Abstract

Systems, methods, and devices for transmitting data are described herein. In some aspects, a method comprises generating a first message. The first message may comprise an allocation of a first station to a first frequency channel and a second station to a second frequency channel. The method further comprises transmitting the first message over the first frequency channel and the second frequency channel. The method further comprises transmitting, after transmission of the first message, a second message to the first station using the first frequency channel. The method further comprises transmitting, after transmission of the first message, a third message to the second station using the second frequency channel.

Claims (35)

1. A method for transmitting data, comprising:

transmitting a request to send message to a first station and a second station, the request to send message comprising a first time allocated for the first station to send a first clear to send message and a second time allocated for the second station to send a second clear to send message;

receiving at least one of the first clear to send message from the first station or the second clear to send message from the second station;

transmitting, in response to reception of the first clear to send message from the first station over a primary frequency channel, a first data packet to the first station over the primary frequency channel; and

transmitting, in response to reception of the second clear to send message from the second station over a secondary frequency channel, a second data packet to the second station over the secondary frequency channel.

2. The method of claim 1 , wherein transmitting the request to send message comprises transmitting the request to send message to the first station over the primary frequency channel and to the second station over the secondary frequency channel.

3. The method of claim 1 , wherein transmitting the request to send message comprises transmitting the request to send message to the first station and the second station over the primary frequency channel.

4. The method of claim 3 , wherein transmitting the request to send message comprises transmitting a first instruction specifying the first station to transmit the first clear to send message over the primary frequency channel and a second instruction specifying the second station to transmit the second clear to send message over the secondary frequency channel.

5. The method of claim 1 , the first time and the second time being a same time.

6. The method of claim 1 , the first clear to send message from the first station being received according to the first time and the second clear to send message from the second station is received according to the second time.

7. An apparatus for transmitting data, comprising:

means for transmitting a request to send message to a first station and a second station, the request to send message comprising a first time allocated for the first station to send a first clear to send message and a second time allocated for the second station to send a second clear to send message;

means for receiving at least one of the first clear to send message from the first station or the second clear to send message from the second station;

means for transmitting, in response to reception of the first clear to send message from the first station over a primary frequency channel, a first data packet to the first station over the primary frequency channel; and

means for transmitting, in response to reception of the second clear to send message from the second station over a secondary frequency channel, a second data packet to the second station over the secondary frequency channel.

8. The apparatus of claim 7 , wherein means for transmitting the request to send message comprises means for transmitting the request to send message to the first station over the primary frequency channel and to the second station over the secondary frequency channel.

9. The apparatus of claim 7 , wherein means for transmitting the request to send message comprises means for transmitting the request to send message to the first station and the second station over the primary frequency channel.

10. The apparatus of claim 9 , wherein means for transmitting the request to send message comprises means for transmitting a first instruction specifying the first station to transmit the first clear to send message over the primary frequency channel and a second instruction specifying the second station to transmit the second clear to send message over the secondary frequency channel.

11. The apparatus of claim 7 , wherein the means for transmitting the request to send message, the means for transmitting the first data packet, and the means for transmitting the second data packet comprise a transmitter, and the means for receiving comprising a receiver.

12. A non-transitory computer-readable medium comprising code that, when executed, causes an apparatus to:

transmit a request to send message to a first station and a second station, the request to send message comprising a first time allocated for the first station to send a first clear to send message and a second time allocated for the second station to send a second clear to send message;

receive at least one of the first clear to send message from the first station or the second clear to send message from the second station;

transmit, in response to reception of the first clear to send message from the first station over a primary frequency channel, a first data packet to the first station over the primary frequency channel; and

transmit, in response to reception of the second clear to send message from the second station over a secondary frequency channel, a second data packet to the second station over the secondary frequency channel.

13. The medium of claim 12 , further comprising code that, when executed, causes an apparatus to transmit the request to send message to the first station over the primary frequency channel and to the second station over the secondary frequency channel.

14. The medium of claim 12 , further comprising code that, when executed, causes an apparatus to transmit the request to send message to the first station and the second station over the primary frequency channel.

15. The medium of claim 14 , further comprising code that, when executed, causes an apparatus to transmit a first instruction specifying the first station to transmit the first clear to send message over the primary frequency channel and a second instruction specifying the second station to transmit the second clear to send message over the secondary frequency channel.

16. An apparatus for transmitting data, comprising:

a transmitter configured to transmit a request to send message to a first station and a second station, the request to send message comprising a first time allocated for the first station to send a first clear to send message and a second time allocated for the second station to send a second clear to send message; and

a receiver configured to receive at least one of the first clear to send message from the first station or the second clear to send message from the second station, the transmitter further configured to transmit, in response to reception of the first clear to send message from the first station over a primary frequency channel, a first data packet to the first station over the primary frequency channel, and the transmitter further configured to transmit, in response to reception of the second clear to send message from the second station over a secondary frequency channel, a second data packet to the second station over the secondary frequency channel.

17. The apparatus of claim 16 , the transmitter further configured to transmit the request to send message to the first station over the primary frequency channel and to the second station over the secondary frequency channel.

18. The apparatus of claim 16 , the transmitter further configured to transmit the request to send message to the first station and the second station over the primary frequency channel.

19. The apparatus of claim 18 , the transmitter further configured to transmit a first instruction specifying the first station to transmit the first clear to send message over the primary frequency channel and a second instruction specifying the second station to transmit the second clear to send message over the secondary frequency channel.

20. The apparatus of claim 16 , the first time and the second time being a same time.

21. The apparatus of claim 16 , the first clear to send message from the first station being received according to the first time and the second clear to send message from the second station is received according to the second time.
