- Abstract
- Macrocell base stations are mainly aiming to serve outdoor mobile users thus indoor mobile users may suffer from weak signals because of the outdoor-to-indoor wall penetration loss and indoor obstacles. Recently, in order to improve indoor performance, femtocell networks have been receiving a great deal of attention. However, since the femtocell and macrocell share the same frequency band, co-channel interference (CCI) between them is one of serious problems in femtocell networks. In order to reduce co-channel interference, this paper proposes a novel CCI avoidance scheme using the control channel information based on location information for the downlink of Long Term Evolution (LTE) femtocell networks. Simulation results show that the proposed scheme outperforms other schemes in terms of the outage probability and system throughput.
