Abstract: Techniques to reduce the amount of registration required by a mobile station in a wireless communication system, especially if the registration zones are defined to be small areas. In one scheme, a mobile station registers (e.g., at R-level) with a network entity (e.g., a base station) each time it enters a new registration zone, which can correspond to an R-TMSI zone defined by GSM MC-MAP. The mobile station maintains a timer for each zone with which it has already registered but has since left. If the mobile station leaves a particular zone for a period longer than a time-out period, the registration with that zone times out, and the mobile station re-registers with that zone whenever it re-enters the zone. The mobile station may implement zone-based, timer-based, implicit, traffic channel RR, and some other registrations, or a combination thereof. Parameters to facilitate registration may be defined by a base station.

Abstract: Techniques for efficient signaling to and from a plurality of mobile stations are disclosed. In one embodiment, a subset of mobile stations may be allocated a portion (350) of the shared resource with 5 one or more individual access grants (370), another subset may be allocated a portion of the shared resource with a single common grant (370), and yet another subset may be allowed to use a portion of the shared resource without any grant. In another embodiment, an acknowledge and continue command is used to extend all or a subset of the previous grants without the need for additional requests and grants, and their associated overhead. In one embodiment, a traffic to pilot ratio (T/P) is 0 used to allocate a portion of the shared resource, allowing a mobile station flexibility in selecting its transmission format based on T/P. z z

Abstract: An efficient use of communication resources is provided by determining a behavior for selecting the payload size (data rate) of a reverse link transmission from a mobile station to a base station. The mobile station may store a predetermined table including the ratio of the power levels of the traffic channel and pilot channel (TPR), where each entry corresponds to a size of data payload, and consequently a data rate for transmission in a predetermined time frame. The payload size is selected based on an authorized-TPR. The authorized-TPR and a target-TPR are adjusted in accordance with TPR commands received from the base station. A fast-ramp-up adjustment of the authorized-TPR is carried out when the authorized-TPR is less than the target-TPR. The down TPR commands are ignored in the adjustments of the authorized-TPR upon fast-ramp-up mode.

Abstract: Systems and methods for controlling a data rate of a transmission in a wireless communication system during handoff are described herein. In some embodiments, controlling the data rate includes receiving transmissions from a plurality of base stations, wherein each received transmission includes a data rate control indicator, and adjusting the data rate of the transmission during handoff based on the data rate control indicators from the plurality of base stations.

Abstract: Embodiments disclosed herein address the need in the art for an extended acknowledgment/rate control channel. In one aspect, an acknowledgment command and a rate control command are combined to form a combined command. In another aspect, the combined command is generated in accordance with a constellation of points, each point corresponding to a pair consisting of a rate control command and an acknowledgment command. In yet another aspect, the points of the constellation are designed to provide the desired probability of error for the respective command pairs. In yet another aspect, a common rate control command is transmitted along with a combined or dedicated rate control command. Various other aspects are also presented. These aspects have the benefit of reduced overhead while providing acknowledgment and rate control to single remote stations and/or groups of remote stations.

Abstract: Embodiments disclosed herein address the need in the art for reduced overhead control with the ability to adjust transmission rates as necessary. In one aspect, a first signal indicates an acknowledgement of a decoded subpacket and whether or not a rate control command is generated, and a second signal conditionally indicates the rate control command when one is generated. In another aspect, a grant may be generated concurrently with the acknowledgement. In yet another aspect, a mobile station monitors the first signal, conditionally monitors the second signal as indicated by the first signal, and may monitor a third signal comprising a grant. In yet another aspect, one or more base stations transmit one or more of the various signals. Various other aspects are also presented. These aspects have the benefit of providing the flexibility of grant-based control while utilizing lower overhead when rate control commands are used, thus increasing system utilization, increasing capacity and throughput.

Abstract: Method and apparatus for congestion control in a wireless communication system. In one embodiment, the status of a congestion bit indicates the type of adjustment, such as increase or decrease, to be performed at an access terminal to determine the next data rate for transmissions on the reverse link. The status of the congestion bit is determined by comparing a congestion parameter to a predetermined threshold (186). One embodiment implements an outerloop threshold having a margin with respect to the desired congestion metric threshold. The outerloopthreshold is adjusted in response to comparing a measured congestion metric to the desired threshold (192, 194, 196). The outerloop threshold adjustment maintains the congestion metric to within a predetermined probability of exceeding the desired threshold.
