  • Patent number: 9924417
    Abstract: A method and apparatus are provided for updating a sequence hopping (SH) pattern of an uplink channel during handover from a current cell having a current SH pattern. At least one downlink channel of each neighbor cell of the current cell is monitored. Information indicative of the monitored downlink channels of the neighbor cells is transmitted to the current cell. Prior to receiving a handover command from the current cell a target cell from among the neighbor cells is anticipated and a common downlink channel of the anticipated target cell is monitored to determine information representative of a target SH pattern of the target cell.

  • Patent number: 9848364
    Abstract: The subject matter described herein relates to data communication in wireless communication systems. The device determines availability of scheduled serving cell before data communication and informs a device the determined availability of the scheduled serving cell. Depending upon the determined availability, the device is controlled to perform the data communication on the scheduled serving cell or another available serving cell. In this way, the unfinished data communication, for example, retransmission of a data block in an uplink or downlink HARQ process can be continued on an available serving cell, whereby avoiding large transmission delay and throughput loss in the wireless communication system.

  • Patent number: 9843798
    Abstract: An encoding/transmitting apparatus that is used to transmit moving-picture data from a transmitting side to a receiving side through a transmission path and to subject the moving-picture data to streaming in the receiving side has an external-output request determining unit that monitors the state of a network. If the network assumes an undesirable state, the request determining unit causes a multiplex output unit to stop multiplexing data. When the network assumes a desirable state, the multiplex unit starts multiplexing the data again. A video encoding unit and an audio encoding unit keep encoding data, whether the multiplex output unit is multiplexing data or not. When the area occupied by encoded data in an encoded-video-data storage unit and the area occupied by encoded data in an encoded-audio-data storage unit exceed a predetermined value, the encoding units stop encoding data, and wait until the area occupied by encoded data sufficiently decreases.
