To ensure alignment on interpretation of TS 38.101-1 between RAN4 and RAN5, RAN4 would like to inform RAN5 that for V2X applications, the transmitter and receiver characteristics are specified at the UE antenna connector, as illustrated in Figure 1, excluding any external components.\nActions: To RAN WG5: RAN4 respectfully asks RAN5 to take the above clarification into consideration when designing V2X Tx and Rx  conformance test and test procedure.","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":50340,"status":"noted","reservation_date":"2020-10-08 12:47:55","uploaded":"2020-10-08 13:30:03","revisionof":"","revisedto":"","release":"Rel-16","crspec":"","crspecversion":"","workitem":[{"winame":"5G_V2X_NRSL-Core"}],"crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"R4-2011710","lsreply":"","link":"https:\/\/www.3gpp.org\/ftp\/TSG_RAN\/WG5_Test_ex-T1\/TSGR5_89_Electronic\/Docs\/R5-205034.zip","group":"R5","meeting":"R5-89-e","year":2020,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0},

{"name":"R5-205038","title":"LS on Test Methodology for UE URLLC Ultra Low BLER Tests","source":"TSG WG RAN4","contact":"Ingbert Sigovich","contact-id":28887,"tdoctype":"LS in","for":"Information","abstract":"Under the release 16 work item on Physical layer enhancements for NR URLLC (NR_L1enh_URLLC), RAN4 discussed the feasibility of testing 1e-5 BLER test cases. RAN4 agreed to define 1e-5 BLER requirements. When developing the requirements, it was agreed that testing shall be performed with a 99.999% confidence level. RAN4 concluded that using the early pass\/fail test methodology unacceptably long test times could be avoided. Furthermore, RAN4 agreed that for the test requirement, in addition to the test tolerance a further 0.5dB should be added to the test requirement. The additional 0.5dB ensures that for a compliant device population, early pass will occur within a reasonable test duration. Based on these assumptions, RAN4 concluded that test times for fixed MCS test with 1e-5 BLER requirements are feasible. RAN4 suggests to add a supplementary X = 0.5dB to the RAN4 1e-5 BLER test requirements (in addition to TT) and capture this parameter X in RAN5 specification. Furthermore, RAN4 suggests RAN5 to use an adjusted early termination test method that ensures 99.999% CL. For information, the per step decision risk that was calculated as achieving this CL by different companies is provided in the Annex for reference purposes.\nTo RAN WG5 group.
