In this work, we consider Quality of Service (QoS) guarantee for Device to Device (D2D) users co-existing with a cellular system where the D2D communication links are sharing radio spectrum resources with macrocell users in the downlink. Despite the lofty advantages associated with D2D communications, one major concern is the resulting interference from the D2D users, which should not infringe on...
This study takes advantage of the ability of Physical-Layer Network Coding (PNC) to embrace electromagnetic interference, improve spectral efficiency and achieve throughput optimality in a femtocell operated as a relay. Specifically, we make a case for a femtocell operating as a relay and utilizing PNC to eliminate the interference that exists between macrocells user equipments (MUEs) and femtocells...
