1. A method performed by a User Equipment (UE) for data transmission, the method comprising:
transmitting a radio resource control (RRC) message to a base station for requesting an RRC state transition, the RRC message transmitted on a first uplink (UL) resource of a configured grant (CG) configuration;
transmitting first uplink data to the base station on a second UL resource of the CG configuration;
starting a timer upon transmitting the first uplink data on the second UL resource of the CG configuration;
monitoring a physical downlink control channel (PDCCH) for a response from the base station while the timer is running;
stopping the timer in response to at least one stop condition being satisfied; and
restarting the timer in response to at least one restart condition being satisfied,
wherein:
the at least one stop condition comprises receiving the response, and
the at least one restart condition comprises retransmitting the first uplink data on a physical uplink shared channel (PUSCH) scheduled by the PDCCH or transmitting second uplink data on a third UL resource of the CG configuration.
