Abstract: A method for vehicle-to-everything (V2X) communication in a wireless network is provided. The method includes transmitting, by a base station, a resource grant message to a first user equipment (UE), the resource grant message identifying available resources for V2X communication by the first UE. The method further includes receiving, by the base station, a feedback report from a second UE, the feedback report indicating a quality of the V2X communication by the first UE.

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: The hidden node problem can be avoided by scheduling stations in different sectors to perform transmissions during different time periods. Sectorized scheduling can be communicated to stations through transmission of beamformed beacon signals at the beginning of respective time periods. For instance, a first beamformed beacon signal may be transmitted to stations in a first sector at the beginning of a first time period, while a second beamformed beacon signal may be transmitted to stations in a second sector at the beginning of a second time period.

Abstract: A system and method of ANQP querying using a common ANQP group version. One embodiment of the method includes associating an original common ANQP group version with a common ANQP group, transmitting a message containing the original common ANQP group version to at least one station, associating a new common ANQP group version with the common ANQP group when an element therein is changed, and transmitting another message containing the new common ANQP group version to the at least one station.

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: A physical downlink shared channel (PDSCH) region of a subframe may include a reference signal (RS) section that includes one or more of a beam-scanning subsection, a transmit (TX) beam-tracking subsection, a receive (RX) beam-tracking subsection, and a channel state information (CSI) subsection. Reference signals in the TX beam-tracking subsection may be used to update TX analog beams. Reference signals in the RX beam-tracking subsection may be used to update RX analog beams. Reference signals in the beam-scanning subsection may be used to evaluate different combinations of TX and RX analog beams for use in a future directional data transmission. Reference signals in the CSI subsection may be transmitted over quasi-co-located (QCL) antenna ports, and may be used for purposes of channel estimation.

Abstract: An extension to the Access Network Query Protocol (ANQP) protocol allows stations (STAs) to discover multiple APs via a single ANQP request/response exchange. A STA can send a single ANQP request message to request information for multiple APs, e.g., two or more neighboring APs. The receiving AP may retrieve discovery information for one or more neighboring APs, and send an AP response message including the retrieved discovery information to the requesting STA. The ANQP request message identify the multiple APs for which discovery information is sought, and may specify which information is being requested for that corresponding AP.
