[{"name":"R5-201310","title":"LS to RAN5 on NR DL RMC configuration for UE ACS tests","source":"TSG WG RAN4","contact":"Ingbert Sigovich","contact-id":28887,"tdoctype":"LS in","for":"Information","abstract":"Release:\tRelease 15\nWork Item:\tNR_newRAT-Core\nRAN4 has identified that the NR UE receiver ACS test requirements for PDCCH\/DCI could be tighter than PDSCH due to that the PDCCH\/DCI may not occupy the entire channel bandwidth where the signal power is lower than that of PDSCH as defined in ACS core specifications. To mitigate this potential issue, RAN4 has agreed to modify the NR DL RMC configuration for UE ACS tests for both FR1 and FR2 by combining the following two solutions:\n1.\tMaximize the PDCCH Aggregation Level (AL) as long as it fits into the channel BW, such as for FR1 AL = 4 for 5MHz, AL = 8 for 10MHz and 15MHz, and AL = 16 for > 15MHz. The same approach also applies for FR2.\n2.\tCORESET size is defined by removing both edge PDCCH allocations from full bandwidth, such as shown below.[]\nNotice that in Solution 1, the definition of nrofcandidates for AL = 8 and AL = 16 in TS 38.508-1 needs to be revisited. Also in Solution 1, by changing the aggregation level, there is a possibility that the number of monitored PDCCH will reach the maximum number of monitored PDCCH candidates which is defined in TS 38.213 clause 10.2. In that case there is a need to adjust the number of monitored PDCCH candidates per slot.\nOn the other hand, since the DL reference measurement channel is common for all UE RF receiver requirements, the proposed modification for ACS tests may also apply to other UE RF receiver tests in order to maintain the consistency in DL RMC test configuration. However, RAN4 consents that it is up to RAN5\u2019s decision as whether the same modification should be applied to other UE RF receiver tests or not.\nActions:\nRAN4 asks RAN5 to take the above agreements in RAN4 into consideration when developing the NR UE receiver test specifications.","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":13100,"status":"noted","reservation_date":"2020-04-16 13:12:20","uploaded":"2020-06-10 14:56:14","revisionof":"","revisedto":"","release":"Rel-15","crspec":"","crspecversion":"","workitem":[{"winame":"NR_newRAT-Core"}],"crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"R4-2005205","lsto":"","Cc":"","lsoriginalls":"","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/TSG_RAN\/WG5_Test_ex-T1\/TSGR5_87_Electronic\/Docs\/R5-201310.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}]
