RAN WG1 discussed the above issues in RAN WG1#108. For the first question, RAN WG1 would provide the following response: - RAN WG1 has discussed the issue of whether to provide 'correction information' obtained from PRU measurements from LMF to target UEs for UE-based positioning, but RAN WG1 cannot conclude whether to introduce 'correction information' for UE-based positioning in Rel-17. - RAN WG1 has decided no more discussion on 'correction information' obtained from PRU measurements for UE-based positioning in Rel-17. For the second question, RAN WG1 would provide the following response: - In Rel-17, there is no need to support PRU to provide the antenna orientation information to LMF, and thus no need to specify the PRU antenna orientation information.","secretary_remarks":"Noted","agenda_item_sort_order":22,"ainumber":"8.14","ainame":"Enhancement to the 5GC LoCation Services-Phase 2 (5G_eLCS_Ph2)","tdoc_agenda_sort_order":13770,"status":"noted","reservation_date":"2022-03-25 17:03:58","uploaded":"2022-03-28 10:15:39","revisionof":"","revisedto":"","release":"Rel-17","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"RAN WG2","Cc":"RAN WG3, SA WG2","lsoriginalls":"R1-2202912","lsreply":"","link":"https:\/\/www.3gpp.org\/ftp\/tsg_sa\/WG2_Arch\/TSGS2_150E_Electronic_2022-04\/Docs\/S2-2201942.zip","group":"S2","meeting":"S2-150-e","year":2022,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0},
{"name":"S2-2201948","title":"LS from RAN WG2: LS on Positioning in RRC_INACTIVE State","source":"RAN WG2","contact":"Sven Fischer","contact-id":20628,"tdoctype":"LS in","for":"Action","abstract":"RAN WG2 has technically endorsed the attached 'Low Power Periodic and Triggered 5GC-MT-LR Procedures with SDT' for DL-only and RAT-Independent positioning, for UL-only positioning, and for UL+DL positioning. These procedures are analogous to the 'Low Power Periodic and Triggered 5GC-MT-LR Procedures' specified in clause 6.7 of TS 23.273 but making use of the NR Small Data Transmission (SDT) feature in TS 38.300 in RRC_INACTIVE state instead of the LTE EDT feature in RRC_IDLE state in TS 36.300 currently used in clause 6.7 of TS 23.273. RAN WG2 believes that these procedures may be best captured in TS 23.273 as an alternative to Figure 6.7.1-1 when the Event Reports can be sent using NR SDT. Accordingly, RAN WG2 would like to ask SA WG2 whether support can be provided for the attached procedures in TS 23.273 and, if so, to add support to TS 23.273 as part of Release 17. RAN WG2 would also like to inform SA WG2 about the following agreements made: Agreements: Exposure of the RRC state of the UE to the LPP layer of the UE for RRC_INACTIVE UL and DL positioning will not be specified. This does not exclude cross-layer behaviour in implementations. The RRC state of the UE is not exposed to the LMF for INACTIVE UL and DL positioning. RAN WG2 will not make additional effort to make the gNB aware of when to transit the UE to RRC_INACTIVE (left to gNB implementation and RAN WG3 solution). Action: RAN WG2 kindly asks SA WG2 to review the attached 'Low Power Periodic and Triggered 5GC-MT-LR Procedures with SDT', determine whether support can be provided for the attached procedure in TS 23.273 and, if so, to add support to TS 23.273 as part of Release 17.","secretary_remarks":"Responses drafted in S2-2202915, S2-2202974.
