The WID on UE Conformance \u2013 Enhanced support of reduced capability NR devices plus CT1 aspects in [1] has been introduced to RAN5, and the legacy signalling test cases adjustment for eRedCap UE has been discussed in [2] with the conclusion \u201cMeeting concluded analysis and findings are technically sound and thorough. Proposed way forward seems technically feasible. Commercial need for legacy test cases to be executed on eRedCap UE must be established first and if needed, timeline input from interested Operators must be sought before starting the work.

The RF test scope for eRedCap UE has been fully covered._x000D_\nb)\tRRM test coverage: No new RRM eRedCap specific TC was introduced in core WI, the RRM TCs for RedCap UE are also applicable to  eRedCap UE.
