TA-TC 6800

   

Dauer:

3 days (web session 3x4 hours)

   

Zielgruppe:

Personnel from technical departments (especially planning and rollout)

   

Zielsetzung:

This course presents the technology of the 5G mobile network on the basis of 3GPP, especially that of the 5G radio access network. After a view on the evolution of mobile communication towards 5G the 5G network elements, interfaces and radio access protocols are discussed in detail as well as procedures related to connection setup, connection release and mobility. As stand alone 5G networks do not exist yet, inter-RAT dual connectivity towards LTE and 5G is shown as preliminary solution to give access to 5G. Next the channels to transmit signaling and user data within the 5G radio access network are described together with the most important physical procedures for initial access and data transmission. Finally the air interface is discussed with focus to features achieving higher data rates like bigger band width offered by high frequency carriers, beamforming and massive MIMO. A short description of the most import coverage and quality performance indicators is given as well.
