Abstract: This disclosure describes systems, methods, and devices related to using enhanced high efficiency (HE) frames. A device may determine a high efficiency signal-B (HE-SIG-B) field for a high efficiency (HE) frame, the HE-SIG-B field comprising a common information field and a user information field. The device may determine a data portion of the HE frame, wherein the data portion includes one or more resource units (RUs) with a size equal to a number of tones. The device may determine a first resource allocation subfield and a second resource allocation subfield of the common information field based at least in part on the number of tones. The device may cause to send the HE frame.

Abstract: Methods, apparatuses, and computer readable media for location measurement reporting in a wireless network are disclosed. An apparatus of a responder station is disclosed, the apparatus comprising processing circuitry configured to derive bits from a temporary key, and generate a first sequence and a second sequence using the bits, wherein the first sequence and second sequence comprise one or more symbols. The processing circuitry is further configured to concatenate the first sequence and the second sequence to form a new first sequence comprising the first sequence and the second sequence, and concatenate a modified first sequence and a modified second sequence to form a new second sequence. The processing circuitry may be configured to repeat a number of times the concatenate the first sequence through the concatenate the modified first sequence.

Abstract: This disclosure describes systems, methods, and devices related to a flexible connectivity framework. A first device may send a trigger frame to a second device. The first device may then receive an uplink bandwidth resource request from the second device. The first device may detect a high efficiency-long training field (HE-LTF) in the uplink bandwidth resource request. The first device may send an uplink multiuser trigger frame, and the first device may receive an uplink frame from the second device.
