Abstract: Provided is a method and apparatus for receiving a reference signal. A wireless user device may determine, based on a synchronization signal (SS) block index and based on an index associated with a time interval, an initialization value associated with a reference signal for a physical broadcast channel (PBCH). The wireless user device may receive, based on the initialization value and based on a frequency domain shift value, the reference signal via at least one resource element (RE). The reference signal may be mapped, based on the frequency domain shift value, to the at least one RE. The wireless user device may receive the PBCH.

Abstract: An atomizer includes a liquid delivery element configured to absorb an aerosol generating material of a liquid storage and a wire configured to heat the aerosol generating material and wound on a surface of the liquid delivery element, wherein the wire is wound in a spiral shape such that coils of the wire are spaced apart from each other by a certain distance on the surface of the liquid delivery element, one of end portions of the wire is in contact with a first portion of the surface of the liquid delivery element, and the other one of the end portions of the wire is in contact with a second portion of the surface of the liquid delivery element.

Abstract: A cartridge for mounting on a main body of an aerosol generating device includes: a liquid storage extending in a longitudinal direction of the cartridge to form an outer wall of the cartridge, the liquid storage including a space accommodating a liquid composition therein; a heater that heats the liquid composition accommodated in the liquid storage to generate an aerosol; and a coupling protrusion including an elastic material, the coupling protrusion protruding from an outer surface of the liquid storage and coupling the main body to the cartridge.

Abstract: Sidelink downlink control information (SL DCI) associated with transmission of one or more sidelink signals may be communicated. A wireless user device may transmit, based on the SL DCI and to one or more second wireless user devices, the one or more sidelink signals via a first quantity of sidelink channel resources. The wireless user device may receive first sidelink HARQ feedback information responsive to the one or more sidelink signals. The wireless user device may determine, based on a sidelink HARQ feedback timing, a time interval to transmit the first sidelink HARQ feedback information. The wireless user device may determine, based on the first quantity, a sidelink HARQ codebook. The wireless user device may transmit, during the time interval, based on the sidelink HARQ codebook, and to the base station, an uplink signal indicating the first sidelink HARQ feedback information.

Abstract: An aerosol generating device includes a housing including an accommodation space in which an aerosol generating article is accommodated and an air flow path through which fluid moves inside the housing, wherein a volume of the air flow path is variable.

Abstract: An embodiment resin composition for shielding electromagnetic waves, based on a total weight of the resin composition, includes 20 to 80 wt % of thermoplastic resin, 1 to 50 wt % of a conductive filler, and 0.1 to 30 wt % of an additive.
