[{"name":"R5-240303","title":"New WID on UE Conformance - Further RF requirements enhancement for NR and EN-DC in frequency range 1","source":"Huawei, Hisilicon, China Telecom","contact":"Yuxin Hao","contact-id":82979,"tdoctype":"WID new","for":"Endorsement","abstract":"3GPP TSG RAN WG4 has created Rel-18 work item for Further RF requirements enhancement for NR frequency range 1 (FR1). Requirements for following aspects are introduced under this WI:\n1.\t4Tx RF requirements for CPE\/FWA\/vehicle\/industrial devices for non-CA case\na)\tTx requirements, including MPR, configured output power, etc. Both UL-MIMO and TxD are considered for the 4Tx architecture.\nb)\tRx requirements, including REFSENS, ACS, etc. Both UL-MIMO and TxD are considered for the 4Tx architecture.\nc)\tNew capability signalling for 4Tx-TxD per-band per-band combination.\n2.\t8Rx requirements for CPE\/FWA\/vehicle\/industrial device, including core requirements and performance requirements\n3.\tMSD improvement for inter-band CA\/EN-DC\/DC combinations\na)\tSpecific lower-MSD requirements for inter-band CA and EN-DC configurations\nb)\tNew capability signalling for lower MSD\nThe core part has been 100% completed and the Performance part has been 85% completed at RAN#102 (December 2023). It\u2019s time for 3GPP TSG RAN WG5 to start working on the corresponding conformance testing part to meet the industry interest.\n4\tObjective\n4.1\tObjective of SI or Core part WI or Testing part WI\nThe objective of this work item is to define the conformance testing aspects for the Rel-18 Further RF requirements enhancement for NR and EN-DC in frequency range 1 WI, including RF, RRM, Demod and Protocol areas.\nFor enhancements for 4Tx, example bands considered in core WI are n41, n77\/n78, n1.\nFor enhancements for 8Rx, example bands considered in core WI are n41, n77\/n78, n79, n7.\nIn conformance test WI, example bands and example configurations would be selected from the above list based on industry interest to complete the structure of new RF test cases. \nFor lower-MSD improvement, RAN5 needs to decide whether the test framework is per-band-combination basis or general for all band combinations. If the test framework is decided as per-band-combination basis, example band combination(s) would be selected based on industry interest to complete the relevant RF work.","secretary_remarks":"","agenda_item_sort_order":7,"ainumber":"4.1","ainame":"\tNew Work Item proposals - for intro only","tdoc_agenda_sort_order":3030,"status":"revised","reservation_date":"2024-06-02 09:12:30","uploaded":"2024-02-08 03:10:53","revisionof":"","revisedto":"R5-241463","release":"Rel-18","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"","lsreply":"","link":"https:\/\/www.3gpp.org\/ftp\/tsg_ran\/WG5_Test_ex-T1\/TSGR5__102_Athens\/Docs\/R5-240303.zip","group":"R5","meeting":"R5-102","year":2024,"uicc_affected":"","me_affected":"","ran_affected":"","cn_affected":"","clauses_affected":"","crsinpack":null,"crsinpacknumber":0}]
