Abstract: A method and apparatus for selecting a favored transmission slot for communicating non-voice data in conjunction with a voice-data communication. The slot, reflecting a favored power level and transmission rate for transmitting the non-voice data on a supplemental channel, 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 favored transmission slot is selected without the remote station messaging information to the base station concerning frequency channel or interference information for the supplemental channel. A method of performing forward-link scheduling in a wireless communication system includes determining the available base station power at the beginning of a frame, predicting the required transmit power at the beginning of the frame for each supplemental channel, determining rates sustainable with the predicted transmit power, dividing by throughput over a recent window to obtain a supplemental channel priority index, and allowing the supplemental channel with the highest priority index to transmit over the next frame.

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: A method for formatting a packet into a transmission format comprising: determining a fading curve representative of a transmission channel on which the packet is to be sent to a remote station; determining a margin offset to the fading curve based on a feedback message from the remote station; and determining whether a transmission format incorporating the margin offset is feasible for formatting the packet; and if feasible, then formatting the packet according the trasmission format incorporating the margin offset.

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 one or more specific sizes 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 a value of common TPR commands received from the base station. A fast-ramp-up behavior for adjustments of the authorized-TPR is followed when the authorized-TPR is less than the target-TPR. The down TPR commands are ignored in the adjustments of the authorized-TPR to allow following a fast-ramp-up behavior.

Abstract: A method for scheduling packet data transmissions in a wireless communication system wherein a per-user Priority Function (PF) is calculated based on the channel condition and throughput for each user. In one embodiment, the system supports retransmission of data packets and sub-packets, wherein the retransmission information is used to schedule data transmissions. In another embodiment, at each time interval the system updates the priority factor for the user having the highest priority factor in the previous time interval. The priority factors of the other users remain unchanged.
