A method for resource allocation in uav-assisted ultra-reliable low-latency communication

Abstract

This application provides a resource allocation method in UAV-assisted ultra-reliable low-latency communication, relating to the field of wireless communication technology. The method includes: acquiring a global state vector of a UAV-assisted ultra-reliable low-latency communication network; the global state vector representing the position information, remaining energy state, and channel gain information between each UAV and ground users in the UAV-assisted ultra-reliable low-latency communication network; extracting cross-UAV state coupling features from the global state vector through a multi-head self-attention layer in a trained policy network; determining a joint action strategy based on the state coupling features; the joint action strategy including UAV flight control parameters and ground user transmit power control parameters; and adjusting the flight state of each UAV and the transmit power of each ground user based on the joint action strategy to complete resource allocation. This method is used for precise joint optimization of UAV flight trajectories and ground user transmit power.
