[{"name":"R5-210277","title":"Discussion paper for RRC Segmentation in Rel-16 RACS","source":"Qualcomm CDMA Technologies","contact":"yogesh tugnawat","contact-id":63855,"tdoctype":"discussion","for":"Discussion","abstract":"Rel-16 WI for RACS introduced the feature to send RRC message in segments if the message is larger than maximum supported size of a PDCP SDU (9k in NR, 7k LTE). Below are the core spec requirements which creates challenges in conformance testing for a reliable and consistent outcome.\n\nPossible Solutions:\nProposal-1 - Testing using PICS\/PIXIT Declaration for UE Capability Information testing\nBelow PICS have been defined in RAN5#89-e [1] and would allow to test various scenarios related UE's reliability of UECapabilityInformation \n1. PC_5GC_RACS - This is the NAS capability for UE to support RACS\\URCID\n2. pc_NR_UL_Segmentation - UEs supports of segmentation of UECapabilityInformation message, IF size > maximum supported size of a PDCP SDU\nBelow scenarios needs to be considered - \n2.2.1. NR TC 8.1.5.1.1 (and EN-DC TC 8.2.1.1.1) will need to be updated to handle the potential use of several RRC segments by the UE under test, \n2.2.2 Possible Separate Test Cases for-\nA.\trrc-SegAllowed present AND UE is  queried for the Maximum Capabilities i.e. without any band filter, contents not checked\nB.\trrc-SegAllowed Not Present AND UE is  queried for the Maximum Capabilities i.e UE shall not segment\nBased on TS38.331 cl 5.6.1,3 and 5.6.1.4, 2.2.2 above might not be testable due to UE specific implemetation\n\nProposal-2 - Introduce Test Function\\Command to test UL segmentation\nDespite the test scenarios allowing UL segmentation and UE also support segmentation, it is still not guaranteed that UL segmentation will happen. In order to test UL segmentation aspects alone, highlighted part needs to be satsfied in below condition -\nR16 UE AND NW supports UL Segmentation at RRC ( i.e. rrc-SegAllowed) THEN,  IF (UE\u2019s size of UL RRC Capability Message> 9K),THEN  UL Segmentation happens\nA test function\\command can be defined which will set the UE to construct UECapabilityInformation message from a predefined dummy message (which has no context to UE's real capabilities) to be processed by its RRC layer for transmission to lower layers thus always satisfying the above condition, each of ULDedicated Message Segment can be verified for its relevant IE's. This procedure can be made optional for UE's who are able to achieve UL segmentation in Proposal-1, test scenario 1 (also below)\n1.\trrc-SegAllowed present AND UE is  queried for the Maximum Capabilities i.e. without any band filter\nAs a proposal, a draft CR to introduces this test test function in TS 38.509 is available in R5-210372, revised WID to add TS 38.509 is in R5-210278, and a model test case to exercise the test function to test UL segmentation is introduced in TS 38.523-1 in R5-210370\n\n\tConclusion and Way Forward:\n1. Proposal 1 (2.2.1)  and Proposal 2 are both critical for proper testing of RRC UL segmentation feature","secretary_remarks":"","agenda_item_sort_order":694,"ainumber":"6.3.20.","ainame":"\tDiscussion Papers \/ Work Plan \/ TC lists","tdoc_agenda_sort_order":2770,"status":"revised","reservation_date":"2021-02-02 00:52:02","uploaded":"2021-03-06 17:31:14","revisionof":"","revisedto":"R5-211324","release":"Rel-16","crspec":"","crspecversion":"","workitem":[{"winame":"RACS-UEConTest"}],"crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"","lsreply":"","link":"https:\/\/www.3gpp.org\/ftp\/TSG_RAN\/WG5_Test_ex-T1\/TSGR5_90_Electronic\/Docs\/R5-210277.zip","group":"R5","meeting":"R5-90-e","year":2021,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0},
