摘要： In a wireless communication method, a first wireless communication apparatus transmits through a first wireless resource to a second wireless communication apparatus a first signal generated from a second signal for use in processing performed by the second wireless communication apparatus and a third signal for use in error checking of the second signal. The second wireless communication apparatus detects a second wireless resource to be used in the processing on the basis of the first signal, and performs the processing by using the second signal and the detected second wireless resource. For the detection, a section of the first signal corresponding to the second wireless resource is scrambled, or the first signal is scrambled with a scrambling sequence corresponding to the second wireless resource, or the bit order in at least part of the first signal is changed in a manner corresponding to the second wireless resource.

摘要： A method in a communication system, where a systematic code obtained by systematic encoding of information bits having dummy bits inserted and by deletion of the dummy bits from results of the systematic encoding is transmitted. On a receiving side, the deleted dummy bits are inserted into the received systematic code and then decoded. The method includes: deciding a size of dummy bits for insertion into information bits; segmenting the information bits into a number of code blocks when a bit size of the information bits is greater than a stipulated size; inserting dummy bits into each block of the segmented information bits in conformity with a dummy bit insertion pattern; performing systematic encoding of each block of the information bits into which the dummy bits are inserted, and deleting the dummy bits from the results of the systematic encoding to generate a systematic code.
