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

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

Data transmission

MS communicate via intermediate RS

MS communicate directly

• 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

• 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

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

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

Proposed comments on Usage ModelText (1)

•It is proposed to add the following section into the 16m multi-hop relay Usage Model Document

Proposed comments on Usage ModelType of routes

• Replace the first paragraph of the section ‘Type of Routes’ with the following description

All data communication can be classified into two All data communication can be classified into two categories: one is the data communication between BS and categories: one is the data communication between BS and MSs through zero or more RS, and the other is the data MSs through zero or more RS, and the other is the data transmission between MSs through zero or more RS. In the transmission between MSs through zero or more RS. In the second case, the data transmission bypasses BS.second case, the data transmission bypasses BS.
