  • Patent number: 11184874
    Abstract: Disclosed are methods for transmission and reception of a paging channel between user equipment (UE) and a base station in a wireless communication system. In particular, the present invention may comprise the steps of: receiving, in a paging occasion of UE, a control channel for a paging channel; attempting to receive the paging channel on the basis of downlink control information (DCI) including information indicating a retransmission time of the paging channel; and if reception of the paging channel fails, reattempting to receive the paging channel at the retransmission time indicated by the DCI.

  • Publication number: 20210343816
    Abstract: An organic light-emitting display device includes a driving transistor configured to control current to an organic light-emitting diode from a power voltage line, a compensation transistor configured to diode-connect the driving transistor in response to a voltage applied to a compensation gate electrode of the driving transistor, and a gate insulating layer interposed between a driving active region of the driving transistor and the driving gate electrode, and between a compensation active region of the compensation transistor and the compensation gate electrode. A dielectric constant in a first portion of the gate insulating layer between the driving active region and the driving gate electrode is greater than a dielectric constant in a second portion of the gate insulating layer between the compensation active region and the compensation gate electrode.

  • Publication number: 20210327926
    Abstract: A substrate processing apparatus includes a first process chamber in which a target substrate is processed, a first tank connected to the first process chamber to supply a first chemical to the first process chamber, a second process chamber in which the target substrate is processed, and a second tank connected to the second process chamber to supply a second chemical to the second process chamber. A metal ion contained in the first chemical supplied to the first process chamber has an ion concentration greater than an ion concentration of the metal ion contained in the second chemical supplied to the second process chamber.

  • Patent number: 11153911
    Abstract: The present invention relates to a communication between MAC layer entity and PHY layer entity for parallel random access procedures of dual connectivity. In this scheme, a first PHY entity of a user equipment informs a failure of a random access preamble transmission to a first MAC entity of the UE. Then, the first MAC entity continues or stops a random access procedure without performing procedures for a random access failure.

  • Patent number: 11129206
    Abstract: The present invention relates to MAC layer communication for parallel random access procedures of dual connectivity. In this scheme, a first MAC entity of a user equipment informs the initiation of the first random access procedure to a second MAC entity of the UE; and informs the completion of the first random access procedure to the second MAC entity, when the first random access procedure is finished.

  • Patent number: 9994251
    Abstract: A method for controlling an output of a power steering system may include sensing at least one of a driving speed of a vehicle, a steering angle, a steering angular velocity, and a steering torque; obtaining a target steering torque by using at least one of the driving speed, the steering angle, the steering angular velocity, and the steering torque; and determining a motor assist output of the power steering system by using the target steering torque.
