3GPP 38.300 v19.3.0 — the document's own text
4.9.4 OAM aspects
Taught in 4. What NR actually is, in the shape its own document gives it (TSG RAN — the group that specifies the radio, overview).
The transport connection between the NCR-node and its OAM may be provided by the NCR-MT's PDU session. A Network-Controlled Repeater may be configured with a list of allowed gNB cell(s) that the NCR-MT is allowed to connect with, and/or a list of forbidden gNB cell(s) that the NCR-MT is not allowed to connect with.
The information on the physical beam(s) used by NCR-Fwd for access link may be provided by OAM to the gNB and the Network-Controlled Repeater for operation. How to characterize and provide the physical beams of NCR-Fwd is up to implementation.
