Abstract: Provided herein is a method and apparatus for configuring a physical uplink control channel (PUCCH) resource in a wireless communication system and, most particularly, in a new radio access (NR) technology. More specifically, when and/or for which operation the default PUCCH resource is being used may be defined. For example, a wireless device may receive information on a default physical uplink control channel (PUCCH) resource, and the wireless device may transmit uplink control information (UCI) to a gNB by using the default PUCCH resource, only before establishing a radio resource control (RRC) connection with the gNB.

Abstract: The present invention relates to a wireless communication system. More particularly, the present invention relates to a method for transmitting uplink channel state information (CSI) in a wireless communication system that supports carrier aggregation, and to an apparatus for the method. The method for reporting CSI in a wireless communication system that supports carrier aggregation comprises the steps of: configuring a plurality of downlink component carriers (DL CCs); setting a CSI report mode on the plurality of DL CCs for each DL CC; and performing an operation for transmitting CSI according to the CSI report mode set on each DL CC. If a P-number of CSI overlap in the same subframe and a first condition is satisfied, a Q-number of CSI among the P-number of CSI are transmitted through a first physical channel, and if the P-number of SCI overlap in the same subframe and a second condition is satisfied, only an R-number of CSI among the P-number of CSI are transmitted through a second physical channel which is different from the first physical channel, wherein R is smaller than Q.

Abstract: Provided are a method and an apparatus for controlling transmission power in a wireless communication system. A wireless device is connected to a first serving cell utilizing a licensed band and a second serving cell utilizing a non-licensed band. The transmission power from the second serving cell is determined by considering the clear channel assessment (CCA) coverage of the wireless device or the second serving cell.

Abstract: A method and a device for transmitting reference signals in a wireless communication system are disclosed. For these, a sequence is acquired to be used for the reference signals, and the reference signals are transmitted through subframes comprising a first type subframe and a second type subframe. Here, the first type subframe includes a first number of OFDM symbols and the second type subframe includes a second number of OFDM symbols. And, a first position of OFDM symbol for transmitting the reference signals at the first type subframe is the same as a second position of OFDM symbol for transmitting the reference signals at the second type subframe.

Abstract: A method for performing a power scaling is discussed. The method performed by a user equipment (UE) includes determining, by the UE configured with dual connectivity to a master cell group (MCG) and a secondary cell group (SCG), a first power for a first transmission in a first subframe toward the MCG determining a second power for a second transmission toward the SCG, and scaling down the second power for the second transmission toward the SCG if a total power related to the MCG and the SCG exceeds a maximum power, wherein the scaling down is performed if the first transmission toward the MCG in the first subframe is overlapped with the second transmission toward the SCG.

Abstract: A UE transmits a random access channel (RACH) preamble and a BS receives the RACH channel. The BS configures the RACH preamble to align boundaries of the RACH preamble with boundaries of OFDM symbols on which the RACH preamble is configured in the time domain. The UE generates/transmits the RACH preamble to align the boundaries of the RACH preamble with the boundaries of OFDM symbols on which the RACH preamble is configured in the time domain.

Abstract: A method for a wireless device to which a plurality of serving cells are assigned transmitting uplink control information (UCI) in a wireless communication system is provided. The wireless device transmits uplink data in a subframe to a physical uplink shared channel (PUSCH), and transmits UCI including a hybrid automatic repeat request (HARQ) ACK/NACK and periodic channel state information (CSI) in the subframe to a physical uplink shared channel (PUCCH). The PUCCH and the PUSCH have the same demodulation reference signal (DMRS) location within the subframe.
