Such tests have provided a useful way to test close to real world performance of UEs. The interest in such tests has grown tremendously through 3G and 4G technologies. With 5G NR, there is an even greater increase in data transmission capacity as well as increase in demand for data by users of state-of-the-art high-data rate devices and applications. This has created a critical need to look into definition of conformance tests that measure 5G NR application layer data throughput performance.  \nDuring RAN5#83, RAN5 has initiated a Study Item to start definition of 5G NR Application Layer Data throughput tests (R5-194852). In order to enable these 5G NR Application throughput test procedures, two aspects are involved.  \na)\tRAN5 shall use existing (fixed reference measurement channel) demodulation performance scenarios already defined in TS 38.101-4 to develop application layer throughput test procedures for the same.\nb)\tThere is significant industry interest in also performing application layer throughput measurements with variable reference measurement channels (link adaptation), since this represents a scenario closer to real world deployments. \nObservations: \n-\tCore requirements are currently not defined in TS 38.101-4 for PDSCH throughput measurements in link adaptation\/variable reference measurement channel scenario. \n-\tRAN5 has identified an initial set of test parameters and scenarios in Tables A-1 through A-5 in the Annex of this LS, aligned with deployed scenarios and existing parameters in core specifications. RAN5 respectfully requests RAN4 to analyse these and\/or other parameters as deemed appropriate, for use in link adaptation scenarios and consider providing absolute physical layer throughput requirements. This shall enable RAN5 to develop application layer throughput tests for such scenarios.\n2. Actions: RAN5 requests RAN4:\n1) To accept to be added as secondory responsibility WG in the proposed Study item for 5G NR Application Layer Data Throughput Performance (please refer attachment R5-194852)\n2) That in order to proceed with the attached study item, to analyse the initial set of parameters identified in the appendix of this LS for use in link adaptation scenarios.\n3) To consider the possibility of defining physical layer throughput (link adaptation) requirements in 38.101-4 for the initial set of parameters identified in the appendix of this LS and\/or any other parameters, as deemed appropriate.","secretary_remarks":"","agenda_item_sort_order":272,"ainumber":"5.6","ainame":"\tOutgoing liaison statements for provisional approval","tdoc_agenda_sort_order":481100,"status":"revised","reservation_date":"2019-05-22 08:35:24","uploaded":"2019-05-22 08:37:54","revisionof":"","revisedto":"R5-195422","release":"Rel-15","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"TSG WG RAN4","Cc":"TSG RAN, GCF CAG, PTCRB PVG, CTIA, GTI","lsoriginalls":"","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/TSG_RAN\/WG5_Test_ex-T1\/TSGR5_83_Reno\/Docs\/R5-194962.zip","group":"R5","meeting":"R5-83","year":2019,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0},
