    Abstract: An apparatus and method for adjusting a power control setpoint for a power control mechanism with a first state and a second state in a wireless communication system. The method comprises: determining the state of the power control mechanism; when the state of the power control mechanism is the first state, adjusting the power control setpoint in accordance with a first adjustment scheme; and when the state of the power control mechanism is the second state, adjusting the power control setpoint in accordance with a second adjustment scheme.

    Abstract: Embodiments disclosed herein relate to methods and systems for providing adaptive server selection in wireless communications. In an embodiment, an access terminal is configured to determine a forward link quality metric associated with each of a plurality of sectors serviced by a plurality of access points; assign credits to each sector in relation to the forward link quality metric; and change a data source control (DSC) value if the credits accumulated for a non-serving sector at a DSC change boundary is greater than a predetermined threshold, where the non-serving sector and the serving sector for the AT belong to different cells. The access terminal is further configured to change a data rate control (DRC) cover in accordance with the DSC change. The use of DSC provides an early indication of handoff, thereby allowing the service outage associated with server switching to be substantially reduced. A method for handoff is further disclosed using DSC as early indication of handoff, which also trigger multitasking forward traffic for the access terminal to all access points.

    Abstract: A method for wireless communication, comprising: receiving data in multiple forward link timeslots; determining a quality metric of the received data; requesting retransmission of the data via a first request scheme if the quality metric indicates the data has not been received correctly; and if retransmission is requested and the data is not received correctly, requesting retransmission of the data via a second request scheme.

    Abstract: An apparatus for selecting a best serving sector in a code division multiple access (CDMA) communication system. A comparator compares a plurality of signal levels received from a plurality of active sectors with a signal level of a current serving sector to produce a difference. A delta generator is coupled to the comparator that generates a delta credit for each of the plurality of active sectors based on the difference. An accumulator is coupled to the delta generator and accumulates a plurality of delta credits to produce an accumulated total credit. A best sector identifier that is coupled to the accumulator identifies the best serving sector from the accumulated total credit.
