A Resource Allocation and Admission Control Scheme for Multimedia Services in Broadband Wireless Communication Systems

In this paper, we develop a resource allocation and admission control scheme for multimedia services downlink transmission in a multiple parallel time-varying subchannels circumstance such as that in current orthogonal frequency division multiplexing (OFDM) and multi-input multi-output (MIMO) systems. We introduce the outage probability to characterize the influence of both the bursty nature of multimedia traffic and the uncertainty of wireless capacities on resource allocation and then correlate it to the connection dropping probability factor in the quality-of-service (QoS) requirements. In order to utilize the scarce wireless resource efficiently, as many users as possible should be admitted into the network while providing guaranteed QoS support for them. By integrated multiuser diversity and space-frequency diversity scheduling, we analysed the outage probabilities under the maximum SNR scheduling scheme. By simulation results, superiorities in system utilization efficiency of our scheme are verified
