October 2020 doc.: IEEE 802.11-20/1602r5 Open: 2 Comments marked for acceptance w/no text changes CIDs: 5 and 7 Comment The sentence states that there is a terminal type (an UE and a STA). However, there is also a separate STA terminal type (see Figure3), so there are really two terminal types. C P C L Proposed Change Modify the scope to state that there are two terminals types: 1) a UE and a STA, 2) a STA Change the text to read "RAN level (layer 2) interworking and CN level (layer 3 and above) interworking [2-4]." T 6 2.223 It may help to explain RAN level and CN level a little more T 7 3.129 Agenda Slide 20 Joseph Levy (InterDigital)

November 2020 doc.: IEEE 802.11-20/1602r5 From 11-20/0013r5: 2.2 Scope This report covers an interworking reference model, necessary functionalities and specific procedures that 19 allow WLAN access networks to interwork with 3GPP 5G network. Two types of interworking reference 20 models are considered: a tightly coupled model and loosely coupled model. The interworking reference model consists of terminal part (an UE and a STA), access networks (3GPP and WLAN), 3GPP 5G core network and data network as shown in Figure 1. Two access networks are connected to server via 3GPP 5G core network. 3GPP access network and 5G core network are defined in 3GPP specification and WLAN access network considered is defined in the IEEE 802 network reference model of IEEE 802.1CF-2019 [18]. From 11-20/0013r7: This report considers two types of interworking reference model: a tightly coupled model and loosely coupled model that connects different types of terminal individually. The architectural models, necessary functionalities and specific procedures that allow WLAN access networks to interwork with 3GPP 5G core network services are discussed for both the trusted as well as untrusted case as defined in TS 23.501 comprising integrated or stand-alone implementations of WLAN and 3GPP 5G access networks and terminals. The high level interworking reference model consists of terminal, access networks, 3GPP 5G core network and a data network as shown in Figure 1. In Figure 2, it further entails the functions within each entity. There are two terminal types: 1) a UE and a STA, 2) a STA. 3GPP access network and 5G core network are defined in 3GPP specification [8, 16] and WLAN access network considered is defined in the IEEE 802 network reference model of IEEE 802.1CF-2019 [18]. CID 5 Agenda Slide 21 Joseph Levy (InterDigital)

November 2020 doc.: IEEE 802.11-20/1602r5 CID 7 From 11-20/0013r5: 3.1 WLAN Interworking types (last paragraph) 3GPP LTE-based (4G) cellular system has specified both RAN level interworking and CN level interworking [2-4]. The RAN level interworking belongs to tightly coupled interworking model and the CN level interworking belongs to loosely coupled interworking model. However, 3GPP 5G system has allowed WLAN access as a non-3GPP Radio Access Technologies (RAT) that can be directly connected to 5G Core Network (CN) via the N3IWF (Non-3GPP Interworking Function) or the TNGF (Trusted Non-3GPP Gateway Function) depending on whether the WLAN is trusted or untrusted [8]. Therefore, the CN level interworking model in the 5G system is different from the LTE system. From 11-20/0013r7: 3GPP cellular system has specified both RAN level (layer 2) interworking and CN level (layer 3 and above) interworking [2-4]. The RAN level interworking belongs to the tightly coupled interworking model and the CN level interworking belongs to the loosely coupled interworking model. However, 3GPP 5G system has allowed WLAN access as a non-3GPP Radio Access Technologies (RAT) that can be directly connected to 5G Core Network (CN) via the N3IWF (Non-3GPP Interworking Function) or the TNGF (Trusted Non-3GPP Gateway Function) depending on whether the WLAN is trusted or untrusted [8]. Therefore, the CN level interworking model in the 5G system is different from the LTE system. Agenda Slide 22 Joseph Levy (InterDigital)

November 2020 doc.: IEEE 802.11-20/1602r5 Motions (cont.) Motion 5: Move to accept resolutions on 11-20-1602r4 slides for CID 5 and 7 from 11-20- 0013r7 and add them to 11-20-1262r5. With editorial privileges given to the AANI Chair. Moved: Peter Ecclesine Second: Stuart Kerry Result: Y:20 N:0 A:13 DNV:45 Agenda Slide 23 Joseph Levy (InterDigital)

October 2020 doc.: IEEE 802.11-20/1602r5 Open: 2 Similar General Comments CIDs: 72 and 73 Comment In this TR, there is no discussion and evaluation result to show WLAN can support high rate to meet the performance of 5G network vision in the low mobility scenario. And in Table 5, it is also mentioned that 802.11ax MAC can not support 3GPP GBR and delay critical GBR service In this TR, there is no discussion and evaluation result to show WLAN can support high rate to meet the performance of 5G network vision in the low mobility scenario. Moreover, there is no discussion in 3GPP on the interworking between NR and WLAN. Proposed resolution: Reject Comments request additional content that is out of scope of this report and no text proposal has been provided. Agenda Slide 24 Joseph Levy (InterDigital)

October 2020 doc.: IEEE 802.11-20/1602r5 CIDs: 72 and 73 Discussion: Should a reference or summary of the performance of the 802.11 RAT (Radio Access Technology) be provided in this report? If yes - who will provide a text contribution for the report? If no - suggest the comment should be resolve: Reject Comments request additional content that is out of scope of this report and no text proposal has been provided. Reject These comments are not relevant within the scope of this report. Agenda Slide 25 Joseph Levy (InterDigital)

November 2020 doc.: IEEE 802.11-20/1602r5 Motions (cont.) Motion 6: Move to reject CIDs 72 and 73 with the reason: these comments are not relevant within the scope of this report. Add these resolutions to 11-20- 1262r5. Moved: Peter Ecclesine Second: Hyun Seo Oh Result: Y:16 N:0 A:10 DNV:51 Agenda Slide 26 Joseph Levy (InterDigital)

October 2020 doc.: IEEE 802.11-20/1602r5 Open: CID 69 - Technical w/no text changes Comment This technical report has several inaccuracies, misinformation and missing details on the WLAN and 5G interworking as defined by 3GPP in Release 15 and 16. There is major lack of technical accuracy and technical clarity in section 3 and 4. The report is misleading in terms of what functions need to be supported within WLAN to enable interworking. The set of new functions/protocols identified in section 5 to be implemented within WLAN do not accurately represent what needs to be supported in WLAN to enable interworking and are quite misleading. Overall, due to the technical inaccuracies as well as misinformed and misguided nature of the report, this technical report does not serve the purpose of providing a reliable reference for stakeholder/groups interested in enabling WLAN interworking with 5G networks. Agenda Slide 27 Joseph Levy (InterDigital)

October 2020 doc.: IEEE 802.11-20/1602r5 Open: CID 71 - Technical w/no text changes Comment This document has too many issues and misleading information on overall WLAN & 5G integration options, architectures and solutions. It would be very confusing and concerning to publish such a report. Also, please note that there is a parallel related "5G & WLAN RAN Convergence" work at WBA. It is important that we are aware of what is already happening in this space rather than proposing something disregarding them. Agenda Slide 28 Joseph Levy (InterDigital)

October 2020 doc.: IEEE 802.11-20/1602r5 Open: 3 Similar General Comments CIDs: 68, 70, and 80 Comment This technical report does not accurately reflect 5G and WLAN interworking as defined in 3GPP. It is misguided in terms of the new functionality being asked to be added in the WLAN STA and AP to support interworking. It is difficult to understand the report and how to use it to enable the support for interworking with 5G within the WLAN domain. The comment submitter will provide a separate submission on the 5G and WLAN interworking. There are several inaccuracies and misinformation in this technical report related to WLAN integration and interworking with 5G. The TSN architecture as shown for the 5G and WLAN converged network and also for the WLAN only network is incorrect. The recommendations made at the end of the report do not accurately represent what is needed to enable interworking Agenda Slide 29 Joseph Levy (InterDigital)
