[{"name":"R5-216414","title":"LS on NB-IoT testing issues","source":"TSG WG RAN4","contact":"Ingbert Sigovich","contact-id":28887,"tdoctype":"LS in","for":"Information","abstract":"In August of 2020 RAN4 sent an LS to the FCC asking for guidance on NB-IoT testing issues near the edges of bands [1]. RAN4 received indirect feedback from the FCC on NB-IoT testing in [2]. RAN4 subsequently agreed CRs to solve the NB-IoT testing issue in Rel-14 [3], Rel-15 [4], Rel-16 [15] and Rel-17 [16]. The changes are summarized in the following table for NB-IoT operation in the USA, and especially that the lowest 100 kHz of Band 12 and Band 13 are not excluded for NB-IoT operation in the USA: \nTable 5.5F-1 E-UTRA operating bands for NB-IoT in the USA\nPlease note that 2199.0 MHz for B66 is an error. It should be 2179.9 MHz. This is being corrected. \nIn 36.101 the NB-IoT restriction for operation in the USA is tied to NS_04 signalling, but our understanding is that FCC certification does not use NS signalling. Therefore NB-IoT UEs shall not operate in the 100 kHz at the edge of the band when operating in the USA or\/and tested for FCC compliance even when NS_04 is not signalled.\n2. Summary\nTS 36.101 has been updated to exclude 100 kHz at the edge of NB-IoT bands for operation in the USA, except for the lower edge of Band 12 and Band 13 which are not excluded. \n3. Actions: To RAN5, PTCRB and CTIA CPWG: RAN4 asks RAN5, PTCRB and CPWG to take the above into consideration for NB-IoT testing.","secretary_remarks":"LS R5-206259 on failing initial registration without Retry-After header field from RAN5","agenda_item_sort_order":5,"ainumber":"3","ainame":"\tIncoming Liaison Statements","tdoc_agenda_sort_order":64140,"status":"noted","reservation_date":"2021-09-30 13:41:37","uploaded":"2021-10-12 19:22:31","revisionof":"","revisedto":"","release":"Rel-14","crspec":"","crspecversion":"","workitem":[{"winame":"TEI14"}],"crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"TSG WG RAN5","Cc":"PTCRB, CTIA CPWG","lsoriginalls":"R4-2114895","lsreply":"","link":"https:\/\/www.3gpp.org\/ftp\/TSG_RAN\/WG5_Test_ex-T1\/TSGR5_93_Electronic\/Docs\/R5-216414.zip","group":"R5","meeting":"R5-93-e","year":2021,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0},
