[{"name":"R5-205917","title":"Discussion paper on test case structure for CA PDSCH Demodulation test cases","source":"Qualcomm Austria RFFE GmbH","contact":"Vijay Balasubramanian","contact-id":84569,"tdoctype":"discussion","for":"Endorsement","abstract":"RAN4 has already endorsed draftCR introducing requirements for 2Rx and 4Rx CA PDSCH Demodulation scenarios. [3] and [4] are the CR to 38.101-4 submitted in ongoing RAN4 meeting. \nAs seen in these CRs, RAN4 is defining a single section for 2Rx CA requirements which covers duplex mode (FDD, TDD, FDD+TDD), CA capability (intra-band contiguous, inter-band, intra-band contiguous), number of NR CC in a single section. Similarly 4Rx CA requirements are defined in another section. From RAN5 test case structure point of view, these are some of the options.\nOption1:\nHave a single test clause similar to RAN4 defined requirements; one for 2Rx and another for 4Rx. This approach is not suitable since the same clause needs to be updated as band combos with higher number of CC gets introduced. Also it can\u2019t handle CA modes where UE supports 2Rx on one CC and 4Rx on another CC.\nOption2:\nSplit based on duplex mode keeping CA capability, number of NR CC, 2Rx\/4Rx under single sub clause. Below example elaborates on this approach.\n\u2022\tFDD CA \no\tCovers any number of CC\no\tCovers all CA capability (intra-band contiguous, intra-band non contiguous, inter-band)\no\tCovers 2Rx only, 4Rx only, combination of 2Rx and 4Rx CC\n\u2022\tTDD CA \no\tSame as FDD CA\n\u2022\tTDD FDD CA\no\tSame as FDD CA\no\tCovers TDD FDD CA with TDD Pcell\no\tCovers TDD FDD CA with FDD Pcell\nOption3:\nSplit based on duplex mode and number of NR CC keeping CA capability and 2Rx\/4Rx under single sub clause.\nBelow example elaborated on this approach.\no\tFDD CA (2DL CA) \no\tFDD CA (3DL CA)\no\tFDD CA (4DL CA)\no\tTDD CA (2DL CA)\no\tTDD CA (3DL CA)\no\tTDD FDD CA\no\tTDD FDD CA with TDD Pcell (2DL CA)\no\tTDD FDD CA with TDD Pcell (3DL CA)\no\tTDD FDD CA with FDD Pcell (2DL CA)\no\tTDD FDD CA with FDD Pcell (3DL CA)\nBetween option2 and option3, option3 is more scalable for future revisions as more band combos with higher number of CC gets introduced.\nProposal1: Endorse option3 to structure the CA PDSCH Demodulation test cases in 38.521-4 spec.","secretary_remarks":"","agenda_item_sort_order":353,"ainumber":"5.3.25.7","ainame":"Discussion Papers \/ Work Plan \/ TC lists","tdoc_agenda_sort_order":59170,"status":"noted","reservation_date":"2020-10-30 09:59:56","uploaded":"2020-10-31 08:39:53","revisionof":"","revisedto":"","release":"Rel-16","crspec":"","crspecversion":"","workitem":[{"winame":"NR_perf_enh-UEConTest"}],"crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"","lsreply":"","link":"https:\/\/www.3gpp.org\/ftp\/TSG_RAN\/WG5_Test_ex-T1\/TSGR5_89_Electronic\/Docs\/R5-205917.zip","group":"R5","meeting":"R5-89-e","year":2020,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0}]
