  • Patent number: 9723517
    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.
