A throughput-maximization call admission control (CAC) policy is proposed for CDMA beamforming systems in which the QoS requirements in both physical and network layers can be guaranteed. While the existing cross-layer CAC policies rely on a separate reduced-outage-probability (ROP) algorithm to guarantee the physical layer QoS requirement, which adds to system complexity and reduces spectral efficiency,...
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-retransmission-request (ARQ) parameters, the proposed AC policy...
In this paper, we extend the optimal call admission control (CAC) algorithm proposed in Comaniciu, C et al., (2003) to code-division multiple access (CDMA) beamforming systems. In the closed-form power control feasibility condition cannot be readily extended to CDMA beamforming systems, and thus the optimal CAC policy cannot be applied directly. In this paper, we derive a sub-optimal CAC algorithm...
