The LTE Radio Interface training course is aimed at telecommunications professionals involved with LTE, or those about to be involved with LTE. It covers those elements required for those working developed for telecom professionals working with hardware and software development, system engineering, testing and verification within LTE.
LTE Radio Interface Course Overview:
The LTE Radio Interface course contains all the relevant information required for telecommunications professionals wanting to learn about the LTE radio interface. It provides detailed information about the evolved radio access interface, E-UTRA that formed part of the updates for the Evolved Packet System, EPS that were in 3GPP Release 8.
The LTE Radio Interface course covers the OFDM-based radio interface physical layer in detail. The course describes the Layer 1 and gives the mapping of physical channels onto OFDM Resource Elements.
Downlink and uplink control channels for scheduling, Hybrid-ARQ operation and feedback signalling are all described in detail.
The course covers the layer 1 procedures for synchronisation, random access, scheduling, power control, sounding and Hybrid-ARQ. An overview of the basic concepts behind OFDM transmission and MIMO is also included.
