摘要： A station (STA), an access point (AP) and method of adjusting for detection of an Overlapping Basic Service Set (OBSS) packet is disclosed. The STA may initiate a counter in response to determining that a BSS packet is to be transmitted. A packet may be detected on the channel and the counter suspended. If the packet is a BSS packet, the counter may be reset and restarted. If the packet is an OBSS packet, the counter may be decremented by a time to detect and determine that the packet is the OBSS packet and subsequently restarted prior to transmitting the BSS packet when the counter reaches 0. The counter may be further decremented by an Inter Frame Space period. If the counter after being decremented is 0, the BSS packet may be transmitted immediately, the counter may not be decremented or may be incremented by a backoff window.

摘要： 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.

摘要： An apparatus for a station (STA) is generally described herein. The STA includes a low-power WUR (LP-WUR), a local timing synchronization function (TSF) timer, and processing circuitry. The processing circuitry can decode a signal received from an access point (AP) at the LP-WUR, the signal including a TSF value, the TSF value including a subset of octets of a TSF timer associated with the AP. The STA can synchronize the local TSF timer of the STA with the TSF timer associated with the AP by adjusting a local TSF timer based on a count of a number of octets included in the subset of octets. The LP-WUR can wake up a wireless local area network (WLAN) radio of the STA at a wake-up time based on the local TSF timer. Other methods, apparatuses and systems are also described.
