Abstract :
One of the main design goals of cdma2000 1xEV-DV is the efficient support of packet data services without detriment to existent voice services. This paper investigates the performance of the 1xEV-DV RL in the presence of voice users. In particular, several algorithms are investigated to support the three MAC mechanism defined in the 1xEV-DV standard. The results show that for the common rate control mechanism, the algorithm introduces no cost to mixing voice and data at low voice loads. However with the common rate control mechanism operating with higher voice load or the dedicated rate control and grant based scheduling mechanisms, the mixing of data and voice results in modest loss in performance. The amount of loss varies and is a result of the interplay of incrementally increasing resources for voice service and the ability of the system to target higher system loads as voice load increases. Nevertheless, these results show that 1xEV-DV can efficiently support both voice and packet data traffic.
