Abstract: Systems, methods, apparatuses, and computer program products for uplink switch to source cell in dual active protocol stack handover. A method may include receiving a handover command. The method may also include identifying a maximum permissible exposure event at a user equipment before or after reception of the handover command. The method may further include delaying an uplink switch to a target network element from a source network element due to the maximum permissible exposure event, or switching back to the source network element. According to certain example embodiments, delaying the uplink switch may include setting an event trigger to switch to the target network element. In addition, the method may include informing the target network element about the maximum permissible exposure event, and about the delay in the uplink switch.
