Abstract: A method and apparatus for monitoring downlink control information (DCI) in a wireless communication system, especially in a new radio access technology (NR) is provided. A user equipment (UE) monitors first DCI having a first size in a UE specific search space (USS). The the first size is determined based on an active bandwidth part (BWP). The UE further monitors second DCI having a second size in a common search space (CSS). The second size is determined based on a default BWP.

Abstract: A method and apparatus for communicating with a long-term evolution in unlicensed spectrum (LTE-U) base station (BS) in a wireless communication system is provided. A user equipment (UE) receives a configuration of a potential transmission time unit (P-TTU), communicates with a first LTE-U BS of a first operator based on the configured P-TTU, and communicates with a second LTE-U BS of a second operator based on the configured P-TTU. The communication with the first LTE-U BS and the communication with the second LTE-U BS is multiplexed by time division multiplexing (TDM).

Abstract: The present invention relates to a wireless communication system. Specifically, the present invention relates to a method comprising: configuring a first cell group consisting of a PCell and zero or more SCells, and a second cell group consisting of SCell(s); determining transmit power of a first PUCCH to be transmitted through the PCell; and determining transmit power of a second PUCCH to be transmitted through a predetermined SCell in the second cell group, wherein the transmit powers of the first PUCCH and the second PUCCH are adjusted so that the total sum of transmit power of a terminal is not greater than the maximum transmit power of the terminal, considering a minimum guaranteed power which is assigned to each cell group according to protection priorities between cell groups, and the minimum guaranteed power assigned to each cell group is selectively applied to a specific UCI among a plurality of UCIs.

Abstract: Provided are a method and an apparatus for receiving a downlink signal in a wireless communication system. The method includes receiving resource block assignment information including a bitmap and receiving the downlink signal through a resource block group (RBG) indicated by the bitmap in a bandwidth part. A total number of resource block groups (RBGs) in the bandwidth part is determined based on an index of a start resource block of the bandwidth part, a size of the bandwidth part, and a size of one resource block group.

Abstract: Provided are a method and a device for reporting a power headroom in a wireless communication system. The device receives initial downlink control information (DCI) for physical uplink shard channel (PUSCH) transmission in a first subframe and receives triggering DCI in a second subframe. The device calculates a power headroom on the assumption that the PUSCH transmission is not performed.
