作者: 天堂枫叶     标题: 5G 载波聚合

3GPP为5G（NR)网络就载波聚合在38.101-1和38.101-2分别定义了FR1和FR2的标准；在38.101-3定义了FR1与FR2之间的载波聚合；FR1载波聚合分为频段内连续，非连续；频段间；2载波，3载波，4载波载波聚合；[url=]整理：[/url][url=]kangguoying20200825[/url]
1.载波聚合等级
      在5G(NR)网络中载波聚合共分为12个等级，带宽最高达400M,最大支持8个载波的聚合；具体见下表：[url=]：[/url]
NR  CA bandwidth class/聚合等级

Note 1 : BWChannel,max is maximum channel bandwidth   supported among all bands in a release

Note 2 : It is mandatory for a UE to be   able to fallback to lower order NR CA bandwidth class configuration within a   fallback group. It is not mandatory for a UE to be able to fallback to lower   order NR CA bandwidth class configuration that belong to a different fallback   group

2.带内连续载波聚合（Intra-band contiguous CA）
    带内连续载波聚合（Intra-band contiguous CA）它是在一个频段内（如 n41)频点连续的多小区之间载波聚合；
