Claim Text:
1. A method for encoding acknowledgement information, comprising: receiving at least one component carrier, wherein each component carrier in the at least one component carrier comprises at least one downlink subframe; generating acknowledgement information bits corresponding to the each component carrier according to the each component carrier; ordering the acknowledgement information bits corresponding to the each component carrier according to a maximum value DAI_max of a downlink assignment index (DAI) field in downlink control information (DCI) which is received on the each component carrier and used for controlling physical downlink shared channel (PDSCH) transmission and/or indicating downlink semi-persistent scheduling (SPS) release and the number N_sps of physical downlink shared channels (PDSCHs) scheduled by semi-persistent scheduling (SPS) in the at least one downlink subframe; alternately assigning the ordered acknowledgement information bits corresponding to the each component carrier to two groups, and obtaining two groups of acknowledgement information bits; and encoding the two groups of acknowledgement information bits to obtain two groups of codeword bits, respectively, and generating, from the two groups of codeword bits obtained by the encoding, total codeword bits to be transmitted; wherein the generating acknowledgement information bits corresponding to the each component carrier comprises: generating acknowledgement information bits corresponding to a first codeword and a second codeword transmitted on each downlink subframe in the each component carrier; and mapping the acknowledgement information bits corresponding to the first codeword and the second codeword transmitted on each downlink subframe to two acknowledgement information bits d( so that when only one codeword is transmitted on at least one first downlink subframe in the each component carrier, acknowledgement information bits corresponding to the one codeword transmitted on the at least one first downlink subframe are mapped to d( and/or so that when only one codeword is transmitted on at least one second downlink subframe in the each component carrier, acknowledgement information bits corresponding to the one codeword transmitted on the at least one second downlink subframe are mapped to d(
