Abstract: The method includes receiving first allocation information related to communication with a parent node and second allocation information related to communication with a child node and communicating with the parent node or the child node using a particular resource based on the first allocation information and the second allocation information. The first allocation information indicates a resource type of the particular resource as one of three resource types, the second allocation information indicates the resource type of the particular resource as one of seven resource types. When the second allocation information indicates the particular resource as a soft downlink, soft uplink, or soft flexible resource and when it is not explicitly indicated that the particular resource is available for the communication with the child node, the particular resource is used for the communication with the parent node.

Abstract: The disclosure of the present invention proposes a method for connecting to a base station. The method may be performed by a user equipment (UE) and comprise: receiving information on a UE-specific bandwidth of a first cell. Here, the UE-specific bandwidth of the first cell is variable based on a bandwidth of a second cell using long term evaluation (LTE) radio access technology (RAT). The information on the UE-specific bandwidth may indicate a bandwidth between a bandwidth between a minimum bandwidth and a maximum bandwidth.

Abstract: A method of performing channel estimation of a physical downlink control channel (PDCCH) in a wireless communication system is disclosed. Specifically, the method performed by a user equipment (UE) includes receiving a synchronization signal block (SSB) from a base station, receiving system information (SI) from the base station based on the SSB, transmitting a physical random access channel (PRACH) preamble to the base station, receiving a response to the PRACH preamble from the base station, transmitting UE capability information related to the channel estimation to the base station, receiving information for a PDCCH monitoring duration from the base station, and performing the channel estimation based on the information for the PDCCH monitoring duration. The UE capability information includes information for a maximum number of control channel elements (CCEs) that are capable of the channel estimation per PDCCH monitoring duration.
