Abstract: Provided is a method and device for receiving a signal in a wireless communication system to which a multiple-transmission technique is applied. A proposed wireless communication system proposes a method for maximizing packet transmission within a target time in multiple paths. Specifically, a terminal receives, from a first base station, multiple-transmission activation information and control information for transmission of a transmission block. The terminal decodes the multiple-transmission activation information and the control information, and receives the transmission block from the first base station and a second base station. At this time, the multiple-transmission activation information includes a multiple-transmission activation indicator indicating that the first base station and the second base station can transmit the transmission block until a preconfigured time.

Abstract: Provided are a method and device for transmitting uplink data in a wireless communication. More specifically, a user equipment (UE) receives, from a first base station (BS), cell group information indicating that the first BS and a second BS are included in the same cell group. The UE receives, from the first BS, a first reference signal and assignment information regarding a first semi-persistent scheduling (SPS) resource. The UE transmits, to the second BS, a first uplink signal on the basis of the first SPS resource and the first reference signal.

Abstract: Provided are a method and an apparatus for transmitting uplink data in a wireless communication system. Specifically, a first terminal transmits a random access preamble for requesting a connectionless transmission. The first terminal receives a random access response comprising scheduling information of the uplink data. The first terminal transmits uplink data and a reference signal from a first resource configured on the basis of scheduling information of the uplink data and information indicating the CP length of the reference signal. The CP length of the reference signal can be configured to be identical to the CP length of the random access preamble. The first resource can correspond to a resource utilized by both the first terminal and second terminal.
