The macro-femto overlaid LTE-Advanced networks have been drawing many attentions from mobile operators with their capability of extending coverages and supporting higher data rates. Effective and efficient resource allocation schemes must be preceded in order to deploy this overlaid cellular network successfully. This paper proposes the adaptive resource management scheme which categorizes the entire time-frequency resource blocks of the overlaid cellular network into the dedicated and the

Moreover, it enables to share loads evenly in the overlaid cellular network by performing cross-tier handovers from the macrocell to the femtocell so as to maximize the total packet throughput to a certain degree. We used a simulation to evaluate the effectiveness of our scheme with the performance measure of the outage probability and total packet throughput.
