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}]
