[{"name":"R5-205123","title":"New WID on UE Conformance Test Aspects for NR Positioning Support","source":"CATT","contact":"Xiaozhong Chen","contact-id":50266,"tdoctype":"WID new","for":"Endorsement","abstract":"Justification\nThe 3GPP NR radio-technology is uniquely positioned to provide added value in terms of enhanced location capabilities. The operation in low and high frequency bands (i.e. FR1 and FR2) and utilization of massive antenna arrays provides additional degrees of freedom to substantially improve positioning accuracy. The possibility to use wide signal bandwidth in low and especially in high frequency bands brings new performance bounds for user location for well-known positioning techniques based on OTDOA and UTDOA, Cell-ID or E-Cell-ID etc., utilizing timing measurements to locate a UE. The recent advances in massive antenna systems (massive MIMO) can provide additional degrees of freedom to enable more accurate user location by exploiting spatial and angular domains of propagation channel in combination with time measurements.\nThe objective of the parent work item is to specify solutions to enable RAT dependent (for both FR1 and FR2) and RAT independent NR positioning techniques while considering E911 (e.g. floor level) and commercial requirements for horizontal and vertical positioning accuracies according to TR38.855. The specification work in the parent work item except the performance parts is finished. Standardized conformance testing specification is required for commercial use on feature NR Positioning Support.\n\n\tObjective\nObjective of SI or Core part WI or Testing part WI\nThe objective of this work item is to define the UE conformance requirements corresponding to WID on NR Positioning Support. This work item will cover signalling and RRM conformance test specifications aspects for NR Positioning Support including the Applicability, Test Environment, Initial Conditions, Test Procedure, Message Exceptions, Test Setup, Connection Diagram, etc.","secretary_remarks":"","agenda_item_sort_order":7,"ainumber":"4.1","ainame":"\tNew Work Item proposals - for intro only","tdoc_agenda_sort_order":51230,"status":"revised","reservation_date":"2020-10-21 02:43:12","uploaded":"2020-10-30 06:36:12","revisionof":"","revisedto":"R5-206247","release":"Rel-16","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_89_Electronic\/Docs\/R5-205123.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}]
