July 2015 Doc: IEEE 802.15-15-0559-00-0008 802.15.8 Architecture The MAC is divided into: MAC data service Data transfer, ACK, CAP, CFP. MAC management service Access to the IB, peering, di-peering, CFP allocation, message pending, network start, scanning, search. both are accessed through respective SAP.

July 2015 Doc: IEEE 802.15-15-0559-00-0008 MAC Service Primitives As described before, communications are passed between the MAC User and MAC Layer by means of service primitives: Request, confirm, indication, response. Submission Slide 12 Hernandez,Li,Dotli ,Miura (NICT)
July 2015 Doc: IEEE 802.15-15-0559-00-0008 Implementation of Service Primitives Submission Slide 13 Hernandez,Li,Dotli ,Miura (NICT)
July 2015 Doc: IEEE 802.15-15-0559-00-0008 Implementation of Service Primitives The question is: how much/long we should invest in defining service primitives for the MAC? The PHYs do not have any (at least now). We propose TG8 implements a basic set of primitives for network synchronization, discovery, peering and communication. We provided some examples for communication, peering, di- peering, passive/active scan. While in course of letter ballot, we will see if we need to add more.
