Future third-generation mobile communication systems will need MAC protocols suitable for multimedia CDMA radio communications. DQRAP/CDMA (distributed queueing random access protocol/CDMA) is a general purpose MAC protocol oriented to the CDMA environment. Analytical model expressions and computer simulations have shown its capacity to achieve near-optimum performance under certain traffic scenarios. Starting from the DQRAP/CDMA specification presented in Alonso et al. (2000), we propose some algorithm modifications in order to further improve the system performance when the traffic load is extremely bursty. Computer simulations have been carried out to evaluate this performance improvement
