摘要
超3G在ITU-R范围内的各项研究工作还刚刚开始,基本上还处于制定工作计划的阶段。但目前关于对超3G频率需求计算方法的研究,已经有一些国家提出了自己的建设,主要是日本和德国。超3G研究工作,特别是频谱计算、业务预测、新的无线接入和核心网技术方面研究工作的开展,对我国的研究机构、相关公司和高校都是一个继续赶超世界先进通信技术,获取成果的绝好机会。
Research work on System beyond IMT-2000 in ITU-R has just started and is at the stage of planning. However, some countries, such as Japan and Germany, have put forward their own suggestions about the research on frequency retirements of System beyond IMT -2000. Research on System beyond IMT-2000, especially the research on spectrum calculation, service forecast, new wireless access and core network technology, will be a good opportunity for research organizations, related companies and colleges in China to go on overtaking global advanced telecom technologies and obtain achievements .
