Re: [ipwave] Commenting on the FCC plan

For information,

The FCC plan was to carve out spectrum space for Cellular V2X out of the
ITS 5.9GHz band.

Now there is news about the allocation of ITS frequencies in Europe.

This Decision by EU about the ITS frequencies was released a few days
ago at URL
https://eur-lex.europa.eu/legal-content/EN/TXT/?qid=1602230223168&uri=CELEX:32020D1426

This Decision says a few interesting new things:

- the 5915-5925MHz is for Infrastructure-to-Vehicle communications.
That would mean, my interpretation is, that an RSU (Road-Side Unit)
sending IPv6 RAs would have to put them on that channel, and probably
not on the main control channel 5895-5905MHz, aka CCH, as I was firmly
believing up to now.

- the 5915-5935MHz is for 'urban rail' together with ITS.  There is some
overlap indeed, but they'd expect deployers to figure the overlap out in
different ways at various places, I think.

- most interestingly, in light of the FCC plan, this decision also talks
about 5G and in particular about LTE-V2X (again this term!).  It is said
that ETSI is working on two documents about 'co-channel' and 'adjacent
channel' co-existence methods between ITS G5 and LTE-V2X.  This
Decision's authors expect ETSI documents to be ready by middle of year
2021 or middle of year 2022.

I would like to ask:
- what are the ETSI documents working on co-channel and adjacent-channel
co-existence for ITS and LTE-V2X?
- what is the advancement of the FCC plan about carving out spectrum
space for Cellular V2X out of the 5.9GHZ bands?
