1. A device comprising:
a receiver comprising a plurality of antennas configured to receive a reference signal;
a controller configured to
switch between multiple receive configurations of the plurality of antennas within a reception period of the reference signal, and
skip, based on a signal quality value of a previously received reference signal, selected one or more receive configurations of the multiple receive configurations when switching between the multiple receive configurations; and
a signal quality determining circuit configured to determine a signal quality value of the reference signal for each receive configuration of the multiple receive configurations that is not skipped.
