Method and apparatus for reference signals in a measurement window

An apparatus comprising:

• a transceiver that
• receives information of at least one measurement reference signal resource and measurement timing configuration, and
• receives downlink signals in a first measurement window;
• and
• a controller coupled to the transceiver, where the controller
• attempts to detect at least one measurement reference signal on the at least one measurement reference signal resource from the downlink signals received in the first measurement window,
• performs measurements on a first set of measurement reference signals from the at least one measurement reference signal, where the first set of measurement reference signals comprises at least one successfully detected measurement reference signal from the at least one measurement reference signal,
• identifies a second set of measurement reference signals from the at least one measurement reference signal, where the second set of measurement reference signals was not detected in the first measurement window, and
• attempts to detect at least the second set of measurement reference signals in a second measurement window, where the second measurement window starts no earlier than an end of the first measurement window.
