Outage Analysis for Multi-connection Multiclass Services in the Uplink of Wideband CDMA Cellular Mobile Networks

摘要

In this paper, we address the data link layer quality of service (QoS) issue by investigating the outage probabilities for multi-connection multiclass services in the uplink of a wideband CDMA cellular mobile network. Four Universal Mobile Telecommunications System (UMTS) QoS classes are served within each mobile user simultaneously. Each class has different QoS constraints. Assuming perfect power control, a power allocation scheme is designed to fulfill the desired received powers for all traffic classes. The outage probability is formulated for each mobile user with its traffic classes in terms of bit error rate (BER) and signal-to-interference-plus-noise ratio (SINR). In addition, an admission region, satisfying the outage probability requirements of all mobile users, is computed.
