LTE Air Interface
LTE Air Interface in Depth
Description
The LTE Air Interface Course will equip the participant with a complete understanding of the radio interface in Long Term Evolution (LTE) technology. General Overview is presented with the Key Advantages and Disadvantages.
This course will cover the 3GPP specifications work, with LTE Requirements and enablers. The Multiple Access techniques like OFDMA/ SCFDMA are discussed with their key parameters, Advantages & disadvantages. Then FDD/TDD Duplexing Scheme with reference to the frame structure will be shown.
Now the focus will be also on the physical channels structure, their processing in both FDD and TDD mode of LTE. The mapping of channels on the resource grid with the functionality of each channel is discussed in detail with respect to the call flow.
We will see the detailed analysis of the structure and features of the physical layer, layer 2 and layer 3 protocols, the radio link operation.
And then course also presents procedures of Radio Resource Management (RRM) power control, Admission Control, link adaptation, Uplink/Downlink Scheduler, and HARQ related to downlink and uplink scheduling. The concept of MIMO in LTE, idle mode behavior, and handover process are also discussed. The course is based on the 3GPP Technical Specifications and hence is equipment vendor-independent.
