摘要

Home Evolved Node B (HeNB), which is the base-station of femtocell, is a popular research topic in the future Long Term Evolution (LTE) networks. It can serve many indoor users and improve the spectrum utility. However, the large amount of HeNBs also causes heavy interference. In this paper, we propose a novel scheme called QoS-aware cooperative power control and resource allocation (QCPR) to maintain the QoS of user constraints and reduce the interference in femtocell networks by considering each HeNBs troubling and servicing aspects. QCPR is composed by two operation stages. First, the chief troubling HeNBs transmission power is adjusted according to its interference and service factors. Then, a probabilistic-based resource allocation algorithm is executed to arrange each HeNBs transmission time/frequency to further enhance the overall spectrum reuse. The simulation results illustrate that, comparing to other existing power control and resource allocation schemes, QCPR effectively avoids the interferences between neighbor HeNBs, and thus better satisfies QoS connections and improves aggregate throughput of the femtocell networks.
