Disclosed is a turbo compressor. In the turbo compressor, a radial bearing is composed of a gas foil bearing including a bump foil, and a thermal deformation member made of a different material than the bump foil may be in close contact with one side of the bump foil. Accordingly, as the bearing gap between the radial bearing and a rotary shaft is actively varied in accordance with the operation speed of the rotary shaft, the radial direction of the rotary shaft can be more stably supported than by increasing the rigidity of the bump foil.

Provided are a method for a first device to perform wireless communication and a device for supporting same. The method may comprise the steps of: transmitting, on a physical control channel to a second device, first control information for scheduling a physical shared channel and second control information; and transmitting, on the physical shared channel to the second device, the second control information including sharing information, which includes data and an additional identity (ID) for channel occupancy time (COT) sharing related to a third device, about channel occupancy. For example, a timer related to an active time of the third device may start on the basis of the transmission of the second control information including the sharing information, which includes the data and the additional ID for COT sharing related to the third device, about channel occupancy.

According to various embodiments of the present disclosure, there is provided a method performed by a user equipment (UE) in a wireless communication system. The method may comprise receiving, from a first device, downlink control information (DCI) in a first band, receiving, from the first device, a first signal including a first synchronization symbol and first channel state information reference signal (CSI-RS) symbols in a second band, receiving, from second devices, second signals including second CSI-RS symbols in the second band, performing a measurement on the first signal and the second signals based on the first CSI-RS symbols and the second CSI-RS symbols, transmitting, to the first device, a result of performing the measurement in the first band, and receiving data from at least one of the first device or the second devices in the second band.

A user equipment (UE) including a receiver configured to receive a message corresponding to a Soft Vehicle to Everything (V2X) message transmitted by a Message Queuing Telemetry Transport (MQTT) server using MQTT communication or a Soft V2X Bluetooth Low Energy (BLE)-related broadcast message transmitted by another UE using BLE communication; and a controller including a message broker configured to determine whether the received message is the Soft V2X BLE-related broadcast message or the Soft V2X message transmitted by the MQTT server based on identification information included in a payload of the received message, in response to the received message being determined as the Soft V2X BLE-related broadcast message, perform filtering on the received message based on a comparison between an operation mode of the UE and an operation mode of the other UE, and in response the received message being determined as the Soft V2X message transmitted by the MQTT server, process the received message without the filtering.
