This invention discloses a method for optimizing resources in a
drone-assisted, self-free, large-scale
MIMO system. In a
drone-assisted, self-free, large-scale
MIMO system scenario, drones act as aerial access points, coordinating with ground access points to provide services to ground users. The specific design of this method includes designing user scheduling rules based on the coordinated
service provision of aerial and ground access points; designing a communication model in which aerial and ground access points cooperate to provide services according to the scheduling rules; designing a fair
resource allocation scheme including a user scheduling scheme, a
drone positioning scheme, and a power allocation scheme to users; maximizing the minimum downlink speed for users in the above communication model; and finally, verifying the feasibility of the proposed utility model by optimization methods such as block
coordinate descent and continuous convex optimization techniques. This invention can propose an optimal
resource allocation strategy, including drones, depending on the
current distribution of users and ground resources, achieving
blind spot coverage for providing services to ground users.
