Current 5G systems only supports maximum 16 layers .
Read moreWhat is NR physical layer?
NR physical layer design. A physical layer forms the backbone of any wireless technology . The NR physical layer has a flexible and scalable design to support diverse use cases with extreme (and sometimes contradictory) requirements, as well as a wide range of frequencies and deployment options.
