Abstract  Abstract

A terminal apparatus capable of avoiding a restriction on a new user assignment and allocating a spreading code in a scheduler even when non-adaptive HARQ control is applied using PHICH. The codeword generation unit 103 generates a codeword CW by encoding a data string and the layer mapping unit 108 arranges each CW in one or a plurality of layers. The ACK / NACK demodulation unit 102 generates a reference signal for each layer on which CWs are arranged by using any of a plurality of resources defined by a plurality of orthogonal OCCs, and the ACK / NACK demodulation unit 102 indicates a retransmission request for CW And receives a response signal. When a response signal requesting retransmission of only a single CW arranged in a plurality of layers is received, the DMRS generator 110 divides resources having the same OCC among a plurality of resources into reference signals generated respectively in a plurality of layers .
