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.

In particular, a base station transmits, to a terminal, an RNTI mapped to a downlink terminal group or an uplink terminal group including a terminal, and a terminal ID instructing the terminal in the downlink terminal group or the uplink terminal group. The RNTI and the terminal ID are used to set control information, and the control information includes an identification information field instructing whether scheduling information on the terminal exists, a scheduling information field for the terminals in each terminal group, and a first CRC field. The first CRC field is encoded for the scheduling information field for the terminals in each terminal group. The set control information is transmitted to the terminal.

Abstract: Provided are a method and device for transmitting control information in a wireless communication system. In particular, a downlink resource block group including a downlink resource block in a downlink frequency bandwidth is set, and an uplink resource block group including an uplink resource block in an uplink frequency bandwidth is set. If the downlink frequency bandwidth is smaller than the uplink frequency bandwidth, the downlink resource block group is mapped to the uplink resource block group. The ratio of the number of uplink resource blocks to the number of downlink resource blocks is set so that the number of uplink resource block groups and the number of downlink resource block groups become the same. The uplink and downlink resource block groups are mapped according to the ratio. Control information on the mapping is transmitted through the downlink resource block groups.
