摘要： Adaptive delay management means and method for allocating resources having different Quality of Service (QoS) requirements. A Forward Link (FL) scheduler prepares transmission instances by treating pending data queues according to a priority class, such as Best Effort (BE) and Expedited Forwarding (EF). Data bits from multiple queues are stuffed into a transmission instance. Various metrics are used to generate a set of candidates for transmission and then select and build a next transmission instance from the set of candidates.

摘要： Techniques for supporting broadcast/multiple transmission to multiple terminals with feedback and rate adaptation are described. In an aspect, a combination of HARQ and at least one shared feedback channel may be used to support broadcast/multicast transmission. In one design, a base station may send at least one transmission of a packet to multiple terminals, one transmission at a time. The base station may receive feedback information (e.g., NAK) for the packet from the terminals on the shared feedback channel(s). The base station may determine whether to terminate the packet early and/or may select at least one transmission parameter for another packet based on the feedback information for the packet. In another aspect, a transport format for a broadcast/multicast transmission may be selected based on CQI information from terminals receiving the transmission. The terminals may send CQI information at a slow rate and/or only certain terminals may send CQI information.

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.
