1. An apparatus operable for transmitting orthogonal frequency division multiplexing (OFDM) signals for communication in a wireless communication system, the apparatus comprising:

  • one or more signal reception components for receiving a signal indicating reception capabilities of another apparatus operable for communication in the wireless communication system;

    signal generation and transmission components for generating and transmitting to the other device an OFDM signal comprising a plurality of subcarriers arranged in a frequency channel;

    wherein the signal generation and transmission components allocate substantially no power to a first arbitrary number of subcarriers at a first edge of the frequency channel and a second arbitrary number of subcarriers at a second edge of the frequency channel; and

    wherein the first arbitrary number of subcarriers and the second arbitrary number of subcarriers are determined as a function of the reception capabilities of the other apparatus, wherein the reception capabilities indicate that the first arbitrary number of subcarriers and the second arbitrary number of subcarriers are not usable by the other apparatus.
