Uplink Resource Allocation for Multicarrier CDMA Networks with Interference Cancellation

We formulate the uplink resource allocation problem in CDMA wireless networks with interference cancellation in the load domain, which is an exact linearization of the single- cell single-carrier loading and transmit power feasibility constraints. We present a simple cooperative distributed algorithm that solves the single-cell allocation problem when posed in a utility-maximizing framework, and relate it to the uplink allocation design of the cdma2000 1xEV-DO Rev A system. We extend to the multicarrier uplink allocation problem and discuss conditions under which allocation convexity is preserved. We provide guidelines on how the results generalize to the multicarrier multi- cell network allocation problem, and how full resource allocation expressibility has been incorporated into the 1timesEV-DO Rev B uplink design. Though 1timesEV-DO examples are used throughout, the analytic approach of this paper applies to any CDMA uplink, including WCDMA.
