A communication device can operate in a wireless communication network. The communication device can detect a measurement report triggering event based on a measurement of a first reference signal received by the communication device and based on a measurement of a second reference signal received by the communication device. The first and second reference signals can be different. The communication device can further transmit a measurement report to the wireless communication network responsive to detecting the measurement report triggering event. The measurement report includes at least one of the measurement of the first reference signal and/or the measurement of the second reference signal.
