Wendong and All,
I think the wireless control channel mechanism Wendong mentioned is not for inter-network coexistence but for
self-coexistence between different WRAN cells, precisely, for inter-BS coexistence.
I believe there are no existing standards that deal with inter-system coexistence so far.
That's why 19 should cover coexistence mechanisms for dissimilar (or different) systems.
Regards,
Hyunduk

Hyunduk,
Various mechanisms had been proposed. The one in the latest 802.22 draft standard is called "Coexistence Beacon Protocol".

Subject: Re: Standards relevant to 802.19 PARSteve,
There would be certain degree of overlaps among .22 and .19's coexistence work in TVWS, depending on how the scope of .19's new PAR is to be defined.
If .19's new PAR will cover the coexistence of TVWS devices with TV band incumbents, or/and cover the self-coexistence among the TVWS devices, then there will be a strongly similarity to between .19 and .22. Additionally, 802.22 has specified a wireless control channel mechanism to facilitate the inter-network coexistence. As you suggested, .19 and .22 would become similar if .19 also wants to cover this area.
Regards,
Wendong
Shellhammer, Steve wrote:Wendong, Thanks. We need to be clear about the similarity. The following three standards project are for new MAC/PHY to operate in the TVWS 1. 802.22 2. 802.11 TVWS 3. CogNea However, the 19 work is on coexistence of these standards, so they are related but they are for offering wireless protocol in the TVWS where 19 would of course develop coexistence in the TVWS. If the 19 SG considers a wireless control channel then that would be more similar to the three standards project listed above.
