper, we consider the problem of power control and dynamic channel allocation for the downlink of a multi-channel, multi-user wireless cellular network. We assume that the transmitter (the base-station) has the perfect knowledge of the channel gain. At each transmission slot, a scheduler allots the transmission power and channel access for all the users based on the instantaneous channel gains and QoS requirements of users. We propose three schemes for power control and dynamic channel allocation, which utilize multiuser diversity and frequency diversity. Our results show that compared to the benchmark scheme, which does not utilize multiuser diversity and power control, our proposed schemes substantially reduce the resource usage while explicitly guaranteeing the users' QoS requirements. © 2006 IEEE.
