Abstract: One example method includes transmitting a test signal through the transmit channel n, where the test signal is radiated by a service antenna element n corresponding to the transmit channel n and is received by a calibration antenna element in the phased array antenna. N coupling signals received by N calibration antenna elements coupled to the service antenna element n can then be obtained. Delay weighting can then be performed on the N coupling signals based on relative positions of the service antenna element n and each of the N calibration antenna elements to obtain N calibration signals. The N calibration signals can then be combined into the calibration signal corresponding to the transmit channel n. Calibration signals corresponding to all transmit channels in the phased array antenna can then be obtained. At least one of amplitudes or phases of the transmit channels can then be compensated for.

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.
