Ec/N0 还是Ec/No?

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.
