Study Notes
5G NR Overview
- 5G NR (New Radio) is a 5G wireless communication standard
- Developed by 3GPP (3rd Generation Partnership Project)
- Provides faster data speeds, lower latency, and greater connectivity than 4G LTE
Key Features
- Millimeter Wave (mmWave): operates at high frequency bands (24 GHz, 28 GHz, 39 GHz) for faster data speeds
- Sub-6 GHz: operates at lower frequency bands (3.5 GHz, 4.5 GHz) for wider coverage
- Massive MIMO: uses large number of antennas to improve capacity and reduce interference
- Beamforming: focuses signal transmission and reception to improve spectral efficiency
Advanced 5G NR Technologies
- Ultra-Reliable Low Latency Communications (URLLC): enables mission-critical communications with latency < 1 ms
- Enhanced Mobile Broadband (eMBB): provides high-speed mobile broadband services
- Massive Machine-Type Communications (mMTC): supports low-power wide-area networks for IoT devices
5G NR Air Interface
- OFDM (Orthogonal Frequency Division Multiplexing): modulation scheme for downlink transmission
- SC-FDMA (Single-Carrier Frequency Division Multiple Access): modulation scheme for uplink transmission
- Polar coding: error correction technique for improved reliability
Network Slicing
- Network slicing: enables multiple independent networks to coexist on same physical infrastructure
- Slices: isolated, customizable networks for different services (e.g., IoT, eMBB, URLLC)
Security
- Authentication and Authorization: secure access to 5G networks and services
- Encryption: protects data transmission between devices and network
- Network Function Virtualization (NFV): virtualized network functions for improved security and flexibility
