Abstract: The present disclosure provides a method for transmitting and receiving a sounding reference signal (SRS) in a wireless communication system and a device therefor. Specifically, a method for transmitting, by a terminal, an SRS in a wireless communication system may comprise the steps of: receiving configuration information for transmission of the SRS from a base station; and transmitting the SRS to the base station by using one or more SRS resources for transmission of the SRS, the configuration information including the one or more SRS resources and information relating to the usage of the one or more SRS resources, wherein a guard period relating to the one or more SRS resources is configured, and when the transmissions of the guard period and a particular uplink channel configured for the terminal overlap each other, the priority between the guard period and the particular uplink channel is configured to be the same as that between the SRS and the particular uplink channel.

Abstract: The present disclosure provides a method for reporting CSI in a wireless communication system. In the present disclosure, a method for reporting channel state information (CSI) in a wireless communication system, which is performed by a UE includes: receiving, from an eNB, downlink control information (DCI) indicating activation of semi-persistent (SP) CSI reporting, in which the downlink control information is scrambled with a specific RNTI distinguished from a Cell-Radio Network Temporary Identity (C-RNTI); and reporting, to the eNB, the semi-persistent CSI through a physical uplink shared channel (PUSCH) based on the received downlink control information.

Abstract: A method is provided for receiving a downlink signal through an Enhanced Physical Downlink Control Channel (EPDCCH) in a wireless communication system by a user equipment (UE). The UE receives a parameter indicating a quasi co-location behavior type is. The UE further receives a demodulation reference signal (DMRS) associated with the EPDCCH. The UE attempts to decode the EPDCCH based on the DMRS. If a transmission mode configured in the UE is a transmission mode 10, the UE assumes that antenna ports of the DMRS are quasi co-located with antenna ports of a reference signal determined by the parameter.

Abstract: Provided are a method for reporting a power headroom and an apparatus using the same. The apparatus computes and reports a power headroom for a physical uplink shared channel (PUSCH) that is transmitted in a first transmission period of a first band having a first subcarrier interval. The power headroom is computed on the basis of at least one second transmission interval of a second band having a second subcarrier interval which overlaps with the first transmission interval.

Abstract: A method for receiving a feedback signal of a base station in a wireless communication system comprises the steps of: transmitting a data packet to a terminal; monitoring, during a preset monitoring interval, a first feedback signal representing whether the data packet has been successfully received or not; determining whether the first feedback signal monitored during the preset monitoring interval is an ACK signal or a NACK signal; and retransmitting the data packet to the terminal when the first feedback signal is determined to be the NACK signal. A first monitoring interval for monitoring the first feedback signal in order to determine the NACK signal may be set to be different from a second monitoring interval for monitoring the first feedback signal in order to determine the ACK signal.

Abstract: The present invention relates to a method and an apparatus for receiving a reference signal by a terminal in a wireless communication system. According to the present invention, from a base station, a terminal receives configuration information of a channel state information (CSI)-RS resource for transmission of a CSI-RS, and receives the CSI-RS on the basis of the configuration information. Further, provided may be a method and an apparatus, in which a terminal configures a beam on the basis of the CSI-RS, wherein the configuration information includes at least one of a first indicator indicating the number of times the CSI-RS is repeatedly transmitted, a first offset value of a first subcarrier to which the CSI-RS resource is mapped, and information indicating the maximum number of times the terminal can perform beam sweeping, and the CSI-RS resource is mapped to subcarriers at a predetermined interval on a frequency axis, and the CSI-RS can be repeatedly transmitted within a specific time interval according to the first indicator.
