WINNER II D6.13.12 v1.0Direct communication between user equipments can be imagined in both cases. In the small officeenvironment, two colleagues would like to exchange a file in a meeting room in a peer-to-peer manner. Inthe shopping mall environment, peer-to-peer communication can be driven by the user equipment context,which could sense its direct neighbourhood and initiate a communication with a peer device.Distributed base stations (many antennas, spatially distributed connected to a BS via optical fibre) couldbe used to extend the coverage (for a given quality) as indoor is often a challenging propagationenvironment.Winner APDistributed APPeer to Peercommunication• Over the airnegociation• Self-organisationLocal area deployment• High throughput• Cooperative relayingFigure 2.2: Illustration of hot-spot use of WINNER Local AreaFor this kind of deployment, the LA concept group focuses on the indoor case while the metropolitanconcept group considers outdoor and outdoor to indoor cases.2.3 Example of usage scenarioIn order to illustrate an use case of the WINNER system in context of LA deployment, a typical usagescript is proposed in the following [WIN2D6112]. Each step addresses different aspects that could berelated to the LA proof of concept, therefore the script is followed by a table that decomposes each stepinto the relevant aspects.Both environments (residential – hot spot) that fall within the scope of LA-CG are depicted in thescenario while the major (relevant) implications are also incorporated within the script steps.Main actor: John, male, 18 years oldLocation: Urban area (a city of Europe)Occupation: StudentDate: A day in 20151.
