Re-evaluation of alternative test methods are not precluded.\nRAN4 prefers that core requirements that ensure regulatory compliance be verified with no relaxation. RAN4 further advises that these regulatory-facing test cases have higher priority for resolution. \nRAN4 defers to RAN5 judgment, however, on relaxations needed during verification, to accommodate testability issues.\nSome contributions to estimate required relaxation (Relax_1) were treated.\nOff power, Rx Spurious, ACLR (absolute, relative), [SEM (FR2b)] are categorized as Low PSD.\nSEM (FR2a) is not categorized as Low PSD while SEM (FR2b) is TBD.\nDiscussions in MU session\nFrom perspective of operator, Option 4 (Don\u2019t test \/ To remove TC) can not be acceptable.\nOption 2 (Test without relaxation) is unrealistic for TCs which require much relaxation since MU becomes much larger.\nRelaxation can be acceptable even to regulatory items depended on value and TC.","secretary_remarks":"","agenda_item_sort_order":40,"ainumber":"4.1.16","ainame":"\tDiscussion Papers \/ Work Plan \/ TC lists","tdoc_agenda_sort_order":339800,"status":"noted","reservation_date":"2019-04-15 13:36:19","uploaded":"2019-04-15 13:37:57","revisionof":"","revisedto":"","release":"","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/TSG_RAN\/WG5_Test_ex-T1\/TSGR5_AHs\/2019-04-08_5G-NR_Adhoc_5\/Docs\/R5-193383.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}]
