  • Publication number: 20220238625
    Abstract: A displaying base plate includes a displaying region and a non-displaying region; the non-displaying region includes a substrate, and a first wiring unit, a first planarization part, at least one blocking wall, a second planarization part and a packaging layer located on the substrate; the first wiring unit is provided with a slot; the first planarization part and the blocking wall are provided on one side of the first wiring unit further away from the substrate; the first planarization part is closer to the displaying region than the blocking wall; orthographic projections of the first planarization part on the substrate and the blocking wall on the substrate do not intersect or overlap; the second planarization part is configured to at least fill and level up the slot in the first wiring unit that is located at the region between the first planarization part and the blocking wall.

  • Publication number: 20220183074
    Abstract: A random access method and an apparatus. In the method, random access is completed in a manner in which an agent terminal performs access, so that an access requirement of a terminal can be satisfied under low energy consumption. The method and the apparatus may be applied to application scenarios such as an internet of things (IoT), machine type communication (MTC), massive machine type communication (mMTC), an internet of vehicles, and a connected vehicle.

  • Publication number: 20220183029
    Abstract: This application provides a method for sending and receiving control information, an apparatus, and a system. A transmit end sends control information on a data channel, so that a receive end does not need to monitor a control channel through blind detection within a period of time that is after the receive end receives the control information. This can reduce power consumption of the receive end, and also reduce detection complexity caused by blind detection. In addition, attribute information of a demodulation reference signal (DMRS), a start position of a time domain resource and/or a frequency domain resource occupied by the data channel, or a parameter in semi-persistent transmission (SPS) information is used to indicate whether the control information is carried on the data channel. In this way, the receive end can correctly receive the control information, and signaling overheads can be effectively reduced.

  • Publication number: 20220174602
    Abstract: This application provides a data transmission method and an apparatus, to reduce a quantity of times of repeated transmission of data, reduce power consumption of a terminal device, save transmission resources, and maintain a high time diversity gain. The method includes: A network device sends first information, and a terminal device receives the first information, where the first information is used to configure K repeated transmission occasions. The network device and the terminal device repeatedly transmit first data on N repeated transmission occasions in the K repeated transmission occasions, where the N repeated transmission occasions are discontinuous in time domain, K is an integer greater than 1, and N is an integer greater than or equal to 1 and less than K.

  • Publication number: 20220148338
    Abstract: A method with liveness testing may include: acquiring an infrared (IR) image including an object, and a depth image including the object; generating a first preprocessed IR image by performing first edge enhancement preprocessing on the IR image; generating a preprocessed depth image by performing second edge enhancement preprocessing on the depth image; and determining whether the object is a genuine object based on the first preprocessed IR image and the preprocessed depth image.

  • Patent number: 11200201
    Abstract: A metadata storage method, device, and a server are disclosed. The method includes: obtaining a metadata to be processed from the preset metadata storage system or from external of the preset metadata storage system; determining a type of metadata to be processed; processing the metadata to be processed to obtain a new metadata in a storage format corresponding to the type of metadata to be processed, wherein the storage formats correspond to different types of metadata to be processed and comprise at least one identical information kind for different types of metadata; and storing the new metadata in the preset metadata storage system. Thus a search for a metadata can be performed through a unified interface in a search engine, which is convenient to use.
