1. A method, comprising:
generating a physical-layer protocol data unit (PPDU) with subcarriers of a resource unit (RU) distributed on a frequency subblock of a plurality of frequency subblocks of a wide bandwidth; and
transmitting the PPDU over the wide bandwidth,
wherein each of the plurality of frequency subblocks comprises a 20 MHz, 40 MHz or 80 MHz frequency subblock,
wherein the wide bandwidth comprises an 80 MHz, 160 MHz or 320 MHz bandwidth,
wherein the subcarriers of the RU are distributed on the frequency block by applying a constant shift to a distributed-tone RU (dRU) on a 20 MHz, 40 MHz or 80 MHz bandwidth, and
wherein a distribution of the subcarriers of the RU on the frequency subblock is expressed by:
kdRU_i=kdRU+Kshift(i),
wherein:
kdRu denotes dRU subcarrier indices for the dRU on the 20 MHz, 40 MHz or 80 MHz bandwidth,
kdRu i denotes dRU subcarrier indices on an ith frequency subblock,
kshift(i) denotes a value of the constant shift, and
i denotes a frequency subblock index of the plurality of frequency subblocks.
