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 communication system and method for supporting a plurality of vehicle-to-everything radio access technologies (V2X RATs) is provided. The communication system configured to support multiple V2X RATs transmits, using a first V2X RAT, an indication of its availability to support an interworking function between the plurality of V2X RATs. The communication system receives an instruction to provide the interworking function between different V2X RATs. The interworking function may be incorporated in a vehicle that is joined to a platoon configured to use a first V2X RAT, and provide the interworking function between the first and a second V2X RAT. The interworking function may be used to add further vehicles to the platoon that communicate using only the second V2X RAT.

The present disclosure relates to a wireless communication device and a wireless communication method. The wireless communication device according to one embodiment comprises one or more processors, wherein the processor(s) is/are configured to acquire the type of information to be transmitted via device-to-device communication, wherein the type is one of a plurality of types at least including a first type and a second type; and the processor(s) is/are also configured to determine a resource use manner and a power control manner which are used for transmitting information at least according to the type of the information.

Disclosed in the present invention are a permanent-magnet magnetic levitation rail transit control system and method based on 5G communication technology. The system comprises: an intelligent control center, a 5G communication platform, a train security system, an Internet of things monitoring system, and a passenger service system. In the present invention, targeted at the problem of being difficult to ensure barrier-free transmission of signals even by means of beamforming technology due to high moving speed of a permanent-magnet magnetic levitation rail transit system and small coverage of 5G base stations, a multi-connectivity scheme is used, and the intelligent control center selects two 5G base stations for signal transmission at the same time depending on distribution of 5G base stations along a line, wherein one 5G base station is the current closest base station, and the other 5G base station is the next base station to be approached. By means of a relay-type base station passing mode, it is ensured that a 5G communication platform can provide a stable and reliable communication link.

There is provided a management apparatus configured to allocate a plurality of zones capable of identifying a three-dimensional space in common among a plurality of mobile communication carrier networks to a flight airspace allowing a plurality of mobile terminals to be flown, the plurality of mobile terminals being configured to respectively perform wireless communication with the plurality of mobile communication carrier networks, and configured to transmit information on allocation of the plurality of zones to a mobile communication network respectively managed by the plurality of mobile communication carriers.

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.
