Introduction
The merged MAC proposal targets all BAN applications and meets all TG6 functional requirements.
The coordinator can operate in either of the two modes Superframe structure mode
TDMA access period (TAP): Scheduled TDMA access Poll access period (PAP): Scheduled Poll access Contention access period (CAP)
No Superframe structure mode Unscheduled Poll access Contention access

Superframe structure mode
The format of the Superframe is defined by the coordinator.
A Superframe consists of three periods. Contention Access Period (CAP) : mandatory TDMA Access Period (TAP) : optional Poll Access Period (PAP) : optional
The duration of TAP is fixed over subsequent Superframes. The duration of PAP and CAP may vary over subsequent frames, but
always, PAP+CAP = SD – TAP.

Superframe structure mode
Two broadcast messages B1 and B2 are transmitted to manage network connection, device association, resource reservation, Superframe description etc.
B1 defines the duration of TAP and SD. It also defines the slot structure in TAP and responsible for clock synchronization of TAP devices.
B2 defines the length of the CAP and used for device association and resource reservation. B2 messages are sent without using the contention access.
Optionally, the Superframe can have an Inactive Period (IP). Then, SD = TAP+PAP+CAP+IP. During the Inactive Period, the coordinator may enter a sleep mode.

No Superframe Structure Mode
Coordinator does not define Superframe structure to coordinate and manage device access
Device transmit data frames using Unscheduled Poll access Suitable and preferred when data transfer of only few implant devices are required Suitable for meeting the delay and jitter requirements of multimedia streaming traffic
• Device can transmit data frames with Contention Access as well The coordinator may occasionally transmit a Wakeup/Broadcast poll
message. A wakeup message is sent to wakeup the implant device(s) to start a data session Broadcast Poll message is used for device connection and network formation.
