Abstract

Certain aspects of the present disclosure generally relate to methods and apparatus for performing channel usage indication in a wireless communication environment. A transmitting apparatus may be configured to determine a residual length of an ongoing transmission burst including a plurality of segments. The transmitting apparatus may transmit, in at least one segment of the transmission burst, control information indicating the residual length of the ongoing transmission burst. A receiving apparatus may be configured to monitor a segment of the ongoing transmission burst, and to determine the residual length of the transmission burst, based on control information transmitted in the monitored segment.

Claims

1. A method for wireless communication by an apparatus, comprising:

monitoring a segment of an ongoing transmission burst comprising a plurality of segments; and

determining a residual length of the ongoing transmission burst, based on control information transmitted in the monitored segment.

2. The method of claim 1, wherein the control information transmitted in the monitored segment indicates the residual length as a number of segments remaining in the transmission burst.

3. The method of claim 1, wherein:

the control information is transmitted periodically but not in each segment; and

monitoring the segment comprises monitoring a segment in which the control information is transmitted.

4. The method of claim 1, wherein a segment comprises a minimum time-unit over which a waveform of the transmission burst is transmitted.

5. The method of claim 1, further comprising:

power down one or more radio components during the residual length of the transmission burst.

6. The method of claim 1, further comprising:

communicating at a reduced spectral efficiency, relative to a spectral efficiency of communications between transmission bursts, during the residual length of the transmission burst.

7. The method of claim 1, wherein the control information included in the monitored segment comprises a counter indicating the remaining number of segments of the interfering transmission burst, the counter decremented each successive segment of a transmission burst.

8. The method of claim 1, comprising:

monitoring only one segment in a transmission burst; and

powering down one or more radio components for remaining segments of the transmission burst.

9. The method of claim 1, further comprising:

monitoring a last segment of the transmission burst; and

determining a duration between transmission bursts, based on control information included in the last segment.

10. The method of claim 9, wherein the control information included in the last segment indicates the duration between transmission bursts as a number of segments between transmission bursts.

11. The method of claim 9, further comprising:

communicating at an increased spectral efficiency, relative to a spectral efficiency of communications during transmission bursts, during one or more of the segments between transmission bursts.

12. The method of claim 1, further comprising:

determining a priority of the ongoing transmission burst, based on control information transmitted in the monitored segment.

13. An apparatus for wireless communication, comprising:

means for monitoring a segment of an ongoing transmission burst comprising a plurality of segments; and

means for determining a residual length of the ongoing transmission burst, based on control information transmitted in the monitored segment

14. A computer-readable medium comprising code executable by one or more processors for:

monitoring a segment of an ongoing transmission burst comprising a plurality of segments; and

determining a residual length of the ongoing transmission burst, based on control information transmitted in the monitored segment.

15. A method for wireless communication by an apparatus, comprising:

determining a residual length of an ongoing transmission burst comprising a plurality of segments; and

transmitting, in at least one segment of the transmission burst, control information indicating the residual length of the ongoing transmission burst.

16. The method of claim 15, wherein the control information transmitted in the at least one segment indicates the residual length of the transmission burst as a number of segments remaining in the transmission burst.

17. The method of claim 15, wherein:

the control information is transmitted periodically, but not in each segment.

18. The method of claim 15, wherein a segment comprises a minimum time-unit over which a waveform of the transmission burst is transmitted.

19. The method of claim 15, wherein control information indicating the residual length of the transmission burst is transmitted in each segment of the transmission burst.

20. The method of claim 19, wherein the control information indicating the residual length of the transmission burst comprises a counter indicating the remaining number of segments of the interfering transmission burst, the counter decremented each successive segment of the transmission burst.

21. The method of claim 15, further comprising:

determining a duration between transmission bursts; and

transmitting, in a last segment of the transmission burst, control information indicating the duration before a start of a next transmission burst.

22. The method of claim 21, wherein the control information transmitted in the last segment indicates the duration before the start of the next transmission burst as a number of segments between transmission bursts.

23. The method of claim 15, further comprising:

transmitting, in the at least one segment of the ongoing transmission burst, a priority of the ongoing transmission burst.

24. An apparatus for wireless communication, comprising:

means for determining a residual length of an ongoing transmission burst comprising a plurality of segments; and

means for transmitting, in at least one segment of the transmission burst, control information indicating the residual length of the ongoing transmission burst.
