Devices and methods for reliable communication in a wireless network

A method for transmitting a bit sequence to a wireless receiver station over a wireless channel 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, the method comprising:

• allocating 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, the first subset comprising
• N
• S
• ⁢
• D
• IM
• data tones;
• allocating 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, the second subset comprising
• N
• SP
• IM
• IM pilot tones;
• permuting the plurality of tones of the RU or MRU for obtaining a plurality of permuted tones;
• mapping the plurality of permuted tones onto a plurality of frequency subcarriers of the RU or MRU for generating a modulated signal;
• and
• transmitting the modulated signal over the wireless channel to the wireless receiver station.

A non-transitory computer-readable medium storing instructions that, when executed by one or more processors of a wireless transmitter station, cause the wireless transmitter station to perform a method for transmitting a bit sequence to a wireless receiver station over a wireless channel 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 system, the method comprising:

• allocating, by the one or more processors, 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, the first subset comprising
• N
• SD
• IM
• data tones;
• allocating, by the one or more processors, 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, the second subset comprising
• N
• SP
• IM
• IM pilot tones;
• permuting, by the one or more processors, the plurality of tones of the RU or MRU for obtaining a plurality of permuted tones;
• mapping, by the one or more processors, the plurality of permuted tones onto a plurality of frequency subcarriers of the RU or MRU to generate a modulated signal;
• and
• causing transmission of the modulated signal over the wireless channel to the wireless receiver station.
