摘要： 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.

摘要： In a wireless communication system (50) a method for combination transmission of packet data and low delay data. In one embodiment a parallel signaling channel provides a message to receivers (56, 58, 60) indicating a target recipient of packet data. The message also identifies the transmission channel used for packet data transmissions. Each receiver may then selectively decode only packets where the message identifies the receiver as a target recipient. The data packets stored in a buffer are ignored if the target recipient is another mobile unit. In one embodiment, the message is sent concurrently with the data packet on a parallel channel. In one embodiment, the message is punctured into the high rate packet data transmission.

摘要： 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.
