During the discussion, it is noted that there are inconsistencies on the lower humidity limit in the normal temperature test environment among 2G\/3G\/4G\/5G specifications. The following examples list the excerption from some specifications for temperature conditions.\nTo track the issue on lower limit for humidity for normal test condition, we found that the issue had already been discussed in 3GPP meetings long time ago for GSM\/WCDMA\/LTE specs. At that time, there had already reached an agreement that no performance dependency on the lower limit for the humidity level is needed in 3GPP specs.\nThe reason for removing the lower humidity limit in normal conditions for 2G\/3G should be also applicable to LTE, NR systems, since it is expected E-UTRA, NR requirements will be tested in same or equivalent test rooms as GSM and WCDMA systems are used. It should also be made sure all systems can be used in same normal conditions.\nIn addition, ETSI ERM\/MSG TFES group agreed to remove the lower limit requirement from the EU harmonized standard EN 301 908-13, release 5, for E-UTRA UE requirements.\nSo for testing purpose, it doesn\u2019t make any sense to keep the lower limit for the humidity level. To avoid having to declare a lower limit value in UE test, the lower value has been removed in GERAN, UTRAN and E-UTRAN test spec [3-5].\nIn RAN5#94-e meeting online discussion, it is commented that RAN5 is tasked to align the temperature test environment with the core spec in RAN4. Considering the inconsistency among the specifications, RAN5 would like to know the exact reason why the test condition for humidity in E-UTRA\/NR specifications are different. RAN5 will further consider how to unify the normal test condition for humidity in E-UTRA\/NR test specifications based on RAN4 decision in core spec.\nActions: To RAN4 group: \tRAN WG5 requests RAN WG4 to provide the reason why the lower humidity limit in normal temperature test environment differs in GERAN\/UTRAN\/E-UTRAN\/NR. Are there any detail considerations to keep the lower humidity limit for normal test environment?","secretary_remarks":"","agenda_item_sort_order":583,"ainumber":"5.7","ainame":"Outgoing liaison statements for provisional approval","tdoc_agenda_sort_order":138800,"status":"approved","reservation_date":"2022-03-06 15:05:48","uploaded":"2022-03-08 07:51:06","revisionof":"","revisedto":"","release":"Rel-15","crspec":"","crspecversion":"","workitem":[{"winame":"5GS_NR_LTE-UEConTest"}],"crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"TSG WG RAN4","Cc":"","lsoriginalls":"","lsreply":"R4-2209631","link":"https:\/\/www.3gpp.org\/ftp\/TSG_RAN\/WG5_Test_ex-T1\/TSGR5_94_Electronic\/Docs\/R5-221604.zip","group":"R5","meeting":"R5-94-e","year":2022,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0},

In addition, RAN1 acknowledged via [5] that SCell drop due to priority rules can occur and that RAN1 has not identified any issue with the priority rules in TS 38.213.\nRAN5 is considering the usage of a conformance-only test function to test FR2 RF UL-CA conformance tests, for 3GPP Release 16 and forward. Such a conformance-only test function approach includes usage of a parameter that defines the power back-off needed to be applied to the PCell to potentially avoid SCell drop in FR2 UL-CA conformance test cases [3]. RAN5 will further define the test procedures to accomplish the FR2 UL-CA conformance test as per the attached draftCRs endorsed by RAN5 [7] [8] [9].\nRAN5 requests RAN4 for responses to the following questions:\na)\tWhether RAN4 sees a need to define within TS 38.101-2, the aforementioned power backoff parameter which will be used by conformance-only test function?\nb)\tWhether RAN4 can share guidance on any impact on absolute and relative power tolerance accuracy that needs to be factored because of usage of such a conformance-only test function to apply power limits\/back-off?\nActions: To RAN4 group: \tRAN5 requests RAN4 group to provide feedback on the questions raised above.","secretary_remarks":"","agenda_item_sort_order":583,"ainumber":"5.7","ainame":"Outgoing liaison statements for provisional approval","tdoc_agenda_sort_order":141500,"status":"approved","reservation_date":"2022-03-06 15:05:52","uploaded":"2022-03-08 07:51:06","revisionof":"","revisedto":"","release":"Rel-16","crspec":"","crspecversion":"","workitem":[{"winame":"5GS_NR_LTE-UEConTest"}],"crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"TSG WG RAN4","Cc":"","lsoriginalls":"","lsreply":"","link":"https:\/\/www.3gpp.org\/ftp\/TSG_RAN\/WG5_Test_ex-T1\/TSGR5_94_Electronic\/Docs\/R5-221617.zip","group":"R5","meeting":"R5-94-e","year":2022,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0}]
