Abstract
The present invention provides a base station apparatus, a mobile terminal apparatus and a communication control method that can adequately allocate resources of response signals for retransmission for spatially-multiplexed signals respectively corresponding to a plurality of layers via the uplink and that support next-generation mobile communication systems. Discloses is a configuration to receive signals in which a plurality of layers are spatially-multiplexed on the uplink from a mobile terminal apparatus (), generate HARQ ACK/NACK for signals received in the layers on the uplink, and allocate HARQ ACK/NACK for transport blocks associated with the layers, to PHICH resources, using the offset values that are fixedly defined in advance with the mobile terminal apparatus () for every uplink layer.
