Abstract: Methods, computer readable media, and wireless apparatuses are disclosed for a TXOP duration field. An apparatus is disclosed comprising processing circuitry configured to: encode a first high efficiency (HE) physical-layer convergence procedure (PLCP) protocol data unit (PPDU) comprising a transmission opportunity (TXOP) duration field in a first physical-layer portion of the first HE PPDU. The processing circuitry may be further configured to set the TXOP duration field value to indicate a largest duration value representable by the TXOP duration field that is equal to or less than a duration value indicated by the first MAC duration field, if the first HE PPDU is to include a first media access control (MAC) duration field in a first MAC-layer portion of the first HE PPUU.

Abstract: Logic to “loosely” manage synch frame transmissions in a synch network via the devices synched to the network that implement the logic. Logic may distributedly adjust the frequency of attempting synch frame transmissions without estimating the size of the neighborhood. Logic in devices of a synch network to let each device maintain a Transmission Window (TW). Logic to determine the frequency of attempting synch frame transmissions based upon the TW. Logic to increase TW if the device detects a synch frame transmission. Logic to decrease TW if the device successfully transmits a synch frame. Logic to balance power consumption and discovery timing by adjusting the decrease in TW responsive to a synch transmission in relation to the increase in TW responsive to detection of a synch transmitted by another device.

Abstract: Methods, computer readable media, and wireless apparatuses are disclosed for a TXOP duration field disable setting in a HE preamble, such as HE-SIG-A. An apparatus of a wireless device can include processing circuitry configured to decode a HE PPDU received from a second wireless device, the HE PPDU including a first TXOP duration field in a PHY portion of the HE PPDU. The processing circuitry can detect whether the TXOP duration field includes a disable flag based on bit values of the TXOP duration field. The disable flag can indicate absence of duration information in the TXOP duration field. Upon detecting the disable flag, a response HE PPDU can be encoded for transmission to the second wireless device. The response HE PPDU can include a second TXOP duration field with a disable flag within a PHY portion of the response HE PPDU.

Abstract: Methods and systems for authenticated wake-up radio frames are disclosed. In one aspect, a method includes generating a wake-up radio (WUR) integrity group key (IGTK) for authentication of WUR frames when received by a wake-up radio (WURx). The WUR IGTK may be identified via a key identifier in the WUR frame. The key identifier may be updated when the WUR IGTK is updated, facilitating WUR IGTK key updating across multiple associated stations.
