1. A processor, comprising:
memory storing instructions that, when executed, cause a user equipment (UE) to:
receive one or more synchronization signal blocks (SSBs) on one or more receive beams as part of a measurement procedure with listen before talk (LBT);
determine one or more synchronization signal block (SSB) based radio resource measurement (RRM) timing configuration windows (SMTCs) are not available in a UE measurement period;
select, in response to determining the one or more SMTCs are not available in the UE measurement period, a measurement period based on a sum of a first term and a second term, wherein the first term is a baseline measurement period and the second term is a product of a plurality of values including a carrier-specific scaling factor value, a SMTC periodicity value, a UE receive (Rx) beam sweeping factor, and a value based on the one or more SMTCs not being available in a UE measurement period; and
perform measurements using the selected measurement period.
