چکیده

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.

Location-Dependent Other-Cell Interference and Its Effect on the Uplink Capacity of a Cellular CDMA System

We consider the other-cell interference evaluation problem in a multi-cell CDMA system by looking at its location-dependence on the location distributions of mobile users in the cells. The goal is to characterize the location-dependent availability of radio resources in CDMA cellular networks. We model the locations of mobile users in a CDMA cell statistically by assuming certain location proba...
