Interference management in a wireless communication system using frequency selective transmission

An apparatus for communication, comprising:

• an interference controller configured to determine a transmit waveform from among a plurality of N allocated waveforms of an unplanned access point to an associated access terminal, wherein the plurality of N allocated waveforms are formed from coefficients of an N-tap channel filter with each coefficient set being derived from a specific row in an N×N digital Fourier transform matrix, the transmit waveform exhibiting a highest channel quality in the presence of interference with the associated access terminal over others of the plurality of allocated waveforms, and wherein the channel quality with the associated access terminal is tested for each of the plurality of allocated waveforms;
• and
• a communication controller configured to transmit signals according to the transmit waveform from the unplanned access point to the associated access terminal.
