摘要： A wireless communication apparatus and a response control method wherein in a case of applying Persistent Allocation (PA) to MU-MIMO, the increase in the resources to be used in the feedback can be precluded. In a terminal, a response control unit causes, based on the type of downstream allocation control information, on an error detection result obtained by an error detecting unit and on a response rule table, a response signal to be transmitted by use of an upstream response resource designated in the downstream allocation control information. In the response rule table used in reception of a notification of MU-MIMO reallocation, respective different types of response signals are associated with a first case where there are no errors in the received downstream data of the designated resource designated in the downstream allocation control information received before that notification, a second case where the notification of MU-MIMO reallocation is successfully received and further there are no errors in the received downstream data of the designated resource, and a third case where the notification of MU-MIMO reallocation is not successfully received and further there are any errors in the received downstream data of the designated resource.

摘要： To lessen a disparity in stream mapping of transmission data when modulation data are mapped into a plurality of streams and when the plurality of streams are transmitted and received. In a wireless communication device, a stream mapper (14) that performs mapping into a plurality of streams sequentially maps a modulation symbol sequence output from a modulator (13) into a plurality of streams for each block output from a channel interleaver (12) that performs channel interleaving, such as sub-block interleaving. On this occasion, a stream mapping method is changed in predetermined unit commensurate with a block size; for instance, at each position of a sub-block length where sub-block interleaving is performed or at each position of a half sub-block length.
