[{"name":"R5-236039","title":"Reply LS on applicability of UE demodulation and CSI requirements for IoT-NTN UE","source":"TSG WG RAN4","contact":"Ingbert Sigovich","contact-id":28887,"tdoctype":"LS in","for":"Information","abstract":"RAN4 thanks RAN5 for raising these questions. After discussion, RAN4 would like to clarify applicability on demodulation and CSI requirements for Category M1 UE over NTN.\nBased to TS36.306 Clause 4.3.38.1, Category M1 UE supporting NTN access (ntn-Connectivily-EPC-r17) shall also support the Rel-13 Category M1 CE Mode A UE capability (ce-ModeA-r13). \n4.3.38.1\tntn-Connectivity-EPC-r17\nThis field indicates whether the UE supports NTN access. This field is only applicable if the UE supports ce-ModeA-r13 or any ue-Category-NB.\n[\u2026]\nTherefore, according to RAN2 specification above, there are no Category M1 NTN UEs only supporting NTN access. \nAnswer to Q1 and Q2: There are no Category M1 NTN UEs only supporting NTN access. Demodulation and CSI testing of TN Category M1 in TS36.101 will suffice even if testing in a different frequency band.\nAnswer to Q3: As for the Table B.2-1 in TS 36.102, it is only applicable for Category M1 UEs and not applicable for Category NB1\/NB2. RAN4 will add a new connection setup table for Category NB1\/NB2 UEs in TS36.102 Clause B.2.\nActions To RAN WG5: RAN4 requests RAN5 to?take the above information into account for their further work.","secretary_remarks":"","agenda_item_sort_order":19,"ainumber":"4.5.4","ainame":"\tOther open issues from joint sessions - original A.I. retained","tdoc_agenda_sort_order":60390,"status":"noted","reservation_date":"2023-10-24 05:05:56","uploaded":"2023-10-24 05:31:23","revisionof":"","revisedto":"","release":"Rel-18","crspec":"","crspecversion":"","workitem":[{"winame":"LTE_NBIOT_eMTC_NTN_req-UEConTest"}],"crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"","lsreply":"","link":"https:\/\/www.3gpp.org\/ftp\/tsg_ran\/WG5_Test_ex-T1\/TSGR5__101_Chicago\/Docs\/R5-236039.zip","group":"R5","meeting":"R5-101","year":2023,"uicc_affected":"","me_affected":"","ran_affected":"","cn_affected":"","clauses_affected":"","crsinpack":null,"crsinpacknumber":0}]
