  • Publication number: 20160044636
    Abstract: An apparatus performs in parallel a first communication conforming to a first wireless communication method and a second communication conforming to a second wireless communication method by distributing transmission data to the first communication and the second communication so that first and second transmission data are distributed to the first and second communications, respectively. The apparatus detects an unallocated data amount indicating an amount of a first portion of the first transmission data that is different from a second portion of the first transmission data that is allocated to wireless resources of the first communication. The apparatus controls, based on the detected unallocated data amount, a ratio of an amount of the first transmission data distributed to the first communication, to a total amount of transmission data distributed to both the first and second communications.

  • Patent number: 9144000
    Abstract: In a cellular mobile communication system that operates in a first state in which UE has not established a connection with eNB and in a second state in which the connection has been established with eNB, the UE transmits cell selection history to the eNB of a second cell when handover from a first cell to the second cell in accordance with second criteria for handover in the second state, the cell selection history containing a history of cell selection performed in accordance with first criteria for cell reselection in the first state. When the UE performs handover from the first cell to the second cell within a period after transition from the first state to the second state, the eNB of the second cell specifies the cell in which the first criteria and the second criteria are not aligned from among the first cell and the second cell.
