Abstract:
1. An error detection method for control information to be transmitted by a physical channel for control information corresponding to a physical channel for data from a base station to a mobile terminal, comprising the steps of: said base station performing rate matching processing on information bits, which are data, to convert them into physical channel bits, transmitting said physical channel bits via said physical channel for data, and transmitting control information on said data via said physical channel for control information; said mobile terminal receiving said physical channel bits and said control information, and performing rate dematching processing, which is the reverse processing of said rate matching processing, on said physical channel bits using said control information; and said mobile terminal detecting an error of said received control information based on a comparison between the size of said physical channel bits determined by said control information and the size of said information bits determined by said control information, and stopping said rate dematching processing of said information bits if said error is detected; wherein said mobile terminal detects an error of said received control information if the size of said information bits determined from said control information is smaller than the size of said physical channel determined from said control information.
