In emerging small cell wireless, each Femtocell Access Point (FAP) can either service its home subscribers exclusively (i.e., closed access) or open its access to accommodate a number of macrocell users so as to reduce cross-tier interference. In this paper, the authors propose a game-theoretic framework that enables the FAPs to strategically decide on their uplink access policy. They formulate a non-cooperative game in which the FAPs are the players that want to strategically decide on whether to use a closed or an open access policy in order to maximize the performance of their registered users.
