Abstract:
A wireless communication terminal is disclosed for wireless communication. This terminal includes a transceiver and a processor. The processor is configured to transmit a non-legacy physical layer frame. This frame incorporates a legacy signaling field that contains information decipherable by an older, "legacy" wireless communication terminal, using the transceiver.

Plain-Language Overview of Independent Claims:

• Independent Claim 1 (Apparatus Claim): This claim describes a wireless communication device (terminal) that is designed to operate in an environment where both new ("non-legacy") and older ("legacy") wireless devices exist. The device has a transceiver for sending and receiving signals and a processor to handle communications. The processor is configured to receive a non-legacy data packet (physical layer frame) that includes a part understandable by legacy devices, called a "legacy signaling field." From this legacy field, the processor extracts "length information" indicating the total duration of the non-legacy frame. It also calculates additional information from a "remaining value" derived by dividing the length information by a standard data size (3 octets for a 6 Mbps legacy frame symbol). Finally, the processor uses a specific mathematical formula to determine the precise number of data symbols within the non-legacy physical layer frame.

• Independent Claim 9 (Method Claim): This claim outlines a method (a series of operational steps) for a wireless communication terminal to perform wireless communication. The method involves receiving a non-legacy physical layer frame that contains a legacy signaling field which can be decoded by a legacy wireless communication terminal. The method then proceeds to obtain "length information" from this legacy signaling field, which indicates the duration of the non-legacy physical layer frame. Subsequently, it involves obtaining other information by using a "remaining value" derived from dividing the length information by a specific data size (which is 3 octets for a legacy physical layer frame symbol at a 6 Mbps data rate). The final step is to determine the number of data symbols in the non-legacy physical layer frame using the same mathematical equation detailed in Claim 1.
