In this paper, we consider a joint power control and resource allocation scheme for co-channel deployed femtocells in macrocell networks. The strong interference in the downlink from the femtocells should be well controlled to satisfy the quality of service (QoS) requirement of both macrocell users and femtocell users. We provide both centralized and distributed schemes to solve the formulated optimization...
Due to high data rate requirement for indoor radio coverage, femtocells have been proposed as a potential good solution in recent years. Under this configuration, a main design objective is to coordinate the mutual interference between macro and femto cells. In this paper, the flexible assignment of downlink resource in a hierarchical cell structure is investigated. A dynamic frequency assignment...
