Abstract: Embodiments of a high-efficiency Wi-Fi (HEW) station, access point (AP), and method for communication in a wireless network are generally described herein. In some embodiments, the HEW AP may transmit a resource allocation message to indicate an allocation of channel resources for uplink transmissions by one or more HEW stations. The channel resources may include multiple channels, each of which may include multiple sub-channels and an extra portion of channel resources. The resource allocation message may include multiple sub-channel allocation blocks to indicate an allocation for a particular HEW station. A length of the sub-channel allocation blocks may be based on various factors, such as a number of channels included in the channel resources and a sub-carrier bandwidth.

Abstract: Apparatuses, methods, and computer readable media for signaling clear-channel assessment parameters in a high-efficiency wireless local area network (HEW) are disclosed. A HEW master station comprising circuitry is disclosed. The circuitry may be configured to determine one or more clear-channel assessment (CCA) parameters for one or more HEW stations, and transmit a CCA parameter of the one or more CCA parameters to the corresponding HEW station of the one or more HEW stations. The clear-channel assessment parameter may be one from the following group: mid-packet detect (MPD) threshold, energy detect threshold, and signal detect threshold. The HEW master station may determine the CCA parameter based on the at least one of the following group: an uplink signal strength of the HEW device, a signal quality report received from the HEW device, and a downlink signal strength of the master station received by the HEW device.

Abstract: Embodiments of a LP-WUR (low-power wake-up radio) wake-up packet acknowledgement procedure are generally described herein. A first wireless device encodes for transmission of a wake-up packet of a LP-WUR to a second wireless device, the wake-up packet to wake up a WLAN (wireless local area network) radio of the second wireless device. Upon decoding a response frame from the second wireless device received during a predefined time period: the first wireless device encodes for transmission of a data packet to the WLAN radio of the second wireless device. Upon failing to receive the response frame from the second wireless device during the predefined time period: the first wireless device encodes for retransmission of the wake-up packet to the second wireless device.

Abstract: Embodiments of a high-efficiency Wi-Fi (HEW) station, access point (AP), and method for random access contention in a wireless network are generally described herein. In some embodiments, the HEW station may receive a beacon frame that indicates a number of trigger frames (TFs) included in a beacon interval. The beacon frame may be received from an HEW access point (AP) in channel resources that include multiple sub-channels. The HEW station may receive a random access TF that indicates a random access portion of the sub-channels that are allocated for random access contention during an uplink transmission period. The HEW station may select a candidate sub-channel from the channel resources. When the candidate sub-channel is included in the random access portion, the HEW station may transmit an association request (AR) frame on the candidate sub-channel during the uplink transmission period.

Abstract: Described are methods and devices for increasing the efficiency of Wi-Fi networks by increased spatial reuse, which refers to sharing the same wireless spectral resources over different spatial regions. A described technique for doing this is for a Wi-Fi device to increase the threshold of the clear channel assessment (CCA) so as to ignore and regard as interference the transmissions from other devices. The sensing range of the Wi-Fi device then decreases, and the spatial resource can be reused by different Wi-Fi devices in different spatial locations.
