1. A method by a terminal, the method comprising:
receiving, by the terminal from a base station, a RRCReconfiguration, wherein the RRCReconfiguration comprises:
a measurement report configuration;
a first Synchronization Signal/Physical Broadcast Channel block Measurement Timing Configuration (first SMTC); and
a second SMTC, and
wherein the first SMTC comprises:
a joint parameter for offset and periodicity; and
a duration parameter:
wherein the second SMTC comprises:
a list of physical cell identifiers; and
an offset parameter:
wherein the measurement report configuration comprises:
a first reference position;
a second reference position;
a first threshold;
a second threshold;
a hysteresis; and
a reference signal type;
setting up, by the terminal:
a Synchronization Signal/Physical Broadcast Channel (SS/PBCH) block measurement timing configuration based on the first SMTC; and
an additional SS/PBCH block measurement timing configuration based on the first SMTC and the second SMTC;
performing, by the terminal, a measurement based on the SS/PBCH block measurement timing and the additional SS/PBCH block measurement timing configuration;
initiating, by the terminal, a measurement report procedure based on a first comparison and a second comparison, wherein the first comparison is a comparison between:
the first threshold; and
a value obtained by subtracting the hysteresis from a first distance,
wherein the second comparison is a comparison between:
the second threshold; and
a value obtained by adding the hysteresis to a second distance,
wherein the first distance is a distance between the terminal and the first reference position, and
wherein the second distance is a distance between the terminal and the second reference position; and
transmitting, by the terminal to the base station, a MeasurementReport, wherein the MeasurementReport comprises a Reference Signal Received Power (RSRP) and a Reference Signal Received Quality (RSRQ) measured according to the reference signal type, and
wherein:
the SS/PBCH block measurement timing configuration is determined based on first offset and a first periodicity and a first duration;
the additional SS/PBCH block measurement timing configuration is determined based on second offset and the first periodicity and the first duration:
the first offset and the first periodicity are determined based on the joint parameter in the first SMTC:
the first duration is determined based on the duration parameter in the first SMTC: and
the second offset is determined based on the offset parameter in the second SMTC.
