摘要： A base-station apparatus (101) and a terminal apparatus (102) communicate with each other in a communication system. When reporting reception quality information together with data to the base-station apparatus via a channel for use in data transmission, the terminal apparatus reports the reception quality information using a spatial multiplexing method identical to a spatial multiplexing method of the data if the reception quality information is reception quality information that is to be nonoperiodically reported, and reports the reception quality information using a spatial multiplexing method independent of the spatial multiplexing method of the data if the reception quality information is reception quality information that is to be periodically reported. When extracting the reception quality information reported together with the data from the terminal apparatus, the base-station apparatus extracts the reception quality information based on the assumption that the spatial multiplexing method of the reception quality information is identical to the spatial multiplexing method of the data if the reception quality information is nonoperiodically reported, and extracts the reception quality information based on the assumption that the spatial multiplexing method of the reception quality information is independent of the spatial multiplexing method of the data if the reception quality information is periodically reported.

摘要： In a radio communication system using OCC for DMRS, a base station apparatus correctly receives PUSCH. If a first mode is set in which a demodulation reference signal of a physical uplink shared channel is multiplied by an orthogonal code determined in advance or if a temporary C-RNTI was used for a transmission of downlink control information, the demodulation reference signal of the physical uplink shared channel is multiplied by the orthogonal code determined in advance, and if a second mode is set in which the demodulation reference signal of the physical uplink shared channel is multiplied by an orthogonal code determined on the basis of cyclic shift information in the downlink control information and moreover, if an RNTI other than the temporary C-RNTI was used for the transmission of the downlink control information, the demodulation reference signal of the physical uplink shared channel is multiplied by the orthogonal code determined on the basis of the cyclic shift information in the downlink control information.

摘要： In a mobile station device capable of transmitting up to a predetermined number of transport blocks to a base station device on a single physical uplink shared channel, an object is to efficiently perform HARQ in case that the mobile station device receives an uplink grant that disables a part of uplink data. The mobile station device receives downlink control information transmitted by the base station device and used for scheduling the physical uplink shared channel. In case that the downlink control information indicates that a specific transport block is disabled, the mobile station device sets ACK for a HARQ process corresponding to the specific transport block.
