    Abstract: A system and method provide a security aspect for a UE in dual connectivity mode of operation in wireless communication networks. The system and method provide secure simultaneous transmission and reception in a secure manner between a User Equipment (UE) and one or more eNodeBs (eNBs) configured in an inter-eNB carrier aggregation scenario. The system establishes of a security context between the UE and the Secondary eNB (SeNB) using the RRC signaling between the UE and the Master eNB (MeNB), when a plurality of SCells within SeNB are added simultaneously. The system also detects the intruder in the user data radio bearers, while a UE is operating in dual connectivity mode of operation.

    Abstract: A method and system to handle behavior of a carrier aggregation capable User Equipment (UE) that does not support simultaneous reception and transmission in overlapped Downlink (DL)-Uplink (UL) sub frames during inter-band Carrier Aggregation (CA) for cell specific TDD configuration is disclosed. The method specifies whether the UE is allowed or not allowed to monitor the PDCCH sub frames during overlap of DL-UL sub frames by signaling the UE with a resultant TDD configuration that is applicable to component carriers of the PCell and one or more SCells. The method also addresses handling of the DRX timers by defining the active time for common DRX operation by the UE for all component carriers. The method enhances the 3GPP specification to enable UE to better handle reception and transmission during overlap of DL-UL sub frames in cell specific TDD configuration during inter-band CA.

    Abstract: Embodiments herein provide a method for handling a user plane by a UE configured for dual connectivity operation. The method includes receiving a RRC reconfiguration message including one or more Layer 2 indications and a Layer 2 configuration corresponding to one or more radio bearers from one of a MN and a SN involved in a dual connectivity operation of the UE. Further, the method includes performing, by the UE, one of: reestablishing of a RLC entity and a data recovery procedure for a PDCP entity corresponding to the radio bearer based on the one or more Layer 2 indications and the Layer 2 configuration received in the RRC reconfiguration message, and reestablishing of a RLC entity and reestablishing of a PDCP entity corresponding to the radio bearer based on the one or more Layer 2 indications and the Layer 2 configuration received in the RRC reconfiguration message.

    Abstract: The present 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 random access procedure in wireless communication system is provided. The method includes determining, by a user equipment (UE), that the UE is in one of an idle mode or an inactive mode, acquiring, by the UE, a system information block (SIB) Type1 (SIB1) message from a cell, determining, by the UE, whether the UE supports a frequency band criterion, a spectrum emission criterion, and a bandwidth part criterion based contents of the acquired SIB1 message, and performing, by the UE, one of camping on the cell in response to determining that the UE supports at least one of the frequency band criterion, the spectrum emission criterion, or the bandwidth part criterion, or barring the cell in response to determining that the UE does not support both the frequency band criterion, the spectrum emission criterion, or the bandwidth part criterion.
