Abstract
An apparatus and method is provided for controlling data transmission considering congestion in a wired transmission section in a wireless communication system. To this end, a reception device reports, to a transmission device, status information about a congestion status and flag information indicating occurrence of a new congestion status or maintenance of an existing congestion statue. The transmission device reduces throughput of data being transmitted through the wired transmission section, if it is determined from the flag information reported by the reception device that a new congestion status has occurred or the existing congestion status has been being maintained for a predetermined time. The transmission device requests the reception device to report a congestion status, if the congestion status is not released until a lapse of a predetermined time after occurrence of a new congestion status.
