METHOD AND APPARATUS FOR ENCODING AND PROCESSING ACKNOWLEDGEMENT INFORMATION

摘要

A method for encoding acknowledgement information includes: receiving a component carrier, where the component carrier includes at least one downlink subframe; generating acknowledgement information bits corresponding to the component carrier according to the received component carrier; dividing the acknowledgement information bits into two groups so that each group includes at least one acknowledgement information bit, where the at least one acknowledgement information bit corresponds to physical downlink shared channel PDSCH transmission, and/or downlink control information DCI, where the DCI is used for indicating downlink semi-persistent scheduling SPS release; and encoding the two divided 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. In addition, a method for receiving acknowledgement information, an apparatus for encoding acknowledgement information, and an apparatus for processing acknowledgement information are also included.

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 or indicating downlink semi-persistent scheduling (SPS) release and the number N_sps of physical downlink shared channels (PDSCHs) scheduled by the 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 divided groups of acknowledgement information bits to obtain two groups of codeword bits, respectively, and generating a total codeword bits to be transmitted, from the two groups of codeword bits obtained by the encoding; wherein the ordering the acknowledgement information bits corresponding to the each component carrier according to the DAI_max and the N_sps comprises:
placing acknowledgement information bits into last N_sps×a bit positions, with the acknowledgement information bits corresponding to N_sps PDSCHs scheduled by semi-persistent scheduling;placing acknowledgement information bits into first DAI_max×a bit positions, with the acknowledgement information bits corresponding to downlink subframes corresponding to DCI of DAI=1 to DAI=DAI_max; andsetting the remaining (D×a−(DAI_max+N_sps)×a) acknowledgement information bits to ‘0’;wherein the a is a bit number of acknowledgement information bits corresponding to each of the downlink subframes and the D is a number of downlink subframes for which the acknowledgement information bits need to be generated.
