초록
The femtocell overlaid cellular network (FOCN) has been used to enhancethe capacity of existing cellular systems. To obtain the desired system performance,both cross-tier interference and co-tier interference in an FOCN need to be managed. This paper proposes an interference management scheme that adaptively constructs afemtocell cluster, which is a group of femtocell base stations that share the samefrequency band. The performance evaluation shows that the proposed scheme canenhance the performance of the macrocell-tier and maintain a greater signal tointerference-plus-noise ratio than the outage level can for about 99% of femtocell users.
