The core WI has a rel17 WI and a Rel18 WI.

Corresponding UE capability CR was introduced to allow UE to advertise in its UE capability info regarding support for PMCH BW of 40\/35\/30 PRBs_x000D_\nAs seen in the above snippet, the objective of the part1 WID was to introduce the necessary 36.331 and 36.306 signaling to enable the introduction of new band\/bandwidth and corresponding RF requirements for LTE based 5G broadcast. _x000D_\nRel18 part2 WID (New bands and bandwidth allocation for LTE based 5G terrestrial broadcast - part 2) (UID 920071) was introduced to add the new band (n107, n108)\/bandwidth (6\/7\/8 MHz) along with RF requirements._x000D_\nThere are 2 options for introducing the corresponding RAN5 conformance WI._x000D_\n_x000D_\nOption1: RAN5 to introduce 2 separate WI: Rel17 part1 followed by a Rel18 part2_x000D_\nOption2: RAN5 to introduce a single Rel18 WI which to address the objectives of both the Rel17 and Rel18 core WI._x000D_\n_x000D_\nOption1 will allow a 1:1 correspondence with the core WI.

But the bandwidth introduced for the new bands n107 and n108 only have 6\/7\/8 MHz bandwidth. _x000D_\n_x000D_\nSo the 10MHz PMCH demod requirements defined in the Rel16 WI cannot be directly applied to the n107\/n108 bands. Clarifications are needed from Ran4 on how to test the PMCH demodulation requirements for n107\/n108 bands. _x000D_\n_x000D_\nOur suggestion is to include all these Rel14\/Rel16 changes and discussion as part of the same Rel18 work plan since the contents of all these WI are inter-dependent. _x000D_\n_x000D_\nProposal 2: Include the relevant SIG\/RF\/Demod related changes introduced in Rel14\/Rel16 core WI in the same Rel18 RAN5 WI.","secretary_remarks":"","agenda_item_sort_order":18,"ainumber":"4.5.4","ainame":"\tOther open issues from joint sessions - original A.I. retained","tdoc_agenda_sort_order":33580,"status":"noted","reservation_date":"2024-10-05 20:05:57","uploaded":"2024-05-25 18:11:16","revisionof":"","revisedto":"","release":"Rel-18","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__103_Fukuoka\/Docs\/R5-243358.zip","group":"R5","meeting":"R5-103","year":2024,"uicc_affected":"","me_affected":"","ran_affected":"","cn_affected":"","clauses_affected":"","crsinpack":null,"crsinpacknumber":0}]
