LTE Physical Layer - Apis Training

The course also includes a chapter on the evolution of the LTE physical layer standard (Release-10 to Release-13) for features such as carrier aggregation, enhanced MIMO and dual connectivity. Note: the course does not cover the TDD option for LTE.

Prerequisites

Basic knowledge regarding the architecture, terminology and modes of operation of the LTE radio access network is highly recommended. Knowledge about UMTS High Speed Packet Access concepts is useful but not mandatory.
