Systems and methods for correlating wireless communication performance with vehicle system configurations determine wireless message characteristics of wireless messages communicated between vehicles in vehicle systems and locations along a route where the wireless message characteristics were determined. The wireless message characteristics and the locations can be determined during movement of the vehicle systems along a route. Relative positions of the vehicles in the vehicle systems is obtained, and a signal propagation profile is determined based on the wireless message characteristics, the locations where the wireless message characteristics were determined, and the relative positions of the vehicles. The signal propagation profile can represent relationships between the wireless message characteristics, the relative positions of the vehicles, and the locations along the route. This profile can be used to control movement and/or communication of other rail vehicle systems, to generate trip plans for other vehicle systems, to diagnose communication faults, and the like.

Dynamic tuning of mobile network device configuration based on location is described. An example of a storage medium includes instructions for switching a mobile network device in a vehicle to a maintenance mode based at least in part on detection of a first location, the first location being a maintenance hub location; enabling administrative communications and disabling user communications for the mobile network device in the maintenance mode; receiving configuration data for the mobile network device from an external server in the maintenance mode, the configuration data being based at least in part on a route for the vehicle; switching the mobile network device to a service mode based at least in part on detection of a second location that is different than the first location; and enabling service communications and disabling administrative communications for the mobile network device in the service mode.

A method and an apparatus for cell selection or reselection and a method and an apparatus for setting a cell handover parameter are provided. The method for cell selection or reselection includes: acquiring speed priorities of one or more cells and a movement speed grade of a terminal device; and performing cell selection or cell reselection according to the speed priorities and the movement speed grade. According to the embodiments of the present disclosure, the terminal device acquires speed priorities of network cells and its own movement speed grade, so as to firstly perform a cell filtering by using the speed priority and then perform another cell filtering by using a frequency priority during the cell selection to select a target cell to camp on, to enable the terminal device to distinguish between cells with different speed priorities and preferentially camp on a cell matching a movement speed of the terminal device, so that the terminal device camps on cells more efficiently and cells with different priorities serve the terminal device more efficiently.

Methods, systems, and devices for wireless communication are described. A 5G device may decode a control channel transmission of a safety message in a vehicle-to-everything system during a first portion of a time period. The 5G device may identify, based at least in part on the decoding, a pool of resource blocks (RBs) that are available for the time period. The 5G device may select a subset of RBs from the available pool of RBs for a transmission during a second portion of the time period.

In a mobile communication system using a mobile-type radio relay apparatus that forms a plurality of cells toward the ground or the sea while moving in an upper airspace, a deterioration in communication quality, which is caused by a Doppler shift of a reception signal due to a relative movement of a radio relay apparatus with respect to a terminal apparatus of each of a plurality of cells or a feeder station on the ground or on the sea, is suppressed. The communication system comprises a mobile-type radio relay apparatus that is disposed movably by flying in an upper airspace, forms a plurality of cells from an antenna at a predetermined altitude toward the ground or the sea, and performs a radio communication with a terminal apparatus located in each of the plurality of cells. The communication system comprises an estimation section for estimating a Doppler shift in at least one of a radio communication of a service link between the terminal apparatus located in the cell and the radio relay apparatus and a radio communication of a feeder link between the radio relay apparatus and a feeder station on the ground or on the sea, and a correction section for correcting a frequency of the at least one radio communication based on an estimation result of the Doppler shift.

An ultrawideband radio transceiver/repeater provides a low cost infrastructure solution that merges wireless and wired network devices while providing connection to the plant, flexible repeater capabilities, network security, traffic monitoring and provisioning, and traffic flow control for wired and wireless connectivity of devices or networks. The ultrawideband radio transceiver/repeater can be implemented in discrete, integrated, distributed or embedded forms.

An embodiment of the present disclosure provides a method for obtaining a Vehicle to Everything Policy (V2XP). The method includes: transmitting, by a terminal device, at least one of first information and second information to a Policy Control Function (PCF), the first information being used for requesting a configuration of a policy for V2X communication over a PC5 interface, and the second information being used for requesting a configuration of a policy for V2X communication over a Uu interface; and receiving, by the terminal device from the PCF, at least one of the policy corresponding to the first information and the policy corresponding to the second information.

Multiple mobile cellular network (MCN) communication systems can be networked together to form a network of MCN communication systems (NOM). Each MCN communication system within the NOM can operate as an independent cellular network to provide communications between user equipment within a covered area. When a UE in one MCN of the NOM moves into a different MCN of the NOM, the corresponding MCN communication systems can handover the UE. The UE can also be handed over between MCN communication systems when the MCN communication systems move.

A system and method for micro-navigation of a mobile object (1000) is disclosed herein. Micro-navigation provides guidance to destinations that are not normally found on maps or in navigation systems. In one micro-navigation method, data is collected (1501) related to route transit to specific end points that are not typically mapped. The end points are identified (1502) by relating specific geo coordinates, or physical landmark based characteristics, or electronically described and defined end point to a an identification that will be entered and stored in a location database. Guidance (1503) is provided to vehicles traveling to those end points or destinations, with additional information relevant to a route and/or a specific vehicle and configuration updated and made available to the system.

A connected car and an onboard user equipment (UE) may establish independent cellular connections and may also establish a connection between each other. The UE establishes a first cellular link between the UE and a first network, establishes a connection with a connected car, wherein the connected car has a second cellular link between the connected car and a second network, evaluates one or more conditions and declares one of the first cellular link or the connection with the connected car a primary network interface for the UE based on, at least, the one or more conditions.
