摘要： A method for constructing a process block combination to be transmitted via at least two layers in a communication system based on at least two layers and a method for mapping the process block combination to the layers are disclosed. A process block having a first process block index is mapped to either one of the at least two layers. The number of process block indexes predetermined by an upper layer of more than a Media Access Control (MAC) layer is determined. A second process block having a second process block index corresponding to a modulo-operation result is mapped to a second layer of the at least two layers according to the determined number of process block indexes. The modulo-operation is performed between the first process block index and another index spaced apart from the first process block index by a difference of a predetermined index.
