Energy efficiency optimization and resource allocation method and system

Abstract

The invention provides an energy efficiency optimization and resource allocation method. The method comprises the following steps: calculating a signal-to-interference-noise ratio received by users ofan authorized spectrum in a small base station on a subchannel; calculating a signal-to-interference-noise ratio received by users of an unauthorized spectrum in the small base station on the subchannel; calculating the total capacity of all users in the small base station according to the capacities of the users of the small base station; calculating a utility function; rewriting an equivalent objective function; rewriting an optimization problem according to a defined throughput function and the average throughput of the users; rewriting the optimization problem again according to the arrival of traffic of the users in the small base station; and getting a solution of three sub-problems by means of Lyapunov optimization. The invention also provides an energy efficiency optimization andresource allocation system. Through the technical scheme provided by the invention, the enhancement of utility performance and the balance of energy efficiency delay can be realized under various constraints.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and system for energy efficiency optimization and resource allocation. Background technique [0002] According to the latest report of Cisco Visual Networking Index (VNI) Global Mobile Data Traffic Forecast, 70% of the world's population will become mobile Internet users in 2020 and own 1.5 Internet products per capita, while smart devices, mobile video and 4G networks will Growth will drive an eight-fold increase in mobile data traffic in the next five years. The development potential contained in this has brought unprecedented challenges to the communication industry. The current wireless communication technology is close to the limit in spectrum efficiency. Long Term Evolution (Long Term Evolution, LTE) licensed spectrum resources are already very crowded. [0003] In order to further improve the utilization of spectrum resources, it may be considered to use unlic...
