1. A user equipment (UE), comprising:
a memory interface to store system information in a memory device; and
a processor configured to:
determine, from the system information, that a carrier supports a standalone (SA) operation of a first radio access technology (RAT); and
for the SA operation of the first RAT:
perform a storage list search (SLS), according to SLS search criteria, of recently used frequencies of at least the first RAT;
in response to the SLS search criteria not being satisfied, perform a deviated band search (DBS), according to DBS search criteria, wherein for the first RAT the DBS is limited to configured bands of the carrier; and
in response to the DBS search criteria not being satisfied, skip bands of the first RAT in a remaining band search (RBS).
