Dynamic channelization code allocation

A wireless communication system, comprising:

• a channel mapper for:
• receiving a variable rate data frame;
• apportioning the variable rate data frame into a primary data block and one or more secondary data blocks, the primary data block sized for transmission at a fixed rate, the one or more secondary data blocks comprising the remainder of the variable rate data frame;
• determining one or more secondary rates in accordance with the one or more secondary data blocks;
• forming a primary data frame comprising the primary data block and an indicator identifying a code associated with at least one of the secondary rates;
• and
• forming one or more secondary data frames comprising the one or more secondary blocks;
• respectively.

A method for transmitting a variable rate data frame, comprising:

• determining one or more secondary rates in accordance with the one or more secondary data blocks;
• forming a primary data frame comprising the primary data block and an indicator identifying a code associated with at least one of the secondary rates;
• and
• forming one or more secondary data frames comprising the one or more secondary blocks, respectively.

A method for transmitting a variable rate signal comprising a plurality of frames, the rate of each frame corresponding to one of a plurality of supported rates, the method comprising:

• identifying a first portion of a frame suitable for transmission at the lowest supported rate, the first portion being the entire frame when the frame rate is the lowest supported rate;
• transmitting the first portion of the frame on a first channel with a fixed code, the rate of the fixed code being the lowest supported rate;
• determining a second code such that the rate of the second code is sufficient to transmit a second portion of the frame when the frame rate is greater than the lowest supported rate;
• transmitting a code indicator on the first channel, the code indicator identifying the second code when the frame rate is greater than the lowest supported rate and indicating no second code when the frame rate is equal to the lowest supported rate;
• and
• transmitting the second portion of the frame on a second channel in accordance with the second code when the frame rate is greater than the lowest supported rate.

A method for receiving a variable rate signal comprising a plurality of frames, the rate of each frame corresponding to one of a plurality of supported rates, the method comprising:

• receiving a first portion of the frame on a first channel with a fixed first code, the rate of the first fixed code being the lowest supported rate;
• decoding a code indicator from the received first portion of the frame, the code indicator identifying a second code when the frame rate is greater than the lowest supported rate and indicating the received first portion of the frame is the entire frame when the frame rate is the lowest supported rate;
• and
• receiving a second portion of the frame on a second channel in accordance with the second code when the code indicator identifies a second code.
