Abstract

Techniques are described for wireless communication. A first method includes contending for access to a first channel of a radio frequency spectrum, and transmitting, upon winning contention for access to the first channel, a first channel reservation indication. The contending may be performed by a first node operating according to a first radio access technology. The first channel reservation indication may be understood by a second node operating according to a second radio access technology.

Claims (58)

1. A method of wireless communication, comprising:

receiving, from a first node associated with a first radio access technology at second node operating according to a second radio access technology, a first channel reservation indication and at least one of a channel usage beacon signal (CUBS) or a fractional CUBS (F-CUBS), the first channel reservation indication and the at least one of the CUBS or the F-CUBS decodable by the second node utilizing the second radio access technology;

wherein receiving the first channel reservation indication occurs during one of: before receiving the CUBS; after receiving the CUBS; before receiving the F-CUBS and the CUBS; after receiving the F-CUBS and before receiving the CUBS; or after receiving the F-CUBS and the CUBS.

2. The method of claim 1 , wherein receiving the first channel reservation indication comprises:

receiving the first channel reservation indication on at least a first channel of a radio frequency spectrum.

3. The method of claim 1 , wherein receiving the first channel reservation indication comprises:

receiving the first channel reservation indication on at least a second channel of a radio frequency spectrum.

4. The method of claim 3 , wherein receiving the first channel reservation indication on at least the second channel comprises:

receiving the first channel reservation indication on a plurality of channels.

5. The method of claim 1 , wherein receiving the first channel reservation indication comprises:

receiving the first channel reservation indication on a primary channel of the second node.

6. The method of claim 1 , wherein receiving the first channel reservation indication comprises:

receiving the first channel reservation indication on at least one channel of the radio frequency spectrum, the first channel reservation indication indicating at least one other channel occupied by the first radio access technology.

7. The method of claim 1 , further comprising:

receiving instructions to transmit the first channel reservation indication over at least one of a first channel or a second channel of a radio frequency spectrum.

8. The method of claim 7 , wherein the instructions are received in at least one of an uplink grant or a radio resource control (RRC) signaling message.

9. The method of claim 1 , wherein the first channel reservation indication comprises a Wi-Fi preamble or Wi-Fi packet.

10. The method of claim 1 , wherein the first channel reservation indication is associated with reserving at least a first channel of a radio frequency spectrum for a period of time, the method further comprising:

receiving a second channel reservation indication, separated in time from the first channel reservation indication, to extend a reservation of the first channel by the first node.

11. The method of claim 1 , wherein the first channel reservation indication is based at least in part on either a relative timing of a subframe boundary or symbol period boundary with respect to winning contention for access to a first channel of a radio frequency spectrum, or an intended channel occupancy after winning contention for access to the first channel.

12. An apparatus for wireless communication, comprising:

a processor;

memory in electronic communication with the processor; and

instructions stored in the memory, the instructions being executable by the processor to:

receive, from a first node associated with a first radio access technology at second node operating according to a second radio access technology, a first channel reservation indication and at least one of a channel usage beacon signal (CUBS) or a fractional CUBS (F-CUBS), the first channel reservation indication and the at least one of the CUBS or the F-CUBS decodable by the second node utilizing the second radio access technology;

wherein receiving the first channel reservation indication occurs during one of: before receiving the CUBS; after receiving the CUBS; before receiving the F-CUB S and the CUBS; after receiving the F-CUBS and before receiving the CUBS; or after receiving the F-CUBS and the CUBS.

13. The apparatus of claim 12 , wherein the instructions executable to receive the first channel reservation indication comprise instructions executable by the processor to:

receive the first channel reservation indication on at least a first channel or a second channel of a radio frequency spectrum.

14. The apparatus of claim 12 , wherein the instructions executable to receive the first channel reservation indication comprise instructions executable by the processor to:

receive the first channel reservation indication on a plurality of channels.

15. The apparatus of claim 12 , wherein the instructions executable to receive the first channel reservation indication comprise instructions executable by the processor to:

receive the first channel reservation indication on at least one channel of the radio frequency spectrum, the first channel reservation indication indicating at least one other channel occupied by the first radio access technology.

16. The apparatus of claim 12 , wherein the instructions are executable by the processor to:

receive instructions to transmit the first channel reservation indication over at least one of a first channel or a second channel of a radio frequency spectrum.

17. The apparatus of claim 16 , wherein the instructions are received in at least one of an uplink grant or a radio resource control (RRC) signaling message.

18. The apparatus of claim 12 , wherein the first channel reservation indication comprises a Wi-Fi preamble or Wi-Fi packet.

19. The apparatus of claim 12 , wherein the first channel reservation indication is associated with reserving at least a first channel of a radio frequency spectrum for a period of time, the instructions further executable by the processor to:

receive a second channel reservation indication, separated in time from the first channel reservation indication, to extend a reservation of the first channel by the first node.

20. The apparatus of claim 12 , wherein the first channel reservation indication is based at least in part on either a relative timing of a subframe boundary or symbol period boundary with respect to winning contention for access to a first channel of a radio frequency spectrum, or an intended channel occupancy after winning contention for access to the first channel.

21. An apparatus for wireless communication, comprising:

means for receiving, from a first node associated with a first radio access technology at second node operating according to a second radio access technology, a first channel reservation indication and at least one of a channel usage beacon signal (CUBS) or a fractional CUBS (F-CUBS), the first channel reservation indication and the at least one of the CUBS or the F-CUBS decodable by the second node utilizing the second radio access technology;

wherein the means for receiving the first channel reservation indication occurs during one of: before receiving the CUBS; after receiving the CUBS; before receiving the F-CUBS and the CUBS; after receiving the F-CUBS and before receiving the CUBS; or after receiving the F-CUBS and the CUBS.

22. The apparatus of claim 21 , wherein the means for receiving the first channel reservation indication comprises:

means for receiving the first channel reservation indication on at least a first channel or a second channel of a radio frequency spectrum.

23. The apparatus of claim 21 , wherein the means for receiving the first channel reservation indication comprises:

means for receiving the first channel reservation indication on a plurality of channels.

24. The apparatus of claim 21 , wherein the means for receiving the first channel reservation indication comprises:
