Every Individual Member organization is obliged to declare to the Partner Organization or Organizations of which it is a member any IPR owned by the Individual Member or any other organization which is or is likely to become essential to the work of 3GPP. Delegates are asked to take note that they are thereby invited: • to investigate whether their organization or any other organization owns IPRs which are, or are likely to become Essential in respect of the work of 3GPP. • to notify their respective Organizational Partners of all potential IPRs, e.g., for ETSI, by means of the IPR Information Statement and the Licensing declaration forms". Antitrust policy Reminder: "I also draw your attention to the fact that 3GPP activities are subject to all applicable antitrust and competition laws and that compliance with said laws is therefore required of any participant of this TSG/WG meeting including the Chairman and Vice Chairman. In case of question I recommend that you contact your legal counsel. The leadership shall conduct the present meeting with impartiality and in the interests of 3GPP. Furthermore, I would like to remind you that timely submission of work items in advance of TSG/WG meetings is important to allow for full and fair consideration of such matters." 3 SA2#151E Meeting report Puneet 4 General (to be decided after the Docs submission deadline) 4.1 Common issues and Incoming LSs 4.2 P-CRs/CRs related to use of inclusive language in 3GPP 5 Pre-Rel-17 Maintenance (excluding all 5G topics) NOTE: FASMO criterion will be strictly enforced.

In this case, the delegate will not accrue the voting rights for the SA2#152E e-meeting. 4. SA2#152E e-meeting will be conducted by e-mail and conference calls. All discussions will be public and conducted via the 3GPP_TSG_SA_WG2_EMEET@LIST.ETSI.ORG mailing list. There is no subscription to this list, people registered for the meeting will be added to the EMEET list at the submission deadline - 10 Aug (2359 UTC) and also at the registration deadline – 15 Aug (2359 UTC). 5. Following CC (Chaired by SA2 leadership) may be organized during SA2#152E e-meeting – CC#1 17 Aug 2022 (Wednesday) 1300 – 1500 UTC CC#2 22 Aug 2022 (Monday) 1300 – 1500 UTC CC#3 23 Aug 2022 (Tuesday) 1230 – 1530 UTC CC#4 25 Aug 2022 (Thursday) 1300 – 1500 UTC CC#5 26 Aug 2022 (Friday) 1230 – 1530 UTC • The objective of these conference calls would be to find a way forward on any controversial topics. They won't be used to discuss/process documents. • These CC during e-meeting will have approval power. • No recording of CC is allowed, like the 3GPP rules for the F2F meeting. • Additional conference calls may be organized during the e-meeting, if necessary. 6. Only tdocs requested and submitted via 3GU before the "Tdocs submission" deadline will be considered during the e-meeting. At this deadline, 3GU closes and no further tdocs can be requested or submitted. 7. Companies are encouraged to use the SA2 DISCUSSION list to provide comments after the submission deadline. It is better to provide consolidated comments. The author may consider those comments and provide a revision (addressing those comments) at the start of the e-meeting. 8. Tdoc numbers for mirror CRs should be requested and documents submitted by the "Tdocs submission" deadline. Revisions of mirror CRs should not be produced until the CR to the earliest release is Approved. New Tdoc numbers will be allocated to the approved revisions at the Final comments deadline. 24 hours grace period after the Final deadline will be provided to the authors to upload/email final approved documents (along with any mirrors CRs, if applicable). 9. Any comments or revisions prior to the start of the e-meeting will not be considered. 10. If the Technical Document (TDoc) is not available by the "Docs submission" deadline, it will be marked as WITHDRAWN. 11. If there are no comments/objections on a document for approval by the "Revision by" deadline, it is APPROVED at that time. 12. Revisions may be proposed until the "Revision by" deadline. Comments in the email will not be automatically considered under revisions, so please provide a revision document with your changes. 13. If there are no comments/objections on a certain revision by the "Final" deadline, it is APPROVED at the final deadline. 14. Any revision of the document can be approved as long as there are no objections. Having concerns/issues is not implicitly considered an "objection". Therefore, please phrase any potential objections clearly. Providing a revision is not implicitly considered as an "objection" to the older revision(s). Please explicitly state if you have an "objection" to a specific revision and/or if there is another (older) revision that you can "accept". 15. Please clearly indicate "[SA2#152E, AI#, S2-22xxxxx] " in the e-mail subject line, when distributing the documents or commenting on the documents for e-mail approval. Everything between the quotation marks shall be shown as an e-mail subject, including the squared brackets. Don't add any other info like the revision number to the e-mail subject. Do not include any other document number in the subject line.  E-mail without the tag "[SA2#152E, AI#, S2-22xxxxx]" will NOT be considered as part of the email approval.  Please DO NOT make changes to the subject line of ongoing e-mails to avoid breaking an e-mail thread.  Email servers from some companies include new tags in the email subject e.g. "[External]" or other characters. This breaks the email thread. Please try to avoid inserting unwanted tags in the email subject.  Please don't forget to indicate Agenda Item number "AI#" according to the Agenda Items shown in the Agenda table. Example: "[SA2#152E, AI#8.1, S2-2299999] Update of references in 23.501" 16.
