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： A terminal that communicates with a base station monitors a physical downlink control channel allocated in a physical downlink control channel region and an enhanced physical downlink control channel allocated in a physical downlink shared channel region different from the physical downlink control channel region. If the physical downlink control channel is detected, the terminal reports response information via a physical uplink control channel resource corresponding to the resource in which the physical downlink control channel was detected. If the enhanced physical downlink control channel is detected, the terminal reports via a prescribed physical uplink control channel resource.

摘要： A base station is capable of efficiently notifying a terminal of control information. The base station communicates with the terminal using a sub-frame including a plurality of resource block pairs. The base station sets a second control channel region in the terminal through RRC signaling that is higher-layer control information, the second control channel region being a region set differently from a first control channel region in which a first control channel is to be arranged. The base station transmits control information for the terminal by mapping the control information to a second control channel that is to be arranged in the second control channel region. The first control channel region is set in the sub-frame to be specific to the base station, and the second control channel region is set in the sub-frame to be specific to the terminal in units of the resource block pairs.

摘要： In a radio communications system in which a base station and a terminal communicate with each other, the base station is capable of efficiently notifying the terminal of control information. The base station sets monitoring of a second control channel in the terminal through RRC signaling that is higher-layer control information, the second control channel being a control channel different from a first control channel detectable by the terminal regardless of whether the terminal is in connected state or idle state and being detectable by the terminal only in a case where the terminal is in the connected state. The base station transmits control information for the terminal by mapping the control information to the second control channel. The connected state is a state where the terminal holds information concerning a network, and the idle state is a state where the terminal does not hold information concerning a network.

摘要： A terminal device includes communication means for carrying out communication with a base station device, and generation means for generating a rank indicator specifying a preferred rank, first partial precoder information and second partial precoder information specifying a preferred precoder, and a reception quality indicator specifying a preferred transmission rate. In a first feedback mode in which reception quality information is reported periodically to the base station device, the communication means reports the second partial precoder information and the reception quality indicator at first timing, and reports the rank indicator and the first partial precoder information at second timing different from the first timing. In a second feedback mode in which the reception quality information is reported aperiodically to the base station device, the communication means reports the rank indicator, the first partial precoder information, the second partial precoder information, and the reception quality indicator at the same timing.
