1. A method, comprising:
receiving, by a user equipment, at least one first indication indicating when to apply at least one offset synchronization signal block measurement time (SMTC) configuration and at least one measurement gap window based on at least one round trip time (RTT) change, wherein the at least one RTT change is transmitted to at least one core network or controlling unit configured to notify at least one neighbor network entity with at least one next generation (NG) interface;
receiving, by the user equipment, at least one physical cell identity and the at least one RTT change;
updating measurement gap configurations for intra-frequency and inter-frequency measurements based on capabilities of the user equipment;
broadcasting messages indicating offset changes, wherein RTT change messages are configured to adjust both SMTC and measurement gap (MG);
adjusting, by the user equipment, the at least one SMTC at at least one time, wherein the at least one SMTC is adjusted by decreasing SMTC periodicity and increasing the at least one measurement gap window, wherein when in idle mode the user equipment preserves an outdated SMTC configuration until a new system information block 2 (SIB2) or system information block 4 (SIB4) is transmitted, wherein changes to the outdated SMTC configuration applies to intra-frequency measurements and/or inter-frequency measurements; and
adjusting, by the user equipment, at least one measurement gap configuration at the at least one time.
