Abstract

A system and method for wireless communication is disclosed. In one aspect, the method comprises generating a physical (PHY) frame comprising a PRY layer header and a PHY payload data packet, wherein the PHY layer header comprises an aggregation indication bit for indicating whether the PHY payload data packet comprises two or more sub-packets received from the application layer. The method further comprises transmitting the PHY frame.

Claims

1. A method of transmitting data in a wireless network, the method comprising:

generating a physical (PHY) layer frame comprising a PHY layer header and a PHY layer payload data packet, wherein the PAY layer header comprises an aggregation indication bit for indicating whether the PRY layer payload data packet comprises two or more sub-packets received from the application layer; and

transmitting the PHY layer frame.

2. The method of claim 1, wherein the transmitting of the PHY layer frame comprises transmitting the PAY layer frame in a beam-formed mode.

3. The method of claim 1, wherein the PHY payload data packet comprises two or more sub-packets, and wherein the PHY payload data packet further comprises a plurality of acknowledgement (ACK) groups, at least one ACK group further comprising:

a set of sub-packets; and

an ACK group CRC segment for a cyclic redundancy checksum for checking transmission of the set of sub-packets.

4. The method of claim 3, wherein the PHY header further comprises an ACK group length field for at least one ACK group, the ACK group length field indicating the length of the ACK group.

5. The method of claim 3, wherein at least one sub-packet further comprises:

a sub-packet CRC segment for a cyclic redundancy checksum for checking transmission of the sub-packet; and

a media access control (MAC) payload data packet.

6. The method of claim 5, wherein each sub-packet further comprises a media access control (MAC) header for the sub-packet.

7. The method of claim 6, wherein the MAC header comprises a packet type field indicating the MAC type of the sub-packet.

8. The method of claim 6, wherein the MAC header is of a fixed length, and wherein at least one sub-packet further comprises a MAC header extension of a variable length.

9. The method of claim 5, wherein the frame further comprises a MAC header for the frame.

10. The method of claim 9, wherein the MAC header is of a fixed length, and wherein the frame further comprises a MAC header extension of a variable length.

11. The method of claim 9, wherein the PHY header further comprises an ACK group mode field for at least one ACK group, the mode field indicating the PRY mode of the ACK group.

12. The method of claim 1, wherein the wireless network is a high data rate 60 GHz millimeter wave wireless network.

13. The method of claim 1, wherein the PRY layer frame further comprises a PHY preamble, a fixed-length media access control (MAC) header, and a variable-length MAC header extension, and wherein the PHY payload data packet comprises only one packet received from the application layer.

14. The method of claim 1, wherein the transmitting of the PHY layer frame comprises transmitting the PHY layer frame in an omni-directional mode.

15. The method of claim 1, wherein the PHY payload data packet further comprises two or more sub-packets.

16. The method of claim 15, wherein at least one sub-packet further comprises:

a sub-packet CRC segment for a cyclic redundancy checksum for checking transmission of the sub-packet; and

a media access control (MAC) payload data packet.

17. The method of claim 15, wherein at least one sub-packet further comprises a media access control (MAC) header for the sub-packet.

18. The method of claim 17, wherein the MAC header for the sub-packet is of a fixed length, and wherein at least one sub-packet further comprises a MAC header extension of a variable length.

19. The method of claim 17, wherein the MAC header comprises a packet type field indicating the MAC type of the sub-packet.

20. The method of claim 16, wherein the frame further comprises a MAC header for the frame.

21. The method of claim 20, wherein the MAC header for the frame is of a fixed length, and wherein the frame further comprises a MAC header extension of a variable length.

22. A system for transmitting data in a wireless network, the system comprising:

means for generating a physical (PRY) layer frame comprising a PHY header and a PHY payload, the PHY payload comprising one or more packets from the application layer, wherein the PRY header comprises an aggregation indication bit for indicating whether the PHY payload comprises two or more packets from the application layer; and

means for transmitting the PHY frame.

23. A system for transferring data in a wireless network, the system comprising:

a transmitter configured to

     1) generate a physical (PHY) layer frame comprising a PHY header and a PHY payload, the PHY payload comprising one or more packets from the application layer, wherein the PHY header comprises an aggregation indication bit for indicating whether the PHY payload comprises two or more packets from the application layer, and

     2) transmit the PHY frame; and

a receiver configured to receive a PHY frame from the transmitter, determine whether the frame is aggregated based on the aggregation indication field, and process the PHY frame based on whether the frame is aggregated.
