[LTE_309] Mastering TD-LTE Air Interface

Printer-friendly PDF version

Time Division Duplex Long Term Evolution (TDD LTE or TD-LTE) is a 4th generation (4G) cellular technology that promises a much higher air interface data rate (over 100 Mbps) to users while reducing the cost per bit for wireless service providers. The building blocks of TD-LTE include OFDM, multiple antenna techniques, and all-IP technologies. Multiple antenna techniques could increase data rates, throughput, coverage, and lower battery consumption in a mobile device. This course provides an in-depth discussion of the PHY and MAC layers of the TD-LTE air interface. First, it introduces the E-UTRAN network architecture and protocols. The Type 2 PHY frame structure, channels, resource allocation, and multiple antenna techniques are described. Finally, the course discusses the operations of acquisition, system access, data session setup, DL and UL traffic operations and handover.

Learning Objectives

After completing this course, the student will be able to:
• Sketch the network architecture
• Specify air interface protocols
• Draw PHY Type 2 frame structure and resource mapping for DL and UL
• Mention roles of DL and UL PHY channels
• Describe the synchronization operation and use of reference signals
• Summarize the system acquisition and data session setup procedure
• Describe traffic operations in DL and UL at the PHY/MAC layers
• Explain cell reselection and handover
• Identify the key multiple antenna techniques for the DL and the UL and specify their applications

Intended Audience
