2. Background IMT-Advanced Network Topology proposes multi- hop, mesh and P2P (peer-to-peer) modes 16m SRD required 16m support new services, e.g. real-time gaming or real-time video streaming over high definition screens Existing P2MP possibly does not satisfy the demand of new services –Lower end to end latency –More bandwidth requirement

3. New usage model Wireless Peer to Peer communication P2P: –Traffic from one MS to another MS directly, or multi-hop communication through intermediate RS or MS, bypassing BS Advantages –Low latency –Significantly reduce the traffic burden at BS –Power saving on MS –High spectrum efficiency –High flexibility, reliability

4. Topology of Wireless Peer to Peer communication 16m BS 16m RS 16m MS 16m BS 16m RS 16m MS Data transmission MS communicate via intermediate RS MS communicate directly

5. Wireless communication between MS in trains –Data transmission directly or via MRS between MSs –Only some control messages relayed between BS and RS –Easy to perform handover with less impact on service flow Application scenario 1 Public transportation RS MS BS

6. Application scenario 2 Airport Real-time services, e.g. video gaming, between passengers –Wireless communication between MSs –Lower latency RS MS Departure lounge Airport terminal

7. Application scenario 3 Enterprises RS BS MS Video conferenc e Large coverage, multiple buildings at one site –Optimum solution for enterprise customers –Both internal video or audio services could bypass BS –Less cost for enterprises and new revenue model for operators

8. Business model Peer to peer wireless communication is oriented to services –Only applied to the services designated by operators, e.g. interactive video gaming –Operators can control whether MS is allowed to setup P2P communication Normally, MS are not allowed to setup P2P arbitrarily In some special cases, e.g. emergency, MS may communicate by themselves Operable and administrable –Revenue models of wireless P2P for operators Paid by users initiating services over P2P, e.g. Interactive video gaming Billing could be based on –On-line time –Bandwidth consumption in terms of the bandwidth request/allocation info. –Content supervision Transmission path can be redirected to pass RS or BS

9. Proposed comments on Usage Model 16j Usage Model Document(C80216j-06/015) is regarded as the basis of 16m multi-hop relay usage model It is proposed to add the ‘wireless peer to peer communication’ as a 16m multi-hop relay usage model

10. Proposed comments on Usage Model Text (1) It is proposed to add the following section into the 16m multi-hop relay Usage Model Document x.x Wireless Peer to Peer Usage Model In this usage model RS are deployed in the network to improve coverage, capacity or per user throughput. In this usage model the data transmission may occur between MSs through zero or multiple RS and does not pass through BS. RS deployed in this model could be fixed, nomadic or mobile. Some example application scenarios include: Communication between MS on board moving vehiclesCommunication between MS on board moving vehicles Interactive services among MSs at airportInteractive services among MSs at airport Enterprises internal communicationsEnterprises internal communications

11. Proposed comments on Usage Model Type of routes Replace the first paragraph of the section ‘Type of Routes’ with the following description All data communication can be classified into two categories: one is the data communication between BS and MSs through zero or more RS, and the other is the data transmission between MSs through zero or more RS. In the second case, the data transmission bypasses BS.
