摘要

This article proposes a Hybrid Multiple Access (HMA) transmission strategy that integrates the traditional multi-access mode and the novel uni-access mode for WCDMA downlink For better multiplexing of services with different quality requirements, this paper also proposes a quality based admission control policy and a scheduling scheme to construct an overall system for evaluation. The admission control policy is based on the mean QoS fulfillment in the target base station. The scheduling scheme is based on the delay requirement and bit-error-rate (BER) of traffic types. In the simulation study, the HMA is compared to the traditional multi-access mode WCDMA system. It is shown that the HMA outperforms the WCDMA system with better COS, lower delay, lower BER and higher throughput where last three aspects of improvement are gained by uni-access transmission mode. We also observe that the HMA provides more significant improvements when the system load is higher.
