摘要

针对超密集网络中移动用户的干扰管理和资源分配问题

提出了一种基于用户路径的资源预留算法

该算法首先以用户从起点到终点的最短路径为度量

进行一个最优路径的选择

在最优路径的选择过程中

考虑了用户必须经过的街区和不可能经过的街区;然后提出一种基于最优路径的资源预留和资源复用算法

该算法首先设计资源分配和资源预留的步骤

然后再针对所有用户进行资源复用的计算

以提高频谱资源的利用率。仿真结果表明

所提算法可以在用户移动的过程中

在保障用户较低掉话率的基础上

减小Femtocell基站间的干扰并提升系统性能。

Abstract

Aiming to the problem of interference management and resource allocation for mobile users in an ultra-dense network

a User Path based Resource Reservation（UPRR）algorithm is proposed in this paper.The scheme firstly takes the shortest path from the starting point to the end point as the metric to select an optimal path.In the selection process of the optimal path

this paper considers the condition that whether the blocks permit users pass through or not.Next the algorithm of resource reservation and resource reuse based on the optimal path is put forward

which firstly designs the steps of resource allocation and reservation

and then computes the resource reuse for all users in order to improve the utilization of spectrum resources.The simulation results show that the proposed algorithm can reduce the interference in the Femtocell Base Station（FBS）and improve the system performance on the basis of guaranteeing the low outage probability for mobile users.
