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.
