载波聚合下具有用户优先级的频谱接入方案研究

Research on Spectrum Access Scheme with User Priority under Carrier Aggregation

载波聚合技术是解决系统带宽不足与用户吞吐量低等问题的有效方案之一。本文分析了现有载波聚合下网络接入机制的特点,在此基础上考虑用户的多元化个性化需求提出了具有用户优先级的载波聚合资源分配方案。该方案在保障宽带用户最低服务质量的前提下达到切换用户的及时接入,以此来满足不同优先级用户的业务需求。

Carrier aggregation technology is one of the effective solutions to solve the problems of insufficient system bandwidth and low user throughput.In this paper,we analyze the characteristics of existing network access mechanisms under carrier aggregation,and propose a carrier aggregation resource allocation scheme with user priorities based on the diversified and personalized needs of users.The scheme achieves timely access for switching users while guaranteeing the minimum quality of service for broadband users,so as to meet the service requirements of users with different priorities.
