  • Publication number: 20200305075
    Abstract: A mobile terminal 3 judges whether or not the mobile terminal is able to make a transition to a DTX period during Active, and, when judging that the mobile terminal is able to make a transition to a DTX period during Active, notifies a base station 2 to that effect. If the base station 2 judges that the mobile terminal is able to make a transition to a DRX period during Active when triggered by the notification from the mobile terminal 3, the base station temporarily stops supply of electric power to the data transmission processing units and the data reception processing units of the mobile terminal 3.

  • Publication number: 20200145677
    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.

  • Publication number: 20200120515
    Abstract: A communication system is provided that, if a large number of small cells are installed, is capable of configuring an operation suitable for small cells through simple operation and administration. If a small cell installed in Step ST1401 judges in Step ST1403 that a coverage macro cell, which includes the small cell in the coverage of the coverage macro cell, is present as a result of neighbor cell search in Step ST1402, notifies the coverage macro cell and another neighbor cell of its own capability in Steps ST1404 and 1405. The coverage macro cell selects a configuration parameter suitable for the capability of the small cell in Step ST1406 and notifies the small cell in Step ST1407. The small cell recognizes an operation mode configured by the coverage macro cell from the configuration parameter notified from the coverage macro cell, and then, starts operating in the operation mode.
