Abstract: Some demonstrative embodiments include apparatuses, systems and/or methods of terminating a Neighbor Awareness Networking (NAN) path. For example, an apparatus may include logic and circuitry configured to cause a first NAN device to transmit a message including a NAN Data Link (NDL) attribute corresponding to an NDL with a second NAN device, the NDL attribute including a Maximal (Max) Idle Period field to indicate a time period during which the second NAN device is allowed to refrain from transmitting over the NDL without the NDL being terminated; and to allow the first NAN device to terminate all NAN Data Paths (NDPs) over the NDL, if any frame is not received from the second NAN device for at least the time period indicated by the Max Idle Period field.

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.

Abstract: Methods, computer readable media, and wireless apparatuses are disclosed for trigger frame recovery. An apparatus of a wireless device is disclosed. The apparatus comprising processing circuitry configured to: encode a trigger frame comprising a resource allocation for one or more stations, where the trigger frame comprises a network allocation vector (NAV) duration. The processing circuitry may be further configured to configure the wireless device to transmit the trigger frame to the one or more stations. The processing circuitry may be further configured to configure the wireless device to contend for the wireless medium a first time, encode a retransmission of the trigger frame, and configure the wireless device to transmit the retransmission of the trigger frame to the one or more stations, if a frame is not received from the one or more stations in response to the trigger frame before a trigger frame timeout duration.

Abstract: Methods, apparatuses, computer readable media for spatial reuse for uplink multi-user transmissions. An apparatus of a station comprising processing circuitry is disclosed. The processing circuitry may be configured to decode a first portion of a physical layer convergence procedure (PLCP) protocol data unit (PPDU), and configure the station to transmit a frame, if the PPDU is an overlapping basic service set (OBSS) PPDU, and a receive power of the PPDU is below an overlapping power detect level. An apparatus of an access point comprising processing circuitry is disclosed. The processing circuitry may be configured to encode a PPDU comprising a basic service set identifier of the access point, and encode the PPDU to indicate spatial reuse (SR) delay, SR restricted, or SR not permitted. The processing circuitry may be further configured to configure the access point to transmit the PPDU.

Abstract: Embodiments of a station (STA), access point (AP) and method for determination of transmit power for spatial reuse are generally described herein. The STA may detect, in the channel, an overlapping basic service set (OBSS) physical layer convergence procedure protocol data unit (PPDU) from an OBSS AP. The STA may determine, based at least partly on an ESS color parameter included in the OBSS PPDU, whether the OBSS AP is included in the ESS network. The STA may determine an OBSS power threshold based at least partly on whether the OBSS AP is included in the ESS network. The STA may determine, based at least partly on a comparison between the OBSS power threshold and a received power of the OBSS PPDU, whether to transmit an uplink PPDU to the BSS AP in the channel during the TXOP.
