当前R15/R16承前启后状态

3GPP已经在2018.3发布了NSA的whole version ASN，并在2018.6发布了号称SA的整体规范文本，但是需要到2018.9发布SA的ASN. 这也就意味着R15的大部分内容即将完成并接近完整冻结。下一个努力的目标自然就是5G演进的R16版本。这里汇总了R15/R16部分版本信息 ，并转载了3GPP RAN WG主席近日演讲的一个slides，描述了R15和R16的承前启后的状态。大家参考下吧!

先回顾下3GPP各个版本的历史轨迹：

附上当前R16的feature list，这个list随着规范的演进也会不断丰富更新的，各条feature详细的信息参考如下链接：
