Abstract
Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for a user equipment (UE) having dual connectivity. The UE can communicate with a first primary base station in a first primary cell (PCell) and a second primary base station in a second PCell. The UE has dual connectivity in the second PCell using a first wireless carrier to communicate with the second primary base station and a second wireless carrier to communicate with a secondary base station in a primary secondary cell (PSCell). The UE receives a message from the first primary base station to perform a handover procedure. The UE performs the handover procedure according to the received message, and further perform an addition procedure for the secondary base station in parallel with the handover procedure. A start time of the addition procedure can be before an end time of the handover procedure.
