A vehicle routing evaluation system makes predictions about network performance data along road segments relevant to navigation of a vehicle and generates routing instructions or recommendations based in part on the network performance data. The vehicle routing evaluation system may send control signals to automatically control navigation of the vehicle to follow the routing generated routing or may present the navigation instructions to a teleoperator that controls the vehicle. Alternatively, the vehicle routing evaluation system generates a display with a navigational map overlay providing visual cues indicative of predicted wireless performance along various road segments to enable the teleoperator to select between possible routes.

A base station that includes a memory for storing computer readable code and a processor operatively coupled to the memory is provided herein. The processor is configured to transmit, to a terminal apparatus, information associated with communication delays predicted for communication between the base station and the terminal apparatus. The terminal apparatus acquires the information associated with the communication delays from the base station.

Deviations of signal strengths in a first frequency band from signal strengths in at least one second frequency band are predicted based on a trained machine-learning model (350′). At least one source signal strength map is obtained. The at least one source signal strength map describes signal strengths in the at least one second frequency band for a coverage area of the wireless communication network. Based on the at least one source signal strength map and the predicted deviations of signal strengths, at least one target signal strength map describing signal propagation in the first frequency band for the coverage area is determined.

The present disclosure relates to relay communication based on a sidelink in a wireless communication system, and a method for operating a first terminal may include performing direct communication with a second terminal based on a sidelink, when a path between the first terminal and the second terminal is predicted to be blocked and another relay device providing a relay service is discovered, transmitting, to the relay device, a first message for requesting the relay service for the first terminal and the second terminal, receiving, from the relay device, a second message for accepting the request for the relay service, and performing relay communication with the second terminal, and the first message may include information on the second terminal.

A processor-implemented method is presented. The method includes receiving an input sequence comprising a group of channel dynamics observations for a wireless communication channel. Each channel dynamics observation may correspond to a timing of a group of timings. The method also includes determining, via a recurrent neural network (RNN), a residual at each of the group of timings based on the group of channel dynamics observations. The method further includes updating Kalman filter (KF) parameters based on the residual and estimating, via the KF, a channel state based on the updated KF parameters.
