3GPP TSG-RAN WG2 #130	R2-2504657
St. Julian’s, Malta, May 19th – 23rd, 2025

Agenda Item:	7.0.2.18
Source:	Ericsson
Title:	In-band operation for NB-IoT
Document for:	Discussion, Decision
1	

Conclusion
In the previous sections we made the following observations: 
Observation 1	RAN2 has already confirmed the technical feasibility of RAN4 assumptions.
Observation 2	RAN4's assumption that RRC should indicate guardband-r13 in operationModeInfo IE in MIB-NB does not have stage 3 impact in RAN2 specifications.

Based on the discussion in the previous sections we propose the following:
Proposal 1	Clarify in Stage 2 that only the same operation mode for anchor and non-anchor carrier is supported in NTN.
Proposal 2	Following option a), introduce a note in Table 5.5a-1 to clarify operation mode in NB-IoT NTN.
Proposal 3	There are no stage 3 issues related to the introduction of in-band support for NB-IoT.
