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: An apparatus is disclosed for determining a gain factor of an E-DPDCH in a compressed mode. In disclosure, the E-DPDCH gain factor in the compressed mode is determined according to the number of E-DPDCHs used for initial transmission of data. With the determined E-DPDCH gain factor, the transmission power of the E-DPDCH can be accordingly determined. As the E-DPDCH gain factor in compressed mode is determined according to the number of the E-DPDCHs for initial transmission of data, the gain factor of the E-DPDCH in compressed mode can be determined accurately, and thus the transmit power of the E-DPDCH can be determined accurately according to the E-DPDCH gain factor in the compressed mode. Therefore, the waste of transmit power of the E-DPDCH is reduced, and thus the system capacity is improved.
