It includes support for mobile broadband data, mission-critical communication, and. Explore the concept of control resource sets (CORESETs) and how it applies to downlink control information. Learn the basics behind 5G NR waveforms, frame structure, and numerology. A 10-ms frame is divided into two half-frames, with each half-frame containing five subframes. 5G NR: Optimizing Ran design architecture to support new standards 14 5G NR Frame Structure –Frequency Domain PRB 0 PRB N1 PRB 0 PRB N2 PRB 0 PRB N3 PRB 0 PRB N4 1 2* SCS u 2 2* SCS u 4 2* SCS u 3 2* SCS u CRB 0 Base Reference Resource Block bandwidth 1. 143. The first is the overall architecture of the 5G network, showing you the tremendous change from the end-to-end of 5G technology. EXP-19 Years . It is based on orthogonal frequency-division multiplexing (OFDM), as is the 4G (fourth generation) long-term.
