Patent ID: 7535972

Claim:
A transmitter within a radio transceiver for generating a frame in a frame format according to one of a plurality of operating modes for transmission of the frame over a plurality of tones in a channel, the transmitter comprising: a frame structure table for storing a respective frame format for each of the plurality of operating modes, each frame format including a respective entry for each frame segment of the frame, each entry including a segment type and a pointer for the respective segment type, the segment type of the entry corresponding to a data segment in the frame being a data type; data tone map tables for storing respective operating mode data segment formats of the data segment for each of the operating modes, each of the operating mode data segment formats including respective tone data segment formats for each of the tones, the pointer in the entry of the frame structure table for the data type pointing to one of the operating mode data segment formats; a frame structure engine operably coupled to receive a mode selection signal indicative of a select operating mode, wherein the frame structure engine is operable to access the frame structure table and data tone map tables to determine the frame format, including the operating mode data segment format, of the select operating mode and produce a control signal to control frame generation in the frame format and operating mode data segment format of the select operating mode; and a frame generator operably coupled to receive the control signal and to generate a frame in the frame format and operating mode data segment format of the select operating mode in response to the control signal.
