I think that we need to remember that in some cases CCA is necessary for minimal, such as shared slots, but also when there are multiple instances of 6tisch being used by non-coordinated entities.
Regardless, "In the TSCH mode, backoff is calculated in shared links, so the CSMA-CA aUnitBackoffPeriod is not used.” The CCA mode may be enabled for TSCH by the TSCH-MODE.request where the TschMode may be enabled and also the TschCca may be enabled Pat Kinney Kinney Consulting LLC IEEE 802.15 WG vice chair, SC chair ISA100 co-chair, ISA100.20 chair O: +1.847.960.3715 [email protected] <mailto:[email protected]> On 22, Nov2016, at 5:57, Maria Rita PALATTELLA <[email protected]> wrote: Xavi, sure, we can add CCA among the terms. Pascal, about the last call for the terminology draft, I believe we can go for it. Maybe we only need to check first if there are new terms coming from the 6P and SF0 drafts (but I doubt, because we checked already last time), or from the latest security related drafts (draft-vucinic-6tisch-minimal-security, and draft-richardson-6tisch-dtsecurity-secure-join). @Malisa and Michael: do you see any term missing? you would like to add?

Also: as discussed at the IETF meeting, we also need to trigger last call for the terminology draft, which will cause minimal to be held for publication otherwise. Maria-Rita, do you think we are ready for that? Take care, Pascal From: 6tisch [mailto:[email protected]] On Behalf Of Xavi Vilajosana Guillen Sent: mardi 22 novembre 2016 11:58 To: Maria Rita PALATTELLA <[email protected]>; tisch <[email protected]> Subject: [6tisch] Adding CCA to the terminology draft Dear Maria Rita, I would like to suggest adding the following definition to the terminology draft so we can point to it from minimal. CCA: Clear Channel Assessment. Mechanism defined in <xref target="IEEE802154-2015"/>, section 6.2.5.2. In a TSCH network, CCA can be used to detect other radio networks in vicinity. Nodes listen before sending to detect other ongoing transmissions. Because the network is synchronized, CCA cannot be used to detect colliding transmission within the same network. let me know if this is possible. thanks!
