基于CoMP系统小区频谱划分新方案
首发时间:2013-01-18
摘要:随着无线接入技术的快速发展,第三代合作伙伴(3GPP)逐渐展开面向4G的研究工作并以独立成员的身份向国际电信联盟(ITU)提交了面向4G技术的LTE-Advanced(LTE-A)技术方案。其中,协调多点传输技术(CoMP)被认为是LTE-Advanced系统里的一个有效的提高边缘用户通信质量和改善小区平均吞吐量的方法。本文基于Comp-SU-MIMO下行系统,在CoMP频带资源分配上提出了基于用户QOS反馈的动态频谱划分方案,有效地提高频谱利用效率和边缘用户的吞吐量,在新的调度算法上也有新的改进。本论文对于3GPP在CoMP技术上的讨论有较之超前的参考意义。

A NOVEL FREQUENCE DIVISION SCHEME for COMP-SU-MIMO IN LTE-A DOWNLINK SYSTEM
Abstract:The coordinated multi-point transmission for single-user multi-input multi-output (CoMP-SU-MIMO) is considered as an effective approach for inter-cell interference coordination (ICIC) in LTE-A, which can effectively reduce inter-cell interference and improve cell average throughputs. The paper involves in the LTE downlink system based on the technology of coordinated multi-point transmission (CoMP). It concerns two aspects; one is a new dynamic algorithm of downlink frequency division, which can adjust the frequency band in time leading to increasing the band utilization rate and cell throughputs.
Keywords: Wireless Communication CoMP-SU-MIMO Spectrum Resource Throughput
