1. A method performed by a communication terminal for handling measurements of reference signals from a cell operated by a radio network node in a wireless communication network, the method comprising:
in response to one or more missed measurement samples, adjusting a filter algorithm usable when the reference signals from the cell are not available for measuring by the communication terminal at every designated reference signal occasion, wherein:
the filter algorithm comprises a layer-3 filtering; and
adjusting the filter algorithm is based on one or more previous measurement samples of a previous reference signal from the cell, and further based on respective ages of the one or more previous measurement samples; and
using the adjusted filter algorithm in a measurement procedure.
