A wireless transmitter station using a resource unit (RU) or multiple resource unit (MRU) of an Orthogonal Frequency Division Multiplexing (OFDM) or Orthogonal Frequency Division Multiple Access (OFDMA) communication is disclosed. The wireless transmitter station is configured to allocate a first subset of a plurality of tones of the RU or MRU as data tones for carrying modulated data based on the bit sequence and to allocate a second subset of the plurality of tones of the RU or MRU as interference mitigation (IM) pilot tones for carrying a plurality of predefined IM pilot symbols. Moreover, the wireless transmitter station is configured to permute the plurality of tones of the RU or MRU, including both the first subset comprising N S ⁢ D IM data tones and the second subset comprising N SP IM IM pilot tones, for obtaining a plurality of permuted tones of the RU or MRU.
