Abstract
A method for configuring a service and a method and apparatus for rate matching in a TD-SCDMA system, this method for configuring the service includes: taking that a check bit puncturing ratio should be more than 7i+a or less than 7i−a as a newly added constraint condition, and the check bit puncturing ratios of each configured service being outside a range of [7i+a, 7i−a], the method for rate matching includes: when puncturing each path of check bits of the current data block, if a difference between a position Pk of kth reserved check bit calculated according to a method defined by the service and a previously determined position NPk−1 of k−1th reserved check bit is a positive integral multiple of 7, determining a position NPk of kth reserved check bit as Pk plus 1 or Pk minus 1, and Pk plus 1 and Pk minus 1 requiring carrying out alternately.
