Abstract

A common packet data channel (CPDC) architecture is proposed to support bursty, packet-based services in DS-CDMA integrated wireless access networks. The architecture employs a TDMA strategy in the CPDC downlink and a spread ALOHA-type random access strategy in the CPDC uplink. A congestion control algorithm using base station broadcast and portable terminal random delay call reattempt is described. A performance analysis of the CPDC architecture and algorithms is carried out, and formulae for the bit error rate, blocking probability, system delay time, and waiting time for packet data calls are derived. The capacity of a CPDC is evaluated in terms of the number of packet data subscribers that can be served with a specified grade of service (GOS)
