Abstract: The disclosure relates to technology for assisting a wireless a communication device to acquire access to a millimeter-wave access point (mmW AP). In some embodiments, an angular direction from a mobile wireless communication device to the mmW AP is determined. In some embodiments, the mobile wireless communication device receives information from a wireless network that helps the mobile wireless communication device determine the angular direction. In some embodiments, the signals between wireless network and mobile wireless communication device are below 6 GHz. In some embodiments, the wireless network provides the mobile wireless communication device with the angular direction. Therefore, the mobile wireless communication device is able to configure an antenna to receive and/or transmit a beam in a direction of the mmW AP. The mobile wireless communication may do so during a process of gaining access to the mmW AP.

Abstract: Mobile stations can query independent basic service set (BSS) parameters of a group of Access Points (APs) by setting a Pre-Association Message Exchange BSSID Independent (PAME-BI) bit during Wi-Fi discovery. The PAME-BI bit may be included in a Generic Advertisement Service (GAS) request to indicate that an Access Network Query Protocol (ANQP) request carried by the GAS request is querying both independent and dependent BSS parameters. In some embodiments, the PAME-BI bit is included as a field in the ANQP query, rather than the GAS request message.

Abstract: A method for providing user equipment access to millimeter wave stations through a microwave station includes receiving an indication of millimeter wave stations operating within a microwave coverage area of a microwave station. In a microwave band, information associated with the millimeter wave stations is broadcasted to user equipment in the microwave coverage area. A request is sent to the millimeter wave stations to transmit configuration signals over a microwave band. An instruction is transmitted over the microwave band to the user equipment to perform proximity measurements of the configuration signals. According to the proximity measurements, a request is sent to a particular millimeter wave station to transmit beamforming signals over a millimeter wave band. An instruction is transmitted over the microwave band to the user equipment to perform beamforming measurements of the beamforming signals. According to the beamforming measurements, the user equipment is switched to millimeter wave operation.

Abstract: In one embodiment, a method includes receiving, by a station (STA) from an access point (AP), a frame including a device type indicator and comparing the device type indicator with a device type accepted by a basic service set (BSS) of the AP to produce a comparison. The method also includes determining whether to associate the STA with the AP in accordance with the comparison, associating the STA with the AP upon determining to associate the STA with the AP, and not associating the STA with the AP upon determining not to associate the STA with the AP.

Abstract: Embodiments are provided herein for determining a synchronizing master for device-to-device (D2D) communication in a cellular network environment. In an embodiment, a user equipment (UE) receives a discovery signal comprising a timing reference, and determines a transmitter of the discovery signal. In accordance with the determination of the transmitter of the discovery signal, the UE performs one of synchronizing to the timing reference in the discovery signal and transmitting a second discovery signal. The UE performs the synchronizing to the timing reference if the transmitter of the discovery is a cellular network. Alternatively, the UE transmits the second discovery signal upon determining that the transmitter of the discovery signal is a second UE that is out of coverage of a cellular network.

Abstract: A method for channel reservation and communication using carrier sense multiple access (CSMA) with directional antennas in a wireless network. A source station (STA) may transmit a directional request to send (RTS) frame to a destination station before a data transmission. Upon receipt of the RTS frame, the destination STA may transmit a transmit network allocation vector (TNAV) frame instructing receiving stations not to perform transmissions toward the destination STA for a predefined period of time, which may include a channel quality measurement (CQM) period. The destination STA may transmit a directional clear-to-send (CTS) frame when channel quality estimated during the CQM meets a criterion. The source STA may then transmit a directional data transmission to the destination STA upon receipt of the CTS frame.
