A Method and Apparatus for discontinuous reception and discontinuous transmission are provided. The method includes receiving a radio resource control (RRC) reconfiguration message, receiving a specific downlink control information, activating cell discontinuous transmission (DTX) for a specific serving cell based on the specific downlink control information, performing physical downlink control channel (PDCCH) monitoring for the specific serving cell based on whether a cell-dtx-timer of the specific serving cell is running, triggering a Scheduling Request (SR) for beam failure recovery, transmitting the SR, performing PDCCH monitoring for the specific serving cell regardless of whether the cell-dtx-timer of the specific serving cell is running, transmitting a MAC CE comprising beam failure related information, and canceling the SR triggered for beam failure recovery.

A method and apparatus for enhanced discontinuous reception is provided. Method for discontinuous reception includes receiving a downlink RRC message from the base station, determining a method for determining the first timer start subframe based on the first DRX parameter and starting the first timer based on the determination. The terminal uses the first method if the first DRX parameter is absent. The terminal uses the second method if the first DRX parameter is present.

A method and apparatus for enhanced discontinuous reception is provided. Method for discontinuous reception includes receiving a downlink RRC message from the base station, determining a first subframe to start the first timer based on first counter and second counter and starting the first timer based on the determination. The second counter is set to a specific value if a specific DRX parameter is present.

A Method and Apparatus for multi-SIM operation during handover is provided. The method includes receiving from a base station a first RRCReconfiguration, transmitting to the base station a UEAssistanceInformation, starting the first timer after initiating transmission of UEAssistanceInformation, receiving from the base station a second RRCReconfiguration and starting the second timer before initiating random access procedure. The first RRCReconfiguration includes a configuration information related to terminal state transition, the configuration information related to terminal state transition includes a information for a first timer, the first timer is a timer related to terminal state transition. The UEAssistanceInformation includes a information related to terminal's state. The second RRCReconfiguration includes a ReconfigurationWithSync, the ReconfigurationWithSync includes a information for a second timer related to handover. The first timers stops if the second timer expires while the first timer is running. The second timers stops if the first timer expires while the second timer is running.
