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.
