Abstract
A base station determines quantities of information to be fed back by a mobile terminal using each of a first feedback channel and a second feedback channel, generates feedback control information used for determining a coding rate based on the determined quantities of information for each of the first feedback channel and the second feedback channel, and transmits, to the mobile terminal, a feedback channel allocation message containing the feedback control information and information on the first feedback channel and the second feedback channel.
Claims20
A method of allocating feedback channels by a base station in a wireless communication system, the method comprising:
- determining quantities of information to be fed back by a mobile terminal using each of a first feedback channel and a second feedback channel;
- generating feedback control information used for determining a coding rate based on the determined quantities of information for each of the first feedback channel and the second feedback channel;
- and
- transmitting, to the mobile terminal, a feedback channel allocation message including the feedback control information and information on the first feedback channel and the second feedback channel.
A method of transmitting feedback information by a mobile terminal in a wireless communication system, the method comprising:
- receiving, from a base station, a feedback channel allocation message including feedback control information and information on a first feedback channel and a second feedback channel;
- and
- transmitting feedback information to the base station by using the feedback channel allocation message,
- wherein the feedback control information is used for determining a coding rate based on quantities of information to be fed back by the mobile terminal determined using each of the first feedback channel and the second feedback channel.
A base station in a wireless communication system, the base station comprising:
- a controller configured to determine quantities of information to be fed back by a mobile terminal using each of a first feedback channel and a second feedback channel, and to generate feedback control information used for determining a coding rate based on the determined quantities of information for each of the first feedback channel and the second feedback channel;
- and
- a transmitter configured to transmit, to the mobile terminal, a feedback channel allocation message including the feedback control information and information on the first feedback channel and the second feedback channel.
A mobile terminal in a wireless communication system, the mobile terminal comprising:
- a receiver configured to receive, from a base station, a feedback channel allocation message containing feedback control information and information on a first feedback channel and a second feedback channel;
- and
- a transmitter configured to transmit feedback information to the base station by using the feedback channel allocation message,
- wherein the feedback control information is used for determining a coding rate based on quantities of information to be fed back by the mobile terminal using each of the first feedback channel and the second feedback channel.
