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 yAccess 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.
