摘要： Provided is a wireless communication base station device that can avert PHICH collisions between mobile stations when using a frequency hopping retransmission method in combination with a PHICH grouping method. A base station (100) is used in a wireless transmission system in which uplink data is allocated to multiple resource blocks, each M consecutive resource blocks form a block (M being an integer greater than 1), and each N consecutive resource blocks form a group (N being an integral multiple of M). A demultiplexer (115) follows a hopping pattern which changes the frequency for each block of multiple resource blocks, and extracts from the resource blocks uplink data for each of multiple mobile stations. Also, a mapping unit (103) maps PHICHs, to which response signals for uplink data for each mobile station are allocated, to downlink resources in accordance with associations between groups and PHICHs.
