1. A method, comprising:
distributing a plurality of subcarriers of a resource unit (RU) over a bandwidth to generate a distributed-tone RU(dRU) or a distributed-tone multi-RU(dMRU); and
communicating with a communication entity using the dRU or the dMRU,
wherein the distributing of the plurality of subcarriers of the RU to generate the dRU or the dMRU comprises distributing the plurality of subcarriers of the RU with a predefined span over each 20 MHz frequency segment or subblock in the bandwidth and with a gap of at least a minimum size around a center direct-current (DC) tone in a distribution pattern of the plurality of subcarriers to result in reduction in a peak-to-average power ratio (PAPR) in communicating with the communication entity.
