Abstract

Included are embodiments for network allocation. More specifically, one embodiment of a method includes receiving, at a first communications device, without a prior RTS signal being sent, a first clear to send (CTS) signal from a second communications device, addressed to the first communications device, the CTS signal indicating a data exchange duration and sending a second CTS signal, from the first communications device, to the second communications device.

Claims (40)

1. A method, comprising:

receiving, at a first communications device, without a prior request to send (RTS) signal being sent, a first clear to send (CTS) signal from a second communications device, addressed to the first communications device, the CTS signal indicating a data exchange duration; and

sending a second CTS signal, from the first communications device, to the second communications device,

wherein a network allocation vector (NAV) is set by at least one other communications device, further comprising receiving, at the first communications device, a request to send (RTS) signal that directly follows the first CTS signal, the RTS signal directly following the first CTS signal is addressed to the first communications device, the RTS signal indicating a data exchange duration that does not exceed the data exchange duration of the first CTS signal.

2. The method of claim 1 , further comprising sending, by the second communications device, payload data to the first communications device.

3. The method of claim 1 , further comprising sending a third CTS signal from the first communications device to the second communications device, the third CTS signal being sent directly after the second CTS signal.

4. The method of claim 3 wherein the second CTS is configured at a first modulation and the third CTS is configured at a second modulation.

5. The method of claim 1 , wherein the NAV is configured to be non-resetting at the at least one other communications device.

6. The method of claim 1 , further comprising:

sending, by the second communications device, payload data to the first communications device, the NAV is configured to be non-resetting at the at least one other communications device.

7. The method of claim 1 , further comprising:

sending, by the second communications device, payload data to the first communications device;

sending a third CTS signal from the first communications device to the second communications device, the third CTS signal being sent directly after the second CTS signal, the second CTS is configured at a first modulation and the third CTS is configured at a second modulation, wherein the NAV is configured to be non-resetting at the at least one other communications device.

8. A non-transitory computer readable medium, comprising:

first receiving logic configured to receive, at a first communications device, without a prior request to send (RTS) signal being sent, a first clear to send (CTS) signal from a second communications device, addressed to the first communications device, the CTS signal indicating a data exchange duration; and

first sending logic configured to send a second CTS signal, from the first communications device, to the second communications device,

further comprising second receiving logic configured to receive, at the first communications device, a request to send (RTS) signal that directly follows the first CTS, the RTS directly following the first CTS signal is addressed to the first communications device, the RTS indicating a data exchange duration that does not exceed the data exchange duration of the first CTS.

9. The computer readable medium of claim 8 , further comprising third receiving logic configured to receive, by the first communications device payload data from the second communications device.

10. The computer readable medium of claim 8 , further comprising second sending logic configured to send a third CTS signal from the first communications device to the second communications device, the third CTS signal being sent directly after the second CTS signal.

11. The computer readable medium of claim 10 wherein the second CTS is configured at a first modulation and the third CTS is configured at a second modulation.

12. The computer readable medium of claim 8 , wherein the NAV is configured to be non-resetting at the at least one other communications device.

13. A system, comprising:

means for receiving, at a first communications device, without a prior request to send (RTS) signal being sent, a first clear to send (CTS) signal from a second communications device, addressed to the first communications device, the CTS signal indicating a data exchange duration; and

means for sending a second CTS signal, from the first communications device, to the second communications device,

wherein a network allocation vector (NAV) is set by at least one other communications device,

means for receiving, at the first communications device, a request to send (RTS) signal that directly follows the first CTS signal, the RTS directly following the first CTS signal is addressed to the first communications device, the RTX indicting a data exchange duration that does not exceed the data exchange duration of the first CTS.

14. The system of claim 13 , further comprising means for receiving, by the first communications device, payload data from the second communications device.

15. The system of claim 13 , further comprising means for sending a third CTS signal from the first communications device to the second communications device, the third CTS signal being sent directly after the second CTS signal.

16. The system of claim 15 , wherein the second CTS is configured at a first modulation and the third CTS is configured at a second modulation.

17. The system of claim 13 , further comprising:

means for receiving, by the first communications device, payload data from the second communications device; and

means for sending a third CTS signal from the first communications device to the second communications device, the third CTS signal being sent directly after the second CTS signal.

18. A method, comprising:

receiving, at a first communications device, without a prior request to send (RTS) signal being sent, a first clear to send (CTS) signal from a second communications device, addressed to the first communications device, the CTS signal indicating a data exchange duration;

sending a second CTS signal, from the first communications device, to the second communications device, and a network allocation vector (NAV) is set by at least one other communications device;

receiving, at the first communications device, a request to send (RTS) signal that directly follows the first CTS signal, the RTS signal directly following the first CTS signal is addressed to the first communications device, the RTS signal indicating a data exchange duration that does not exceed the data exchange duration of the first CTS signal;

sending, by the second communications device, payload data to the first communications device; and

sending a third CTS signal from the first communications device to the second communications device, the third CTS signal being sent directly after the second CTS signal.

19. The method of claim 18 wherein the second CTS is configured at a first modulation and the third CTS is configured at a second modulation.

20. The method of claim 18 , wherein the NAV is configured to be non-resetting at the at least one other communications device.
