Expand. PDF. 2 and 6. 5G) is a name for 3GPP release 18, which as of 2021. D. The topics covered are: Waveforms and frame structure. Introduction. It is based on orthogonal frequency-division multiplexing (OFDM), as is the 4G (fourth generation) long-term. 1 Mbps. A comprehensive overview of the state-of-the-art development of NR is offered, including deployment scenarios, numerologies, frame structure, new waveform, multiple access, initial/random access procedure, and enhanced carrier aggregation (CA) for resource requests and data transmissions. A four-element dual-frequency MIMO antenna system which can cover N78 (3. Fronthaul network. 2017.
