Abstract
A method performed by a terminal in a wireless communication system is provided. The method includes in case that a random access procedure for small data transmission (SDT) in a radio resource control (RRC) inactive state is initiated, transmitting, to a base station, a RRC message including a parameter associated with a size of uplink data, receiving, from the base station, a response message including information associated with transmission resource for the uplink data, and transmitting, to the base station, the uplink data based on the transmission resource.

A method performed by a terminal in a wireless communication system, the method comprising:
- transmitting, to a base station, a radio resource control (RRC) message comprising a parameter associated with a size of uplink data in case that a random access procedure for small data transmission (SDT) in a RRC inactive state is initiated;
- receiving, from the base station, a response message comprising information associated with a transmission resource for the uplink data;
- and
- transmitting, to the base station, the uplink data based on the transmission resource.
A method performed by a base station in a wireless communication system, the method comprising:
- receiving, from a terminal, a radio resource control (RRC) message comprising a parameter associated with a size of uplink data in case that a random access procedure for small data transmission (SDT) in a RRC inactive state is initiated;
- transmitting, to the terminal, a response message comprising information associated with a transmission resource for the uplink data;
- and
- receiving, from the terminal, the uplink data based on the transmission resource.
A terminal in a wireless communication system, the terminal comprising:
- a transceiver;
- and
- at least one processor configured to:
- transmit, to a base station via the transceiver, a radio resource control (RRC) message comprising a parameter associated with a size of uplink data in case that a random access procedure for small data transmission (SDT) in a RRC inactive state is initiated,
- receive, from the base station via the transceiver, a response message comprising information associated with a transmission resource for the uplink data, and
- transmit, to the base station via the transceiver, the uplink data based on the transmission resource.
A method performed by a terminal in a wireless communication system, the method comprising:
- transmitting, to a base station, a random access preamble in case that a random access procedure for small data transmission (SDT) in a radio resource control (RRC) inactive state is initiated;
- receiving, from the base station, information indicating that the terminal is to perform non-SDT;
- identifying whether to end an ongoing random access procedure for the SDT based on the information;
- and
- performing the non-SDT based on the identification.
A method performed by a base station in a wireless communication system, the method comprising:

- transmitting, to the terminal, information indicating that the terminal is to perform non-SDT,
- wherein whether to end an ongoing random access procedure for the SDT is identified based on the information;
- and
- performing the non-SDT based on the identification.
