5G Physical Layer Training and Certification
This course of 5G physical layer covers all topics which are required to understand the 5G physical layer. This course covers all topics of physical layer like frequency bands, frame structure, carrier numbering, and all specifications. This course will help you to understand the concept of the physical layer completely and its specifications.
A physical layer forms the backbone of any wireless technology. NR physical layer has a flexible and scalable design to support diverse use cases with extreme requirements, as well as a wide range of frequencies and deployment options. The key components of the NR physical layer are modulation schemes, waveform, frame structure, reference signals, multi-antenna transmission, and channel coding. NR frame structure supports TDD and FDD transmissions and operation in both licensed and unlicensed spectrum. It enables very low latency, fast HARQ acknowledgments, dynamic TDD, coexistence with LTE, and transmissions of variable length. NR has an ultra-lean design that minimizes always-on transmissions to enhance network energy efficiency and ensure forward compatibility. DMRS is used to estimate the radio channel for demodulation. It is UE-specific, can be beamformed, confined in a scheduled resource, and transmitted only when necessary.
