Method of resource selection where a selection window with a total number of resources is set. The method includes setting a sensing window and monitoring slots by decoding a physical sidelink control channel (PSCCH) and measuring a reference signal received power (RSRP), setting a threshold, excluding any restricted resources from the total number of resources, excluding any occupied resources from the total number of resources, and determining if an initial number of remaining resources is greater than or equal to an initial percentage of the total number of resources.

A method for operating a security system. The method includes: providing payload data and monitoring data on a backend device; transmitting the payload data via a first channel and transmitting the monitoring data via a second channel of an air interface to an apparatus device; wherein the payload data are transmitted to the apparatus device only when the monitoring data are cyclically received on the apparatus device.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for network risk assessment. One of the methods includes obtaining information describing network traffic between a plurality of network devices within a network. A network topology of the network is determined based on the information describing network traffic, with the network topology including nodes connected by an edge to one or more other nodes, and with each node being associated with one or more network devices. Indications of user access rights of users are associated to respective nodes included in the network topology. User interface data associated with the network topology is generated.

A wireless communication system for a ground based vehicle, such as a train, is disclosed. In an embodiment, the system includes a router connected to a plurality of antennas. The router is configured to transmit and receive a wireless data communication to and from a stationary communication server outside the ground based vehicle through at least one base station of an exterior mobile network via the plurality of antennas. The plurality of antennas are directional antennas arranged on planes of the vehicle functioning as ground planes, isolating planes, or absorbing planes. Each plane extends in a height direction or a length direction of the ground based vehicle. At least one antenna's beam covers a laterally directed sector to a first side of the vehicle, and at least one antenna's beam covers a laterally directed sector to a second side of the vehicle.

Disclosed are apparatuses and techniques for wireless communications. In an aspect, path information from a plurality of relays is received at a server. A relay cell list for an area of interest is compiled based on the received path information from the plurality of relays. The relay cell list is provided to a user equipment (UE). The UE can use the relay list to assist in the search and/or selection of relays in the wireless communications network.

The embodiments herein relate to a method and a network device for network slicing, the method comprising: receiving, from a terminal device, a request for at least one of reserving and assigning a network slice for an application; determining whether the application is previously known in terms of application profile or application identity; the determination being performed by matching against a plurality of application profiles and/or application identities residing in an application profile/identity database; if the application is determined to be known, providing a cost for setting up or for assigning a network slice for the application indicated in the request; and if the application is determined to be unknown, assigning a profile to the application and at least one of configuring and assigning a default network slice to the application.

Methods, apparatuses, and systems are disclosed for enhancing timing relationships in non-terrestrial networks (NTNs), e.g., by managing timing offset values and intelligently handling reporting failure relating to timing information reporting. To accommodate increased propagation delay in NTNs, a user equipment (UE) may supplement its timing advance (TA) value with component values representing roundtrip times to the satellite. The UE may maintain both open-loop and closed-loop portions of the TA value, and may report the TA value, or components thereof, to the network for timing synchronization. Methods and systems are also disclosed for failure handling in this reporting process.

A method of a base station in a mobile communication system is provided, which includes receiving position information of at least one UE; determining an initial position of a UAV based on the position information; transmitting, to the UAV, control information related to the initial position and association information between the at least one UE and the UAV; receiving, from the UAV, first feature information related to a communication state between the at least one UE and the UAV; and transmitting control information related to a movement position of the UAV based on an output of a reinforced learning network to which the first feature information is input.

Improved resource allocation approaches for sidelink communication are provided. In an aspect, a first wireless device may reserve a first resource for a sidelink communication and second resources for retransmissions, respectively, of the sidelink communication, and may transmit the sidelink communication using the first resource. In response to determining to release the second resources, the first wireless device may transmit, to a second wireless device, a release indication indicating that the second resources are available. In an aspect, a wireless device may receive a first sidelink communication from a transmitting wireless device on a first resource, and may identify second resources reserved respectively for retransmissions of the first sidelink communication. In response to a determination that the second resources are available for a second sidelink communication, the wireless device may report the second resources to a higher layer within the wireless device for resource selection.

A technique is directed to methods and systems for providing autonomous wireless coverage. In some implementations, the autonomous wireless coverage providing machine (e.g., a mobile wireless tower) can move to various locations to optimize coverage, connectivity, and/or quality. The mobile wireless tower can collect environment data of a location and determine the terrain and wireless devices requesting coverage. The mobile wireless tower can identify a location to provide network coverage to the devices based on the terrain. In some implementations, the mobile wireless tower can determine a location to provide coverage using Artificial Intelligence or Machine Learning retrieved from the network for which the mobile wireless tower provides coverage. The mobile wireless tower can have a flexible length wired or wireless backhaul capability for the mobile wireless tower to send data and retrieve data stored on the network.
