Abstract: This disclosure describes systems, methods, and apparatus related to a restrictive target wake time (TWT) service period (SP) system. A device may determine a beacon frame to be sent to one or more power save devices. The device may determine a time duration of a TWT SP associated with the one or more power save devices. The device may determine a first trigger frame including a cascade indication. The device may determine a first time associated with the first trigger frame. The device may cause to send the trigger frame to the one or more power save devices based at least in part on a remaining duration of the TWT SP.

Abstract: Methods, apparatuses, and computer-readable medium are described for doing fine timing measurements for one or more stations. A trigger frame is encoded for stations. Uplink null data packets are received. A time of arrival for the UP NDP and a time of departure for a downlink null data packet are determined. The time of arrival and time of departure are encoded into a data packet, such as a downlink null data packet announcement. A wireless device is configured to transmit the data packet to a station.

Abstract: Apparatuses, computer readable media, and methods for scheduling trigger frames in a high-efficiency wireless (HEW) local-area network are disclosed. An apparatus of a HEW master station is disclosed. The HEW master station includes transceiver circuitry and processing circuitry configured to transmit a random access trigger frame (TF-R) to a plurality of HEW stations, and receive resource requests from one or more of the plurality of HEW stations in response to the TF-R. The transceiver circuitry and processing circuitry is further configured to transmit an indication when a trigger frame is to be transmitted. The trigger frame is to comprise resource allocations in response to the resource requests. An apparatus of a HEW station may enter a power save mode until a time when a trigger frame is scheduled that includes resource allocations in response to resource requests transmitted to a master station from the HEW station.

Abstract: Computing readable media, apparatuses, and methods for signaling for uplink sounding are disclosed. An apparatus is disclosed comprising processing circuitry. The processing circuitry may be configured to: decode a trigger frame comprising a resource unit (RU) allocation, and a spatial stream (SS) allocation for the first wireless device to transmit an uplink (UL) sounding signal, where the trigger frame include an indication that the trigger frame is for the UL sounding signal. The processing circuitry may be further configured to: determine a path loss based on the indication of the transmit power and a received power of the trigger frame at the first wireless device. The processing circuitry may be configured to: determine a transmit power for the UL sounding signal based on the path loss, and transmit the UL sounding signal in accordance with the RU allocation, the SS allocation, and the transmit power.

Abstract: An apparatus of a first high-efficiency (HE) access point (AP) or station for spatial reuse is the disclosed. The apparatus includes processing circuitry configured to: decode a first portion of a first packet; and if the first portion indicates the first packet was transmitted by a second HE AP or station and that the first packet is an overlapping basic service set (OBSS) packet, then if a preamble detect energy is below a threshold, cause to be transmitted a second packet simultaneously with a portion of the first packet after the first portion. The processing circuitry may be configured to determine the first portion was transmitted by the second HE AP or station if a field in a physical (PHY) header or a second field in a media access control (MAC) header indicate the first packet was transmitted by the second HE AP or station.
