Packet reservation multiple access (PRMA) is a famous packet switching based medium access control (MAC) for its high multiplexing gain, which is further enhanced by jointly using code-division multiple access (CDMA). In most studies on CDMA/PRMA for uplink time-division duplexing (TDD) cellular networks, perfect power control is assumed and each time slot is divided into fixed number of code slots. It is always assumed that this capacity of a time slot can be fully utilized. However, in practice the mobile stations (MSs) have limited transmit power levels, which will limit the system capacity. In this Paper, we investigate the impact of limited transmit power levels on the performance of CDMA/PRMA and propose a practical power control algorithm. Multimedia traffic is considered, which consists of conventional voice traffic and worldwide web (WWW) browsing traffic. Simulation results reveal that the performance of CDMA/PRMA in cellular networks degrades as the cell radius increases and for small cell radius (e.g. ≤ 750m), it provides good system capacity even when multimedia traffic is present.
