  • Patent number: 11979749
    Abstract: The present invention relates to a method for transmitting a Physical Uplink Shared Channel (PUSCH), performed by a user equipment (UE) in an unlicensed band, the method comprising: receiving downlink control information (DCI) including information on a listen before talk (LBT) type and information on a PUSCH start position from a base station; and transmitting the PUSCH on the basis of the information on the LBT type and the information on the PUSCH start position, wherein the LBT type is one of LBT type 1, LBT type 2, and LBT type 3, a random backoff-based LBT is performed in the LBT type 1, an LBT without a random backoff is performed in the LBT type 2, and an uplink is transmitted without LBT in LBT type 3.

  • Patent number: 11974148
    Abstract: The present invention relates to a wireless communication system, and specifically to a method and a device therefor, the method comprising: a step for receiving group common DCI on a first cell, wherein the group common DCI includes availability information about one or more RB sets configured for the first cell; a step for, on the basis of all of the RB set(s) being indicated as unavailable, performing first PDCCH monitoring, but skipping channel measurement on the RB set(s) during a certain duration; and a step for, on the basis of at least one of the RB set(s) being indicated as available, performing second PDCCH monitoring and the channel measurement on the at least one available RB set.

  • Patent number: 11950290
    Abstract: A method for transmitting a random access channel (RACH) by a terminal in a wireless communication system is provided. The method comprises: receiving a synchronization signal block (SSB) from a base station; receiving a downlink signal from the base station; and when the reception of the downlink signal is finished, transmitting the RACH to the base station, wherein the SSB is periodically transmitted in every Nth fixed frame period (FFP), N is an integer equal to or greater than 1, and the starting time point for transmission of the SSB corresponds to a first time resource included in the every Nth FFP.

  • Patent number: 11917684
    Abstract: Provided are a method of performing a channel access procedure by an apparatus in an unlicensed band, and an apparatus using same method. The apparatus determines a contention window size (CWS) and performs a channel access procedure with respect to a first channel on the basis of the determined contention window size. The contention window size may be adjusted on the basis of feedback information relating to a second channel. When a transmission history of the second channel, which is to be reflected in determining the contention window size, does not exist, the contention window size may be determined to be a minimum CWS value in a specific channel access priority class.

  • Patent number: 11408110
    Abstract: A washing machine includes a water tank, a washing tub, a pulsator, a drive motor, a drive shaft, a dewatering shaft that rotates about the same axis of the drive shaft and spins the washing tub, a coupler that is mounted to move up and down along the dewatering shaft and transmits the torque of the drive motor to the dewatering shaft, a solenoid module that moves the coupler upward in a lengthwise direction of the dewatering shaft so as to cut off torque from the drive motor to the dewatering shaft or transmit the torque to the dewatering shaft, when a magnetic field is generated by applying an electric current to a coil, and a coupler guide that rotates itself or fixes the position of the coupler, by coming into contact with the coupler when the coupler moves upward in the lengthwise direction of the dewatering shaft.
