1. A method comprising:
determining whether a user equipment (UE) is capable of simultaneous communication with a source cell and a target cell;
based on determining that the UE is capable of simultaneous communication with the source cell and the target cell, determining one or more first communication capabilities of the UE with the source cell and one or more second communication capabilities of the UE with the target cell;
generating a handover indicator based at least on the one or more first communication capabilities and the one or more second communication capabilities, the handover indicator having one or more fields indicating that the UE is capable of simultaneous communication with the source cell and the target cell;
transmitting the handover indicator to an access node; and
receiving, from the access node based on receipt by the access node of the handover indicator, a command to perform handover,
wherein the one or more fields indicating that the UE is capable of simultaneous communication with the source cell and the target cell comprise
a first field indicating that the UE is capable of simultaneous reception in the source cell and the target cell;
a second field indicating that the UE is capable of simultaneous transmission in the source cell and the target cell;
a third field indicating that the UE is capable of simultaneous transmission in the source cell and reception in the target cell; and
a fourth field indicating that the UE is capable of simultaneous reception in the source cell and transmission in the target cell during the handover.
