Syuuichi OKADA has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9750032
    Abstract: A P cell communication unit and an S cell communication unit establish communication with a mobile station using a plurality of radio resources of a first cell and a second cell overlapping the first cell. A moving speed measuring unit measures a moving speed of the mobile station based on a signal transmitted from the mobile station using the radio resources of the first cell. A scheduling processing unit stops an allocation of the radio resources of the second cell to the mobile station based on a wireless environment with the mobile station. The scheduling processing unit starts an allocation of the radio resources of the second cell to the mobile station when the moving speed of the mobile station is less than a certain value in a state in which the allocation of the radio resources of the second cell is stopped.

  • Patent number: 8982756
    Abstract: An intermittent reception control apparatus controls intermittent reception in communication between a base station apparatus and mobile station apparatuses. The intermittent reception control apparatus comprising a control unit that generates DRX parameters, which are intermittent reception parameters, and transmits the generated DRX parameters to the mobile station apparatuses. Further, the DRX parameters include information on the timing at which to cause the mobile station apparatuses to enter an active state and are common to all of the mobile station apparatuses, where the active state is a state where reception of signals transmitted from the base station apparatus is enabled. The intermittent reception control apparatus further comprising a scheduler that transmits to the mobile station apparatuses a DRX command that operates to force these apparatuses to enter an inactive state.
