We would like to inform RAN5 that GTI started developing a 5G Device Function and Performance Test Specification in June-2018. It is part of the overall 5G Device Certification programme in sub-6G bands for NSA and SA. It consists of a number of test chapters desgined to meet the specific test requirements by GTI operator members. They aim to complement the conformance tests desgined by RAN5 and certified by GCF. Chapter 10 of this test specification covers Data Throughput with a number of test cases included as listed in the appendix \nPlease note that 10.7 \u201dThroughput with CA\u201d list of test cases are not yet defined. The detail definition of the test cases can be found in latest version of the GTI 5G Device Function and Performance Test Specification v2.0 June-2019. A copy is attached. Below is the latest progress status of this test specification.\nGTI is very interested to see RAN5\u2019s plan to cover the 5G NR Application Layer Data Throughput Performance. This indeed is a very important test area to ensure the quality of service is delivered under very challenging data throughtput demand in a 5G network. GTI would be very happy to support RAN5 in this work and provide further input in due course. In the meantime, GTI would welcome comments and feedback on the above Data Throughput tests. \nGTI look forward to seeing the progress of this important study item and would kindly ask RAN5 to keep us informed.","secretary_remarks":"","agenda_item_sort_order":5,"ainumber":"3","ainame":"\tIncoming Liaison Statements","tdoc_agenda_sort_order":55170,"status":"noted","reservation_date":"2019-07-17 08:24:15","uploaded":"2019-07-24 17:48:03","revisionof":"","revisedto":"","release":"","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"R5-195422","lsto":"","Cc":"","lsoriginalls":"2019-TERM-03-LS-Reply to RAN5 LS \u201dStudy on 5G NR Application Layer Data Throughput Performance\u201d","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/TSG_RAN\/WG5_Test_ex-T1\/TSGR5_84_Ljubljana\/Docs\/R5-195517.zip","group":"R5","meeting":"R5-84","year":2019,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0},

To confirm its findings, ITU-R would like to share its views and ask for support regarding the following aspects:\n1)\tFor in-band signals, it would be possible to calculate TRP from measured e.i.r.p. with a priori knowledge of the directivity of the antenna. As previously stated by 3GPP RAN 4 (Document 5D\/1038), for wanted signal, if the directivity is known, it is enough to measure the peak e.i.r.p. and adjust it with the directivity to obtain TRP. \n\tOne approach indicated by Document 5D\/1207 coming from ITU-R Working Party 1C could be through availability of a \u201cbase station test mode\u201d, which can be applied in the field to control the operation of an AAS (Active Antenna Systems), to make the system under test only transmit a single beam with the highest possible gain in a given direction. \nITU-R is seeking more information and technical input about any currently implemented or planned feature in the 3GPP specifications to set the base station and its AAS as described above. \n2)\tTo use this method for emissions in the OOB and the spurious domains.\nITU-R would like to understand:\na)\tFor a base station active antenna system, what characteristic related to antenna frequency response and bandwidth can be assumed in the respective frequency domains which might be available as part of the 3GPP specifications?\nb)\tHow does the active antenna system radiation pattern change, including the direction of the main beam in the OOB domain with respect to change in frequency while being in \u201ctest-mode\u201d?\nWP 5D looks forward for a review from 3GPP RAN4 on these topics and in particular to receive responses to the aspects raised above and to continue the collaboration with 3GPP on this topic. \nIn order to progress the work within ITU-R, WP 5D would appreciate receiving more information, preferably before the ITU-R WP 5D meeting #34 which will be held on 19-26 February 2020 with a deadline for input contributions not later than 12 February 2020 at 1600 hours UTC.","secretary_remarks":"","agenda_item_sort_order":5,"ainumber":"3","ainame":"\tIncoming Liaison Statements","tdoc_agenda_sort_order":55260,"status":"noted","reservation_date":"2019-07-17 08:24:15","uploaded":"2019-07-24 17:48:03","revisionof":"","revisedto":"","release":"","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"5D_TD_810Rev1e_3GPP_RAN","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/TSG_RAN\/WG5_Test_ex-T1\/TSGR5_84_Ljubljana\/Docs\/R5-195526.zip","group":"R5","meeting":"R5-84","year":2019,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0}]
