description This disclosure provides methods, devices and systems that support communicating using orthogonal frequency division multiple access (OFDMA) according to a tone plan that supports 20 MHz subchannel puncturing within a wireless channel. In some aspects, a non-legacy tone plan may define a set of tones for a resource unit (RU) such that the RU does not overlap a 20 MHz subchannel boundary of the wireless channel. The locations of the set of tones in the non-legacy tone plan may be shifted relative to corresponding tones associated with a corresponding RU according to a legacy tone plan. One or more of the disclosed tone plans may enable puncturing of subchannels while making use of some RUs that would otherwise partially overlap a punctured subchannel in the legacy tone plan.
