Abstract

A DRC signal detecting section 113 demodulates a signal outputted from a despreading section 112 and detects a DRC signal; a transmitted-ratio calculating section 101 calculates the ratio of an amount of transmitted data to the total amount of data; an assigning section 102 decides the assignment of communication resources to each communication terminal based on the DRC signal which is detected by DRC signal detecting section 113 and the transmitted-ratio which is calculated by transmitted-ratio calculating section 101.

Claims

1. A base station apparatus comprising:

an assigner that performs scheduling of assignment of a plurality of time slots in a frame to a plurality of communication terminals; and

a calculator that calculates a ratio of an amount of transmitted data to a total amount of data, for each of the plurality of communication terminals, wherein;

the assigner gives a higher priority in the scheduling to a communication terminal having a greater ratio.

2. The base station apparatus of claim 1, further comprising:

a counter that counts the number of retransmissions of data, for each of the plurality of communication terminals, wherein;

the assigner further gives a lower priority in the scheduling to a communication terminal having a greater number of retransmissions.

3. The base station apparatus of claim 1, further comprising:

a time measurer that measures a communication continuation time, for each of the plurality of communication terminals, wherein;

the assigner gives a higher priority in the scheduling to a communication terminal having a greater communication continuation time.

4. A radio communication method, comprising:

performing scheduling of assignment of a plurality of time slots in a frame to a plurality of communication terminals, and

giving a communication terminal having a greater ratio of an amount of transmitted data to a total amount of data a higher priority in the scheduling.
