摘要： When transmission of a downlink signal is to be performed in sub-frame 5, at this point, no feedback of reception quality information and transmit signal pre-coding information in mode 2, which would be covered by transmit signal pre-coder confirmation, has been performed. Therefore, information on the pre-coding that has been applied to all assigned resources is transmitted by being added to a downlink control signal (353). In sub-frame 9, a downlink signal is transmitted, and transmit signal pre-coder confirmation is added thereto. With respect to this case, the mobile station apparatus determines that the downlink signal has been pre-coded using the transmit signal pre-coding information transmitted in sub-frame 8, and demodulates the received signal with it. Sub-frame 12 represents a case where downlink data is transmitted by assigning sub-band 7. In so doing, it is preferable that the base station apparatus use the reception quality information and transmit signal pre-coding information for sub-band 7 reported in sub-frame 10. Accordingly, the base station apparatus transmits to the mobile station apparatus the transmit signal pre-coding information obtained in sub-frame 10 by explicitly including it in downlink control information (358). Thus, in cases where there exist a plurality of modes for transmitting transmit signal pre-coding information, it is possible to solve the problem where information whose priority should be high is readily overwritten by information of low priority.

摘要： In case that an uplink grand from a base station apparatus is detected on PDCCH, a data designated by the uplink grant, channel state information measured at the time of transmission are transmitted by PUSCH as an uplink transmission signal. Then, in case that a notice that indicates retransmission is received, the data to be retransmission and the channel state information measured at the time of retransmission are transmitted by PUSCH. Accordingly, the mobile station apparatus can transmit appropriate channel state information when designated to retransmission so that the base station apparatus can make an efficient communication control (scheduling) between the base station apparatus and the mobile station apparatus that is suitable for the current channel condition.

摘要： The amount of control information is reduced for specifying the transmission method for simultaneously transmitting uplink data and reception quality information, and uplink data and ACK/NACK. Delay in changing the transmission method is reduced, and the mapping of uplink data and reception quality information and of uplink data and ACK/NACK is realized, in compliance with modulation scheme and coding rate of the uplink data specified by the base station apparatus. In a mobile communication system the base station apparatus allocates, to the mobile station apparatus, resources wherein the base station apparatus transmits, to the mobile station apparatus, control information for specifying a transmission format for the mobile station apparatus to transmit information using the uplink, while the mobile station apparatus simultaneously transmits, to the base station apparatus, uplink data and reception quality information based on the specified transmission format when the control information from the base station apparatus is received.
