As a secondary effect, the BS RF and UE RF specifications also have structures that depend on the different FR. For the UE the main difference between FR1 and FR2 is for conducted vs. radiated requirements, but there are also differences in requirement limits. For the BS, both conducted, radiated and \u201chybrid\u201d requirements are defined for FR1 for different BS types, while there is only radiated testing for FR2. The concepts, levels and scope of requirements also have differences.\nOn ACTION 1:\nIt is the view of RAN WG4 that it is feasible to extend FR1 from 6 GHz to 7.125 GHz in Rel-15 and it is also the preferable solution to accommodate inclusion of the new unlicensed operating bands in this frequency range. This should be done within the structures and scope of the present BS RF and UE RF specifications, including any possible impact on requirements and limits.\nThe extension of FR1 is implemented through CRs for Technical Specifications 38.101-1, 38.101-2, 38.101 3, 38.104, 38.141-1, 38.141-2, 38.113 and 38.124. In addition to the extension from 6 GHz to 7.125 GHz at the upper end, the FR1 range is at the lower end extended down to 410 MHz to accommodate future NR re-farming of the new LTE band at 410 \u2013 430 MHz.\nON ACTION 2:\nRAN WG4 concurs that the proposed extension of FR1 should not have any bearing on the selection of subcarrier spacing (SCS) in Rel-16 discussions for NR-U operation in the 6 GHz band. \nThe RAN WG4 agreed way-forward for the extension of FR1 is documented in the attached document R4 1902221.","secretary_remarks":"","agenda_item_sort_order":1,"ainumber":"2","ainame":"\tIncoming Liaison Statements","tdoc_agenda_sort_order":29020,"status":"noted","reservation_date":"2019-03-19 08:14:23","uploaded":"2019-03-19 08:16:24","revisionof":"","revisedto":"","release":"Rel-15","crspec":"","crspecversion":"","workitem":[{"winame":"NR_newRAT"}],"crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"R4-1900026","lsto":"","Cc":"","lsoriginalls":"R4-1902222","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/TSG_RAN\/WG5_Test_ex-T1\/TSGR5_AHs\/2019-04-08_5G-NR_Adhoc_5\/Docs\/R5-192902.zip","group":"R5","meeting":"R5-ah-35450","year":2019,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0}]
