Abstract: A method and apparatus for transmitting a physical random access channel (PRACH) in a wireless communication system is provided. A user equipment (UE) receives multiple PRACH configurations which include a first PRACH configuration for new radio access technology (NR) downlink/uplink (DL/UL) carrier in a NR band and a second PRACH configuration for a supplemental UL carrier in a long-term evolution (LTE) band, and transmits at least one of a first PRACH for accessing the NR DL/UL carrier in the NL band by using a first PRACH power based on the first PRACH configuration, or a second PRACH for accessing the supplemental UL carrier in the LTE band by using a second PRACH power based on the second PRACH configuration. The first PRACH configuration and the second PRACH configuration include different PRACH power configurations.

Abstract: According to the present invention, a common control signal via a group common control channel (GCCC) for a new radio access technology (NR) is defined. A user equipment (UE) receives the common control signal from a network via GCCC. The common control signal is for all UEs or a group of UEs in a cell. The UE handles the priority of the common control signal compared to other signals. For example, the priority of the common control signal may be higher than a semi-static UE-specifically configured configuration, and may be lower than a cell-commonly or group-commonly configured configuration.

Abstract: A method of receiving Downlink (DL) data by a User Equipment (UE) in a wireless communication system. The method includes: receiving information related to a number of repetitions of the DL data which is repeatedly transmitted in (i) at least one first Transmission Time Interval (TTI) included in a first subframe, and in (ii) at least one second TTI included in a second subframe that is after the first subframe; and receiving the DL data based on the number of repetitions of the DL data. If a Transmission Mode (TM) for the first subframe is different from a TM for the second subframe, then the UE does not receive the DL data in the at least one second TTI.

Abstract: Provided are a method and device for receiving remaining minimum system information (RMSI) in a wireless communication system. User equipment (UE) receives a synchronization signal (SS)/physical broadcast channel (PBCH) block from a network, receives information about an offset between the SS/PBCH block and the RMSI from the network, and receives the RMSI from the network on the basis of the information about the offset between the SS/PBCH block and the RMSI. The offset between the SS/PBCH block and the RMSI can be based on the numerology having a smaller subcarrier interval among the numerology of the SS/PBCH block and the numerology of the RMSI, and, more generally, the numerology having the smaller subcarrier interval among the numerology of the SS/PBCH block and the numerology of the RMSI can be the numerology having the smallest subcarrier interval in each frequency range (FR).

Abstract: Provided are a method of operating a node in a wireless communication system and a device using the same. The method includes: connecting to a parent node through an initial access process; receiving, from the parent node, first allocation information related with communication with the parent node and second allocation information related with communication with a child node; and communicating with the parent node or the child node using a specific resource based on the first allocation information and the second allocation information. When the second allocation information indicates the specific resource as a hard resource that is always available for communication with the child node, the specific resource is used for communication with the child node regardless of the first allocation information.
