Claim 26:
27. A station (STA), comprising:
a wireless receiver;
a wireless transmitter; and
a processor configured to:
operate the wireless receiver to receive information corresponding to a first frequency range being used by the station, said information identifying a set of resource units (RUs) in the first frequency range that are subject to a lower power spectral density (PSD) constraint than other resource units or channels in the first frequency range or which are not to be used;

operate the STA to perform one or more of: i) transmitting data in a first frame which uses the first frequency range but which leaves at least some RUs which are subject to the lower PSD constraint or which are not to be used, unused by the first frame or ii) decoding a received frame assuming that no data was transmitted on RUs, which said information indicated are subject to the lower PSD constraint or are not to be used; and
wherein, as part of being configured to operate the STA to transmit data in the first frame, the processor is configured to control the STA to puncture RUs which are subject to the lower PSD constraint or which are not to be used.
