The application discloses a communication method, device, base station, movable relay and storage medium, and relates to the field of wireless communication. The specific implementation scheme is as follows: a base station acquires a first position where a movable relay is located and a second position where a terminal is located, and the terminal receives data from the base station through the movable relay; according to the energy efficiency of the movable relay, the first position of the movable relay and the second position of the terminal, the planning path information of the movable relay is determined, and the planning path information is sent to the movable relay. Therefore, the base station can determine the planning path information of the movable relay according to the energy efficiency of the movable relay, the position where the movable relay is located and the position where the terminal is located. Since the path planning information is determined in combination with the energy efficiency of the movable relay, the energy efficiency state of the movable relay can be fully considered, so that the movable relay moves according to the planning path information, the energy efficiency of the movable relay can be improved, and the communication service time of the movable relay can be prolonged.

This invention belongs to the field of mobile communication technology and discloses a service flow scheduling method for high-speed rail millimeter-wave communication scenarios assisted by unmanned aerial vehicles (UAVs). By configuring system parameters such as node location and link parameters, it acquires information such as mobile relay location, candidate link status, and service requirements in real time. It calculates the propagation distance based on the node and mobile relay locations, and uses link parameters to obtain the average load per time slot within a frame. Then, it calculates the minimum number of time slots required for each mobile relay to complete the service through candidate links. Links exceeding the remaining budget of the resource pool are then eliminated to form a feasible candidate set. This scheme can accurately select effective links, avoid resource conflicts and underutilization, and ensure reasonable resource allocation. Based on a scoring system, it selects the optimal link and dynamically updates the candidate set, taking into account both service priority and starvation status. This avoids the problem of high-priority services being squeezed out and weak link services being starved. Furthermore, frame-level cyclic scheduling reduces algorithm complexity and meets the real-time scheduling requirements of high-speed rail scenarios.
