Abstract: A method and system for LBT or CCA threshold setting for directional reception and transmission are provided. In an embodiment, a method in a wireless device for determining if a channel is clear in an unlicensed band channel in a wireless network includes detecting, with the wireless device, an energy along a first beamforming direction. The method also includes determining, with the wireless device, an energy detection threshold. The method also includes determining, with the wireless device, whether the unlicensed band channel is clear in at least the first receiving direction according to the energy and the energy detection threshold.

Abstract: A method, apparatus and system for transmitting control information in a header of a physical protocol data unit (PPDU), such as an IEEE 802.11 compliant PPDU. Embodiments include indicating control features in an EDMG PPDU for Wireless LAN communications. The method and system may include overloading at least one bit of a Scrambler Initialization Field in the PPDU header (e.g. the PHY header) to convey control information, as well as to be used to initialize the scrambler shift register. The same header bits are thus used for both purposes. Examples of control information include a primary channel, channel width or MIMO configuration to be used in further communication.

Abstract: A procedure and frame structure for Wi-Fi sensing is described. An aspect of the disclosure provides a method of sensing. Such the method includes sending, by an initiating station (STA) to a plurality of responder STAs, a sensing request comprising a sensing announcement frame indicating identifiers (ID) of the plurality of responder STAs. Such a method further includes receiving, by the initiating STA from the plurality of responder STAs, one or more responses based on the sensing request. In some embodiments, the announcement frame further indicates resource unit assignments for receiving acknowledgements from the plurality of responder STAs. In some embodiments, the method further includes receiving, by the initiating STA from the plurality of responder STAs, the acknowledgements indicating a willingness to participate in the sensing procedure.

Abstract: The AP can generate a distinctive 8 bit value, and fill the 8 most significant bits (MSBs) of the a 16 bit AID field to form a EDMG BSS AID. Beamforming can include a station performing a sector level sweep (SLS) process including transmitting, in sequence, a plurality of short sector sweep (SSW) frames to the other station using corresponding ones of the antenna sectors, and receiving, in sequence, a plurality of the short SSW frames from the other station, the short SSW frames having an addressing field format specifying a receiver address association ID (RA AID) and a transmitter address association ID (TA AID). The distinctive 8 bit value can be used as the AP AID.
