Abstract

The invention discloses a method and device for a user to adaptively connect with a base station for communication, a medium and equipment, and the method comprises the following steps: constructing a network topology which comprises a macro cellular base station, a plurality of small cellular base stations and a plurality of users; setting a communication condition of the user; under the condition, calculating the rate of the user in uplink transmission; solving a mode for the user to connect the base station with the maximum energy efficiency by taking the user as the center, constructing an energy efficiency maximization calculation model, and calculating a connection mode matrix according to the maximization calculation model; constructing a constraint model; and substituting the connection mode matrix into the constraint model, and solving an optimal resource allocation scheme taking the user as the center. A user selects an optimal connection mode through maximization of energy efficiency, and the total cost consumed by the user is optimized to the maximum extent by determining a mode for connection with the base station through the user, and the total cost comprises power consumption consumed by the user in uplink transmission and bandwidth allocation.

Description

technical field [0001] The invention belongs to the technical field of resource allocation, and in particular relates to a method, device, medium and equipment for a user to adaptively connect to a base station for communication. Background technique [0002] With the rapid development of the new generation of wireless communication technology, the innovation and progress of science and technology, medical care, education and other industries have also ushered in new opportunities, but this has also increased the network traffic burden and the demand for network quality. The development of network communication brings great challenges. The current wireless communication network is facing many problems, among which the security problem has always been the most direct problem faced by researchers and technicians. Information leakage and data loss often happen around us. At the same time, with the exhaustion of various limited resources, technicians must also consider the issu...
