    摘要： In a disclosed embodiment, signal levels of the active sectors of an access terminal are compared with the signal level of the current serving sector of the access terminal. Next, a delta credit is accumulated. If a DRC lock bit is available, then an accumulated total credit is authorized to produce an authorized accumulated total credit. Afterwards, a new serving sector is identified from a pool of candidate sectors based on the signal levels of the active sectors and the authorized accumulated total credits.

    摘要： 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.

    摘要： An apparatus and method for transmit power savings comprising determining a rate of a previous frame; determining if a current frame is an ALWAYS-ON frame, wherein the current frame temporally succeeds the previous frame; and either ignoring every other reverse link power control (RLPC) bits received on a forward power control subchannel (F-PCSCH) or applying every RLPC bits received on the F-PCSCH. In one aspect, the apparatus and method for transmit power savings comprising using a rate determination algorithm (RDA) to determine a rate of a previous frame; detecting a pilot gating pattern at the end of the previous frame; comparing the rate of the previous frame to a threshold; determining if a current frame is an ALWAYS-ON frame; and declaring the current frame to be a 0 bps frame and puncturing the F-PCSCH to a predetermined frequency.

    摘要： Embodiments disclosed herein relate to methods and systems for providing adaptive server selection in wireless communications. An access terminal may be 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 access terminal belong to different cells. The access terminal may be further configured to change a data rate control (DRC) cover in accordance with the DSC change. The use of DSC may provide an early indication of handoff, thereby allowing the service outage associated with server switching to be substantially reduced.
