In next-generation wireless networks, device-to-device (D2D) communication represents a feasible way for mobile users to offload their cellular traffic demand without extra costs for deploying additional infrastructure from the network operators. Cellular (e.g., 3GPP LTE) network <bold>assistance</bold> can automate user/service discovery and connection establishment procedures, as well...
With this overview paper, we consider a comprehensive set of technology innovations to (i) dramatically improve the available cellular network capacity, (ii) provide a uniform wireless connectivity experience, and (iii) deliver a higher level of service quality and user satisfaction. To achieve these ambitious goals, we explore the emerging concepts of enhanced spectral reuse via device cooperation,...
In this paper, we consider a wireless cellular network with support for client relay. As such, neighboring clients may cooperate with each other sending uplink data packets. Client relay technique has recently been shown to considerably improve the performance of cell-edge users with poor communication link. We extend our three node client relay system analysis to a more realistic scenario with limited...
