Abstract: A method, a user equipment and a base station are provided. The method is for transmitting Hybrid Automatic Repeat Request-Acknowledgement (HARQ-ACK) information in a communication system in which two carriers are configured, which includes: a user equipment encodes a codeword of the two carriers. The codeword represents encoded HARQ-ACK information of a first carrier and a second carrier according to a specific encoding scheme of dual-carrier configured with Multiple-Input Multiple-Output (DC-MIMO). The user equipment then transmits the encoded codeword of the two carriers to a base station. Therefore, bit error ratio (BER) and detection error cost are decreased, power overhead is saved, and a cubic metric (CM) value of the system is not affected, thereby enhancing the performance of the system.

Abstract: A method, a user equipment, and a base station device for transmitting indication information. A method comprises: initially setting an indication information feedback mode of a user equipment to a deactivation state, where the user equipment in the deactivation state does not transmit indication information to a base station; after receiving an indication information feedback request transmitted by a network side, setting the indication information feedback mode of the user equipment to an activation state, where the user equipment in the activation state uses an indication information feedback cycle to transmit the indication information to the base station. Embodiments of the present disclosure initially set a user equipment to a deactivation state of not transmitting indication information to the base station, set a user equipment to an activation state of transmitting indication information when a network side has transmitted an indication information feedback request, reducing unnecessary uplink indication information feedback.
