Background
• IMT-Advanced Network Topology proposes multihop, 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
Application scenario 1
Public transportation
• 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 2
Airport
• Real-time services, e.g. video gaming, between passengers
– Wireless communication between MSs
– Lower latency

Application scenario 3
Enterprises
• 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 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 vehicles
• Interactive services among MSs at airport
• Enterprises internal communications
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.
