2. Results to Assigned Tasks for TGD Update January 10, 2013 Samsung <Seung-Hoon Park et.al.>, <Samsung Electronics>

3. Items to be Agreed • Common communication mode : All • Regulation : Suh-Wook Kim • Simulation scenarios & parameters for MAC : Shannon & Jin • Definition of latency (discovery, data) : Jiny & Ryu • Needs clear model of discovery • Channel model for licensed bands • 700MHz : Shannon & Marco • Refer to 16m EMD (Evaluation Methodology Doc.) : Chan-ho & Marco • Others?: 16p (M2M) :Shannon • Security (Authentication & key management) : Jun-beom • States of the PD : Eldad • Synchronization : Shannon & Kwak • Relative positioning : J.Kim <Seung-Hoon Park et.al.>, <Samsung Electronics>

4. Channel Model • Channel model for public safety • 700 MHz at North America • TETRA (Terrestrial Trunked Radio) already define path-loss models for public safety • Free-space • Bacon : proposed in EPT/DMO PTG 010. designed for use in flat, open areas. • CEPT SE21: proposed in ITU-R Recommendation SM.329-6. • Refer to ETSI TR 102 300-3 V1.3.3 <Seung-Hoon Park et.al.>, <Samsung Electronics>

5. Channel Model • 802.16p (M2M) • No specific channel model • Existing channel model of 16m EMD is reused. • Request to update of ITU-R P.1411 • Rev. 6 is the latest one • “Propagation between terminals located below roof-top height at UHF” is defined for 300-3000 MHz. • Current path-loss in TG8 channel models doc. (DCN12-459-r3) • Assumes the model within street canyons or over roof-tops for cellular model. • For the case of that transmitter is base station and receiver is mobile station. • These models are not applicable to PD-to-PD scenario. <Seung-Hoon Park et.al.>, <Samsung Electronics>

6. 6.2. Synchronization • Candidate text for sub-clause 6.2. • “IEEE802.15.8 may operate in synchronous or asynchronous mode. When IEEE802.15.8 is operating in synchronous mode, a PD shall maintain synchronization among synchronized PDs during the limited time.” • [Comment] Synchronous mode can support of low duty cycling of discovery and high throughput of data transmission, but with more protocol overheads due to network dynamics. Asynchronous mode can support more simple system with low protocol overheads, but the supportable type of PD may be restricted due to high power consumption. <Seung-Hoon Park et.al.>, <Samsung Electronics>

7. 9.5. Simulation scenarios & parameters (MAC) • Scenarios & parameters for just PDs • This sub-clause is described for discovery phase. • Simulation condition <Seung-Hoon Park et.al.>, <Samsung Electronics>

8. 9.5. Simulation scenarios & parameters (MAC) • Scenarios & parameters for just PDs • Performance metric • The number of discovered PAC IDs during simulation time • Time (TX, RX, IDLE) ratio (to assess power consumption) <Seung-Hoon Park et.al.>, <Samsung Electronics>

9. 9.5. Simulation scenarios & parameters (MAC) • Scenarios & parameters for PD links • This sub-clause is described for communication phase (including unicast, multicast, broadcast, groupcast). • Simulation condition <Seung-Hoon Park et.al.>, <Samsung Electronics>

10. 9.5. Simulation scenarios & parameters (MAC) • Scenarios & parameters for PD links • Simulation condition (cont’d) <Seung-Hoon Park et.al.>, <Samsung Electronics>

11. 9.5. Simulation scenarios & parameters (MAC) • Scenarios & parameters for PD links • Performance metric • Areal sum throughput [bps/km2] • PER (Packet Error Rate) • Jain’s fairness index • Latency [sec] <Seung-Hoon Park et.al.>, <Samsung Electronics>

12. 9.5. Simulation scenarios & parameters (MAC) * CW (Contention Window) • Proposed reference system • For calibration and convenience of comparison • Simplified IEEE802.11g • Most of parameters are borrowed from IEEE802.11g • The following condition is proposed for simplicity <Seung-Hoon Park et.al.>, <Samsung Electronics>
