{"name":"R5-211609","title":"Clarification on exception requirements for Intermodulation due to Dual uplink (IMD)","source":"TSG WG RAN5","contact":"Ingbert Sigovich","contact-id":28887,"tdoctype":"LS out","for":"Approval","abstract":"When defining test points in EN-DC REFSENS test cases, RAN5 is making a per configuration analysis of the needed test points to sufficiently cover the core requirements in 38.101-1 and 38.101-3. \nSpecifically, for inter-band EN-DC configurations affected by 2UL IMD, RAN5 seek clarification from RAN4 regarding the applicability of requirements.\nIn general, it is clear that the REFSENS requirements in 38.101-3 clause 7.3B are exceptions to the standalone (SA) requirements in 36.101 and 38.101-1, meaning the SA requirements apply if the exception condition is not met. This is supported by the statement in 38.101-3 V16.6.0 clause 7.3B.1:\nFor the case of inter-band EN-DC with a single carrier per cell group and multi carrier per cell group, in addition to the E-UTRA and NR single carrier, CA, and MIMO operation of REFSENS requirements defined in TS 38.101-1 [2], TS 38.101-2 [3], and TS 36.101 [4], the REFSENS requirements specified therein also apply with both downlink carriers and both uplink carriers active unless sensitivity exceptions are allowed in this clause of this specification, clause 7.3 in TS 38.101-1 [2] or clause 7.3 in TS 36.101 [4]. \nThe requirements for UL Harmonic interference exceptions in clause 7.3B.2.3.1 (Reference sensitivity exceptions due to UL harmonic interference for EN-DC in NR FR1) are defined in a way such that it is clear when the exception apply and when it is not:\nNOTE 4:\tThese requirements apply when there is at least one individual RE within the uplink transmission bandwidth of the aggressor (lower) band for which the 5th transmitter harmonic is within the downlink transmission bandwidth of a victim (higher) band.\nHowever, RAN5 has noticed that the requirements for 2UL IMD in clause 7.3B.2.3.5 (MSD for intermodulation interference due to dual uplink operation for EN-DC in NR FR1) are written in a way that can be interpreted as not following the same approach. \nFor EN-DC configurations in NR FR1 with uplink and downlink assigned to E-UTRA and NR FR1 bands given in Table 7.3B.2.3.5.1-1, Table 7.3B.2.3.5.1-1a, Table 7.3B.2.3.5.2-0 and Table 7.3B.2.3.5.2-1 the reference sensitivity is defined only for the specific uplink and downlink test points specified in Table 7.3B.2.3.5.1-1, Table 7.3B.2.3.5.1-1a, Table 7.3B.2.3.5.2-0 and Table 7.3B.2.3.5.2-1. For these test points the reference sensitivity levels specified in clause 7.3.1 in TS 36.101 [4] and 7.3.2 of TS 38.101-1 [2] for the corresponding channel bandwidths or in clause 7.3.1 of TS 36.101 [4] are relaxed by the amount of the parameter MSD given in Table 7.3B.2.3.5.1-1, Table 7.3B.2.3.5.1-1a, Table 7.3B.2.3.5.2-0 and Table 7.3B.2.3.5.2-1.\nRAN5 is considering to design exception avoiding testing for REFSENS, which means aggressor UL carriers keep active but MSD = 0. RAN5 would therefore like to get feedback from RAN4 if the IMD requirements (just like for Harmonic interference) shall be seen as exceptions that are applicable only when there is interference overlapping with the victim DL CC. In other words, when carrier frequencies and bandwidths are selected such that there is no overlapping interference the SA requirements apply despite 2UL active.\nIn addition, RAN5 would like to inform that it is using the methods used in RAN4 TR series 37.863 (and its Rel-16 and Rel-17 equivalents) to calculate test frequencies, interference bandwidths to find situations where interference is not overlapping in the case of Harmonic Interference and Harmonic Mixing exceptions.\n\nActions: To RAN4: RAN5 asks RAN4 group to clarify if the EN-DC IMD exceptions are applicable only when the IMD product falls into the victim carrier, and that if SA requirements apply otherwise in the case of 2UL. Also, to clarify the criteria that need to be fulfilled in order for MSD=0 to apply.","secretary_remarks":"","agenda_item_sort_order":489,"ainumber":"5.7","ainame":"\tOutgoing liaison statements for provisional approval","tdoc_agenda_sort_order":135700,"status":"approved","reservation_date":"2021-03-08 12:28:00","uploaded":"2021-03-09 09:51:17","revisionof":"","revisedto":"","release":"Rel-15","crspec":"","crspecversion":"","workitem":[{"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_90_Electronic\/Docs\/R5-211609.zip","group":"R5","meeting":"R5-90-e","year":2021,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0},
