Re: [802.19] Final candidate document for 3GPP LAA Workshop



Thanks Roger,

I seems to me that LAA is choosing LBT cat 4, irrespective of the targeted scenario. Meaning that even if there are some issues to enable LBT with specific implementation (RRH) in some scenarios, LBT still has to be used.

Do you want to clarify that this is a correct assumption: that LBT is always used, with a single mode of operation ?

Laurent,

The key point is that the deployment scenarios may result in obstacles to incorporating LBT. The scenarios that were evaluated are the ones in which LBT is most easily implemented. The intention is to ask for information showing how LBT works in the context of the carrier-aggregated deployment.

Hi Roger,

I also have questions about this part on macrocell scenarios.

I don’t see what is the intent of this section, having in mind that the concerns that we should raise relate to coexistence with 802.11, rather that feasibility of the original scenarios.

Could you clarify your intention.. maybe I missed the point.

Best

Laurent

Woon-Hau,

I fully agree that names of individuals and companies should be stricken from slides 44 and 50. Likewise, on page 3, the text "Approved by IEEE 802 EC" should be deleted.

Regarding the macrocell slides (44-49), I believe they are inquiring about the level of detail that has been simulated and would not be taken as overly aggressive. If we were to worry that "3GPP may not take it too well if they are told that there are problems with their scheme," then I think we would need to revisit much of slides 3-43 as well.

Regards,

Roger

Hi Andrew,

Thank you for putting in so much effort into this. Just two comments:

On page 44 and 50, there are names and names of companies. As this is
a presentation by IEEE 802, no names or companies should be present,
and the whole slide deck should be presented by one single person in a
coherent way.

Following the above comment, the sections from slides 44 to 53 may
distract the presentation from its original message. I would suggest
that these slides be used as backup, and only presented if time
allows. While I totally agree with Roger's concern that there may be
feasibility issues with LAA in macro cell scenarios, it may be
counter-productive to state them here. I suspect that 3GPP may not
take it too well if they are told that there are problems with their
scheme in an official IEEE 802 presentation.

As for the testbed slides, it may be a tad early to present this. The
whole presentation has a message of "Let's work together on LAA",
while the testbed slides are on what to do AFTER they've agreed to
work with us. Also, the testbed slides also sits more on the
compliance side of things, and would probably be more suitable for
presentation by WFA than IEEE 802.

Just my 2 pence, we can discuss this during the telco today.

G’day all

 

I have created a final candidate document for consideration by the IEEE 802.19 WG l tomorrow as IEEE 802’s submission to the 3GPP LAA Workshop in late August.

·         See 19-15-0069-00

It consists of multiple parts

·         Slide 1 is the title page

·         Slide 2 is a short summary  of the entire document

o   It is new material, as promised last week

o   It focuses on the need for collaboration to solve a joint problem

·         Slides 3-43 is the presentation that we have been refining since the Hawaii plenary

o   Slide 4 is the ExSum

o   Slide 42 is the Conclusion, which is almost the same as the ExSum

o   Slide 43 is a backup (with animation)

·         Slides 44-49 is Roger Marks’ presentation

o   Roger, I did some editorial stuff, including a new title – please feel free to reject anything I did

·         Slides 50-53 is Ben Lampert’s presentation

o   Ben, I did some editorial stuff, including a new title – please feel free to reject anything I did

I believe we have caught all the significant issues over the last few weeks. I suggest we approve the deck on the understanding that any outstanding editorial issues can be  handled during the IEEE 802 EC approval process.
