  ITU-T A.5 justification information for referenced document 3GPP TS 38.300 V18.6.0 (2025) in draft Y.3166
1. Clear description of the referenced document:
Name: 3GPP TS 38.300 V18.6.0 (2025)
Title: NR and NG-RAN Overall Description Stage 2 (Release 18)
2. Status of approval:
Approved
3. Justification for the specific reference:
Refer to the 3GPP specification TS 38.300 to describe the existing network capabilities and resources provisioning procedures, in particular the Fifth Generation (5G) New Radio (NR) high-level procedures, which are required not to be affected by the UE-to-UE session signalling procedures. The requirement for the support the mutual independence and coordination of the UE-to-UE session procedures and the network capability and resource provisioning procedures [3GPP TS 38.300] is also covered in Y.U2USM-req-fra.
4. Current information, if any, about IPR issues:
None.
5. Other useful information describing the "Quality" of the document:
3GPP TS 38.300 V18.6.0 is published by 3GPP in June 2025.
6. The degree of stability or maturity of the document:
3GPP TS 38.300 V18.6.0 is published by 3GPP in June 2025.
7. Relationship with other existing or emerging documents:
ITU-R M.2150-1 contains radio interface specifications, and evaluation criteria for multiple Radio Interface Technologies (RITs) and Set of RITs (SRITs), it has relationship with this specification.
