Abstract

In a wireless communication system a method for combination transmission of packet data and low delay data. In one embodiment a parallel signaling channel provides a message to receivers indicating a target recipient of packet data. The message also identifies the transmission channels 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.

Claims

1. A wireless apparatus operative to receive packet data via at least one of a first set of channels, the wireless apparatus comprising:

a processor operative to receive messages via a signaling channel and to determine target recipient information and coding information from a received message identifying a target recipient, the target recipient being at least one of a plurality of recipients, the signaling channel being separate from the first set of channels;

a data rate determination unit operative to calculate a data rate for receiving packet data over the at least one of the first set of channels in accordance with the target recipient information and the coding information, and in accordance with a calculation based on a received pilot signal, the calculation based on the received pilot signal comprising a signal-to-noise ratio calculated by the wireless apparatus; and

a transmitter operative to send the calculated data rate to a transmitting base station as a data request,

wherein the target recipient information comprises a broadcast-to-pilot ratio indicative of a total transmit power as compared to a power consumed for transmission of the received pilot signal.

2. The wireless apparatus of claim 1, further comprising:

a buffer coupled to the processor, the buffer operative to store packet data received via the at least one of the first set of channels; and

a decoder coupled to the processor, the decoder operative to decode data packets received if the wireless apparatus is the target recipient identified by the received message and ignore data packets if the wireless apparatus is not the target recipient.

3. The wireless apparatus of claim 1, wherein the target recipient information identifies multiple target recipients.

4. The wireless apparatus of claim 1, wherein the wireless apparatus is a mobile user terminal that is the target recipient and the received message originates from a transmitting station.

8. The wireless apparatus of claim 1, wherein the coding information is predetermined by the transmitter and is used to encode the packet data, and wherein the wireless apparatus further comprises:

a decoder coupled to the processor, the decoder responsive to the coding information to decode received packet data.

9. A wireless apparatus operative to receive packet data via at least one of a first set of channels, the wireless apparatus comprising:

means for receiving messages via a signaling channel and to determine target recipient information and coding information from a received message identifying a target recipient, the target recipient being at least one of a plurality of recipients, the signaling channel being separate from the first set of channels;

means for calculating a data rate for receiving packet data over the at least one of the first set of channels in accordance with the target recipient information and the coding information, and in accordance with a calculation based on a received pilot signal, the calculation based on the received pilot signal comprising a signal-to-noise ratio calculated by the wireless apparatus; and

means for sending the calculated data rate to a transmitting base station as a data request,

wherein the target recipient information comprises a broadcast-to-pilot ratio indicative of a total transmit power as compared to a power consumed for transmission of the received pilot signal.

10. The wireless apparatus of claim 9, further comprising:

means for storing packet data received via the at least one of the first set of channels; and

means for decoding data packets received if the wireless apparatus is the target recipient identified by the received message and ignore data packets if the wireless apparatus is not the target recipient.
