Abstract: Embodiments provide methods and devices for data transmission and assignment of uplink control channel resources in an uplink FDD carrier, for enabling a recipient to provide HARQ feedback for data transmitted in the downlink using carrier aggregation of a downlink FDD carrier and at least one TDD carrier. A method includes associating each downlink subframe in the downlink FDD carrier with an uplink control channel subframe in the uplink FDD carrier, associating each downlink subframe and special subframe in the TDD carrier with an uplink control channel subframe in the uplink FDD carrier, assigning uplink control channel resources in the uplink FDD carrier to the recipient, according to the made associations, and transmitting data on said downlink FDD carrier and/or TDD carrier, to be received by the recipient.

Abstract: A information reporting method, base station and user equipment is provided in this invention. The method comprises sending the MAC layer carrier activation signaling to the UE, for activating a first CC of the UE, the MAC layer carrier activation signaling comprising CQI instruction information, for instructing the UE to report aperiodic CQI information of a second CC of the UE, so that the UE triggers to report aperiodic CQI information of the second CC of the UE upon receiving the MAC layer carrier activation signaling. With the information reporting method, base station and user equipment provided in an embodiment of this invention, the problem of slower report of CQI information of activated CCs can be addressed.

Abstract: A method, an apparatus, a UE, and a base station for transmitting a HARQ-ACK are disclosed. The method includes: determining a channel for transmitting a HARQ-ACK; determining a HARQ-ACK feedback bit; and sending the HARQ-ACK feedback bit on the channel. According to this application, transmission of a HARQ-ACK between a UE and a base station can be implemented in a scenario where carrier aggregation is performed between base stations having a non-ideal backhaul.

The transmitting method includes: calculating the number (Q′) of modulation symbols occupied by the UCI to be transmitted; dividing the information bit sequence of the UCI to be transmitted into two parts; using Reed Muller (RM) (32, 0) codes to encode each part of information bit sequence of the UCI to be transmitted to obtain a 32-bit coded bit sequence respectively, and performing rate matching so that the rate of the first 32-bit coded bit sequence is ┌Q′/2┐×Qm bits and that the rate of the second 32-bit coded bit sequence is (Q′−┌Q′/2┐)×Qm bits; and mapping the two parts of coded bit sequences that have undergone rate matching onto a Public Uplink Shared Channel (PUSCH), and transmitting the coded bit sequences to a base station.
