[{"name":"R5-192995","title":"Discussion on TT of UL-MIMO test cases","source":"Huawei, Hisilicon","contact":"Chunying Gu","contact-id":65493,"tdoctype":"discussion","for":"Endorsement","abstract":"Associated CRs R5-192996, R5-192997, R5-192999\nAt RAN5#79 TT WF was agreed in R5-183952\n\u2013\tThe SA FR1 TT values should not exceed the value adopted in pure LTE (TS 36.521-1 BW = 20 MHz f = 4.2 GHz). It is assumed that the amount of uncertainty exceeding the E-UTRAN shall not be considered.\nAt RAN5#4-NR-Adhoc meeting, the MU&TT were discussed and the agreed values were captured in R5-190956. However, for several test cases with the requirements defined as the sum or the average power of each antenna, the TT are still FFS. This paper provides some consideration on those test cases.\nObservation 1: For LTE UL-MIMO test cases, the TT values are less than theoretical MU values.\nObservation 2: For NR UL-MIMO test cases, if FR1 TT WF is adopted, a UE may pass the single antenna test cases with any of its antennas, but fail the UL-MIMO test cases because of the more stringent TT.\nProposal 1: It is proposed to change the FR1 TT WF as below:\n\u2013\tThe SA FR1 TT values should not exceed the value adopted in pure LTE (TS 36.521-1 BW = 20 MHz f = 4.2 GHz) unless otherwise stated. It is assumed that the amount of uncertainty exceeding the E-UTRAN shall not be considered.\n\u2013\tFor UL-MIMO test cases with the requirements defined as the sum or the average power of each antenna, the SA FR1 TT values should not exceed theoretical MU (RSS of 2 non-UL-MIMO MUs) in pure LTE (TS 36.521-1 BW = 20 MHz f = 4.2 GHz).\nProposal 2: It is proposed to capture the TT values in the table into the specification.","secretary_remarks":"","agenda_item_sort_order":40,"ainumber":"4.1.16","ainame":"\tDiscussion Papers \/ Work Plan \/ TC lists","tdoc_agenda_sort_order":29950,"status":"noted","reservation_date":"2019-04-01 09:45:44","uploaded":"2019-04-02 09:21:20","revisionof":"","revisedto":"","release":"Rel-15","crspec":"38.521-1","crspecversion":"","workitem":[{"winame":"5GS_NR_LTE-UEConTest"}],"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\/R5-192995.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}]
