Measurement gaps in LTE for B1NR

How to configure measurement gaps in LTE for B1NR measurement so that UE is able to measure the NR Cell on given ssbfrequency, ssbduration and ssbperiodicity?

enodeB will set: time-synchronization with gnb, position of external 5G cell’s SSB in time-domain, measurement gaps with periodicity & offset for eg: 6ms GAP every 40ms, SSB transmit within 5ms must fill into 6ms GAP
