Abstract
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Provided is a method performed by a terminal in a wireless communication system that includes receiving a radio resource control (RRC) message including information associated with a deactivation of a secondary cell group (SCG), and resetting a medium access control (MAC) of the SCG based on the RRC message, with a timing alignment timer (TAT) associated with the SCG not being stopped for resetting the MAC of the SCG.
Claims12
A method performed by a terminal in a wireless communication system, the method comprising:
- receiving a radio resource control (RRC) message including first information on a deactivation of a secondary cell group (SCG) and second information on a configuration of beam failure detection and radio link monitoring;
- resetting a medium access control (MAC) of the SCG based on the RRC message, and
- stopping all timers, except a beam failure detection timer associated with a primary SCG cell (PSCell) and a timing alignment timer (TAT) based on the deactivation of the SCG and the configuration of beam failure detection and radio link monitoring.
A terminal in a wireless communication system, the terminal comprising:
- a transceiver;
- and
- at least one processor coupled to the transceiver and configured to:
- receive a radio resource control (RRC) message including first information on a deactivation of a secondary cell group (SCG) and second information on a configuration of beam failure detection and radio link monitoring,
- reset a medium access control (MAC) of the SCG based on the RRC message, and
- stop all timers, except a beam failure detection timer associated with a primary SCG cell (PSCell) and a timing alignment timer (TAT) based on the deactivation of the SCG and the configuration of beam failure detection and radio link monitoring.
