    摘要: A method for handling cell selection in a wireless communication system is provided. The method includes detecting, by a UE, a plurality of neighboring LTE cells having a signal strength better than a serving LTE cell. Further, the method includes acquiring, by the UE, a SIB 1 type message from the detected plurality of neighboring LTE cells. Further, the method includes detecting, by the UE, a neighboring LTE cell from the detected plurality of neighboring cells to have a 5GC based on the acquired SIB 1 type message. Further, the method includes prioritizing selection of the neighboring LTE cell having the 5GC over the detected plurality of neighboring cells.

    摘要: 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.

    摘要: Method handling uplink (UL) bearer split configuration in multi-connectivity system includes identifying first UL data of a packet data convergence protocol (PDCP) layer, transmitting first data of first UL data to a primary radio link control (RLC) entity for a first time period, and transmitting second data of the first UL data to a secondary RLC entity for a second time period, identifying at least one first network parameter of a first UL path associated with the primary RLC entity for the first time period, and identifying at least one second network parameter of a second UL path associated with the secondary RLC entity for the second time period, determining a split factor for splitting second UL data of the PDCP layer between the primary RLC entity and the secondary RLC entity based on the at least one first network parameter and the at least one second network parameter, and transmitting the second UL data to the primary and secondary RLC entities for a third time period based on the split factor.

    摘要: Accordingly the embodiments herein provide a method for indication of change in multi-radio access technology (RAT) dual connectivity (MR-DC) capability of a user equipment (UE). The method includes detecting the change in the MR-DC capability of the UE, and identifying an operation mode of the UE, the operation mode being one of an idle mode and a connected mode. The method further comprises in response to the operation mode being the idle mode, detecting an event, checking a validity of the change in the MR-DC capability of the UE after detecting the event, and indicating the change in the MR-DC capability of the UE to the first network node based on a result of the check. Further the method comprises in response to the operation mode being the connected mode, identifying that UE-assistance information is configured by the first network node, and indicating the change in the MR-DC capability of the UE to the first network node based on the UE-assistance information.
