    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: 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.

    Abstract: 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.
