Non-orthogonal multiple access network resource allocation method

Abstract

The invention provides a non-orthogonal multiple access network resource allocation method, which is used to solve the problem of the prior art of lack of non-orthogonal multiple access network resource allocation mechanisms having strong feasibility. The non-orthogonal multiple access network resource allocation method comprises steps that various parameters are initialized, and a two-sided matching algorithm is used to solve a problem of associating a user and a channel; by adopting a Lyapunov optimization algorithm, an optimal solution of power allocation is acquired; by adopting iterativejoint user channel matching and power allocation algorithm, energy efficiency and economic benefits can be improved to the greatest extent, and at the same time, individual rationality and authenticity attribute are guaranteed. The reasonable allocation of NOMA network resources can be realized, and at the same time, maximization of economic benefits and energy effectiveness of content providers can be guaranteed, and therefore the energy efficiency can be improved to the greatest extent, a system capability is improved, and under a precondition of not reducing service quality and consideringan energy problem, an increasing data requirement is satisfied, and sustainable development is realized.

Description

technical field [0001] The invention belongs to the field of mobile communication, and in particular relates to a non-orthogonal multiple access network resource allocation method. Background technique [0002] In the future, the total number of devices connected to the global mobile communication network will reach 100 billion. The volume of communication traffic on the Internet will increase rapidly, and the mobile data traffic will experience explosive growth, which will make network energy consumption, deployment and maintenance more and more complex. Now Some orthogonal multiple access technologies are difficult to efficiently cope with future thousand-fold business traffic growth and massive device connections, and cannot intelligently meet the trend of diversification of future user and business needs. In order to better solve this problem, which can meet the mobile service rate requirements and improve spectrum efficiency, non-orthogonal multiple access technology (N...
