OFDMA femtocell networks are widely recognized as a promising technology for future cellular networks. However, the hybrid utilization of macro/femto networks brings resource management and interference issues. When a femto base station (fBS) is close to a macro BS (mBS), the mBS may generate strong interference to nearby mobile stations (MSs) which are(More)
—Device-to-Device (D2D) communication has become an attractive alternative in bringing popular mobile video contents much closer to the end users. However resulting interference caused by the direct communicating D2D pair demands sufficient resources as well as proper admission control mechanisms for the corresponding mode. To resolve these issues, in this(More)
Cognitive femtocells have an extra feature of utilizing spare spaces of primary users band for the indoor users. To achieve self-configurability in femtocell networks, we design a scheme where cognitive femtocells can follow a decision-making mechanism to organize themselves in different operation modes. We propose an algorithm for mode selection that can(More)
