Method and apparatus for performing fast data transfer in random access procedure in wireless communication system

摘要

A method for performing fast data transfer by a random access procedure in a wireless communication system is provided. A method performed by a terminal includes a control message including first information indicating whether selection for a second TBS smaller than the first TBS for message 3 is allowed and second information for the first TBS. Receiving a request for EDT from the base station using a message 1, receiving a message 2 including a UL grant for message 3 from the base station, a control message and a message based on the UL grant. Determining the number of repetitions for 3 and forwarding the message 3 to the base station for the number of repetitions. Accordingly, there is an effect that the battery consumption of the terminal can be reduced. [Selection diagram] FIG.
