A first on-board terminal for radio communication in a radio network. The first on-board terminal is designed to retransmit first data via the radio channel after the expiration of a second time period, which begins after the end of the previous transmission of the first data, if the radio channel is not occupied after the expiration of a first time period.

A communication system is provided, including: an acquiring unit for acquiring quality information on a wireless communication quality between a wireless base station and a movable mobile relaying apparatus that relays communications between the wireless base station and wireless communication terminals; and a transmitting unit for transmitting the quality information to the wireless communication terminals. In addition, an information processing method performed by a computer is provided, the method including: acquiring quality information on a wireless communication quality between a wireless base station and a movable mobile relaying apparatus that relays communications between the wireless base station and wireless communication terminals; and transmitting the quality information to the wireless communication terminals.

A method for the assisted driving of a vehicle. A setpoint trajectory for the vehicle to be followed in a parking facility being ascertained as a function of a type of the vehicle. The ascertained setpoint trajectory is transmitted to the vehicle via a communication network. A digital map of the parking facility is transmitted to the vehicle via the communication network. The vehicle may autonomously drive in the parking facility based on the setpoint trajectory and the digital map. Additionally, the vehicle may be monitored with the aid of a vehicle-external monitoring system while it is driving autonomously in the parking facility. A device for the assisted driving of a vehicle, a method and a device for operating a vehicle, a parking system for vehicles, a vehicle, and a computer program, are also described.

A wireless communication system for a train, including: a plurality of antennas arranged on an exterior side of the train; an internal local area network (LAN) inside the train; and at least one router in the train for receiving and transmitting wireless voice communication and data communication to and from a stationary communication server outside the train via the antennas, through at least one exterior mobile network, the at least one exterior mobile network providing at least two concurrently useable data links. The internal LAN provides WiFi communication between the at least one router and at least one mobile terminal located inside the train. Further, the router is arranged to transfer wireless voice communication via voice over WiFi (VoWIFI) between the at least one mobile terminal and the exterior mobile network.

A short range wireless communication (SRWC) system for a vehicle and a method of using the SRWC system. The system includes a first SRWC node in the vehicle having a SRWC receiver and a SRWC transmitter, and a second SRWC node in the vehicle adapted to send and receive SRWC data. The first and second SRWC nodes are configured so that when the first and second SRWC nodes are operable, an SRWC object device perceives the first and second SRWC nodes as a single SRWC device.

A network for providing high speed data communications may include multiple terrestrial transmission stations that are located within overlapping communications range and a mobile receiver station. The terrestrial transmission stations provide a continuous and uninterrupted high speed data communications link with the mobile receiver station employing a wireless radio access network protocol.

Examples described herein include systems and methods which include wireless devices and systems with examples of an autocorrelation calculator. An electronic device including an autocorrelation calculator may be configured to calculate an autocorrelation matrix including an autocorrelation of symbols indicative of a first narrowband Internet of Things (IoT) transmission and a second narrowband IoT transmission. The electronic device may calculate the autocorrelation matrix based on a stored autocorrelation matrix and the autocorrelation of symbols indicative of the first narrowband IoT transmission and symbols indicative of the second narrowband IoT transmission. The stored autocorrelation matrix may represent another received signal at a different time period than a time period of the first and second narrowband IoT transmission. Examples of the systems and methods may facilitate the processing of data for wireless and may utilize less memory space than a device than a scheme that stores and calculates autocorrelation from a large dataset computed from various time points.

A method for gateway relocation, an MME and a DeNB are disclosed. The method includes: in a process of an MRN performing handover of the DeNB, the MME of the MRN judging whether it is required to execute a relocation of a gateway serving the MRN according to the current location of the MRN.

There is provided a wireless base station including a connection establishment unit configured to establish a communication connection with a wireless communication device, and a connection control unit configured to control in a manner that, in a case where the wireless communication device is a wireless relay device having a relay function for relaying a communication between the wireless base station and a communication terminal, a connection with the wireless communication device is not released even when a time during which a communication is not performed with the wireless communication device has passed a first time, and in a case where the wireless communication device is not the wireless relay device, the connection with the wireless communication device is released in response to a state where the time during which the communication is not performed with the wireless communication device has passed the first time.

A wireless communication system using cells to provide wireless access to services, comprising a first base station installed on board a public transportation vehicle to provide a moving cell, and a second base station installed at a stop at which users enter or leave the vehicle, to provide a fixed cell. A central controller guides handovers of users entering or leaving the vehicle. The first and second base stations to provide data concerning users to the central controller, and the central controller, over many journeys of the vehicle, gathers profile data of users based on the data provided by the base stations. As the vehicle approaches a stop, the central controller makes predictions about users likely to enter and leave the vehicle, and, provides guidance to the first and second base stations for performing handovers.
