Abstract: In the present invention, when a UE transmits a random access preamble, the UE maintains a power ramping counter used for determination of a transmission power equally to a value of previous transmission without incrementing the power ramping counter if a target synchronization signal block is changed differently from a previous random access preamble transmission.

Abstract: The present invention relates to a method and a device for transmitting a device-to-device (D2D) signal of a first terminal in a wireless communication system. Particularly, the method comprises the steps of: receiving at least one parameter for D2D communication which includes a scheduling assignment identity (ID); and transmitting a D2D signal generated by using the scheduling assignment ID to a second terminal through an uplink subframe, wherein the scheduling assignment ID is associated with the second terminal for the D2D communication.

Abstract: Provided are a method for transmitting uplink control information (UCI) of a terminal in a wireless communication system and the UE using the method. The method includes determining a number of coded symbols for the UCI transmission and transmitting the UCI on a physical uplink shared channel (PUSCH) based on the number of coded symbols. The number of coded symbols is determined among a first value based on a payload size of the UCI and an offset value and a second value based on a radio resource control (RRC) signal.

Abstract: A method is provided for receiving a user equipment (UE) specific reference signal based-downlink data channel by a UE in a wireless communication system. The UE receives, from a network, a downlink control channel including either first scheduling information or second scheduling information, and receives the UE-specific reference signal based-downlink data channel from the network based on the downlink control channel. When the downlink control channel includes the first scheduling information, antenna ports of a certain reference signal which can be assumed to be quasi co-located with antenna ports of a UE-specific reference signal is configured by an indicator indicating one of two or more parameters configured by a higher layer. When the downlink control channel includes the second scheduling information, the antenna ports of a certain reference signal is configured by a parameter of a minimum index among the two or more parameters.

Abstract: The present invention discloses a method for transmitting a reference signal and a device therefor in a wireless communication system. In particular, the method maps and transmits a DMRS signal to at least one OFDM symbol in a resource region for uplink data, and in the at least one OFDM symbol, a resource element to which the DMRS signal has not been mapped cannot be used for the uplink data.
