Abstract
Systems and methods for extending header fields are disclosed. The header field may be extended without changing the current size of the header. Reserve bits may be used to indicate the use of an extended header and the extended header may be store in a variety of locations within the frame, including the frame payload or pad bits.
Claims39
A communication device for transmitting at least a first packet in a wireless communication system, wherein the first packet comprises a header field, a payload field, and a padding field, the communication device comprising:
- a memory configured to store a first extension header;
- a message formatter in communication with the memory, the message formatter configured to:
- indicate in the header field the presence of the first extension header, and
- insert at least one portion of the first extension header in at least one of the payload field and the padding field of the first packet, the payload field and the padding field being separate from the header field.
A communication device for transmitting at least a first packet in a wireless communication system, wherein the first packet comprises a header field, a payload field, and a padding field, the communication device comprising:
- means for storing a first extension header;
- and
- means for indicating in the header field the presence of the first extension header and inserting at least one portion of the first extension header in at least one of the payload field and the padding field of the first packet, the payload field and the padding field being separate from the header field, wherein the indicating and inserting means is in communication with the storing means.
A method of communicating at least a first packet in a wireless communication system, wherein the first packet comprises a header field, a payload field, and a padding field, the method comprising:
- storing a first extension header;
- and
- indicating in the header field of the first packet the presence of the first extension header and inserting at least one portion of the first extension header in at least one of the payload field and the padding field of the first packet, the payload field and the padding field being separate from the header field.
A computer readable product, comprising:
- a non-transitory computer-readable storage medium encoded with instructions that, when executed by a computer, cause the computer to:
- store a first extension header of a first packet comprising a header field, a payload field, and a padding field;
- and
- indicate in the header field of the first packet the presence of the first extension header and insert at least one portion of the first extension header in at least one of the payload field and the padding field of the first packet, the payload field and the padding field being separate from the header field.
