    • 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.

    • The disclosed technique includes transmitting a signal intermittently according to a transmission cycle having a predetermined transmission period and a non-transmission period; receiving the signal reflected from a target with reception antennas; and detecting the target from the reflected signal. A high-frequency transmission signal attenuated during the transmission period and a receipt signal received during the non-transmission period are combined together. A correlation value between a reference transmission signal and the receipt signal in the combined signal is calculated, and the amount of phase shift in an arbitrarily selected reception antenna is calculated from the correlation value of a reference reception antenna, and the correlation values of the other reception antennas. The phase component of the correlation value of the arbitrarily selected reception antenna is corrected on the basis of the amount of phase shift.

    • A communication system has a base station control device and base station devices. The base station control device totalizes information on the number of base stations as the number of base station devices which can communicate with a mobile station device, makes Nb copies of a data frame, successively assigns integer values from 1 to Nb as stream numbers Ns to the data frames copied, and forms Nb copied data frames including Nb and Ns in header information. Copied data frames having different Ns in the header information are sent to base station devices. According to Ns and Nb, a base station device subjects the data in the copied data frame to temporal/spatial encoding to form a temporal/spatial encoding series. A mobile station device receives the temporal/spatial encoding series signal from each of the base station devices.
