[{"name":"R5-192901","title":"Response LS on multi-band relaxation","source":"TSG WG RAN4","contact":"Ingbert Sigovich","contact-id":28887,"tdoctype":"LS in","for":"Information","abstract":"Response to:\tR4-1900019 (original LS in R5-190729)\nRelease:\tRel-15\nWork Item:\tNR_newRAT-Core\nRAN4 thanks RAN5 for the LS on multi-band relaxation in R5-190729.  RAN4 has discussed the list of questions contained in the LS and has prepared the following responses:\n?\t?MBP\/S is defined based on measured value. If sum of ?MBP\/S is lower than SMBP\/S, UEs are regarded as 3GPP compliant (PASS). Only one verdict (PASS\/FAIL) will be concluded for UEs.\nIt is the RAN4 understanding that a PASS\/FAIL verdict per UE may reduce the readability of the conformance test result and that a verdict per UE per band is more useful.\nAccording to Clause 6.2.1.3 of TS38.101-2, ?MBP,n and ?MBS,n are band-specific relaxation parameters which are applied to the core requirements listed in Tables 6.2.1.3-1 and 6.2.1.3-3, respectively. It is the RAN4 understanding that these relaxations are UE implementation specific, provided that their sum across all of the FR2 bands supported by the UE is less than or equal to ?MBP and ?MBS, as defined in Table 6.2.1.3-4. One possible approach may be to allow UE manufacturers to declare which FR2 bands, and specific single row of Table 6.2.1.3-4, the device supports and the set of ?MBP,n and ?MBS,n so that the conformance testing procedure can calculate the PASS\/FAIL limit by applying the declared relaxation parameter to the single-band limits and thereby determine a PASS\/FAIL outcome per band.  It is assumed that the list of supported FR2 bands declared by the UE matches the related capability signaling.\n?\tIf sum of ?MBP\/S exceeds SMBP\/S, UEs are regarded as FAIL among all supporting FR2 bands.\nIn the RAN4 understanding, the sum of ?MBP,n and ?MBS,n over the FR2 bands supported by the UE is not allowed to exceed ?MBP and ?MBS by definition, as captured in Table 6.2.1.3-4. According to the possible manufacturer declaration approach, one or more measured results may fail the declared limit in one or more bands. In such an event, a certification test result capturing the PASS\/FAIL result per band can be helpful.\n?\tOnly exceeded values (> 0) are considered for MB calculation. (?MBP\/S = 0)\nIn the RAN4 understanding, ?MBP,n and ?MBS,n can be equal to 0, signifying that the manufacturer does not require any relaxation in the particular band.  RAN4 can further confirm that a negative relaxation (i.e. tightening of the single-band requirement) was not in the scope of the multi-band band framework agreement.\n?\tRegarding Note 3 (Upper limit in Band n260), if ?MBS exceeds 0.4 dB UEs are regarded as FAIL among all supporting bands.\nIn the RAN4 understanding, the relaxation factor ?MBS,n for Band n260 has an upper bound of 0.4 dB.\n?\tMulti-band test verdict is the sum of results for each band across different test points. (e.g. Frequency ranges, CHBW, SCS etc.)\nRAN4 is not aware of multi-band test verdicts being used for any OTA conformance testing in the past, such as E-UTRA, UTRA, or GSM.  In all of these cases, the core requirements have been defined per band, and conformance test verdicts have been recorded per band.  Different test points are considered per band and not across bands, and RAN4 has assumed the worst-case performance within a band as a minimum requirement.  In the case of NR FR2, the multi-band framework concept has introduced some flexibility for the UE manufacturer to optimize the UE radiated performance according to market needs. An approach based on UE declaration of the supported bands together multi-band relaxation factors can be used to calculate band-specific conformance test limits and to derive test verdicts per UE per band.\nRAN4 asks RAN5 to take the above information into account in their future work related to NR conformance test specification development.","secretary_remarks":"","agenda_item_sort_order":1,"ainumber":"2","ainame":"\tIncoming Liaison Statements","tdoc_agenda_sort_order":29010,"status":"noted","reservation_date":"2019-03-19 08:14:22","uploaded":"2019-03-19 08:16:24","revisionof":"","revisedto":"","release":"Rel-15","crspec":"","crspecversion":"","workitem":[{"winame":"NR_newRAT-Core"}],"crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"R4-1900019 \/ R5-190729","lsto":"","Cc":"","lsoriginalls":"R4-1902181","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/TSG_RAN\/WG5_Test_ex-T1\/TSGR5_AHs\/2019-04-08_5G-NR_Adhoc_5\/Docs\/R5-192901.zip","group":"R5","meeting":"R5-ah-35450","year":2019,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0},

As a secondary effect, the BS RF and UE RF specifications also have structures that depend on the different FR. For the UE the main difference between FR1 and FR2 is for conducted vs. radiated requirements, but there are also differences in requirement limits. For the BS, both conducted, radiated and \u201chybrid\u201d requirements are defined for FR1 for different BS types, while there is only radiated testing for FR2. The concepts, levels and scope of requirements also have differences.\nOn ACTION 1:\nIt is the view of RAN WG4 that it is feasible to extend FR1 from 6 GHz to 7.125 GHz in Rel-15 and it is also the preferable solution to accommodate inclusion of the new unlicensed operating bands in this frequency range. This should be done within the structures and scope of the present BS RF and UE RF specifications, including any possible impact on requirements and limits.\nThe extension of FR1 is implemented through CRs for Technical Specifications 38.101-1, 38.101-2, 38.101 3, 38.104, 38.141-1, 38.141-2, 38.113 and 38.124. In addition to the extension from 6 GHz to 7.125 GHz at the upper end, the FR1 range is at the lower end extended down to 410 MHz to accommodate future NR re-farming of the new LTE band at 410 \u2013 430 MHz.\nON ACTION 2:\nRAN WG4 concurs that the proposed extension of FR1 should not have any bearing on the selection of subcarrier spacing (SCS) in Rel-16 discussions for NR-U operation in the 6 GHz band. \nThe RAN WG4 agreed way-forward for the extension of FR1 is documented in the attached document R4 1902221.","secretary_remarks":"","agenda_item_sort_order":1,"ainumber":"2","ainame":"\tIncoming Liaison Statements","tdoc_agenda_sort_order":29020,"status":"noted","reservation_date":"2019-03-19 08:14:23","uploaded":"2019-03-19 08:16:24","revisionof":"","revisedto":"","release":"Rel-15","crspec":"","crspecversion":"","workitem":[{"winame":"NR_newRAT"}],"crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"R4-1900026","lsto":"","Cc":"","lsoriginalls":"R4-1902222","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/TSG_RAN\/WG5_Test_ex-T1\/TSGR5_AHs\/2019-04-08_5G-NR_Adhoc_5\/Docs\/R5-192902.zip","group":"R5","meeting":"R5-ah-35450","year":2019,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0},

Whether DL RMC for SDR requirements shall be introduced in RAN5 specifications is up to RAN5.\nRAN4 discussed whether to define a minimum duration of the SDR test (i.e. the minimum amount of subframes over which the TB success data rate shall be sustained) and observed that the respective parameter is related to the test uncertainty and is related to RAN5 scope. Therefore, RAN4 recommends RAN5 to define the SDR test duration and inform RAN4 if any additional inputs are needed.","secretary_remarks":"","agenda_item_sort_order":1,"ainumber":"2","ainame":"\tIncoming Liaison Statements","tdoc_agenda_sort_order":29030,"status":"noted","reservation_date":"2019-03-19 08:14:23","uploaded":"2019-03-19 08:16:24","revisionof":"","revisedto":"","release":"Rel-15","crspec":"","crspecversion":"","workitem":[{"winame":"NR_newRAT"}],"crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"R4-1902428","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/TSG_RAN\/WG5_Test_ex-T1\/TSGR5_AHs\/2019-04-08_5G-NR_Adhoc_5\/Docs\/R5-192903.zip","group":"R5","meeting":"R5-ah-35450","year":2019,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0},
