摘要
TD-MBMS作为TD-SCDMA技术发展的一个重要里程碑,其标准正在不断演进中,由于采用了宏分集技术、单频网(SFN)、随机相位偏转、同步技术等一系列新型关键技术,为网络规划带来了很多新特点。本文就TD-MBMS的技术演进、网络规划出现的一些新内容作简要介绍。
TD-MBMS, the landmark technology of TD-SCDMA, is under continuous development. The novel key technologies such as macro-Rake, SFN. random phase shift, synchronization technology, etc, are adopted step by step, which result in many new features on wireless network planning. The evolution of TD-MBMS standards and the new performances on network planning are introduced in this paper.
