Performing measurements for a handover procedure in a non-terrestrial network
A method for a user equipment (UE) connected to a serving cell associated with a first satellite is provided. The method receives a measurement configuration including a plurality of synchronization signal block (SSB) measurement timing configurations (SMTCs). Each SMTC may have at least one offset value and a first SMTC in the plurality of SMTCs has a first offset value that is different from a second offset value of a second SMTC of the plurality of SMTCs. The method further receives a signal to perform a measurement procedure for a second cell associated with a second satellite and performs the measurement procedure based on the received plurality of SMTCs.
