COMMUNICATION CONTROL DEVICE, RADIO COMMUNICATION DEVICE, COMMUNICATION CONTROL METHOD, AND RADIO COMMUNICATION METHOD

摘要

When performing communication by compensating an insufficient band in a radio communication channel by using other radio communication channel, it is possible to transmit a transmission band control Msg indicating a band-narrowing to a transmission side always with a minimum reach time. For this, a communication control device (100) and a radio communication device (300) include: transmission band control information generation units (109, 309) for generating transmission band control information indicating band-narrowing of a transmission band according to a packet received via a radio communication channel (10A); transmission band control information generation units (109, 309) for generating transmission band control information indicating the narrowing of the transmission band according to the packet received via other radio communication channel (10B); and transmission band control information transmission channel control units (115, 315) for selecting an optimal transmission channel for transmitting the generated transmission band control information.
