Abstract: 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.

Abstract: Embodiments herein disclose a method for handling RLF in a MRDC system comprising a UE connected to a Master Node and at least one Secondary Node (SN). The method includes detecting, by the UE, a radio link failure (RLF) with the master node. Further, the method includes determining, by the UE, whether a Secondary Node termination condition is met. Further, the method includes performing one of: maintaining, by the UE, a connection with the at least one secondary node till the SN termination condition is met in response to determining that the SN termination condition is not met, and releasing, by the UE, the connection with the at least one secondary node in response to determining that the SN termination condition is met.
