Mobile Terminal Rely Terminal relay for Coverage extension July 2010 Mobile Terminal Rely Terminal relay for Coverage extension New telecom services Mobile Terminal Relay Architecture Slide 3

Benefits of Mobile Terminal Rely July 2010 Benefits of Mobile Terminal Rely No additional deployment No cost for carrier Most effective when most needed Usually the demand is high when users are dense In terms of both capacity improvement and coverage extension Slide 4

Terminal Rely Protocol Stack July 2010 Terminal Rely Protocol Stack Control Plane User Plane

Benefits of PDCP Tunneling Method July 2010 Benefits of PDCP Tunneling Method Security and security are enforced at the same level No additional trust issue involved Leverage existing QoS provisioning at air interface L1/L2 Limited update to RAN, low complexity No change to the core network Control and configured by carrier network Different from the gateway relay architecture Slide 6
