    Abstract: A method and apparatus for scheduling transmit rates and power levels for data in conjunction with a voice-data communication during conditions of soft and softer handoff. During conditions of no handoff, or hard handoff, an algorithm selects a slot reflecting a favored power level and transmission rate for transmitting the non-voice data on a supplemental channel. The slot is selected based upon the transmission power levels for voice-data transmitted by a base station to a remote station on a fundamental channel. The algorithm applies to softer handoff using information from all the sectors of a base station involved in the softer handoff. During soft handoff, instead of scheduling forward link transmission based on recent power and rate, or C/I information, data is continuously transmitted to the user at a power level based on average required power.

    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: Systems and techniques are disclosed relating to communications. The systems and techniques involve transmitting a signal over a plurality of time periods, receiving a plurality of parameters each relating to the signal transmission during a different one of the time periods, filtering a first one of the parameters to generate a first filtered parameter, filtering a second one of the parameters as a function of the first filtered parameter to generate a second filtered parameter, and adjusting the signal as a function of the second filtered parameter.

    Abstract: An apparatus operative to transmit packet data via at least one of a first set of channels in a wireless communications system, the system supporting packet data transmissions and low delay data transmissions over a plurality of transmission channels. The apparatus comprising means for transmitting packet data via a set of packet data channels; means for transmitting control information associated with the packet data via a signalling channel, wherein the signalling channel is separate from the set of packet data channels, and wherein the control information identifies a target recipient of associated packet data; means for receiving data requests from a plurality of mobile units; means for determining a transmission schedule according to the data requests; means for assigning a priority level to each of the plurality of mobile units; and means for determining a traffic schedule among the plurality of mobile units based on the assigned priority level.
