Abstract: Disclosed are a feedback information transmitting method and device, used for addressing a lack of a plan for solving the problem of transmitting uplink control information corresponding to downlink carrier scheduled by a plurality of base stations in a dual connectivity scenario. A terminal of the present invention receives over a first carrier the data scheduled by a first base station, and receives over a second carrier the data scheduled by a second base station; generating first uplink control information for the first carrier, and/or generating second uplink control information for the second carrier; transmitting the generated uplink control information via PUCCH and/or PUSCH over an uplink carrier, the uplink control information comprising at least one of the first uplink control information and the second uplink control information. Therefore, a terminal transmitting uplink control information over only one carrier can send timely feedback of uplink control information corresponding to the downlink carrier scheduled by different base stations, ensuring that different base stations can timely acquire the feedback information corresponding to the downlink carrier scheduled by the different base stations.

Abstract: Disclosed are a response information transmission method, system and device. A base station can configure at least two PUCCH transmission carriers for user equipment, accordingly, the user equipment can select at least one PUCCH transmission carrier from the at least two PUCCH transmission carriers which are configured by the base station to transmit response information fed back on a corresponding subframe, and accordingly, the base station can receive the response information which is fed back by the user equipment on at least one PUCCH transmission carrier. The technical solution increases the number of PUCCH transmission carriers, so that compared with the manner of only configuring one PUCCH transmission carrier in the prior art, the reconfiguration operations caused by the movement of user equipment can be reduced, thereby reducing the condition that UE cannot normally communicate in the process of reconfiguration, and reducing the signaling overhead caused by the reconfiguration operation.

Abstract: Disclosed are a data transmission method and device. The method comprises: receiving a PDCCH, wherein the PDCCH comprises an indication domain which can at least indicate different HARQ processes the number of which is a sum of maximum HARQ process numbers of a plurality of carriers, and initial transmission and retransmission of data in the same HARQ process use different carriers; and receiving data scheduled by the PDCCH according to the PDCCH. By means of the present application, transmission carriers during initial transmission and retransmission of data in the same process can be adjusted flexibly, so that, when interferences to some carrier(s) are serious, data transmission in the process is adjusted to a carrier or carriers to which interference conditions are not serious, so as to improve system transmission efficiency.

Abstract: Disclosed are a method and a device for sending and receiving acknowledgement feedback information, which relate to the field of wireless communications, and are applicable to solving the problem of transmitting acknowledgement feedback information of downlink data in the case of aggregation of a time division duplex (TDD) carrier and a frequency division duplex (FDD) carrier. In this solution, a terminal receives configuration signaling sent by a network side, where the configuration signaling instructs to divide M downlink carriers for carrier aggregation into information about N downlink carrier groups, and to configure one uplink carrier for each downlink carrier group; the uplink carrier used for sending acknowledgement feedback information corresponding to downlink data is determined according to the configuration signaling, and the acknowledgement feedback information corresponding to the downlink data is sent to the network side according to a determination result after the downlink data is received. This application solves the problem of how to receive acknowledgement feedback information in the case of aggregation of the TDD carrier and the FDD carrier.
