准备用syetemview做一个EPA信道，发现systemview里面和3GPP相关的信道有两个，分别取自标准36.104和36.814.其中36.104的信道我很清楚，这个36.814是什么呢？摘录以下几句话：
The IMT-Advanced channel model for the evaluation of IMT-Advanced candidate RITs consists of a Primary Module and an Extension Module. In this part, only the primary module is included, which is mandatory for IMT-Advanced evaluation. The Primary Module covers the mathematical framework, which is called generic model, a set of parameters as well as path loss models.
The generic channel model is a double-directional geometry-based stochastic model. It is a system level[1] model in the sense that is employed, e.g., in the SCM model [B1].
清楚了，原来是系统级仿真的信道，类似SCM，在这里我们称作Primary Module或者generic model。
关于SCM搜索了下，有以下两篇参考：

[1] The term system-level means here that the model is able to cover multiple links, cells and terminals.
