Abstract: A vehicle may transmit, to a network entity, a lane use request message associated with a lane for the vehicle. The network entity may identify lane information associated with a lane for a vehicle. The network entity may identify vehicle information associated with the vehicle. The network entity may transmit, to the vehicle, and the vehicle may receive, from the network entity, a lane use grant message based on at least one of the identified lane information or the identified vehicle information. The lane use grant message may be indicative of a permission for the vehicle to use the lane. The vehicle may not be permitted to use the lane without the permission. The lane may correspond to a flexible direction lane, an emergency lane, a road shoulder, an HOV lane, or a passing lane.

Abstract: The disclosure generally relates to synchronizing application account data using out-of-band device-to-device (D2D) communication between peer wireless devices. More particularly, a first device may generate a local unique expression that includes a name, one or more user credentials, and a last update time associated with an application registered for a D2D-based application synchronization service. In response to detecting one or more external unique expressions from one or more peer devices in proximity that match the name and the user credentials associated with the registered application, the first device may then identify, among the one or more peer devices, an update device associated with an external unique expression having a last update time more recent than the last update time associated with the local unique expression and request an update to synchronize the application account data associated with the registered application from the update device over an out-of-band D2D connection.

Abstract: Aspects presented herein may enable a roadside unit (RSU) or a set of RSUs to assist vehicles to control their headlights, such as switching between high beam(s) and low beam(s) or adjusting the brightness, intensity, and/or range of their headlight beam(s) to improve road safety. In one aspect, an RSU receives at least one of a first message that includes first information associated with a first vehicle or a second message that includes second information associated with a second vehicle. The RSU transmits, based on at least one of the first message or the second message, an indication to modify at least one of a first set of parameters associated with a first lighting system at the first vehicle or a second set of parameters associated with a second lighting system at the second vehicle.

Abstract: Techniques are provided for traffic intersection control information to vehicles via V2X communication links. An example method for providing traffic intersection control messages includes receiving vehicle information associated with a plurality of proximate vehicles, generating one or more vehicle groups based on the vehicle information, generating a traffic control plan based at least in part on the one or more vehicle groups, and transmitting one or more traffic intersection control messages to one or more of the plurality of proximate vehicles based at least in part on the traffic control plan.

Abstract: Method and apparatus for maintaining C-V2X timing (e.g., in platoon scenarios). The apparatus of a slave UE determines a thermal condition of the respective slave UE within a platoon of UEs. The apparatus performs synchronization with a first synchronization source, directly or indirectly, based on the thermal condition of the slave UE. Synchronization is performed directly with the first synchronization source in response to a determination that the thermal condition of the slave UE is below a threshold. Synchronization is performed indirectly with the first synchronization source through a master UE within the platoon of UEs in response to a determination that the thermal condition exceeds a threshold. The apparatus may receive, from a master UE within the platoon of UEs, SLSS to synchronize indirectly to the first synchronization source through the master UE.

Abstract: The disclosure generally relates to avoiding physical cell identifier (PCI) collision and confusion using LTE-Direct expressions. In particular, a small cell may discover LTE-Direct expressions that include PCIs associated with neighbor small cells and select (or reselect) a local PCI to ensure that the local PCI differs from the PCIs associated with each neighbor small cell. Furthermore, the small cell may detect PCI confusion where multiple neighbors broadcast LTE-Direct expressions with the same PCI and different E-UTRAN Cell Global Identifiers (eCGIs) and/or detect PCI confusion in neighbor small cells where the local PCI matches the PCI used in a neighbor's neighbor and the local eCGI used in the small differs from that used in the neighbor's neighbor. The small cell may additionally broadcast LTE-Direct expressions that include at least the local PCI and eCGI to enable neighbors to avoid PCI collision and confusion in the same manner.

Abstract translation: 本公开通常涉及使用LTE-Direct表达式来避免物理小区标识符（PCI）冲突和混淆。 特别地，小小区可以发现包括与相邻小小区相关联的PCI的LTE-Direct表达，并且选择（或重新选择）本地PCI以确保本地PCI与与每个相邻小小区相关联的PCI不同。 此外，小单元可以检测PCI混淆，其中多个邻居使用相同的PCI和不同的E-UTRAN小区全局标识符（eCGI）广播LTE-Direct表达和/或检测在本地PCI与所使用的PCI匹配的相邻小小区中的PCI混淆 在邻居邻居中使用的本地eCGI与邻居邻居中使用的eCGI不同。 小小区还可以广播至少包括本地PCI和eCGI的LTE-Direct表达，以使邻居以相同的方式避免PCI冲突和混淆。
