Downlink beamforming techniques with low signaling overhead are proposed for joint processing coordinated (JP) multi-point transmission. The objective is to maximize the weighted sum rate within joint transmission clusters. As the considered weighted sum rate maximization is a nonconvex problem, successive convex approximation techniques, based on weighted mean-squared error minimization, are a...

Smart Grid solutions are being driven by the desire for more efficient energy usage worldwide. Nowadays Smart Grid communications network is a heterogeneous network based on many different standards. This paper describes the suitability of Wi-Fi technology for use in the Smart Grid backhaul.

Today, power line communications (PLC) based WiFi extenders are emerging in the market. By simply plugging an extender to a power outlet, a user can create a second access point which connects to a master AP/router using the power line infrastructure. The underlying belief is that this can enhance the throughput that a user can achieve at certain locations (closer to the extender) and potential...

Transport networks serving as backhaul for rural 3G femtocells have been specified in previous deliverables generated in TUCAN3G. These networks are initially planned based on the expected traffic generated to/from several rural access nodes, and the transport network planning ensures that all links offer a high enough capacity to bear the expected maximum throughput. However, the static situat...

The recent increase in data rates for Free space optics (FSO) transmission technology, means they could be used designing the backhaul/fronthaul 5G and beyond cellular networks. flexibility cost-effectiveness provided by FSO are primary reasons mobile operators to investigate potential of technology as a backhaul/fronthaul. Unfortunately, reliability links is weather dependent, especially if li...
