Abstract	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 which is based on an approximated closed-form power control feasibility condition (PCFC). Analytical and simulation results show that a significant performance improvement in terms of blocking probability and connection delay can be achieved by employing multiple antennas at a base-station (BS). An efficient reduced-outage-probability (ROP) algorithm is proposed to reduce the outage in the physical layer
