1. A base station apparatus, comprising:

  • a communication unit which communicates with a predetermined terminal apparatus at a variable transmission rate;

    a transmission rate varying unit which measures a quality of a channel for the predetermined terminal apparatus and performs a processing of varying a transmission rate of an uplink according to the quality, the processing involving a temporary stoppage of data communication in an uplink and downlink;

    a receiving unit which receives request signals from the predetermined terminal apparatus via the communication unit;

    a detector which detects information on whether the downlink is set to be prioritized, from signals received by the receiving unit; and

    a communication control unit which causes the transmission rate varying unit to perform the processing of varying the transmission rate of the uplink if the downlink is not set to be prioritized and causes the transmission rate varying unit to stop the processing of varying the transmission rate in the uplink and maintains the transmission rate of the uplink if the downlink is set to be prioritized, whereinprioritization of the downlink as set in the information detected by the detector is determined by the predetermined terminal apparatus.
