Efficient resource management for packet mode cdma2000

Abstract

SUMMARYMobile systems have recently evolved from being simple devices used for voice communications to systems that support new features such as data transmissions, video streaming and Internet access. The capacity demands to handle these new services 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. In this paper, we investigate several aspects related to resource management techniques over the cdma2000 1xEV-DV reverse packet data channel (R-PDCH). In particular, based on the developed rise over thermal (RoT) model, we provide an upper bound for the R-PDCH throughput as a function of the number of mobile stations (MSs) that are allowed to transmit instantaneously on each time slot. We also provide a lower bound for the average sector throughput based on the number of users per sector. We propose several autonomous rate assignment, and scheduling techniques that provide a significant throughput improvement relative to other published techniques.
