Abstract: This disclosure describes systems, methods, and devices related to null data packet (NDP) feedback report. A device may cause to send an NDP feedback report frame to one or more station devices, wherein the NDP feedback report frame comprises one or more resource allocations. The device may identify an allocation response using a first allocation of the one or more resource allocations from a first station device. The device may determine to assign one or more timeslots as contention based resources based on the allocation response.

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.

Abstract: Embodiments of a station (STA), access point (AP) and method for rate adaption are generally described herein. The STA may receive a medium access control protocol data unit (MPDU) encoded in accordance with a first modulation and coding scheme (MCS). The STA may detect bit errors of the MPDU based on a comparison between the received MPDU and the decoded MPDU. The STA may determine an MCS reception margin parameter based at least partly on a comparison between a number of detected bit errors and a predetermined threshold of bit errors. The STA may transmit a block acknowledgement (BA) frame that includes the MCS reception margin parameter. The MCS reception margin parameter may enable a rate adaptation, from the first MCS to a second MCS for a subsequent MPDU for the STA.

Abstract: This disclosure describes systems, methods, and apparatus, related to a short resource request. A device may identify one or more high efficiency long training (HE-LTF) fields received from at least one of one or more first devices. The device may determine one or more bits associated with the one or more HE-LTF fields. The device may determine an uplink orthogonal frequency division multiple access (OFDMA) request based at least in part on the one or more bits.

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.
