Claim 6:
7. A method, comprising:
receiving L pieces of first data, wherein L is an integer greater than 1;
determining reception statuses for the L pieces of first data, the determining the reception status comprising: determining that L1 pieces of first data are correctly received, wherein L1 is a positive integer less than or equal to L;
receiving second data, the receiving the second data comprising: decoding the second data by using L2 pieces of first data in the L1 pieces of first data, to obtain L3 pieces of first data that are in the L pieces of first data and that are different from the L1 pieces of first data, wherein the L2 pieces of first data are comprised in the N pieces of first data, L2 is a positive integer less than or equal to L1, L3 is a nonnegative integer less than or equal to L, and a sum of L1 and L3 is less than or equal to L, wherein the second data is data obtained after N pieces of first data are encoded, the N pieces of first data are comprised in the L pieces of first data, and N is a positive integer less than or equal to L;
generating feedback information based on the reception statuses for the L pieces of first data and the second data, wherein the feedback information indicates one or more reception statuses for M pieces of first data and comprises first feedback information or second feedback information, wherein the M pieces of first data are included in the L pieces of first data, and M is a positive integer less than or equal to L, wherein the first feedback information indicates that the L3 pieces of first data are correctly received, L3=M, wherein the second feedback information indicates that the L1+L3 pieces of first data are correctly received, L1+L3=M; and
sending the feedback information.
