The fifth generation (5G) system architecture is defined as service-based and the core network functions are described as sets of services accessible through application programming interfaces (API). One of the components of 5G is Multi-access Edge Computing (MEC) which provides the open access to radio network functions through API. Using the mobile edge API third party analytics applications ...

Future radio access networks (RANs) will activate and deactivate base stations (BSs) depending on the activity of users to conserve energy. Reducing the fraction of time a BS is enabled will reduce the energy consumption of the RAN. Using cooperative transmissions from BSs allows to reach user equipment (UE) that is not in range of any single BS. When some BSs cooperate, other BSs can be deacti...

The delay characteristics of small IP packets in cellular data networks is investigated through the analysis of the SR-ARQ mechanism. The delay of the radio link controller is taken as the primary delay in the radio access network and all core networking delays are neglected. Results indicate that the average delay may be a misleading measure of system performance for conversational traffic suc...

This study presents a full-duplex Radio-over-Fiber (RoF) system providing the users' wireless access with a bit rate of 10 Gbps over 40 GHz radio carrier. This system can be used in a centralized radio access network (C-RAN) architecture because we provide a fully analog front haul link between central station and base station. We can consider it as infrastructure between remote radio heads (RR...
