Course Description

Long Term Evolution (LTE) is a 4th generation wireless technology for wireless broadband services. LTE promises a much higher air interface data rate (over 100 Mbps in downlink speed and over 50 Mbps in uplink speed) to users. LTE network includes an E-UTRA network implementing OFDMA technology, and EPC (Evolved Packet Core) network implementing all-IP evolved core network. The building blocks of LTE air interface include OFDM, adaptive antenna systems, QoS, and advanced signaling techniques. These technologies can increase data rates, throughput, coverage and capacity, and lower battery consumption and latency in an LTE mobile device.


This course provides an in-depth discussion of LTE air interface including PHY, MAC, RLC, and PDCP layers. The course begins with an overview of LTE network architecture and then provides comprehensive coverage of OFDM, SC-FDMA, and TDD/FDD PHY frame structures, the key technologies of LTE. It then provides a detailed discussion of LTE channels, resource allocation, protocol layers, and adaptive antenna systems. This course describes how LTE advanced features such as LTE channels, resource allocation, adaptive antenna systems (AAS), QoS, adaptive modulation and coding (AMC), and advance signaling can significantly improve customer experience by increasing data rate and reducing latency and power consumption. Finally, the course discusses the operations of cell search and network acquisition, system access, data session setup, and handovers.
