Admission control of integrated voice and data CDMA/TDD

Abstract

This paper researches an admission control scheme of integrated voice and data CDMA/TDD system considering asymmetric traffic and power limit. A new user can access the system only if the outage probabilities it experiences on the uplink and downlink time slots are below a threshold value. Based on the power limit the results show the voice and data blocking probabilities under different cell coverage radius, classes of calls and arrival rates. The system performances are also compared under various uplink/downlink time slot allocation patterns. Furthermore, multicode and multislot schemes are proposed and evaluated under the presented admission control scheme.
