Render
在执行 render 的时候,会将所有的数组抽成扁平,flat 会认为,children 就只有 Text 节点和 _Elememt 节点,相对来说,抽成扁平,在性能上也会得到提升。
为了能精确定位到更新的元素,在 Component 的原型上附加了类型为 symbol 的 _key,用来唯一标识一个组件
不必关心节点的 key, flat 在初次解析的时候,附加了 component 的 key,key 用了 Symbol 类型,为了
5G NR PMI码本设计方案。NR defines two types of CSI that differ in the structure and size of the precoder codebooks, Type I CSI and Type II CSI.
• Type I CSI primarily targets scenarios where a single user is scheduled within
a given time/frequency resource (no MU-MIMO), potentially with
transmission of a relatively large number of layers in parallel (high-order
spatial multiplexing);
• Type II CSI primarily targets MU-MIMO scenarios with multiple devices
being scheduled simultaneously within the same time/frequency resource but
with only a limited number of spatial layers (maximum of two layers) per
scheduled device
