Abstract
Provided is a method performed by a user equipment (UE) in a wireless communication system supporting Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network (E-UTRAN) New Radio (NR)-Dual Connectivity (ENDC). The method includes: receiving system information including information on an NR band list supported in the ENDC; identifying, based on the system information, NR bands supported at LTE frequencies of Long Term Evolution (LTE) bands in a most recently used (MRU) LTE frequency list of the UE; prioritizing the LTE frequencies in the MRU LTE frequency list, based on the supported NR bands and an ENDC capability of the UE; and performing a cell selection based on the prioritized MRU LTE frequency list.
