Course Overview
Long Term Evolution (LTE) is the new 3GPP standard for wireless broad band data services.  It comprises E-UTRA network, which uses OFDMA technology and EPC (Evolved Packet Core), an all-IP core network.  This framework allows the migration of 3GPP system towards packet-optimized system that supports multiple RATs (Radio Access Technologies), higher-data-rates and lower-latencies. Also it provides an evolutionary path for 3GPP and non-3GPP legacy technologies.
This course provides an in-depth discussion of LTE air interface.  It begins with an overview of LTE/E-UTRAN network architecture and protocols and introduces OFDMA, the key technology of LTE, and then discusses the DL and UL channels, signals and operations.  This is followed by a comprehensive discussion of MAC, RLC and PHY layers of the LTE air interface.
