This tutorial provides an overview of the LTE radio access with focus on the physical layer. Starting with a brief background of LTE and its creation, and an overview of the basic principles and the overall architecture, it continues with an in-depth description of the physical layer processing. Different transmission and access procedures such as cell search and random access are also described. Although the tutorial focuses on the physical layer, parts of the MAC and RLC layers are also described.
The presentation is divided into seven parts:
- Overview (18 slides, 29 min)
- overview, protocol structure, architecture, basic principles
- Downlink (23 slides, 34 min)
- overall structure, reference signals, multi-antenna transmission
- Downlink, cont’d (17 slides, 25 min)
- downlink control signaling
- Uplink (24 slides, 26 min)
- overall structure, reference signals, uplink control signaling
- TDD (8 slides, 9 min)
- TDD, half-duplex FDD
- Transmission Procedures (32 slides, 45 min)
- uplink power control, ICIC, retransmission mechanisms (MAC and RLC), scheduling
- Access Procedures (20 slides, 23 min)
- cell search, system information, random access
