In an embodiment, the method includes detecting a User Equipment (UE) handover trigger based on an aggregate throughput for each Data Radio Bearers (DRBs) in each CoMP link between the UE and each Neighboring Base Stations (NBS) in a set of NBSs, the UE being in communication with a Serving Base Station (SBS) and each NBS in the set of NBSs through a set of active CoMP links; ranking each NBS based on handover potential of each NBS in the set of NBSs; and selecting a target NBS from the set of NBSs for UE handover based on the ranking and UE support capability information associated with each NBS, wherein a subset of the set of active CoMP links is migrated to the target NBS during the UE handover. ## Claims ### Claim 1 A method of Coordinated Multipoint (CoMP) handover in a wireless communication network, the method comprising: detecting a User Equipment (UE) handover trigger based on an aggregate throughput for each Data Radio Bearers (DRBs) in each CoMP link between the UE and each Neighboring Base Stations (NBS) in a set of NBSs, the UE being in communication with a Serving Base Station (SBS) and each NBS in the set of NBSs through a set of active CoMP links;
