Abstract: The present specification provides a method for transmitting uplink data (UL data) requiring a low latency in a wireless communication system. The method performed by a terminal comprises: receiving control information related to a contention-based PUSCH zone from a base station; and transmitting uplink data to the base station on the basis of the received control information. The contention-based PUSCH zone is a resource area where uplink data of the terminal can be transmitted without allocation of a UL grant from the base station. Further, in order to distinguish between kinds of specific procedures performed by the terminal, the control information includes procedure-distinguishing information allocated for each kind of the specific procedures.

Abstract: A method performed by a user equipment (UE) that operates according to a first indicator and a second indicator is provided. When the UE is in a radio resource control (RRC) connected state with a first communication system and is in a state of idle mode with a second communication system, the UE receives a first message including the first indicator and the second indicator from the first communication system. The first indicator instructs the UE to perform association processes with a base station of the second communication system. The second indicator instructs the UE to operate in a power saving mode with the base station of the second communication system. After the UE performs the association processes, the UE switches to an RRC-idle mode state with the first communication system and enters the power saving mode from the idle mode with the second communication system.
