  • Publication number: 20220030349
    Abstract: Embodiments of this application disclose a noise cancellation apparatus and method. The noise cancellation apparatus includes a main control unit and a noise cancellation processing circuit. The main control unit determines a noise cancellation parameter based on a noise cancellation level index or a feature value for determining a matching degree between a headset and an ear canal of a user. The noise cancellation processing unit obtains an inverse phase noise of an ambient noise based on the noise cancellation parameter. After the inverse phase noise is mixed with a played downlink audio signal, the ambient noise can be canceled. In addition, because the noise cancellation parameter is determined from a preset noise cancellation parameter library based on the received or autonomously determined noise cancellation level index, instead of being uniformly configured, a noise cancellation level can be flexibly adjusted, thereby improving a noise cancellation effect and user experience.

  • Publication number: 20220030630
    Abstract: When a channel is not occupied within a first COT, a network device sends indication information to a terminal device within the first COT, where the indication information is used to indicate that the channel is not occupied within the first COT. When the channel is occupied within the first COT, the network device obtains a second COT within the first COT, and sends start information of the second COT to the terminal device. Correspondingly, when receiving the indication information, the terminal device may perform blind PDCCH detection in a first manner. If the terminal device does not receive the indication information, it indicates that the channel is occupied within the first COT, and the terminal device performs blind detection on the start information of the second COT.

    Abstract: An organic film is patterned without applying a hard mask or photolithography. A hydrophilic solvent-soluble resist is placed and arranged on the organic film using a non-lithography process. The hydrophilic solvent-soluble resist is placed and arranged using a printing or lamination process. The organic film is patterned using a wet etchant that is selective to the organic film but non-selective to the hydrophilic solvent-soluble resist. The hydrophilic solvent-soluble resist protects the underlying organic film from contamination and damage, prevents undercutting, and assists in providing a desired taper profile during patterning.
