Abstract: The present invention adopts a configuration such that when cooperative reception by a plurality of base stations is not applied, a reference signal sequence determined from a selection baseline value corresponding to the number of a sequence group allocated to a cell belonging to the device in question is selected from among a plurality of selection baseline values as a reference signal sequence for non-cooperative reception, whereas when cooperative reception by a plurality of base stations is applied, a reference signal sequence determined from one or more intermediate selection baseline values set between two adjacent selection baseline values corresponding to the number of a sequence group allocated individually to a terminal device is selected among the plurality of selection baseline values as a reference signal sequence for cooperative reception differing from the reference signal sequence for non-cooperative reception.

Abstract: A transmitting device includes a controller and a transmitter. The controller, in operation, adds an offset to a transmission power or a transmission power density of first data mapped in a remaining resource other than a data resource, to control a transmission power or a transmission power density of second data mapped in the data resource, for use of a second mapping pattern. A part of a resource on which a reference signal is to be mapped in a first mapping pattern of the reference signal is replaced with the data resource in a second mapping pattern of the reference signal. The transmitter, in operation, transmits a signal including the first data, the second data, and the reference signal.

Abstract: A base station apparatus is disclosed in which control section (150) generates an index indicating a response signal resource to be used for transmission of a response signal in response to downlink data of a plurality of CCs for at least each second CC, and transmitting section (160) transmits control information including the index. When a terminal receives the control information using only one second CC or two or more CCs among the plurality of CCs, the terminal apparatus determines the response signal resource based on the index of the second CC. Control section (150) specifies, as the response signal resource, using the index of the second CC, a first resource for transmission of a response signal in response to downlink data transmitted using only one CC or a second resource for transmission of a plurality of response signals in response to downlink data transmitted using a plurality of CCs.

Abstract: A communication apparatus includes a circuitry and a transmitter. In operation, the circuitry generates a Demodulation Reference Signal (DMRS) and generates downlink control information indicating a mapping pattern of the DMRS from a plurality of mapping patterns, and the transmitter transmits the DMRS and the downlink control information. The plurality of mapping patterns includes a first mapping pattern and a second mapping pattern. Resource elements used for the DMRS of the second mapping pattern are same as a part of resource elements used for the DMRS of the first mapping pattern. A number of the resource elements used for the DMRS of the first mapping pattern is larger than a number of the resource elements used for the DMRS of the second mapping pattern.
