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: Systems and techniques for communications wherein a data packet is transmitted over at least one time slot from a transmission site, a value is computed from an initial value and information, the initial value being a function of the number of time slots of the data packet transmission, the value and the information is transmitted from the transmission site, the transmitted value and the information is received at a receiving site, the value from the received information is recalculated, and the number of time slots of the data packet transmission is determined from the calculated and recalculated values.

Abstract: Techniques for improved margin control in a data communication system are disclosed. In one aspect, margin is adjusted in response to a first subpacket error rate (350). In another aspect, margin is further adjusted in response to an overall packet error rate (350). In yet another aspect, the first subpacket error rate is adjusted in response to an overall packet error rate (350). Various other aspects are also presented. These aspects have the benefit of responsive margin control when the overall packet error rate is relatively low, resulting in improved data throughput and increased system capacity.

Abstract: Methods and apparatus are presented for improving the feedback of channel information to a serving base station, which allows a reduction in the reverse link load while allowing the base station to improve the forward link data throughput. Over a channel quality indicator channel, three subchannels are generated; the re-synch subchannel, the differential feedback subchannel, and the transition indicator subchannel. The information carried on each subchannel can be used separately or together by a base station to selectively update internal registers storing channel conditions. The channel conditions are used to determine transmission formats, power levels, and data rates of forward link transmissions.

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.
