Physical layer data unit format
First Claim
1. In a wireless communication system wherein communication devices exchange information utilizing data units that conform to a first format, wherein the first format includes a short training field (STF) spread with a first spread code and a first cover code, a method for generating a physical layer (PHY) data unit that conforms to a second format, wherein the PHY data unit is for transmitting PHY information, the method comprising:
- generating a first portion of the PHY data unit to indicate the PHY data unit conforms to the second format, wherein the first portion of the PHY data unit includes an STF spread with at least one of a second spread code different than the first spread code or a second cover code different than the first cover code; and
generating a second portion of the PHY data unit according to the second format, wherein the second portion of the PHY data unit includes PHY information elements not specified by the first format.

Abstract
In a wireless communication system wherein communication devices exchange information utilizing data units that conform to a first format, wherein the first format includes a short training field (STF) spread with a first spread code and a first cover code, a method is for generating a physical layer (PHY) data unit that conforms to a second format, wherein the PHY data unit is for transmitting PHY information. A first portion of the PHY data unit is generated to indicate the PHY data unit conforms to the second format, wherein the first portion of the PHY data unit includes an STF spread with at least one of a second spread code different than the first spread code or a second cover code different than the first cover code. A second portion of the PHY data unit is generated according to the second format, wherein the second portion of the PHY data unit includes PHY information elements not specified by the first format.

20. In a wireless communication system wherein communication devices exchange information utilizing data units that conform to a first format, wherein the first format includes a short training field (STF) spread with a first spread code and a first cover code, a method for processing a physical layer (PHY) data unit that conforms to a second format, wherein the PHY data unit is for transmitting PHY information, the method comprising:
-
analyzing a first portion of a received data unit to determine if the received data unit is a PHY data unit, wherein the first portion of the received data unit includes an STF; wherein analyzing the first portion of a received data unit to determine if the received data unit is a PHY data unit comprises determining at least one of
1) whether the STF of the received data unit is spread with a second spread code different than the first spread code or
2) whether the STF of the received data unit is spread with a second cover code different than the first cover code;wherein the method further comprises utilizing PHY information elements in a second portion of the PHY data unit to perform a PHY function if the received data unit is a PHY data unit, wherein the second portion of the PHY data unit conforms to the second format, and wherein the PHY information elements are not specified by the first format. - View Dependent Claims (21, 22, 23, 24, 25, 26)
