  • Patent number: 10368339
    Abstract: To allocate resources for a device-to-device discovery and/or communication to a user equipment, the user equipment receives information on allocated resources while the user equipment is connected to a mobile communication network. The user equipment continues a usage of the allocated resources for a device-to-device discovery and/or a device-to-device communication when the user equipment is in an idle mode.

  • Publication number: 20190014573
    Abstract: To adjust a transmit power for device-to-device communication, a user equipment which performs the device-to-device communication using the transmit power detects that the user equipment enters a coverage area of a radio communication unit. The transmit power of the user equipment for the device-to-device communication is decreased in response to detecting that the user equipment enters the coverage area of the radio communication unit.

  • Patent number: 10064193
    Abstract: To allocate resources for a device-to-device discovery and/or communication to at least one user equipment of a mobile communication network, the at least one user equipment is informed of a change of the resources allocated for the device-to-device discovery and/or communication from first allocated resources to second allocated resources. To inform the at least one user equipment of the change, a base station or a user equipment which act as central controller for a group of users of the mobile communication network transmits information on the second allocated resources in at least one physical resource element of the first allocated resources.

  • Publication number: 20180131133
    Abstract: Embodiments of the present invention provide a press tool and an electronic product detecting apparatus including the press tool. The press tool includes: a connector soft-contact member including: a first base plate; a floating plate mounted to the first base plate; and a buffer member mounted between the first base plate and the floating plate and configured such that when receiving a pressing force, the buffer member generates a repulsive force, so that the floating plate is floatable; and a press member connected with the connector soft-contact member such that they are openable and closable relative to each other. The press member includes a second base plate and a connector bearing piece which is mounted to the second base plate and which is positioned just opposite to the floating plate when the connector soft-contact member and the press member are closed.

  • Publication number: 20170041941
    Abstract: Embodiments are directed to systems, methods and computer program products for enhancing contention-based device to device (D2D) resource allocation, where resources are allocated on a non-user device specific basis. Embodiments include initiating communication, by a first user device, a resource request message (RR) to a second user device; receiving, by the first user device from the second user device and in response to the resource request message, an acknowledge to transmit message (AT); and in response to receiving the AT, initiating a first data communication session, by the first user device, between the first user device and the second user device.

  • Publication number: 20170013578
    Abstract: To attain a synchronization for a device-to-device discovery and/or a device-to-device communication, a user equipment determines whether it is enabled to transmit a synchronization signal (65) for the device-to-device discovery and/or the device-to-device communication The user equipment has a wireless interface configured for communication with a radio access network of a mobile communication network. The user equipment selectively transmits the synchronization signal (65) for the futflled device-to-device discovery and/or the device-to-device communication over the wireless interface to at least one further user equipment.
