<p>An equipment for bit collection in hybrid automatic repetition request includes upper layer control message reading module, control message after rate matching reading module, data after rate matching reading module, the first interleaving depth calculating module, the second interleaving depth calculating module, bit collection writing module and bit collection reading module. A method for bit collection in hybrid automatic repetition request, includes steps as follows: based on the control message from upper layer and the local parameter, the number of rows and that of columns in the rectangular interleaver, and, are determined; then based on the number of the systematic bits received after the HARQ second rate matching stage and, the number of temporary rows and that of temporary columns, and, are determined; according to,,,and, the systematic bits are written into the interleaver column by column, then the parity bits are written column wise into the remaining rows of the respective columns; finally, the bits are read out from the rectangular interleaver in the order different from the written order and the bit collection is completed. With the method and the equipment, the higher system throughput can be obtained.</p> |
