Mobility Performance Enhancements Based on Radio Link Quality for LTE-Advanced Heterogeneous Networks
Summary :
Heterogeneous networks (HetNets) can provide higher capacity and user throughput than homogeneous networks in Long Term Evolution (LTE)-Advanced systems. However, because of increased interference from neighboring cells and the characteristics of the embedded small cells, handover performance is impacted adversely, especially when the user equipment (UE) moves at medium or high speeds. In this paper, to improve mobility performance, we propose two schemes, i.e., 1) using wideband signal-to-interference noise ratio (SINR) as the handover metric and 2) emergency attaching. The schemes can enhance mobility performance since handovers are performed based on the quality of the radio link. Importantly, the two schemes compliment rather than contradict each other. System-level simulations show that both the individual proposed schemes and the joint schemes can improve mobility performance significantly.
