Who pushed what

Should LT5 (e)RedCap reuse legacy 1Rx requirements for RLM and BFD?

China Mobile and vivo each proposed reusing the legacy 1Rx TEvaluate_out_SSB,RedCap requirement. CATT observed that less than 5 MHz does not affect minimum or relaxed RedCap RLM and BFD requirements.

China MobileProposes reusing the legacy 1Rx TEvaluate_out_SSB,RedCap requirement for LT5.
Proposal 1: it is proposed to reuse the legacy 1Rx (e)RedCap TEvaluate_out_SSB,RedCap requirement for 1Rx (e)RedCap UE supporting LT5.

vivoAlso supports reusing the legacy 1Rx TEvaluate_out_SSB,RedCap requirement for LT5.
For RLM/BFD TEvaluate_out_SSB,RedCap of 1Rx (e)RedCap UE supporting LT5, support to reuse the legacy 1Rx (e)RedCap TEvaluate_out_SSB,RedCap requirement for 1Rx (e)RedCap UE supporting LT5.

Which existing requirements should be reused for HD-FDD VSAT in FR2-NTN, and where should they sit?

Huawei and HiSilicon proposed reusing FR1-NTN RRM requirements; Ericsson proposed applying existing FR1-numerology HD-FDD VSAT agreements to FR2 numerology. Samsung proposed analyzing reuse of legacy FR2-NTN UE requirements, while ZTE and Sanechips proposed placing phase 2 HD-FDD requirements under FR2-NTN RRM clauses.

Huawei (with HiSilicon)Huawei and HiSilicon propose reusing FR1-NTN RRM requirements.
Proposal: Re-use RRM requirements for HD-FDD VSAT in FR1-NTN to HD-FDD VSAT in FR2-NTN.

Coverage: RAN4 #120 (Maastricht, 2026-08-24 to 2026-08-28), agenda items 4.2.1.4, 7.14.4, 7.15.3, 7.4.3.2, 7.6.4.2, 7.6.6.2. Scout read 8 recorded decisions and 12 company positions or contribution passages on these agenda items (catalog synced 2026-09-29) and cites 8 decisions and 8 positions from 16 TDocs. Every quoted passage was matched verbatim against the TDoc text; the summaries around the quotes are Scout's reading. Register statuses are copied from the 3GPP TDoc register: not treated means a document was not handled on its own, though its content may have fed feature-lead summaries or merged revisions. Not covered: other agenda items and meetings, plenary TDocs and plenary decisions after the meeting, email discussions after the meeting, and anything not yet in the chair notes or register.

  • The pack has no evidence on the 6G UE group for RRM.
  • UE RF requirements are represented only by a single-company timing and frequency contribution, with no recorded decision in the pack.
  • No FFS item or working assumption is supplied for these topics.
