A disclosure of the present disclosure provides a method of performing handover-related communication by a source base station. This method includes the steps of: receiving, from a UE, a report message including a measurement result related to at least one relay UE; determining a target path type for the UE; transmitting a handover request message to a first target base station; receiving a handover preparation failure message including a cause value from the first target base station; and re-determining a target path type of the UE.

A method for a terminal to receive a signal in a wireless communication system according to an embodiment of the present disclosure may comprise the steps of: receiving system information including a configuration related to a wake-up signal (WUS) through a first reception operation; and determining, on the basis of the system information, whether to perform monitoring of the WUS through a second reception operation that consumes less power than the first reception operation, wherein the configuration related to the WUS may include information about the waveform of the WUS

There is provided a method performed by a user equipment (UE) in a wireless communication system. The method comprises receiving, from a base station (BS), a master information block (MIB) including configuration information related to a number of consecutive resource blocks for control resource set (CORESET) #0; and receiving, from the BS, a physical downlink control channel (PDCCH) through the CORESET #0 including second resource blocks excluding first resource blocks from the resource blocks based on i) the number of the resource blocks and ii) a channel bandwidth. A puncturing based on a specific number of the first resource blocks among the resource blocks is assumed for the CORESET #0. The PDCCH is received through one or more PDCCH candidates including control channel elements (CCEs) in a search space related to the CORESET #0. Indexes of the CCEs related to the one or more PDCCH candidates are based on a number of the CCEs, and the number of the CCEs is based on the CORESET #0 before the puncturing.

Disclosed are a method and an apparatus for setting up and maintaining a session in an ultra-wideband wireless network system. A method performed by a first device in an ultra-wideband (UWB) wireless network system according to an embodiment of the present disclosure may comprise the steps of: transmitting an advertising poll frame to a second device; receiving an advertising response frame from the second device; and transmitting a start-of-ranging (SOR) frame to the second device. On the basis that the advertising response frame is a public advertising response frame, the public advertising response frame may include a responder address which is a public address randomly generated by the second device.

Proposed is an operational method of a first device (100) in a wireless communication system. The method comprises the steps of: receiving, in a first time domain, a first inter-device reference signal from a second device (200), on the basis of a first angle; and transmitting, in the first time domain, a second inter-device reference signal, on the basis of a second angle obtained by applying a first angular difference to the first angle, wherein one or more angle differences including the first angular difference may be associated with one or more time domains, respectively.

Provided are a method by which a first device performs wireless communication and an apparatus supporting same. The first device can transmit a first signal to a first node, and the first device can receive, from a second node, a second signal acquired on the basis of reflection of the first signal from the first node, the second node, and a third node having the position known. For example, the first signal reflected from the first node on the basis of a first angle gap can be reflected from the third node and then reflected from the second node on the basis of a second angle gap, and the position of the first device can be acquired on the basis of the first signal and the second signal.

A refrigerator of the present disclosure comprises: a door withdrawn forward from a storage space of a cabinet; and an open module provided on the door. The open module includes: a handle which is disposed inside the door so as to be rotatable with respect to a rotational center in the left-right direction, and which includes an operating part that is exposed through an opening provided in a front panel of the door and that is positioned to be higher than the rotational center, and a lever that is positioned to be lower than the rotational center; a link including a link rotary shaft, which is positioned to be lower than the rotational center of the handle, a first arm, which extends upward from the link rotary shaft and is positioned in front of the lever, and a second arm, which extends downward from the link rotary shaft; and a pusher disposed at the rear of the second arm, and provided to be slidable backward.

A refrigerator of the present disclosure may comprise: a cabinet for providing a storage space; a door for opening and closing the storage space; a handle receiving external force so as to rotate around a first axis; and a pusher, which receives the external force so as to move the door far away from the cabinet when the door is opened.

There is provided a method performed by a user equipment (UE) in a wireless communication system. The method comprises receiving, from a base station (BS), an MIB including configuration information related to a number of contiguous resource blocks for control resource set (CORESET) #0 through a physical broadcast channel (PBCH) signal; and receiving, from the BS, a physical downlink control channel (PDCCH) through the CORESET #0 including second resource blocks excluding first resource blocks from the resource blocks based on i) the number of resource blocks and ii) a channel bandwidth. A puncturing based on a specific number of first resource blocks among the resource blocks is assumed for the CORESET #0. The PBCH signal includes information of a resource offset related to the CORESET #0, and the PDCCH is received in a search space related to the CORESET #0 based on the resource offset.

This UE may: receive a cell DRX configuration relating to a first cell in which PUCCH resources are configured; on the basis of the cell DRX configuration relating to the first cell, determine an active period in which uplink transmissions of the first cell are not restricted and a non-active period in which uplink transmissions of the first cell are restricted; and on the basis that the first cell is in the active period, perform PDCCH monitoring for a second cell using the first cell for PUCCH transmissions.

A method performed by a user equipment (UE) according to an embodiment of the present disclosure includes receiving configuration information related to a serving cell, receiving downlink control information (DCI) for scheduling of a physical uplink shared channel (PUSCH), and transmitting the PUSCH based on an uplink timing which is related to one of a first timing advance group (TAG) and a second TAG. A TAG related to the uplink timing is determined based on a sounding reference signal (SRS) resource.
