Abstract
Deterioration of transmission efficiency due to a change in modulation scheme is prevented. A terminal apparatus determines a line which is to be given the priority between an uplink or downlink, according to an application activating operation from an operator, and then makes a request accordingly to a base station apparatus. The base station apparatus detects a request signal on a downlink or uplink to be prioritized. If the request signal indicates that the downlink be prioritized, the execution of a processing of changing a transmission rate of the uplink involving the stoppage of the downlink is cancelled. If the request signal indicates that the uplink be prioritized, the execution of a processing of changing a transmission rate of the downlink involving the stoppage of the uplink is cancelled.

10. 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 performs a processing of varying a transmission rate of an uplink or downlink according to a channel quality of the terminal apparatus;
a detector which detects information on a degree of priority for either the uplink or downlink from among signals received from the terminal apparatus; and
a communication control unit which maintains a transmission rate based on the detected degree of priority. - View Dependent Claims (13)

11. 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 terminal apparatus and performs a processing of varying a transmission rate of an uplink, resulting from stoppage of a downlink communication according to the quality;
a detector which detects information on a degree of priority for the downlink from among signals received from the terminal apparatus; and
a communication control unit which maintains a transmission rate of the uplink if the downlink has a higher degree of priority. - View Dependent Claims (14)

16. A terminal apparatus, comprising:
-
a communication unit which communicates with a predetermined base station apparatus at a variable transmission rate;
a decision unit which determines either an uplink or a downlink, to which priority is to be given, with the base station apparatus; and
a communication control unit which maintains a transmission rate based a degree of priority determined by said decision unit. - View Dependent Claims (17, 18, 19)

20. A method for determining a transmission rate, the method characterized in that a request signal about a degree of priority for either an uplink or a downlink is detected from a terminal apparatus to be communicated at a variable transmission rate and if the degree of priority for one of the uplink and the downlink with the terminal apparatus is higher than that for the other, a transmission rate of the other line is maintained.

21. A program executable by a computer, the program including the functions of:
-
detecting via a wireless network a request signal about a degree of priority for either an uplink or a downlink, from a terminal apparatus to be communicated at a variable transmission rate and storing it in a memory; and
maintaining a transmission rate of the uplink if the request signal stored in the memory indicates that the downlink is to be given priority or maintaining a transmission rate of the downlink if the request signal stored in the memory indicates that the uplink is to be given priority.
