Patent ID: 7929626

Claim:
A method of receiving a transmitter signal with varying power, the method comprising: providing bit-loading information for each tone of multiple tones, wherein the multiple tones include a first set of tones and a second set of tones; receiving for each tone of the first set of tones a first bit sequence constellation symbol, wherein there is a difference of m bits between the bit size of the first bit sequence constellation symbol on each tone of the first set of tones and the bit-loading information associated with each tone of the first set of tones; producing, based upon the first bit sequence constellation symbol on each tone of the first set of tones, off of each tone of the first set of tones bits to generate a first bit sequence, wherein there is the difference of m bits between the bits produced off each tone of the first set of tones and the bit-loading information associated with each tone of the first set of tones, and m is an integer greater than or equal to 0; receiving for each tone of a second set of tones a second bit sequence constellation symbol; determining, for the second set of tones on each of which a second bit sequence constellation symbol is received, a cutback indication; determining that the cutback indication is indicative of a difference of n bits between the bit size of the second bit sequence constellation symbol on each tone of the second set of tones and the bit-loading information associated with each tone of the second set of tones; producing, based upon 1) the second bit sequence constellation symbol on each tone of the second set of tones, 2) the value of n, and 3) the bit loading information associated with each tone of the second set of tones, off of each tone of the second set of tones bits to generate a second bit sequence, wherein there is the difference of n bits between the bits produced off of each tone of the second set of tones and the bit-loading information associated with each tone of the second set of tones, and n is an integer greater than or equal to 0 and m is not equal to n.
