最近做了很多关于测量报告的文档,其中有个说法让我很是纠结,就是不大清楚到底是Ec/N0还是Ec/No。我查了一些资料,虽然都说是noise,但是不知道为什么是数字0,而不是小写字母o。
为此,我去搜了下Ericsson,结果发现只有数字0的写法,而且可怜的是居然只有3个hits,去找了下Cisco,发现别个用的是EC/NO,去找3GPP,发现两个都有,hits也差不太多。
这下我可犯难了,如果是数字0的话,后面也没有1,2,3啥的,如果是o的话可以理解,是缩写,可是我去查了一个MR,发现脚本里却还真的是Ec/N0,这让我咋办?
大家看到的给个见解哈,谢咯~
3GPP协议里边是两个都有,好不清楚啊!
下边取自协议里边,关于S准则的:
Qmeas :
Quality value. The quality value of the received signal derived from the averaged CPICH Ec/No or CPICH RSCP for FDD cells, from the averaged P-CCPCH RSCP for TDD cells and from the averaged received signal level for GSM cells.
Qqualmeas:
Measured cell quality value. The quality of the received signal expressed in CPICH Ec/N0 (dB) for FDD cells. CPICH Ec/N0 shall be averaged as specified in [10].
Applicable only for FDD cells.
