This work studies femtocell resource allocation in shared spectrum heterogeneous networks. We propose an enhanced shadow chasing method for femtocell resource allocation to achieve interference mitigation in heterogeneous networks serving both Macrocell User Equipments (MUEs) and Home User Equipments (HUEs). Shadow chasing home eNB (HeNB) uses Downlink Control Information (DCI) together with over-heard...
For the orthogonal frequency division multiple access (OFDMA) networks that adopt relaying technology, this paper suggests a novel two hop scheduling scheme that adjusts the transmission time of each hop. Since relays cannot forward data until they receive data from base station, the data transmission consists of two hops for base station to relay and relay to mobile station. In this case, wireless...
