Study Notes
Wireless Communication Networks: LTE, LTE-Advanced, and 5G
- The lecture covers wide area wireless access, including cellular networks from 1G to 5G.
- LTE-Advanced is an improvement over 3GPP Release 8, with key features like carrier aggregation and enhanced MIMO.
- Carrier aggregation combines up to 5 component carriers for a maximum bandwidth of 100 MHz.
- Enhanced MIMO supports up to 8 parallel layers or multi-user MIMO for up to 4 mobiles to receive signals simultaneously.
- Relaying uses relay nodes to extend the coverage area of an eNodeB, functioning as a new base station with smaller cell radius.
- Heterogeneous networks use small cells for low-powered access nodes and macro cells for typical cellular coverage.
- Coordinated Multipoint Transmission and Reception (CoMP) manages intercell interference and scheduling across distributed antennas and cells.
- Voice over LTE (VoLTE) uses IP Multimedia Subsystem (IMS) for voice over IP streams and Rich Communication Services (RCS) for additional services.
- 5G aims to cater to services with diverse requirements and uses key enabling technologies like software-defined networks (SDN) and network function virtualization (NFV).
- 5G overall architecture includes several deployment scenarios, such as enhanced mobile broadband (eMBB) and massive machine-type communications (mMTC).
- SDN separates control and data planes for network programmability, while NFV decouples network functions from hardware.
- The lecture includes review questions on topics such as cellular network organization, frequency reuse, handoff process, and comparison of generations.
