Abstract: Techniques for performing duplicate detection and re-ordering for a HARQ transmission are described. For duplicate detection, a receiver determines whether a decoded packet x for an ARQ channel y is a duplicate packet based on packet x and a prior decoded packet for ARQ channel y. For re-ordering, the receiver determines whether an earlier packet is still pending on any other ARQ channel based on prior decoded packets for the ARQ channels and forwards packet x only if there are no pending earlier packets. There are no pending earlier packets on another ARQ channel z if (1) a decoded packet was received on ARQ channel z at a designated time or later or (2) a decoded packet was not received on ARQ channel z within a time window from current time.

Abstract: In accordance with an exemplary embodiment of the invention, an apparatus, system, and method efficiently manage reverse link resources by allowing a mobile station to select between transmitting a payload a standard power level and transmitting a smaller payload at a boosted power level. The mobile station, therefore, can autonomously select a QoS (Quality of Service) level for physical layer packets. Based on reverse link transmission information received from a base station, the mobile station derives a reverse link transmission guideline defining the power levels and associated payloads for at least a standard service and boosted service. The mobile station selects a reverse link transmission power level from a plurality of power levels including at least a standard reverse link transmission power level associated with a standard payload size and a boosted reverse link transmission power level associated with a boosted payload size where the standard payload size is greater than the boosted payload size.

Abstract: An apparatus, system, and method efficiently manage reverse link communication in a communication system having geographically distributed base stations. A base station functioning to at least one mobile station as a non-serving active base station estimates an expected coupled load due to the at least one mobile based on a previous total coupled load. The base station determines a total available capacity based on the difference between the total capacity of the base station and the estimated expected coupled load. The base station allocates reverse link resources to other mobile stations served by the base station so as not to exceed the total available capacity. Since the allocation of reverse link channels resources are controlled directly by the base station, delays due to communications with a central controller are eliminated. As a result, adverse effects of load scheduling based on obsolete reverse channel information are minimized.

Abstract: An apparatus, system, and method efficiently manage reverse link communication in a communication system having geographically distributed base stations. Coupled load information is exchanged between base stations allowing a base station to determine an appropriate allocation of reverse link channel resources to mobile stations served by the base station. Since the allocation of reverse link channels resources are controlled directly by the base station, delays due to communications with a central controller are eliminated. As a result, adverse effects of load scheduling based on obsolete reverse channel information are minimized.

Abstract: A system and method for a time-scalable priority-based scheduler. A flexible scheduling algorithm utilizing variable scheduling durations enables better system capacity utilization. A rate request (408) is transmitted if data arrives in a buffer, data in the buffer exceeds a buffer depth, and sufficient power exists to transmit at the rate requested. A rate assignment (418) responsive to the rate request indicates a scheduled duration and a scheduled rate applicable for the scheduled duration. The scheduled duration is less than or equal to a scheduling period (508). The scheduling period is an interval of time after which a scheduler makes a scheduling decision. The scheduling period is variable and the scheduled duration is variable. The scheduler is preferably applied in a UMTS, CDMA 2000 or HDR-system for reverse link rate scheduling.

Abstract: Method and apparatus for congestion control in a wireless communication system. Individual target data rate values are assigned individual access terminals. The individual data rates of the access terminals are adjusted to achieve the corresponding individual target data rate values (208, 218). If the target values are not achieved within a predetermined number of iterations, the individual data rate is adjusted. In one embodiment, the status of a congestion bit indicates the type of adjustment, such as increase or decrease (204), wherein the status of the congestion bit is determined by comparing a congestion parameter to a predetermined threshold. One embodiment implements an outerloop threshold having a margin with respect to the desired congestion metric threshold. According to one embodiment, a congestion indicator includes multiple bits, wherein at least one bit instructs the mobile station to use target values or else to adjust without regard to a target value (210, 216).
