CLAIMS

WHAT IS CLAIMED IS:

1. A method of wireless communication by a transmitter, the method comprising: sending a first transmission packet, the first transmission packet including first data encoded with a first bitrate;

sending a second transmission packet, the second transmission packet including second data encoded with the first bitrate; and

sending a first retransmission packet after sending the first transmission packet and the second transmission packet, the first retransmission packet including the first data encoded with a second bitrate and the second data encoded with the second bitrate, wherein the first bitrate is higher than the second bitrate.

2. The method of claim 1 , wherein the first data includes at least one of audio data or video data.

3. The method of claim 2, wherein the first data comprises an audio frame associated with a duration, the duration being equal when the first data is encoded with the first bitrate and when the first data is encoded with the second bitrate.

4. The method of claim 1, wherein the first transmission packet, the second transmission packet, and the first retransmission packet are sent as broadcast.

5. The method of claim 1 , wherein the first retransmission packet indicates that the first data encoded with the second bitrate corresponds to the first data encoded with the first bitrate included in the first transmission packet, and wherein the first retransmission packet further indicates that the second data encoded with the second bitrate corresponds to the second data encoded with the first bitrate included in the second transmission packet.

6. The method of claim 1 , further comprising:

sending a second retransmission packet after sending the first retransmission packet, the second retransmission packet including the first data encoded with a third bitrate and the second data encoded with the third bitrate.

7. The method of claim 6, wherein the third bitrate is equal to the second bitrate or the third bitrate is lower than the second bitrate.

8. The method of claim 1 , further comprising:

encoding, by a first digital signal processor (DSP), the first data with the first bitrate for inclusion in the first transmission packet and the second data with the first bitrate for inclusion in the second transmission packet; and

encoding, by a second DSP, the first data with the second bitrate for inclusion in the first retransmission packet.

9. A method of wireless communication by a receiver, the method comprising: receiving a first transmission packet, the first transmission packet including first data encoded with a first bitrate;

receiving a first retransmission packet after receiving the first transmission packet, the first retransmission packet including second data encoded with a second bitrate, wherein the first bitrate is higher than the second bitrate;

determining that the second data encoded with the first bitrate is unavailable to be output; and

outputting the second data encoded with the second bitrate based on the determination that the second data encoded with the first bitrate is unavailable to be output.

10. The method of claim 9, wherein the first data and the second data include at least one of audio data or video data.

1 1. The method of claim 9, further comprising:

outputting the first data encoded with the first bitrate,

wherein the output of the first data is higher quality than the output of the second data based on the first bitrate being higher than the second bitrate.

12. The method of claim 1 1, further comprising:

controlling gain associated with the output of the second data to correspond with the output of the first data.

13. The method of claim 1 1, further comprising:

determining that the second data encoded with the second bitrate is to be output after the output of the first data based on an indication associated with the first retransmission packet indicating that the second data sequentially follows the first data.

14. The method of claim 1 1, wherein the first retransmission packet further includes the first data encoded with the second bitrate.

15. The method of claim 9, wherein the first transmission packet and the first retransmission packet are received as broadcast, and wherein the reception of the first transmission packet and the reception of the first retransmission packet are unacknowledged by the receiver.

16. The method of claim 9, wherein the determining that the second data encoded with the first bitrate is unavailable to be output comprises:

determining that a second transmission packet is unreceived, the second transmission packet being expected to include the second data encoded with the first bitrate.

17. The method of claim 9, wherein the determining that the second data encoded with the first bitrate is unavailable to be output comprises:

determining that a second transmission packet including the second data encoded with the first bitrate is corrupted or the second data encoded with the first bitrate is corrupted.

18. A transmitter comprising:

means for sending a first transmission packet, the first transmission packet including first data encoded with a first bitrate;

means for sending a second transmission packet, the second transmission packet including second data encoded with the first bitrate; and

means for sending a first retransmission packet after sending the first transmission packet and the second transmission packet, the first retransmission packet including the first data encoded with a second bitrate and the second data encoded with the second bitrate,

wherein the first bitrate is higher than the second bitrate.

19. The transmitter of claim 18, wherein the first data includes at least one of audio data or video data.

20. The transmitter of claim 19, wherein the first data comprises an audio frame associated with a duration, the duration being equal when the first data is encoded with the first bitrate and when the first data is encoded with the second bitrate.

21. The transmitter of claim 18, wherein the first transmission packet, the second transmission packet, and the first retransmission packet are sent as broadcast.

22. The transmitter of claim 18, wherein the first retransmission packet indicates that the first data encoded with the second bitrate corresponds to the first data encoded with the first bitrate included in the first transmission packet, and wherein the first retransmission packet further indicates that the second data encoded with the second bitrate corresponds to the second data encoded with the first bitrate included in the second transmission packet.

23. The transmitter of claim 18, further comprising:

means for sending a second retransmission packet after sending the first retransmission packet, the second retransmission packet including the first data encoded with a third bitrate and the second data encoded with the third bitrate.

24. The transmitter of claim 23, wherein the third bitrate is equal to the second bitrate or the third bitrate is lower than the second bitrate.

25. The transmitter of claim 18, further comprising:

means for encoding, by a first digital signal processor (DSP), the first data with the first bitrate for inclusion in the first transmission packet and the second data with the first bitrate for inclusion in the second transmission packet; and

means for encoding, by a second DSP, the first data with the second bitrate for inclusion in the first retransmission packet.

26. A receiver comprising:

means for receiving a first transmission packet, the first transmission packet including first data encoded with a first bitrate;

means receiving a first retransmission packet after receiving the first transmission packet, the first retransmission packet including second data encoded with a second bitrate, wherein the first bitrate is higher than the second bitrate;

means for determining that the second data encoded with the first bitrate is unavailable to be output; and

means for outputting the second data encoded with the second bitrate based on the determination that the second data encoded with the first bitrate is unavailable to be output.

27. The receiver of claim 26, wherein the first data and the second data include at least one of audio data or video data.

28. The receiver of claim 26, further comprising:

means for outputting the first data encoded with the first bitrate,

wherein the output of the first data is higher quality than the output of the second data based on the first bitrate being higher than the second bitrate.

29. The receiver of claim 28, further comprising:

means for controlling gain associated with the output of the second data to correspond with the output of the first data.
