Abstract: Embodiments of the present invention provide a method, where a UE determines that uplink control information to be sent to an eNB in an uplink subframe includes channel state information (CSI) and a scheduling request (SR). The UE further determines a first uplink channel resource for sending the CSI and the SR to the eNB. The first uplink channel resource has an SR sending format and is used to send the CSI. The UE then sends the CSI and the SR to the eNB on the first uplink channel resource in the uplink subframe.

Abstract: A terminal receives downlink scheduling information of a downlink subframe F(i,j), where a set M of preconfigured downlink subframes in which the downlink subframe F(i,j) is located is divided into N subsets of preconfigured downlink subframes, a bit quantity of a hybrid automatic repeat request-acknowledgement HARQ-ACK that needs to be fed back for each downlink subframe in one subset of preconfigured downlink subframes is a predetermined value, and bit quantities of HARQ-ACKs that need to be fed back for any downlink subframes in different subsets of preconfigured downlink subframes are different. The terminal generates a HARQ-ACK codebook according to a receiving status of downlink data. And the terminal generates uplink control information after encoding the HARQ-ACK codebook; and a sending module sends the uplink control information.

Abstract: A method for transmitting and receiving Uplink Control Information (UCI), a terminal, and a base station are provided. 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 ┌Q′/2┐×Qm bits and that the rate of the second 32-bit boded 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.
