1. A method performed by a wireless device, the method comprising:
receiving a frequency domain monitoring locations configuration from a network node, the frequency domain monitoring locations configuration indicating which set(s) of resource blocks (RBs), out of multiple RBs, shall be monitored for control channel candidates, wherein each indicated set of RBs corresponds to physical resource blocks (PRBs) of a respective frequency domain monitoring occasion that does not overlap any guard PRBs, wherein each frequency domain monitoring occasion is determined by a frequency translation of control channel elements (CCEs) defined in an associated control resource set (CORESET) through a frequency offset; and
monitoring for one or more control channel candidates within the frequency domain monitoring occasion(s) based on the received frequency domain monitoring locations configuration.
