A method, apparatus and medium of communication determine a transmit waveform from among a plurality of allocated waveforms of an unplanned access point to an associated access terminal. The transmit waveform exhibiting a highest channel quality with an associated access terminal over others of the plurality of allocated waveforms is determined. Signals are transmitted according to the transmit waveform from the unplanned access point to the associated access terminal. | 2014-08-21 |
