Abstract: A method performed by a STA may comprise receiving data of a MU-HE-PPDU, from an AP. The MU-HE-PPDU may comprise a HE-SIG-A field, a first HE-SIG-B portion and a second HE-SIG-B portion. The first HE-SIG-B portion may be received on a first channel and the second HE-SIG-B portion may be received on a second channel which is different than the first channel. The first HE-SIG-B portion may include one or more STA identifiers.

Abstract: Device, systems, and/or techniques for using sub-channel signaling information between an access point and a first station are disclosed. An uplink trigger sent from the access point to the first station may be received. A map may be transmitted from the first station indicating at least one sub-channel that is available for spatial sharing by a second station. The first station may receive an acknowledgement from the access point that data was transmitted from the second station on the at least one sub-channel and/or received by the at least one access point. An OFDMA transmission having a sub-channel/sub-band available for transmitting data may be determined. An energy in the sub-channel/sub-band may be measured and/or compared to a dynamic and/or static threshold. Whether a sub-channel/sub-band is free or busy may be determined for example based on if the measured energy is, or is not, greater than the threshold.
