A method for transmitting feedback information, the method comprising: Receiving, by a terminal, data over a first carrier, and receiving data over a second carrier, wherein the data over the first carrier are scheduled by a first base station, and the data over the second carrier are scheduled by a second base station; Generating, by the terminal, first uplink control information for the first carrier and/or generating, by the terminal, second uplink control information for the second carrier; and Transmitting, by the terminal, uplink control information generated by the terminal, comprising at least one of the first uplink control information and the second uplink control information, through a Physical Uplink Control Channel, PUCCH, and/or a Physical Uplink Shared Channel, PUSCH, over one uplink carrier; characterized in that wherein transmitting, by the terminal, the uplink control information through the PUCCH and/or the PUSCH over the one uplink carrier comprises: if there is a first PUSCH of the terminal, scheduled by the first base station over the one uplink carrier, then transmitting, by the terminal, the first uplink control information through the first PUSCH over the one uplink carrier; otherwise, transmitting, by the terminal, the first uplink control information through a first PUCCH using a first PUCCH resource over the one uplink carrier; and/or if there is a second PUSCH of the terminal, scheduled by the second base station over the one uplink carrier, then transmitting, by the terminal, the second uplink control information through the second PUSCH over the one uplink carrier; otherwise, transmitting, by the terminal, the second uplink control information through a second PUCCH using a second PUCCH resource over the one uplink carrier; wherein the first PUCCH resource is different from the second PUCCH resource. Receiving, by a terminal, data over a first carrier, and receiving data over a second carrier, wherein the data over the first carrier are scheduled by a first base station, and the data over the second carrier are scheduled by a second base station; Generating, by the terminal, first uplink control information for the first carrier and/or generating, by the terminal, second uplink control information for the second carrier; and Transmitting, by the terminal, uplink control information generated by the terminal, comprising at least one of the first uplink control information and the second uplink control information, through a Physical Uplink Control Channel, PUCCH, and/or a Physical Uplink Shared Channel, PUSCH, over one uplink carrier; characterized in that wherein transmitting, by the terminal, the uplink control information through the PUCCH and/or the PUSCH over the one uplink carrier comprises: if there is a first PUSCH of the terminal, scheduled by the first base station over the one uplink carrier, then transmitting, by the terminal, the first uplink control information through the first PUSCH over the one uplink carrier; otherwise, transmitting, by the terminal, the first uplink control information through a first PUCCH using a first PUCCH resource over the one uplink carrier; and/or if there is a second PUSCH of the terminal, scheduled by the second base station over the one uplink carrier, then transmitting, by the terminal, the second uplink control information through the second PUSCH over the one uplink carrier; otherwise, transmitting, by the terminal, the second uplink control information through a second PUCCH using a second PUCCH resource over the one uplink carrier; wherein the first PUCCH resource is different from the second PUCCH resource. if there is a first PUSCH of the terminal, scheduled by the first base station over the one uplink carrier, then transmitting, by the terminal, the first uplink control information through the first PUSCH over the one uplink carrier; otherwise, transmitting, by the terminal, the first uplink control information through a first PUCCH using a first PUCCH resource over the one uplink carrier; and/or if there is a second PUSCH of the terminal, scheduled by the second base station over the one uplink carrier, then transmitting, by the terminal, the second uplink control information through the second PUSCH over the one uplink carrier; otherwise, transmitting, by the terminal, the second uplink control information through a second PUCCH using a second PUCCH resource over the one uplink carrier; wherein the first PUCCH resource is different from the second PUCCH resource.
