On Rate Assignment Schemes for the Reverse Packet Data Channel in cdma2000 1xEV-DV

The capacity demands required to handle new wireless services such as e-mail, web surfing, and video streaming led to a new era of wireless technologies. cdma2000 1xEV-DV is considered to be the solution for the ever-growing demand of high-speed wireless packet data transmission. We investigate several aspects related to autonomous rate assignment schemes over the cdma2000 1xEV-DV reverse packet data channel. In particular, based on the developed rise over thermal model, we provide an upper bound for the reverse packet data channel throughput as a function of the number of mobile stations that are allowed to transmit instantaneously on each time slot. We also propose several autonomous rate assignment schemes that provide a significant throughput improvement relative to other published schemes.
