Abstract:
A system and method are provided for traffic signaling in wireless or sensor networks. The system and method use information or bits in a Signal Field (SIG) of Physical Layer (PHY) preamble in a packet to provide traffic control information. An embodiment method implemented by a network component comprises indicating a traffic direction and a traffic type for traffic control in a SIG in a frame and transmitting the frame including the SIG. Another method comprises receiving in a frame a SIG for traffic control that indicates a transmission type and decoding the SIG field to determine whether to process remaining information in the frame if the frame comprises data payload or a Media Access Control (MAC) header.
Abstract:
A method for transmitting to an access point includes receiving a selection condition and a selection contention period from the access point, and comparing the selection condition to a selection parameter. The method also includes contending for use of a transmission medium during the selection contention period if the selection parameter meets the selection condition.
Abstract:
A method performed by a first device is disclosed that includes sending a light of sight, LOS, determination request to a second device which communicates with the first device, wherein the LOS determination request includes an indication of a dual polarization procedure for Line of Sight (LOS), with the indication of the dual polarization procedure for LOS is used indicating that a same sequence of bits is sent at two polarizations to the same direction; a channel measurement for each of the two received sequences at the two polarizations is compared to determine whether a transmission between the first device and the second is LOS or NLOS.
Abstract:
Embodiments are provided for identifying transitory WiFi users and providing a differential treatment of such users in terms of delaying associating steps between user stations (STAs) and an access point (AP). A transitory user refers to a user or user device that connects to a WiFi AP but does not run applications that require association or assigning IP addresses, such as short-term or temporary connected WiFi users that are on the move. In an embodiment, a STA connects to an AP. Upon the STA indicating its transitory behavior to the AP or the AP detecting criteria of transitory behavior of the STA, the STA obtains a delay time value from the AP. The STA then delays sending an association request to the AP, or alternatively, the AP delays handling the association request from the STA in accordance with the delay time value.
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:
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.
Abstract:
A method for reducing authentication signaling in a wireless network includes identifying a plurality of access points in a network belonging to a group. An access request message is received from a first access point associated with a device being in range of the first access point. A determination is made whether the device has been authenticated within the group. A proxy accept message is sent to the to the first access point in response to the device being authenticated with the group without communicating with an authentication server for authentication of the device. A master access point may be used in performing the reduction of authentication signaling in the wireless network.
Abstract:
A method for multiple association includes associating with a first access point (AP) in a primary basic service set (BSS), associating with a second AP in a secondary BSS, informing the first and second APs of an inter-BSS relaying capability of a doubly-associated station, and relaying data between the first AP and the second 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.
