Abstract
A radio communication terminal of the present invention determines expected communication speeds used on a forward link on the basis of receiving conditions of carriers Cfw1 to Cfw3 and transmits DRC values indicating the expected communication speeds to radio base stations. When the number of reverse link carriers used for communication on a reverse link is less than the number of radio base stations, the radio communication terminal transmits the speed control values for the radio base is stations by use of a carrier Crv1.
Claims10
A radio communication terminal configured to communicate with a plurality of radio base stations by a multicarrier using a plurality of carriers, comprising:
- an expected communication speed determination unit configured to determine expected communication speed to be used on a forward link on the basis of receiving condition of the carriers;
- and
- a speed control value transmitter configured to transmit a speed control value indicating the expected communication speed determined by the expected communication speed determination unit, to the radio base stations, wherein
- when the number of reverse link carriers used for communication on a reverse link is less than the number of forward link radio base stations transmitting a forward link carrier used for communication on the forward link, the speed control value transmitter transmits the speed control value for the respective forward link radio base stations by use of any of the reverse link carriers.
A communication method for performing communication between a plurality of radio base stations and a radio communication terminal by a multicarrier using a plurality of carriers, comprising the steps of:
- determining expected communication speed to be used on a forward link on the basis of receiving condition of the respective carriers;
- and
- transmitting a speed control value indicating the determined expected communication speed to the respective radio base stations, wherein
- when the number of reverse link carriers used for communication on a reverse link is less than the number of forward link radio base stations transmitting a forward link carrier used for communication on the forward link, the speed control value for the forward link radio base stations is transmitted using any of the reverse link carriers, in the step of transmitting.
