Example Embodiment

[0043] The present invention will be further described below in conjunction with specific examples, but the present invention is not limited to these specific embodiments. Those skilled in the art should realize that the present invention covers all alternatives, improvements and equivalents that may be included within the scope of the claims.

[0044] The selection of the scene directly affects the performance of the resource allocation method. The following is a detailed analysis of the scene setting and parameter selection.

[0045] 1 Classification and quantity of mobile terminals

[0046] In the D2D communication system, terminals include two categories: traditional cellular network mobile terminal CUE and D2D mobile terminal DUE. Among them, DUE appears in pairs, a pair of DUE includes D2D transmitting terminal DTUE and D2D mobile receiving terminal DRUE. In the FDD-LTE network, one subchannel CH is allocated to one CUE, and multiple DUE pairs can reuse the channel resources ...

Abstract

The invention relates to a 5G communication system resource allocation method based on an improved grey wolf optimization algorithm. The method comprises the following steps: firstly, initializing thebasic parameters of a system, initializing a grey wolf population identifying a resource allocation scheme according to a good point set principle, and calculating and sequencing fitness values of the grey wolf population by taking the minimum total interference of the system as a target function; secondly, selecting the wolves with the first three fitness values according to a sequencing result,and calculating the positions of the other wolves relative to the wolves with the first three fitness values; updating the positions of the other wolves, updating the positions of all wolves and calculating the fitness value of each wolf; and finally, determining whether the number of iterations reaches the set maximum number of iterations or not, and if the iterations are completed, obtaining anoptimal resource allocation strategy. According to the method, a solution space is increased through the good point set principle, an algorithm nonlinear convergence factor calculation mode is improved, an individual position updating equation is improved in combination with a fitness value, the total interference of the system is effectively reduced, then the D2D user access number of a cell isincreased, the system throughput is improved, and the method is easy to implement.

Description

technical field [0001] The present invention relates to the field of 5G communication, in particular to a resource allocation method of a 5G communication system based on an improved gray wolf optimization algorithm. Background technique [0002] The rapid development of wireless communication technology has now entered a communication era in which everything is intelligently interconnected. With the continuous increase of business types and demands, the current shortage of network spectrum resources needs to be solved urgently. The traditional cellular network system can no longer meet the needs of a large number of users. The "base station-centric" wireless network architecture requires the base station to participate in each communication link, resulting in excessive load pressure on the base station and low utilization of spectrum resources. Such as massive MIMO , 5G communication and other technologies came into being. As an important key technology of 5G communicatio...
