An Optimal Admission Control Policy for CDMA Multiple Antenna Systems with QoS Constraints

Abstract— An optimal admission control (AC) policy is proposed for a CDMA multiple antenna system, which can maximize the system throughput while simultaneously guaranteeing all quality-of-service (QoS) requirements in both physical and network layers. While previous research can only ensure the QoS requirements for appropriately chosen automatic-retransmissionrequest (ARQ) parameters, the proposed AC policy aims to ensure the QoS requirements for arbitrary ARQ parameters, which saves system resources. Numerical examples show that the proposed AC policy can achieve a significant performance gain in terms of network layer performance as well as system throughput.
