CID 36 and 58 Comments Proposed Change CID 36: The channel can be the same based on the coordinator geographic location. The sentence need to be modify. CID 58: why must each cluster group use a different channel? Coexistence may only require synchronizing dead time. Proposed Change CID 36: Change the sentence to "Each PAN coordinator uses a channel allocated by the SPC” CID 58: change to "may" use a different channel

CID 36 and 58 (continued) Propose Resolution CID 36: Accept in Principle CID 58: Accept Change to "Each PAN coordinator may use a different WPAN channel allocated by the SPC."

CID 53 Comments Proposed Change Sept. 2013 CID 53 Comments Why create a new device type, SPC? The cluster shown is very similar to that shown in the 802.15.4 standard where the "coordinators" are used for each cluster head. If you need some modifications to the cluster do so, but without requiring each cluster grouping to have its own PAN coordinator Proposed Change delete the SPC functionality and modify the coordinator function to set its own channel.

CID 53 (continued) Proposed Resolution Reject Sept. 2012 CID 53 (continued) Proposed Resolution Reject SPC has unique features, only required for TMCTP. SPC is capable of periodically monitoring channels assigned to child-TMCTP coordinators, by efficiently listening to beacons of the descendants which are operating on different channels in the extended superframe including BOP. Ordinary PAN coordinators are not supposed to be able to access the GDB. Therefore, an SPC, which has the capability of access to GDB, obtains the TVWS channel from GDB and then reconfigures it into a number of WPAN channels to assign them to other PAN coordinators in MAC layer (refer to Figures 34ta and 34tb). The periodic channel monitoring function of SPC is more desirable for TVWS band regulatory environments. ETRI
