1. A method, performed by a user equipment (UE), for merging measurement objects (MOs) in a New Radio (NR) system including NR unlicensed (NR-U) carriers configured to provide E-UTRA-NR Dual Connectivity (EN-DC) between a licensed band LTE Primary Cell (PCell) and an NR-U Primary Secondary Cell (PSCell), the method comprising:
determining whether an E-UTRA PCell and an NR PSCell configure a same NR carrier frequency layer with clear channel assessment (CCA) to be monitored by the UE in synchronous intra-band EN-DC, wherein the NR PSCell is an NR-U PSCell with CCA and the E-UTRA PCell is a licensed band LTE PCell; and
merging MOs for the same NR carrier frequency layer configured by the NR-U PSCell with CCA and the licensed band LTE PCell by:
counting the same NR carrier frequency layer once to a total number of effective carrier frequency layers by checking that system frame numbers and slot boundaries are aligned and in response to the same NR carrier frequency layer having no differences in RSSI measurement resources, deriveSSB-IndexFromCell indications, SMTC configurations, Q values, and RSSI Measurement Timing Configuration (RMTC) configurations,
wherein the Q values indicate the Quasi-Colocation (QCL) relationship between Synchronization Signal Block (SSB) positions on a frequency indicated by ssbFrequency;
wherein for the MOs of the same NR carrier frequency layer configured by the NR-U PSCell with CCA and the licensed band LTE PCell to be merged, the RMTC and the Q values must be the same.
