Abstract

A heterogeneous network is disclosed having macrocells and picocells with co-channel operation for both low-mobility and high-mobility users. The co-channel operation occurs over both coordinated and uncoordinated resources. During normal operation without any handover conditions, the high-mobility user communicates with a macrocell base station in both the coordinated and uncoordinated resources. But if a handover condition to a low-power node (a picocell) arises, the high-mobility user is rescheduled to communicate only in the coordinated resources without allowing a picocell handover despite the handover condition to prevent handover failures (HFs) and to minimize ping-pongs. On the other hand, low-mobility users are allowed to make handover to picocells.
