The industry association 3GPP defines any system using “5G NR” (5G New Radio) software as “5G”, a definition that came into general use by late 2018. The specific low-density parity-check (LDPC) codes and polar codes adopted by the 5G NR standard are described and performance and implementation advantages are compared with those of 4G LTE. From the series: 5G Tutorial. The frame structure for the type 2 frames used on LTE TDD is somewhat different. operator or Internet) LTE/EPC UE NR/EPC UE S1-MME S1-U SGi Gx Rx Sx LTE + NR RAN SGW/ PGW UP SGW/ PGW CP PCRF EPC NAS S11 HSS S6a MME S10 LTE RRC LTE PDCP LTE Uu S5 ›Enables early introduction of NR through connectivity. 5G is viewed as a flexible technology that is designed to meet the requirements of the diverse 5G use cases. 5G has more capacity than 4G, and 5G is designed to. A frame structure of NR is illustrated in Fig. This paper presents a comprehensive overview of the development of NR, including deployment scenarios, numerologies, frame structure, new waveform and enhanced carrier aggregation (CA).
