System and method for medium access control enabling both full-duplex and half-duplex communications
Disclosed herein are systems, methods, and non-transitory computer-readable storage media for a modified MAC protocol which can facilitate communications with both full-duplex and half-duplex devices. A system configured according to the disclosed method can enable communications between an Access Point (AP) and a client in either full duplex or half duplex. The system can similarly enable peer-to-peer communications in both full duplex and half duplex communication modes.
1. A method comprising:
communicating first transmission data at a first rate on a common frequency spectrum, the first transmission data comprising part of data-to-be-communicated; and
upon receiving a received-data in the common frequency spectrum while communicating the first transmission data:
stopping communication of the first transmission data at a current frame;
dropping the current frame of the first transmission data;
initializing a second transmission data, the second transmission data comprising part of the data-to-be-communicated, a first frame of the second transmission data comprising a following frame which immediately follows the current frame of the first transmission data; and
communicating the second transmission data at a reduced rate on the common frequency spectrum.
2. The method of claim 1 , wherein the first transmission data is communicated in a first communication format and the received-data is received in a second communication format which is dissimilar to the first communication format.
3. The method of claim 2 , wherein the first communication format and the second communication format comprise full duplex communications and half duplex communications.
4. The method of claim 1 , wherein the first transmission data is communicated in a full duplex format and the received-data is received in the full duplex format.
5. The method of claim 1 , further comprising:
preparing self-interference cancellation while communicating the first transmission data; and
applying the self-interference cancellation only when receiving the received-data.
6. The method of claim 1 , wherein the current frame is not retransmitted after dropping the current frame.
7. The method of claim 1 , further comprising:
upon detecting a collision, stopping communication of the first transmission data and the second transmission data; and
communicating a jam signal.
8. The method of claim 7 , wherein communicating the jam signal is received by a plurality of full duplex clients.
9. A system, comprising:
a processor; and
a computer-readable storage device storing instructions which, when executed by
the processor, cause the processor to perform operations comprising:
communicating first transmission data at a first rate on a common frequency spectrum, the first transmission data comprising part of data-to-be-communicated; and
upon receiving a received-data in the common frequency spectrum while communicating the first transmission data:
stopping communication of the first transmission data at a current frame;
dropping the current frame of the first transmission data;
initializing a second transmission data, the second transmission data comprising part of the data-to-be-communicated, a first frame of the second transmission data comprising a following frame which immediately follows the current frame of the first transmission data; and
communicating the second transmission data at a reduced rate on the common frequency spectrum.
10. The system of claim 9 , wherein the first transmission data is communicated in a first communication format and the received-data is received in a second communication format which is dissimilar to the first communication format.
11. The system of claim 10 , wherein the first communication format and the second communication format comprise full duplex communications and half duplex communications.
12. The system of claim 9 , wherein the first transmission data is communicated in a full duplex format and the received-data is received in the full duplex format.
13. The system of claim 9 , the computer-readable storage device storing additional instructions which, when executed by the processor, cause the processor to perform operations comprising:
preparing self-interference cancellation while communicating the first transmission data; and
applying the self-interference cancellation only when receiving the received-data.
14. The system of claim 9 , wherein the current frame is not retransmitted after dropping the current frame.
15. The system of claim 9 , the computer-readable storage device storing additional instructions which, when executed by the processor, cause the processor to perform operations comprising:
upon detecting a collision, stopping communication of the first transmission data and the second transmission data; and
communicating a jam signal.
16. The system of claim 15 , wherein communicating the jam signal is received by a plurality of full duplex clients.
17. A computer-readable storage device storing instructions which, when executed on a processor, cause the processor to perform operations comprising:
communicating first transmission data at a first rate on a common frequency spectrum, the first transmission data comprising part of data-to-be-communicated; and
upon receiving a received-data in the common frequency spectrum while communicating the first transmission data:
stopping communication of the first transmission data at a current frame;
dropping the current frame of the first transmission data;
initializing a second transmission data, the second transmission data comprising part of the data-to-be-communicated, a first frame of the second transmission data comprising a following frame which immediately follows the current frame of the first transmission data; and
communicating the second transmission data at a reduced rate on the common frequency spectrum.
18. The computer-readable storage device of claim 17 , wherein the first transmission data is communicated in a first communication format and the received-data is received in a second communication format which is dissimilar to the first communication format.
19. The computer-readable storage device of claim 18 , wherein the first communication format and the second communication format comprise full duplex communications and half duplex communications.
20. The computer-readable storage device of claim 17 , wherein the first transmission data is communicated in a full duplex format and the received-data is received in the full duplex format.
