Regarding the questions in the LS, please see below RAN4\u2019s responses. \nQ1: RAN5 is looking to develop test procedure with and without UE Beamlock test function, can either procedure be used to verify RAN4 core requirements?\nAnswer: \tThere is no consensus on the reply to Q1.\nQ2: Regarding the verification of spherical coverage requirement for initial access and RRC_INACTIVE using UE Beamlock test function in the IDLE mode, will it prevent UE to not autonomously choose Uplink beams? \nWill using beam lock prevent UE from autonomously choosing other beams even if UE\u2019s behaviour is such?\nAnswer: RAN4 is of the following view:\n\u2022\tUsing beamlock function in testing does not prevent UE from choosing UL beams in the real field.\n\u2022\tIn the beamlock function based test, UE should still be able to autonomously choose the UL beams based on DL measurement before the beamlock function is activated. \no\tRAN4\u2019s understanding is that beamlock function should be activated after the UL beam is autonomously chosen.\n\u2022\tOnce the beam is locked, UE cannot autonomously change the UL beams.  \n\u2022\tThe exact test setup should be decided by RAN5. \nQ3: Regarding the verification of spherical coverage requirement for initial access and RRC_INACTIVE without using UE Beamlock test function in the IDLE mode, would this be aligned to verifying RAN4 core requirements when the requirements were defined?\nAnswer: There is no consensus on the reply to Q3.\n\t\nActions: To RAN5: \tRAN4 respectfully asks RAN5 to consider the above responses in its work.","secretary_remarks":"LS R5-206259 on failing initial registration without Retry-After header field from RAN7","agenda_item_sort_order":24,"ainumber":"5.2","ainame":"Review incoming LS (fm A.I. 3) & new subject discussion papers","tdoc_agenda_sort_order":180,"status":"noted","reservation_date":"2026-07-01 18:12:18","uploaded":"2026-01-07 18:12:41","revisionof":"","revisedto":"","release":"Rel-18","crspec":"","crspecversion":"","workitem":[{"winame":"NR_RF_FR2_req_Ph3-UEConTest"}],"crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"","lsreply":"","link":"https:\/\/www.3gpp.org\/ftp\/tsg_ran\/WG5_Test_ex-T1\/TSGR5__110_Gothenburg\/Docs\/R5-260018.zip","group":"R5","meeting":"R5-110","year":2026,"uicc_affected":"","me_affected":"","ran_affected":"","cn_affected":"","clauses_affected":"","crsinpack":null,"crsinpacknumber":0}]
