Embodiment Construction
[0042] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. This embodiment is guided by the technical solution of the present invention to conduct actual practice verification, and at the same time provides detailed implementation methods and specific operation procedures, but the scope of protection of the present invention is not limited to the following examples.
[0043] In traditional radio resource management and allocation methods, considering that the optimization of system performance is mainly aimed at achieving the goal of maximizing system throughput or fairness, the realization of such goals is often accompanied by the consumption of the total radio resources of the system increase, the conceptual requirement of "green communication" cannot be met. Therefore, the present invention proposes an ene...

The invention relates to a high-energy-efficiency frequency power allocation method based on user experience quality, and belongs to the field of wireless communication technology. The method of the present invention aims at the problems of uneven performance in various aspects of multi-service and multi-user wireless communication systems and high energy consumption of the system, and optimizes the allocation of spectrum resources and power resources in the wireless communication system respectively. Based on the joint data rate proportional fairness algorithm and multi-objective optimization technology, the purpose of optimizing user QoE and user fairness is achieved while ensuring high energy efficiency of the system. At the same time, based on the final QoE size of users of different service types after wireless resource allocation is completed, the system determines the maximum service coverage area corresponding to the service. The allowable service ranges for different service types are different from each other, thus forming Amorphous coverage of the community.
Description
technical field [0001] The invention relates to a high-energy-efficiency frequency power allocation method based on user experience quality, and belongs to the technical field of wireless communication. Background technique [0002] With the increasing scale of mobile communication systems and the advent of the information age, all kinds of new multimedia information services emerge in an endless stream, and the contradiction between users' increasing requirements for information service performance and limited wireless system resources is also gradually expanding. Optimal allocation of resources becomes critical. In the research field of traditional wireless resource allocation technology, it is mainly to optimize a class of index parameters called Quality of Service (QoS), so as to effectively allocate wireless resources. The QoS indicator is a comprehensive performance of all business service levels that determine user satisfaction. It can be interpreted as a key perform...
