[{"name":"R5-202320","title":"On frequency flatness uncertainty for FR2 RRM and Performance tests","source":"Anritsu","contact":"Hiroyuki Baba","contact-id":65585,"tdoctype":"discussion","for":"Endorsement","abstract":"In [1], the table format for the uncertainty budget table for Performance test is endorsed. In this paper we propose the MU term \u201cDL AWGN and signal flatness\u201d factor for FR2 RRM and Performance test cases. \nDiscussion\nIn LTE and in FR1 NR up to 40MHz BW,+\/-  2.0 dB (1.96sigma) was applied for MU term \u201eDL AWGN and signal flatness\u201d. The same value is used for both RRM and performance test cases.\nGenerally saids, spectrum flatness will become bigger for wider BW. As in FR2, we need to consider wider BW than FR1, then the flantess value becomes bigger than those in LTE or FR1. With our internal evaluation of test system, DL signal flatness is within +\/- 3.0dB for both FR2a and FR2b and up to 400MHz BW. \nFor performance test, the test case needs full RBs allocation then we propose to apply +\/- 3dB for all the cases we see up to 400Mhz BW.\nProposal 1: For FR2 performance test, apply +\/-3.0 dB(1.96sigma) for MU term of AWGN and signal flatness for both FR2a and FR2b for up to 400MHz.\nFor RRM, only RLM test uses flaness factor as MU contributor and it is counted to total MU with the same way as demodulation test( i.e 0.25 * flatness) in LTE\/NR FR1. We need some more study whether the flantess factor with the full BW assumption can be applied for RLM test case as is as it can be considred that SS-PBCH block, which is narrower than total BW, may be more relevant for RLM performance.  We may need more understanding how flatness factor can impact the RLM test case.\nObservation 1 : Flatness impact for RRM test needs further study.","secretary_remarks":"","agenda_item_sort_order":89,"ainumber":"5.3.2.17","ainame":"\tDiscussion Papers \/ Work Plan \/ TC lists","tdoc_agenda_sort_order":23200,"status":"revised","reservation_date":"2020-05-08 12:41:59","uploaded":"2020-05-09 02:12:46","revisionof":"","revisedto":"R5-202851","release":"","crspec":"","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_87_Electronic\/Docs\/R5-202320.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}]
