4. PHYs and MAC Outline MAC • Superframe structure mode • TDMA access, poll access & contention access • No Superframe structure mode • Poll access & contention access NB PHY UWB PHY EFC PHY • Mandatory • GFSK • ~1Mbps • Mandatory • PPM/BC-GPPM • Non-coherent • 250kbps~10Mbps • Orthogonal code + FSC • Preamble repetition • Pilot sequence • Optional high data rate • Only for in-body • PSSK • 10Mbps~20Mbps • Optional • Differential coherent • DPSK(Differential Phase Shift Keying) • 1Mbps~10Mbps

5. MAC Baseline

6. 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

7. Superframe structure mode B1 B1 B2 • 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. TAP PAP CAP fixed period variable period variable period SD SD = TAP + PAP + CAP

8. Superframe structure mode B1 B1 B2 • 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. TAP PAP CAP fixed period variable period variable period SD SD = TAP + PAP + CAP

9. No Superframe Structure Mode Broadcast Poll message • 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. Contention resolution mechanism to avoid collision Wakeup message

10. Supporting Mechanisms • Emergency handling • Emergency message must be serviced regardless of coordinator state, by emergency channel access, or etc. • Wakeup mechanism • In-band wakeup • Association & network management • Group association • Coexistence mechanism • Coordinator can choose proper coexistence mechanism among optional methods • Reliability • FEC, ARQ or etc. can be supported, when required • Security

23. Electric Field Communication • With EFC, data transmitted by inducing electric-field and capacitive coupling on dielectric material • Human body has about 300~500 times better permittivity than air • Direct Digital Signaling  FSDT (Frequency Selective Digital Transmission) • Quick and easy connection; Intuitive service with privacy & security • No Antenna, less complex, and extremely low power • Perfect candidate for HBC PHY

25. Data Signal Generation • PHY Header/PSDU Generation • 1 symbol : 16-bit × FSC • FSC: Repeated [0 1 ] & SF = 4 • Operation freq. = fCK • Signal bandwidth depends on data rate (C), symbol conversion rate (1/N), and the length of orthogonal code (2L)

26. Rate Indicator • RI uses SFD to indicate data rate: 7 classes • Both PHY header and PDSU transmitted at the same data rate • Provides throughput efficiency, especially for high data rates • May also use the traditional method using Data Rate Field (DRF) in PHY header • One method selected during initial handshaking of two devices • Master device selects the desired method • During initial handshaking, DRF method is used to indicate the data rate  in PHY Header
