[{"name":"R5-196967","title":"Proposal for RAN5 basket WI for Rel-16 NR bands and BW extensions","source":"Ericsson","contact":"Ingbert Sigovich","contact-id":28887,"tdoctype":"discussion","for":"Discussion","abstract":"RAN4 have in Rel-16 introduced several work items for new NR bands as well as channel bandwidth extensions for the existing NR bands.\nThe purpose of this paper is to propose a RAN5 basket work item covering all RAN4 Rel-16 work items introducing new NR bands or channel bandwidth extensions for existing bands.\nDiscussion\nTable 2-1 lists the RAN4 Rel-16 work items in the 3GPP work plan [1] introducing new Rel-16 NR bands. Table 2-2 lists the RAN4 Rel-16 work items in the 3GPP work plan [1] introducing extended channel bandwidth to the exiting NR bands.\nIt is expected that there will be an interest to introduce most or all the new bands and channel bandwidth extensions in Table 2-1 and Table 2-2 in RAN5 test specifications. The increase in RAN5 work items will cause overhead in the RAN5 meeting agenda and meeting execution. Having all the new NR band and channel bandwidth extension work items covered by a RAN5 basket work item would enable RAN5 to more efficiently handle CRs for common areas (i.e. like what is done today for common areas for LTE CA).  \nObservation#1: Having all the new NR band and channel bandwidth extension work items covered by a RAN5 basket work item would reduce the number of RAN5 WIs in the agenda and enable RAN5 to more efficiently handle CRs for common areas.\nProposal#1: Create a RAN5 basket work item for RAN4 Rel-16 new bands and channel bandwidth extensions.\nFor RAN4 work items introducing new non-SDL\/SUL bands RAN4 have agreed that all the associated CA or DC configurations shall be included in the relevant RAN4 CA\/DC basket work item and NOT in the NR band work item. This means that RAN5 can include all Rel-16 non-SDL\/SUL CA\/DC configurations associated with the new Rel-16 NR non-SDL\/SUL bands as part of the existing RAN5 Rel-16 basket work item for NR CA and DC; and NR and LTE DC Configurations [2].\nObservation#2: All CA and DC configurations associated with new Rel-16 NR non-SDL\/SUL bands are introduced in RAN4 as part RAN4 CA or DC basket work items.\nProposal#2: RAN5 to include all Rel-16 CA\/DC non-SDL\/SUL configurations associated with the new Rel-16 NR band as part of the existing RAN5 Rel-16 basket work item for NR CA and DC; and NR and LTE DC Configurations [2].\nFor RAN4 work items introducing new SDL and SUL bands RAN4 may include associated CA configurations in the SDL\/SUL band work item (e.g. NR supplementary DL band n29 includes CA_n29A-n66A). RAN5 CRs introducing such CA configuration need to use the RAN5 WI code covering the SDL\/SUL CA configuration. However, to get a complete list of the Rel-16 CA\/DC configurations it is proposed to also list the SDL\/SUL CA configurations introduced in RAN4 non-basket work items in the Rel-16 CA\/DC work item in [2] work plan. To indicate that the CA\/DC configuration is introduced by another RAN5 work item a comment can be added to the CA\/DC work plan.   \nObservation#3: RAN4 work items introducing new SDL and SUL bands RAN4 may also include associated CA configurations. \nProposal#3: RAN5 to include all Rel-16 CA\/DC SDL\/SUL configurations associated with the new Rel-16 NR SDL\/SUL band as part of the existing RAN5 Rel-16 basket work item for NR CA and DC; and NR and LTE DC Configurations [2]. A comment should be added indicating the SDL\/SUL CA configuration that are introduced by any other RAN5 work item.","secretary_remarks":"","agenda_item_sort_order":8,"ainumber":"4.2","ainame":"\tGeneral Discussion Papers","tdoc_agenda_sort_order":696700,"status":"noted","reservation_date":"2019-09-03 11:42:46","uploaded":"2019-09-03 11:47:53","revisionof":"","revisedto":"","release":"","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/TSG_RAN\/WG5_Test_ex-T1\/TSGR5_84_Ljubljana\/Docs\/R5-196967.zip","group":"R5","meeting":"R5-84","year":2019,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0}]
