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: An embodiment method includes receiving, by an access point (AP), a first authentication request from a station (STA) that requests authentication of the STA, transmitting, by the AP, a second authentication request to a server that requests including extensible authentication protocol (EAP) authentication signaling to verify mutual possession of a shared key between the STA and the server, and receiving, by the AP, a first authentication response from the server in response to the second authentication request. The first authentication response includes an indication that authentication of the STA was successful. The method further includes transmitting, by the AP, a second authentication response to the STA, and receiving, by the AP, an association request that includes a message integrity code (MIC) from the STA.

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.

Abstract: A method includes transmitting, by a station to an access point (AP), a fast initial link setup (FILS) authentication request and transmitting, by the station to the AP, an authorization request, where the authorization request includes an extensible authentication protocol (EAP) over local area network (LAN) (EAPOL) key. The method also includes receiving, by the station from the AP, an association response, where the association response includes the EAPOL key.

Abstract: Signal (SIF) field capacity can be significantly increased by encoding SIG field data using two streams in accordance with a space-time block code (STBC) encoding scheme. Dual-stream SIG field encoding allows for the utilization of higher order modulation schemes, such as quadrature phase-shift keying (QPSK), which increases SIG field capacity. Dual-stream encoded SIG fields are transmitted using an omnidirectional beam to allow mobile stations to accurately decode the SIG field irrespective of their spatial location.
