Power control is a key air-interface management mechanism for any multiple-access CDMA-based wireless air-interface. Typically it has been used to ensure a target packet-error-rate (PER) for any user connection. In the presence of hybrid-ARQ (HARQ) on the reverse link (as in 3GPP2's EVDO-Rev A), there is additional flexibility that a power control implementation can utilize to ensure quality-of-service (QoS) for any connection. This paper discusses a general framework in which this can be done. It further provides an easily implement able algorithm within this framework, and substantiates its efficacy with simulations.
