  • Patent number: 9681414
    Abstract: A wireless terminal (30) capable of operating in a discontinuous mode and method for operation facilitate measurements pertaining to position of the wireless terminal (30). A measurement request message from a radio access network (28) indicates that measurements are to be performed by the wireless terminal on downlink signals transmitted by the base station or by the base station on downlink signals transmitted by the base station. As a result of or after receiving the message, operation of the wireless terminal (30) changes from a discontinuous mode to a modified mode to facilitate performance of the measurements. Relative to the discontinuous mode at least one of following are shortened or eliminated in the modified mode: (i) the non-reception periods, and (ii) the non-transmission periods.

  • Patent number: 9681394
    Abstract: A method for power control and a user equipment, UE, determine a current power control mode of the UE based on an adjustment trend of the UE with respect to signal transmission power of a base station, and a variation trend of the received signal quality. A target value of the received signal quality of inner-loop power control is reset after the power control mode of the UE tends to normal, so as to return the transmission power of the base station to the UE to a normal level as soon as possible, thereby to inhibit adverse influences caused by the windup effect.

  • Patent number: 9660750
    Abstract: Provided is a radio communication device which can suppress inter-code interference between an ACK/NACK signal and a CQI signal which are code-multiplexed. A diffusion unit (214) diffuses the ACK/NACK signal inputted from a judgment unit (208) by using a ZC sequence. A diffusion unit (219) diffuses the CQI signal by using a cyclic shift ZC sequence. By using a Walsh sequence, a diffusion unit (216) further diffuses the ACK/NACK signal which has been diffused by using the ZC sequence. A control unit (209) controls the diffusion unit (214), the diffusion unit (216), and the diffusion unit (219) so that the minimum value of the difference between the CQI signals from a plurality of mobile stations and a cyclic shift amount of the ACK/NACK signal is not smaller than the minimum value of the difference between the cyclic shift amounts of the ACK/NACK signals from the plurality of mobile stations.

  • Patent number: 9648642
    Abstract: Integrated circuitry for use in a mobile radio station includes a receiver that receives control information and a data processor coupled to the receiver. The data processor provides a number of different sequences that are derived from a base sequence. The different derived sequences are respectively associated with different amounts of data or reception qualities, have different cyclic shifts, and are arranged in an increasing order of the cyclic shifts. The data processor randomly selects a sequence from a subset of the derived sequences. The subset of derived sequences depends on the control information.

  • Patent number: 9602708
    Abstract: A method of generating first and second panoramic pictures based on a series of frames acquired by a frame acquisition device is provided. While the device is panned in a main direction, a global motion value reflecting a displacement in the main direction between consecutive frames and a perspective transform reflecting a perspective change between the frames are computed. For each frame, a first area of the frame is determined for the first panoramic picture and a second area of the frame, distinct from the first area, is determined for the second panoramic picture. An adapted first area is determined by applying an inverse of the global transform to the first area of the current frame, the adapted first area being included into the first panoramic picture and the second area of the current frame being included into the second panoramic picture.
