5G NR Physical Layer | Chapter 11| Layer Mapping

[@TurbidSugar19]

What difference between Layer Mapping and Precoding?
Because the main purpose of the precode matrix is to Map between Antena ports and layers.
Is it just split large TransportBlock into one that cant be transmitted, let's say for rank 4 - 4 smaller blocks that can be transmitted due to SPEC constraints?

[@jyothiyeruva329]

Here Multiple antenna means, are you addressing to multiple antenna ports?

[@curiousbeing8585]

Yes

if you able to cover analog, digital and hybrid beam forming will be really helpful
