Interfaces to the transport network from 5G/IMT2020 networks are used to request transport services. Various parameters of those requests include capacity and latency to support between interface users. These are consolidated in the following tables. Capacity Table 7-1 Capacity requirements At F1 From [4], option 2 interface DL 4016 Mb/s; UL 3024 Mb/s At Fx From [4], option 7a, 7b interface DL: 10.1~22.2 Gb/s 37.8~86.1 Gb/s UL: 16.6~21.6 Gb/s 53.8~86.1 Gb/s At Xn 25Gb/s-50Gb/s interface At NG For CU: 10Gb/s-25Gb/s interface For CN: 100+Gb/s Fronthaul Dependent on number of CPRI and eCPRI interfaces. See also Table 1 in 5.3.1. 10Gb/s-825Gb/s Midhaul Varies with number of interfaces. and 25Gb/s-800Gb/s Backhaul Base These relate to a combination of NG and Xn interfaces, and reflects the station capacity based on a gNB for 3 cells with 64T 64R antennas for low frequency (gNB) and 2T 2R for high frequency. Peak: 6.14Gb/s for 5G LF (low frequency) 19.8Gb/s for 5G HF (high frequency) Average: 2.97Gb/s for 5G LF; 9.9Gb/s for 5G HF
