1. A device for predicting radio link performance, comprising:
communication circuitry; and
processing circuitry to:
receive, via the communication circuitry, a link performance prediction (LPP) request from a requesting entity, wherein the LPP request is a request to predict a performance of a radio link between a mobile device and a base station during a future time window;
determine a current path of the mobile device, wherein the current path is determined based on radio signals between the mobile device and the base station, and wherein the current path indicates a sequence of positions of the mobile device over a current time window;
predict, based on the current path, a future path of the mobile device, wherein the future path indicates a sequence of predicted future positions of the mobile device over the future time window;
generate a link performance prediction (LPP) response for the mobile device based on the future path and a base station coverage map, wherein:
the base station coverage map indicates a radio signal quality across a base station coverage area of the base station, wherein the base station coverage area is represented in a three-dimensional (3D) coordinate space, wherein a plurality of 3D regions within the base station coverage area are represented as a plurality of points within the 3D coordinate space; and
the LPP response indicates a predicted performance of the radio link between the mobile device and the base station during the future time window; and
send, via the communication circuitry, the LPP response to the requesting entity.
