Abstract: In an embodiment, a method, implemented in a User Equipment (UE) operating in Evolved Universal Terrestrial Radio Access Network (E-UTRAN) New Radio-Dual Connectivity (EN-DC), of adding a New Radio (NR) Secondary Node (SN) in EN-DC is disclosed. The method includes receiving, in response to a measurement report sent by the UE, configuration data associated with an NR cell. The method includes, ascertaining whether the configuration data comprises a pre-determined parameter indicative of a frequency-shift for dynamic spectrum sharing for an uplink. The method includes performing one of an addition of an NR SN corresponding to the NR cell or a transmission of a failure notification message to the MN, based upon determining that the pre-determined parameter indicative of the frequency-shift criteria for dynamic spectrum sharing for the uplink is absent or present in the configuration data.
