Abstract  Abstract

The present invention provides a terminal device that allows constraints on new user allocation to be prevented and a spread code to be allocated in a scheduler even when non-adaptive HARQ control is employed using a PHICH. A codeword generator (103) generates code words (CW) by encoding a data sequence a layer mapping unit (108) places each of the CWs in one or a plurality of layers a DMRS generator (110) generates a reference signal for each layer in which a CW is placed by using any resource among a plurality of resources defined by a mutually orthogonal plurality of OCCs and an ACK/NACK demodulator (102) receives a response signal indicating a retransmission request for a CW. When a response signal requesting retransmission of only a single CW placed in a plurality of layers is received the DMRS generator (110) uses each resource that has the same OCC among the plurality of resources for the reference signals generated in the corresponding layers.
