Abstract

A method performed under control of a first device capable of full duplex radio communications may include receiving a first part of a first data from a second device capable of the full duplex radio communications; determining that the second device has transmitted the first data to the first device, based, at least in part, on the received first part of the first data; and transmitting a second data to the second device, while receiving a second part of the first data from the second device.

Claims

1. A method performed under control of a first device capable of full duplex radio communication, the method comprising:

receiving a first part of first data from a second device capable of the full duplex radio communication, wherein the first part of the first data includes a checksum for the first part of the first data;

decoding the first part of the first data;

validating the decoded first part of the first data, based, at least in part, on the checksum for the first part of the first data, wherein the first part of the first data includes a packet header;

determining that the second device has transmitted the first data to the first device, based, at least in part, on the validated first part of the first data;

generating second data, with a length shorter than a length of the first data based, at least in part, on the packet header of the first data; and

in response to the determination that the second device has transmitted the first data to the first device, transmitting the second data to the second device, while receiving a second part of the first data from the second device.

2. The method of claim 1, wherein the second part of the first data includes a packet body.

3. The method of claim 2,

wherein:

the decoding the first part of the first data includes decoding the packet header of the first data, and

the determining is based on the decoded packet header of the first data.

4. The method of claim 2, wherein the packet header of the first data includes information regarding an origin of the first data and a destination of the first data.

5. The method of claim 2, wherein the packet header of the first data includes information regarding the length of the first data.

6. The method of claim 5, wherein the length of the second data is equal to a length of the packet body of the first data.

7. The method of claim 1, wherein the first part of the first data includes a first orthogonal frequency division multiplexing (OFDM) frame, and wherein the second part of the first data includes a second OFDM frame.

8. The method of claim 7, wherein the first OFDM frame has null data, and wherein the first OFDM frame includes information regarding an origin of the first data and a destination of the first data.

9. A first device capable of full duplex radio communication, the first device comprising:

a receiver configured to receive a first part of a first data from a second device capable of the full duplex radio communication, wherein the first part of the first data includes a checksum for the first part of the first data, and wherein the first part of the first data includes a packet header;

a decoder coupled to the receiver and configured to;

decode the first part of the first data, and

validate the decoded first part of the first data, based, at least in part, on the checksum for the first part of the first data;

a data manager, coupled to the decoder, configured to;

generate second data, with a length shorter than a length of the first data, based, at least in part, on the packet header of the first data; and

determine that the second device has transmitted the first data to the first device, based, at least in part, on the validated first part of the first data; and

a transmitter coupled to the data manager and configured to, in response to the determination by the data manager that the second device has transmitted the first data to the first device, transmit the second data to the second device, while the receiver receives a second part of the first data from the second device.

10. The first device of claim 9, wherein the second part of the first data includes a packet body.

11. The first device of claim 10,

wherein:

the decoder is configured to decode the packet header of the first data, and

the data manager is configured to determine that the second device has transmitted the first data to the first device, based on the decoded packet header of the first data.

12. The first device of claim 10, wherein the packet header of the first data includes information regarding an origin of the first data and a destination of the first data.

13. The first device of claim 10, wherein the packet header of the first data includes information regarding the length of the first data.

14. The first device of claim 13, wherein the length of the second data is equal to a length of the packet body of the first data.

15. The first device of claim 9, wherein the first part of the first data includes a first orthogonal frequency division multiplexing (OFDM) frame, and wherein the second part of the first data includes a second OFDM frame.

16. The first device of claim 15, wherein the first OFDM frame includes null data, and wherein the first OFDM frame includes information regarding an origin of the first data and a destination of the first data.

17. A non-transitory computer-readable storage medium having stored thereon computer-executable instructions that, in response to execution, cause a first device capable of full duplex radio communication to perform or control performance of operations, comprising:

identify a header part, of a first packet, received from a second device capable of the full duplex radio communication, wherein the header part of the first packet includes information regarding a length of the first packet;

decode the header part of the first packet;

determine that the second device has transmitted the first packet to the first device, based, at least in part, on the decoded header part of the first packet;

in response to the determination that the second device has transmitted the first packet to the first device, generate a second packet that has a length shorter than the length of the first packet, based, at least in part, on the decoded header part of the first packet; and

transmit the second packet to the second device, while a body part of the first packet is received from the second device, wherein a length of the body part of the first packet is equal to the length of the second packet.

18. The non-transitory computer-readable storage medium of claim 17, wherein the header part of the first packet includes information regarding an origin of the first packet and a destination of the first packet.
