[{"name":"R5-241876","title":"LS reply on FR2 ACS\/IBB testing","source":"TSG WG RAN5","contact":"Ingbert Sigovich","contact-id":28887,"tdoctype":"LS out","for":"Approval","abstract":"RAN5 would like to thank RAN4 for the LS [1]. RAN5 has discussed it over the attached discussion paper [2] and has made the following observations:\n\n\u2022\tACS\/IBB test cases do not require to test at EIS level but a specific total DL power for the wanted signal and the modulated interferer respectively.\n\u2022\tWhen a specific total DL power is required in a test, it is expected that power is equally split between both polarizations.\n\u2022\tWhen blocking measurement procedure in section K.1.8 in [4] was defined, it was decided not to test both polarizations at the same time and to add a clarification indicating that each polarization needs to transmit 3dB below the level stated in the requirement.\n\u2022\tTesting both polarizations simultaneously or sequentially should not imply changes in the power levels to test.\n\nRAN5 concludes that current 3dB power backoff per polarization applied in the blocking measurement procedure defined in section K.1.8 in [3] is correct. However, for wanted signal in particular, section K.1.8 in [3], step 5, talks about EIS level which is incorrect and misleading, and that has probably driven into the LS request in [1]. \n\nTo resolve the ambiguity, RAN5 has agreed to remove \u201cEIS\u201d term in attached CR [3] as follows:\n\n5)\tApply a signal with the specified reference measurement channel on the ?-polarization, setting the power level of the signal 3dB below the EIS level stated in the requirement.\n6)\tApply the blocking signal with the same polarization and coming from the same direction as the downlink signal. Set the power level of the blocking signal 3dB below the level stated in the requirement.\n\n\n2. Actions: To RAN4 group: RAN5 asks RAN4 to consider the observations and attachments shared in this LS explaining RAN5 view on why no changes are required in the blocking measurement procedure other than the clarification above.","secretary_remarks":"","agenda_item_sort_order":647,"ainumber":"5.7","ainame":"Outgoing liaison statements for provisional approval","tdoc_agenda_sort_order":157400,"status":"approved","reservation_date":"2024-07-03 14:53:11","uploaded":"2024-03-07 15:01:13","revisionof":"","revisedto":"","release":"Rel-15","crspec":"","crspecversion":"","workitem":[{"winame":"TEI15_Test"},{"winame":" 5GS_NR_LTE-UEConTest"}],"crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"TSG WG RAN4","Cc":"","lsoriginalls":"","lsreply":"","link":"https:\/\/www.3gpp.org\/ftp\/tsg_ran\/WG5_Test_ex-T1\/TSGR5__102_Athens\/Docs\/R5-241876.zip","group":"R5","meeting":"R5-102","year":2024,"uicc_affected":"","me_affected":"","ran_affected":"","cn_affected":"","clauses_affected":"","crsinpack":null,"crsinpacknumber":0},
