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},

The CTIA 5G Millimeter-Wave Test Plan is based on the test requirements of a\nsmall subset of the 3GPP UE RF test cases, i.e.,\n? Maximum Output Power (MOP)\no Peak EIRP\no TRP\no Spherical Coverage\n? Reference Sensitivity (REFSENS)\no Peak EIS\no Spherical Coverage\nThis set of test cases was identified to reliably test the radiated RF power and receiver\nperformance of 5G Millimeter-Wave capable wireless devices.\nCTIA differed from 3GPP in some aspects, e.g., it focused on just a single Quiet Zone (QZ) size of\n30cm (in diameter) due to the upcoming introduction of phantoms that cannot fit into a QZ of less\nthan 30cm. In comparison, 3GPP decided to select 20cm and 30cm QZ sizes. Additionally, CTIA\ndefined just a single TRP quadrature and PDF scaling approach for constant-step size grids\nbased on the Clenshaw-Curtis weights. 3GPP decided to select both the Clenshaw-Curtis and\nsin(theta) based weights. Most importantly, CTIA augmented the amplitude quality of Quiet Zone\nvalidation with a phase validation to evaluate the phase variation inside the quiet zone.\nSpecifically, two phase quality of Quiet Zone procedures were introduced, i.e., the rotary scan and\nthe field probing approach. In 3GPP, only the amplitude quality of Quiet Zone approach was\nadopted.\nThe Near Field Phantom sub-working group is progressing in the definition of suitable Millimeter-\nWave phantoms, i.e., head phantoms, one-handed and two-handed grip hand phantoms. The\ninclusion of phantoms is intended in the next major revision of the CTIA Millimeter-Wave test plan.\nCTIA will continue to work with 3GPP and to provide input in the areas of evaluation\/maintenance\nof lab quality, establishment of measurement uncertainty criteria, and background in near-field\nphantom development to improve device certification going forward.\nIn order to guarantee alignment with 3GPP RAN4 and RAN5, continued regular communication\nbetween 3GPP and CTIA is planned.\nActions:\nNone","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":13170,"status":"noted","reservation_date":"2020-04-16 13:31:47","uploaded":"2020-04-16 13:45:19","revisionof":"","revisedto":"","release":"","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"5GmmW20404 OTA Radiated Performance Testing for 5G mmW User Equipment","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/TSG_RAN\/WG5_Test_ex-T1\/TSGR5_87_Electronic\/Docs\/R5-201317.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},
