The UE supports Frequency Division Duplex (FDD) and Time Division Duplex (TDD). The UE capability transmitting method includes receiving a message requesting UE capability information from an evolved Node B (eNB), generating first capability information and second capability information according to the UE capability information requesting message, and transmitting UE capability information including the first and second capability information to the eNB. The first capability information comprises FDD capability information applicable to an FDD mode or TDD capability information applicable to a TDD mode. The second capability information comprises capability information applicable to both the FDD mode and the TDD mode. The system and method can allow a dual mode UE to efficiently report its capability information.

Abstract: Embodiments herein disclose a method for executing conditional handover by a UE in a wireless communication network. The method may include receiving an RRC reconfiguration message from a source cell of the wireless communication network. The RRC reconfiguration message may include a handover configuration and determining whether a CHO configuration may be provided in the handover configuration. Further, the method may include performing one of: continuing an RLM timer and an RLM procedure on the source cell, in response to determining that the CHO configuration is provided in the handover configuration; and stopping the RLM timer and suspending the radio link monitoring procedure on the source cell, in response to determining that the CHO configuration is not provided in the handover configuration. The method may then include executing the CHO from the source cell to a candidate target cell in the wireless communication network based on the CHO configuration.
