Abstract

A communication device receives control information during transmission of streaming data, such as speech data, over a wireless channel (300). The communication device identifies a portion of the streaming data, such as representing a pause in speech, as compressible data or white space data (310, 320). Continuous transmission of the streaming data is interrupted to request and receive control information on the wireless channel, using the channel space made available by not transmitting the identified portion of data or by transmitting it in a more compressed format (330, 340).

Claims

1. In a radio communication system, a method for obtaining control information during a communication session, the method comprising the steps of:

obtaining streaming data for transmission over a frequency division multiple access (FDMA) wireless communication channel;

transmitting the streaming data over the FDMA wireless communication channel in a continuous manner using a particular format;

interrupting continuous transmission of the streaming data to receive control information, including the steps of;

identifying a portion of the streaming data not required to be transmitted in the particular format; and

requesting and receiving power control information via the FDMA wireless communication channel using channel space thereon made available by not transmitting the portion of the streaming data in the particular format.

2. The method of claim 1, wherein the streaming data comprises speech data, and the step of identifying comprises the step of detecting a pause in speech in the speech data.

3. The method of claim 1, further comprising the step of converting the portion of the streaming data to another format more compressed than the particular format.

4. A method, comprising the steps of:

initiating a transmission session to transmit speech data over a wireless communication channel in a particular format;

detecting white space data within the speech data, wherein the white space comprises a pause in speech in the speech data;

interrupting the transmission session to receive information including the steps of;

suppressing transmission of the white space data in the particular format for a particular time period; and

requesting and receiving a short burst message over the wireless communication channel during the particular time period.

5. The method of claim 4, wherein the short burst message comprises power control information.

6. The method of claim 4, further comprising the step of transmitting the speech data using a frequency division multiple access communication protocol.

7. A method for obtaining power control information during a communication session between a first communication device and a second communication device in a radio frequency communication system, the method comprising the steps of:

at the first communication device;

obtaining streaming speech data for transmission;

transmitting the streaming speech data over a frequency division multiple access channel to the second communication device, including the steps of;

identifying a portion of the streaming speech data representing a pause in speech;

when the pause in speech has a duration exceeding a particular threshold;

interrupting transmission of the streaming speech data;

transmitting a power control request to the second communication device; and

receiving power control information from the second communication device.

8. The method of claim 7, further comprising the steps of resuming transmission of the streaming speech data power level based on the power control information received.

9. The method of claim 7, further comprising the steps of:

at the second communication device;

receiving a request for power control information from the first communication device during receipt of streaming speech data;

transmitting power control information in response to the request; and

outputting comfort noise as a substitute for expected pause in speech data.
