    Abstract: A method for transmitting and receiving a radio signal in a wireless communication system and a device therefor are disclosed. A method for receiving, by a base station, a sounding reference signal (SRS) in the wireless communication system includes transmitting, to a user equipment (UE), configuration information for transmission of the SRS; and receiving, from the UE, the SRS transmitted based on the configuration information. The configuration information includes group hopping information and sequence hopping information for sequence hopping of the SRS. A sequence length of the SRS is based on a product of a number of candidates of the group hopping information and a number of candidates of the sequence hopping information. The number of candidates of the group hopping information and the number of candidates of the sequence hopping information are configured based on a number of neighboring cells of the base station.

    Abstract: A method for receiving downlink data by the terminal in a wireless communication system, includes receiving, from a base station, downlink control information for scheduling a short physical downlink shared channel (sPDSCH) on a short physical downlink control channel (sPDCCH), and receiving, from the base station, downlink data on the sPDSCH based on the downlink control information. Here, the sPDCCH and the sPDSCH are based on a first transmission time interval (TTI)-based radio frame structure, wherein the first TTI-based radio frame structure is shorter in time than a second TTI-based radio frame structure related to (i) a physical downlink shared channel (PDSCH) and (ii) a physical downlink control channel (PDCCH). Further, a number of resource element groups (REGs) consisting of a control channel element (CCE) related to the sPDCCH is smaller than a number of resource element groups (REGs) composed of a CCE related to the PDCCH.

    Abstract: A disclosure of the present specification provides a method for determining transmission power of an uplink channel. The method may comprise the steps of: selecting the maximum transmission power from among transmission power of multiple uplink channels transmitted to a specific serving cell in a first subframe; and when a first uplink channel has transmission power lower than the maximum transmission power and the transmission power is smaller than the difference between the maximum transmission power and a first threshold, determining boosting of the transmission power of the first uplink channel. Here, the multiple uplink channels may comprise one or more of an uplink data channel, an uplink control channel, and an uplink reference signal.
