Abstract: When the femtocell performs power control in order to reduce the interference level, this may degrade the SNR at the femto-user side if the transmitted power is reduced to large amount. Thus power control is not efficient and other methods such as spectrum splitting among the femtocells is not efficient too and waste recourses. Femtocells must have a new mechanism so that to manage interference and reduce the reliance on power reduction technique. Here we present a solution in time/frequency domain in order to avoid interference in co-channel deployment between femtocell and macrocell through efficient PCI planning and macro-user tracing. The results of the presented scheme show improvements in the downlink SNR and throughput due to maintaining the signal quality at the macro-user side.
