Abstract: Various communication systems may benefit from improved handover techniques. For example, a communication system may allow for an autonomous user equipment handover operation in a licensed or unlicensed spectrum. A method may include receiving a measurement condition at a user equipment. The measurement condition may include a maximum duration of time for sending a message to a base station of a source cell.

In addition, the method may include commencing the autonomous handover after the duration of time of the measurement condition has expired or upon successful transmission of the message to the base station of the source cell.
