Two options are being considered for MT-EDT: a. MT DL data is sent in a DL message in response to random access preamble. b. MT DL data is sent in Msg4 during random access procedure. The following agreements have been reached in RAN WG2: - For both UP and CP solutions, an MT-EDT indication is needed in the S1 paging message to eNB. It is up to RAN WG3 to decide how such indication is provided to the eNB. - RAN WG2 assumes that MME initiates MT-EDT. - It is up to eNB to use MT-EDT based on e.g., UE capability. - RAN WG2 assumes that DL data information is needed from S-GW\/SCEF to the MME to assist MME to initiate MT-EDT. Action: RAN WG2 kindly asks RAN WG3, SA WG2, CT WG1 and CT WG4 to take the above information into account in their work regarding MT EDT in Rel-16 and provide feedback if any.","secretary_remarks":"Response drafted in S2-1907613.

RAN WG3 has considered to introduce an explicit MT-EDT indicator in S1 Paging message from MME to inform eNB about possibility to initiate MT-EDT session. However, some companies stressed the fact that this indicator may not be sufficient to set up MT-EDT and that having information about DL data size in S1 paging would help the eNB to decide more precisely if MT EDT should be triggered. RAN WG3 assumes that in any case the eNB needs to be able to fallback to non-EDT operation (e.g. at least depending on propagation conditions), and also that frequent occurrence of such fallback would not be desirable. Therefore, RAN WG3 would appreciate feedback from RAN WG2 on whether RAN WG2 would see benefit in MME providing the data size in the S1 paging message.","secretary_remarks":"Postponed.","agenda_item_sort_order":54,"ainumber":"6.","ainame":"RAN Rel-16 alignment - MT-EDT","tdoc_agenda_sort_order":25370,"status":"postponed","reservation_date":"2019-06-10 18:36:16","uploaded":"2019-06-12 11:37:53","revisionof":"","revisedto":"S2-1908649","release":"Rel-16","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"RAN WG2","Cc":"SA WG2, CT WG1, CT WG4","lsoriginalls":"R3-193156","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/tsg_sa\/WG2_Arch\/TSGS2_134_Sapporo\/Docs\/S2-1906876.zip","group":"S2","meeting":"S2-134","year":2019,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0},
