Performance of the Medium Access Control Protocol for the High Speed Downlink Packet Access

Overview In this paper, the Medium Access Control (MAC) protocol for the High Speed Downlink Packet Access (HSDPA) of the Wideband CDMA (WCDMA) radio transmission is studied. In a packet radio network, the delay performance is of special interest. HSDPA is a new concept, which enhances downlink performance of the WCDMA air interface to lower packet delays and higher throughput. The HSDPA MAC protocol is shortly introduced and its impact to the buffering requirements is studied. The retransmission probability and Transport Format selection probability are presented as distributions. Finally, the performance results are analysed from the simulated measures of packet delay distributions and window occupancy distributions.
