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 mobile station comprising:

a processor configured to;

receive a broadcast-to-pilot ratio from a base station;

determine a normalized data rate as a function of the received broadcast-to-pilot ratio and a power of a pilot signal received from the base station; and

a transmitter configured to transmit the normalized data rate to the base station.

2. The mobile station of claim 1, wherein the processor is further configured to receive a data rate indicator from the base station, the date rate indicator based on the transmitted normalized date rate.

3. The mobile station of claim 2, further comprising:

a receiver configured to receive traffic from the base station at a date rate indicated by the data rate indicator.

4. A mobile station comprising:

means for receiving a broadcast-to-pilot ratio from a base station;

means for determining a normalized data rate as a function of the received broadcast-to-pilot ratio and a power of a pilot signal received from the base station; and

means for transmitting the normalized data rate to the base station.

5. The mobile station of claim 4 further comprising:

means for receiving a data rate indicator from the base station, the date rate indicator based on the transmitted normalized date rate.

6. The mobile station of claim 5 further comprising:

means for receiving traffic from the base station at a date rate indicated by the data rate indicator.

7. A method of operating a mobile station comprising:

receiving a broadcast-to-pilot ratio from a base station;

determining, by said mobile station, a normalized data rate as a function of the received broadcast-to-pilot ratio and a power of a pilot signal received from the base station; and

transmitting, by said mobile station, the normalized data rate to the base station.

8. The method of claim 7 further comprising:

receiving a data rate indicator from the base station, the date rate indicator based on the transmitted normalized date rate.

9. The method of claim 8 further comprising:

receiving traffic from the base station at a date rate indicated by the data rate indicator.

10. A non-transitory processor-readable medium memory having instructions thereon executable by a processor, the instructions comprising:

code for receiving a broadcast-to-pilot ratio from a base station;

code for determining a normalized data rate as a function of the received broadcast-to-pilot ratio and a power of a pilot signal received from the base stations; and

code for transmitting the normalized data rate to the base station.

11. A non-transitory processor-readable medium memory of claim 10 further comprising:

code for receiving a data rate indicator from the base station, the date rate indicator based on the transmitted normalized date rate.

12. A non-transitory processor-readable medium memory of claim 10 further having comprising:

code for receiving traffic from the base station at a date rate indicated by the data rate indicator.
