ITU-T SERIES G SUPP 75 PDF

This Supplement studies the best application scenario of TDM-PON in 5G small cell backhaul and midhaul, and researches and determines related technical requirements.

NOTE – Annex A of [b-3GPP TR 38.801] on "Transport network and RAN internal functional split" considers functional split Options1-8. Because the split is an internal splitting within 5G RAN, it is not about the backhaul [b-3GPP TR 38.801] F1 interface (CU to DU split), which is defined as midhaul [b-3GPP TS 38.470]. Concurrent support for RAN deployment scenarios is outlined in [b-ITU-T GSTP-TN5G]. The definition of ITU-T is also used in O-RAN. In this Supplement, the focus is on midhaul and backhaul over the time-division-multiplexing passive optical network (TDM-PON). The fronthaul over TDM-PON is studied in other Supplements.
