The Long term evolution (LTE) radio access network is a new physical technology to give user equipment (UE) access to the CORE network. The physical method used in LTE is based on OFDMA and SC-FDMA. For LTE-Advanced SC-FDMA will change to DFT-S-OFDM in UL. LTE allows to work on the air interface with flexible bandwidth (1.4 – 20 MHz). In LTE-A with carrier aggregation (CA) it is possible to have 5 times this frequency bands. The latency (<100 ms) in the access network is reduced and the data throughput is increased (up to 320 Mbps). In LTE-A we have up to 3/1,5 Gbps transmission with CA and more MIMO antennas. Protocol stacks are simplified and protocol states are reduced. 4 x MIMO antenna systems in downlink can be used. In LTE-A we use 8 x MIMO in downlink and 4 x MIMO in uplink. LTE-A is introducing Relay Nodes and CoMP transmission. It is evolving eSON, eHeNB, eMBMS. LTE-A will have the structure of heterogeneous networks and a new machine to machine communication is introduced. A new device to device communication is introduced especially for PWS. The CORE network is based on IP Multimedia Subsystem (IMS). LTE and LTE-A can work as a single network but is normally used together with GSM, UMTS and CDMA2000 networks. The training will also show the discussions beyond LTE-Advanced. LTE is defined from 3GPP in Release 8/9, LTE-A is defined in Rel 10/11/12/13/14 and 15.
The participants are familiar with telecommunication systems like GSM/UMTS. They will learn to understand the new LTE telecommunication network. From the physical level on the air interface up to the network design and the used protocols and messages.
This course addresses the needs of network operators, network planners, service providers, system developers and application programmers. The course focuses on both sides, UE/Mobile as well as network side.
