  • Publication number: 20240073787
    Abstract: A closed subscriber group (CSG) cell allows use of subscribers. To receive the service by the CSG cell, a CSG-ID is notified to a user equipment, but cannot be obtained outside the reach of radio waves from a non-CSG cell. Base stations respectively provided to a CSG cell and a non-CSG cell, and access is made to the CSG cell with the use of a CSG-ID issued when use of the CSG cell is allowed, the base station refers to the notified identification information of a user equipment and then transmits a tracking area update request from the user equipment to a core network. The core network determines whether the user equipment is allowed to use the CSG cell and, if allowed, transmits a signal for assignment of radio resources to the user equipment and the CSG-ID. The user equipment accesses the CSG cell with the CSG-ID.

  • Patent number: 11218714
    Abstract: An image decoding apparatus decodes a bit stream generated by coding an image and decodes coded data included in the bit stream and corresponding to a target block to be decoded in the image. The apparatus includes a first determining unit configured to determine whether the target block is prediction-coded or palette-coded; a second determining unit configured to determine whether or not a pixel in the target block is escape-coded if the first determining unit determines that the target block is palette-coded; and a first decoding unit configured to decode the target block by using a second quantization parameter different from a first quantization parameter if the second determining unit determines that the pixel is escape-coded. The first quantization parameter is used to decode the coded data in a case where the first determining unit determines that the target block is prediction-coded.

  • Patent number: 11115670
    Abstract: The present invention relates to specification of a tile capable of being independently processed to process a certain area at high speed in encoding and decoding of tiles resulting from division of an image in hierarchical coding of the image. An image encoding apparatus that performs the hierarchical coding of an input image with multiple layers includes an acquiring unit and an encoding unit. The acquiring unit acquires a first image generated from the input image and a second image having resolution different from that of the first image. In the encoding of a first area in the first image acquired by the acquiring unit, the encoding unit performs the encoding using a second area existing at the relatively same position as that of the first area in the first image in the second image as a reference image.
