Abstract
Disclosed are an interleaving device and an interleaving method which shorten processing time for channel interleaving. A CQI memory writing unit (101) writes the CQI in symbol units in the row direction from the head of the memory (103) selected as a channel interleaving line. The DATA memory writing unit (102) continues from the CQI writing end address number and symbol number and writes the DATA in symbol units in the row direction of the memory (103) selected as the channel interleaving line. The memory reading unit (104) reads the stored CQI and DATA from the memory (103) according to the channel interleaving line mapping, from the head of the memory (103) in the row direction in symbol units. The data multiplexing unit (105) multiplexes RI channel interleaving data and ACK channel interleaving data with the read CQI and DATA and outputs it as channel interleaving data.
