In this paper, the unnecessary handover avoidance scheme is discussed in Long Term Evolution-Advanced (LTE-A) small cells. Specifically, a handover is considered as unnecessary one if the active time in the target cell (i.e., duration where the user equipment can perform data communication) is not larger than a pre-defined threshold, where the active time is predicted before the handover through the...
Efficient radio resource allocation is essential to provide quality of service (QoS) for wireless networks. In this paper, a cross-layer resource allocation scheme is presented with the objective of maximizing system throughput, while providing guaranteed-QoS for users. With the assumption of a finite queue for arrival packets, the proposed scheme dynamically allocates radio resources based on user's...
