A method and a device for transmitting and receiving a signal in a wireless communication system, disclosed in the present specification, operate on the basis of a cell DTX/DRX configuration and a terminal DRX configuration. Specifically, a signal based on a configuration for one of an SSB, an SIB, a RACH, and paging can be transmitted and received at different periods according to a cell DTX active/inactive duration and a cell DRX active/inactive duration of the cell DTX/DRX configuration.

Disclosed are a method and an apparatus for saving network energy in a wireless communication system. A method performed by a terminal according to an embodiment of the present disclosure may comprise the steps of: receiving pattern information of at least one of an active period and an inactive period of cell-related DTX or DRX; receiving configuration information related to a random access process; receiving DCI including information indicating a specific resource for the random access process as a resource available for transmission or a resource unavailable for transmission; and performing the random access process on the basis of the pattern information, the configuration information, and the DCI. Here, on the basis that the specific resource is indicated as a resource unavailable for transmission, the random access process may be performed by invalidating at least one of a RACH opportunity or a RACH preamble related to the specific resource.

The purpose of the present disclosure is to support data forwarding in a wireless communication system, and a method performed by a first network node may comprise the steps of: transmitting a secondary node (SN) addition request message to a second network node; and receiving an SN addition request confirmation message from the second network node.

The present disclosure relates to a robot cleaner station. The robot cleaner station includes a housing, a seating portion disposed in the housing and to which at least a portion of a robot cleaner is coupled, and a dust collection portion configured to collect dust from an interior of a dust bin of the robot cleaner. The dust collection portion includes a dust collection portion housing into which dust in the dust bin is introduced, a dust collection motor configured to provide a suction force for suctioning the dust in the dust bin, and a dust collection portion base configured to support the dust collection portion housing and the dust collection motor. The dust collection portion base forms a flow path for discharging air introduced into the dust collection portion housing toward the dust collection motor. Accordingly, a component used for dust collection also serves to form the flow path, thereby providing an effect of securing a larger space compared to a case where a separate hose or pipe is used.

A method and a device for supporting protection of a control frame in a wireless LAN system are disclosed. The method performed by a first STA in a wireless local area network (WLAN) system, according to one embodiment of the present disclosure, may comprise the steps of: identifying key information related to protection of a control frame; receiving, from a second STA, the control frame to which the protection is applied; generating, on the basis of the control frame, additional authentication data (AAD) related to the protection; and performing decoding and/or integrity checking on the control frame on the basis of the key information and the AAD. Here, the AAD can have at least one field in a MAC header of the control frame, or can have a combination of at least one field in the MAC header of the control frame and at least one field in a frame body.
