[{"name":"R5-201318","title":"LS on requirement in Power Class 2 for UL MIMO Test cases","source":"GCF CAG","contact":"Ingbert Sigovich","contact-id":28887,"tdoctype":"LS in","for":"Action","abstract":"GCF CAG reviewed validation CRs related to 5G NR UL MIMO from 3GPP TS 38.521-1. Validations of SA UL-MIMO TCs for PC2 are on hold due to the below perceived uncertainties.\na)\t GCF CAG noticed that as per 3GPP 38.101-1 v15.9.0 clause 6.2.1, if for an NR band UE reports as Power Class 2 (PC2) it shall meet PC2 requirements. But as per 3GPP TS 38.101-3 v15.9.0 sub-clause 6.1 states:\n\"...if UE indicates IE maxNumberSRS-Ports-PerResource = n2 in NR standalone operation mode,  the said UE shall meet the NR requirements for either power class 2 or power class 3 in EN-DC within FR1 if UE indicates IE maxNumberSRS-Ports-PerResource = n1 for EN-DC on this NR band.\"\nHowever, GCF CAG also noticed that this statement has been removed in Rel-16 in TS 38.101-3 v16.3.0 sub-clause 6.1. \nb)\tAs Per section 6.2D.1 of 3GPP 38.101-1 v15.9.0:\n\" If UE is configured for transmission on single-antenna port, the requirements in clause 6.2.1 apply.\"\nc)\tAs per above the requirements for a UE configured in a particular way (see point a) the PC requirements are different in 38.101-1 v15.9.0 and 38.101-3 v.15.9.0. GCF CAG considers this requirement to be very important for test coverage.\nd)\tPC2 NSA requirement as referenced in TS38.101-3 subclause 6.1 is not fully concluded yet in RAN4.\nActions\nGCF CAG kindly asks 3GPP RAN4 to:\n1.\tTo provide road map when the ambiguities of PC2 (see a,b and d above) will be resolved to enable GCF to start validation of power class dependent test cases.\nGCF CAG kindly asks 3GPP RAN5:\n1. To confirm if test coverage for requirement in bullet point b above is adequately provided in the 3GPP RAN5 test cases.","secretary_remarks":"","agenda_item_sort_order":39,"ainumber":"5.2","ainame":"\tReview incoming LS (fm A.I. 3) & new subject discussion papers","tdoc_agenda_sort_order":13180,"status":"noted","reservation_date":"2020-04-16 13:31:47","uploaded":"2020-04-29 07:59:08","revisionof":"","revisedto":"","release":"","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"CAG-20-193r3","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/TSG_RAN\/WG5_Test_ex-T1\/TSGR5_87_Electronic\/Docs\/R5-201318.zip","group":"R5","meeting":"R5-ah-38102","year":2020,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0}]
