2 Session #64 NRR Working Group Ad Hoc Committee Opening Report November 16, 2009

3 In November 2008, the Working Group has approved the creation of a WG Ad Hoc Committee with the objective of promoting discussion on robustness and reliability Committee reflector and document upload area – – Study the potential interest of the WG to launch a new standardization activity for a highly-reliable and highly- robust system NRR WG Ad Hoc Committee

4 NRR objectives and plan At the session #62 closing plenary, the Working Group had authorized the NRR Ad Hoc Committee to work on draft PAR and top level technical approaches Activities carried out since session #62 No NRR meetings planned at the Interim sessions #63 and #63.5 Technical discussions on the reflector (72 s) 3 Conference calls have been organized Main documents available for review NRR technical report (C80216nrr-08_004r3) Draft PAR and 5 Criteria (C80216nrr-09_033r1)

5 Technical approach Proposed Baseline : –Modification of the OFDMA PHY, MAC and management interfaces –Addressing both fixed and mobile systems –Operation without infrastructure –Support for Mobile Base Station –Provision of resilience capabilities –Provision of reliable path selectivity –Lower duty cycle operation (reduction of energy consumption) –Support for spectrum flexibility below 6GHz –Support for legacy WirelessMAN-OFDMA equipment

6 Technical approach Legacy network Infrastructure NRR NRR network main characteristics - Possible operation without infrastructure - Resilience capabilities - Reliable path selectivity - Lower duty cycle for reducing energy consumption In-coverage NRR network NRR Out-of-coverage NRR network BSRSSS / MSWire link Wireless link

7 Technical approach Legacy network Infrastructure BSRSSS / MSWire link Wireless link Reconfigurable Node

8 Technical approach NRR Network Infrastructure BSRSSS / MSWire link Wireless link Inter-Cell Communications NRR network with loss of infrastructure; -Node reconfiguration -Inter-cell communication

9 Proposed agenda Wednesday, 8: :00 am –Opening and administration Review of the Opening Report Approval of the Agenda Appointment of a secretary Review of the Guidelines for IEEE meetings –Review of the draft PAR –Review of the draft 5 Criteria Wednesday, 1:00 - 6:00 pm –Preparation of the recommendation to the WG –AOB
