  • Patent number: 10980014
    Abstract: The present invention is designed so that, when special subframes are allowed to transmit a PUSCH, the transmission of the PUSCH can be controlled adequately. According to the present invention, a user terminal has a receiving section that receives downlink control information (DCI) that schedules an uplink (UL) shared channel, and a control section that controls transmission of the UL shared channel by using a table that associates a subframe, in which the DCI is received, and a timing, at which the UL shared channel is transmitted, per UL/downlink (DL) configuration. The transmission timing in the table is determined based on a special subframe, which is allowed to transmit the UL shared channel, and a predetermined reference value, which is lower than 4 ms.

  • Patent number: 10680680
    Abstract: This specification discloses methods and systems providing reader-mode performance enhancement for operating a device that communicates via inductive coupling. In reader-mode, Tx (transmitter) power of a reader device is maximized even though for some tags, the communication distance is limited by Rx (receiver) sensitivity. Therefore, power is wasted. Even worse, a too highly boosted Tx power demands a high Rx dynamic range and consequently a low Rx sensitivity. In turn, the communication distance may even be degraded by a too highly boosted Tx power. Therefore, in some embodiments, reader-mode performance enhancement is based on backing off Tx (transmitter) power when not needed (energy distance>communication distance) to save power and/or to relax reader-mode Rx (receiver) sensitivity requirements. In some embodiments, the backing off of Tx (transmitter) is also based on a sensor determining a geometric position/location of a reader device relative to a tag-mode device.

  • Patent number: 10362558
    Abstract: A radio network node receives a page request from a core network node. The page request indicates to page a wireless communication device. The radio network node determines a next occurrence of a monitoring window during which the wireless communication device will monitor a paging channel associated with the radio network node. If the amount of time until the next occurrence of the monitoring window exceeds an amount of time that the radio network node can store the page request, the radio network node discards the page request and sends a response to the core network node indicating that the page request was discarded; the response includes a paging timer value that indicates when the core network node should repeat the page request.

  • Patent number: 10355750
    Abstract: A method for a communication device includes determining whether a first radio frequency (RF) signal at a level of at least a first predetermined field threshold is detected. The method also includes generating a second RF signal at a level of at least a second predetermined field threshold greater than the first predetermined field threshold, when the communication device receives an instruction to generate the second RF signal and the determining determines that the first RF signal at the level of at least the first predetermined field threshold is not detected. The method further includes receiving a load modulated RF signal in response to the second RF signal.

  • Patent number: 10331991
    Abstract: An RF tag circuit including a power storage unit is provided, in which an increase in time required for a voltage change occurring when an impedance is adjusted is reduced. The RF tag circuit is connected to an antenna and a load. The RF tag circuit includes a rectification circuit, a matching circuit, a power storage unit, and a control unit. The rectification circuit rectifies a radio wave received by the antenna and supplies DC power. The matching circuit, of which an impedance is changeable, is interposed between the antenna and the rectification circuit. The power storage unit stores DC power input from the rectification circuit and supplies the stored DC power to the load. The control unit disconnects the power storage unit from the RF tag circuit and adjusts the impedance of the matching circuit such that the amount of the power supplied by the rectification circuit increases.

  • Patent number: 10312570
    Abstract: A long-distance radio frequency anti-metal identification tag is provided. When a bottom surface of an insulating spacer plate is attached to the surface of a metal object and an electronic tag reading device is used to read a radio frequency identification chip on a second antenna. A resonant cavity is formed between a slot of a first antenna and the surface of the metal object through the isolation of the insulating spacer plate, such that the second antenna located at the position of the resonant cavity resonates with an electromagnetic wave signal reflected on the surface of the metal object by the first antenna. The electromagnetic wave signal is transmitted to the radio frequency identification chip, or the feedback signal of the radio frequency identification chip is transmitted out. The overall UHF electronic tag is resistant to a metal interference and has the performance of long-distance reading.

  • Patent number: 10305685
    Abstract: An identification information transmitter encrypts identification information for identifying a person or an object using an encryption key, transmits the encrypted identification information, and, after receiving another encryption key, switches the encryption key from the encryption key to the other encryption key. A server receives the encrypted identification information from the identification information transmitter, determines whether the encryption key is to be switched, and, if the encryption key is to be switched, generates the other encryption key. Another server authenticates the identification information that an identification information receiver receives from the identification information transmitter, and, if authentication is successful, acquires the other encryption key from the server, and transmits the other encryption key to the identification information receiver.
