  • Publication number: 20200296719
    Abstract: A mobile station apparatus configures first and second timers related to first and second groups. A first group of cells uses a first uplink transmission timing, and a second group of secondary cells uses a second uplink transmission timing. When the first timer of the first group has expired: all transmission HARQ buffers in association with the cells of the first group are flushed, the second timer is considered as expired, and an uplink transmission on any cells except random access preamble transmission on the primary cell is stopped. In a case where the second timer of the second group has expired: all transmission HARQ buffers in association with the secondary cells of the second group are flushed, and an uplink transmission on any cells in the second group except random access preamble transmission on the any cells in the second group is stopped.

  • Patent number: 8031378
    Abstract: There is provided an image forming device that does not require an original image scanning operation upon copying of an original for the second time or later in a device for preventing illegal copying with the use of paper fingerprint information. Upon registration of the paper fingerprint information, original image data is scanned from the original. Also, the paper fingerprint information is scanned. The image forming device associates the original image data and the paper fingerprint information with each other to register them in an information processing device. Upon copying, paper fingerprint information scanned from an original is transmitted to the information processing device to request the device to determine whether or not the paper fingerprint information has been registered. If the paper fingerprint information has been registered is received, the original image data registered in association with the paper fingerprint information is retrieved from the information processing device.
