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.

Abstract: A method, performed by a user equipment (UE), for prioritizing a secondary cell group (SCG) supported cell in dual connectivity is provided. The method includes detecting whether the SCG supported cell is called for with respect to a service that is triggered at the UE and detecting that a connection of the UE with the SCG supported cell is released in a case. Further, the method includes detecting whether the service that is triggered at the UE has ended and detecting, based on network configured SCG measurements, the SCG supported cell by using one or more unused new radio (NR) antennas of the UE. The method also includes identifying a master cell group supporting the detected SCG supported cell and switching from a master cell not supporting SCG to the identified master cell group supporting the detected SCG supported cell.

Abstract: Methods and apparatuses are provided in which a message is received at a user equipment (UE) from one or more radio access network (RAN) nodes. The UE determines presence of an information element (IE) in the message. The UE determines an interface protocol supported by each of the one or more RAN nodes based on a value indicated in the IE. The UE establishes communication with a first RAN node of the one or more RAN nodes based on a priority associated with the interface protocol of the first RAN node.

Abstract: The disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A method for handling handover by a UE (400) is provided. The method includes determining, by User Equipment (UE), whether a measurement identity (ID) of a first neighboring cell and a measurement ID of a second neighboring cell are same. If the measurement ID of the first neighboring cell and the measurement ID of the second neighboring cell are different, the method includes prioritizing sending of a measurement report of the first neighboring cell over a measurement report of the second neighboring cell to a serving cell. If the measurement ID of the first neighboring cell and the measurement ID of the second neighboring cell are same, the method includes splitting a measurement report for the first neighboring cell and a measurement report of the second neighboring cell and sending the measurement report of the first neighboring cell before the measurement report of the second neighboring cell.

Abstract: A method for managing cell reselection by a user equipment (UE) is provided. The method includes storing, at the UE, a set of allowed frequency bands supported by a first operator. The set of allowed frequency bands are determined based on a first set of frequency bands supported by the first operator, and a second set of frequency bands associated with a second operator and permitted for use by the first operator. The method includes decoding a first system information block (SIB) comprising frequency information and frequency band information associated with corresponding neighbouring cells. The method includes determining one or more relevant neighbouring cells based on the corresponding first SIB and the set of allowed frequency bands, and further, determining, based at least on cell measurements associated with the one or more relevant neighbouring cells, at least one of a neighbouring cell for reselection.
