LTE Air Interface
This training course will cover the major aspects of the LTE Air Interface in a manner that both technical and non-technical people will be able to fully appreciate. The course begins with a review of the LTE system architecture in order to fully establish the context of the radio interface operation and protocols. This initial section will also cover issues related to spectrum and deployment of LTE systems as well as comparing the 3 three main “evolutionary” radio technologies, LTE, WiMAX and UMB.
The central theme to LTE is the OFDMA and SC-FDMA radio multiplexing and modulation technique, the operation of this technology is explained and the choice of technologies used for LTE physical layer are justified. Layer 2 of the LTE protocol stack contains three sub-layers, MAC, RLC and PDCP as well as the control protocol RRC, and the main elements of each of these protocols is explained, showing how each relates to issues of mobility and mobility management with example of typical procedures given. Architectural and operational aspects of the Multicast Broadcast Multimedia Service are also covered.
