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 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.

Disclosed in an embodiment of the present application are a method and device for reporting power headroom (PH) under carrier aggregation, for solving the problem of how to report PH when a terminal supports the transmission of a physical uplink control channel (PUCCH) on different uplink carriers corresponding to different carrier groups. In the present application, a terminal generates a Type 1 PH and a Type 2 PH for each of multiple PUCCH-transmitting uplink carriers requiring PH reporting, generates a Type 1 PH for each non-PUCCH-transmitting uplink carrier requiring PH reporting, and reports each generated Type 1 PH and Type 2 PH to a network side in the current uplink subframe. The present application solves the above problem.

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.

When a user equipment (UE) supports the transmission of a PUCCH on different uplink carriers corresponding to different carrier groups, an uplink carrier where the PUCCH is transmitted in a current uplink subframe is determined (S501); for each uplink carrier where the PUCCH is transmitted, based on a transmission power control (TPC) command received over at least one downlink carrier in at least one carrier group transmitting uplink control information (UCI) in the PUCCH on the uplink carrier in the current uplink subframe, the UE determines a power regulation cumulant corresponding to the PUCCH transmitted on the uplink carrier in the current uplink subframe (S502); and for each uplink carrier where the PUCCH is transmitted, according to a PUCCH power control parameter and the power regulation cumulant corresponding to the uplink carrier, the UE determines the transmission power of the PUCCH transmitted on the uplink carrier in the current uplink subframe (S503), thereby realizing the PUCCH power control.
