Abstract: A power control method and device are used for achieving transmit power control of a User Equipment (UE) in a multi-carrier mode. The power control method includes: calculating a transmit power of a UE when the UE sends data through a plurality of carriers; and performing power compression on each carrier either step by step according to property parameters of each carrier or synchronously according to a compression ratio, when the transmit power of the UE exceeds a preset maximum transmit power. A power control device is further provided.

Abstract: A signal encoding method and device and a method for encoding a joint feedback signal are provided. When two carriers are configured with multiple-input and multiple-output (MIMO), Hybrid Automatic Repeat reQuest-ACKnowledgement (HARQ-ACK) signals of the two carriers are combined into a joint feedback signal. The joint feedback signal is mapped into a codeword according to predetermined mapping relationship between signals and codewords. Therefore, through the method for combining and encoding feedback signals of two carriers for transmission on a code channel in a dual cell (DC)-MIMO mode, 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 and apparatus for encoding feedback signal is provided. The method includes: encoding feedback signals of three carriers to output a bit sequence; and transmitting the bit sequence on a High Speed-Dedicated Physical Control Channel (HS-DPCCH). The encoding the feedback signals of the three carriers may specifically include: mapping the feedback signals of the three carriers into a codeword, in which the codeword can be selected from a codebook, and codewords in the codebook satisfy a particular code distance relationship. The method for jointly encoding feedback signals of three carriers in a Ternary Cell (TC) mode is provided. Feedback signals are transmitted over a single code channel. Therefore, power overhead is reduced, and system performance is improved.
