Abstract:
Disclosed are a wireless communication base station device, a wireless communication terminal device, and a wireless communication method with which the amount of signaling is reduced while maintaining a high scheduling gain. A judgment unit (117) stores in advance a correspondence between the number of code words and the number of clusters to reduce the maximum value for the number of clusters allocated to each terminal as the number of code words increases, and thus determines the maximum value for the number of clusters based on the number of code words acquired. Based on the number of code words for a transmission signal from a terminal, an estimated value for the reception quality that is output by an estimation unit (109), and the maximum value for the number of clusters that is output by the judgment unit (117), a scheduling unit (118) schedules the allocation of the transmission signal transmitted by each terminal to a transmission band frequency (frequency resource) so as not to exceed the maximum value for the number of clusters.
Abstract:
Provided are a terminal, a base station and a signal transmission control method whereby a response signal can be efficiently transmitted when the terminal receives downstream allocation control information via an R-PDCCH. An extraction unit (204) receives downstream control information via one of a first downstream control channel, which is transmitted by use of one or more control channel elements (CCE) associated with an upstream control channel resource, and a second downstream control channel different from the first downstream control channel, and also receives data via a data channel. A control unit (208) selects, from resources associated with CCE and from particular resources reported by a base station, an upstream control channel resource to be used in transmission of the response signal, and controls the transmission of the response signal.

In a setting rule table used in setting the mapping region, PDCCH region, R-PDCCH region in slot 0, and R-PDCCSH region in slot 1 are associated with maximum size value of a downlink data size that the DCI indicates and that can be set in each resource region.
Abstract:
Provided is a terminal apparatus that can suppress the increase in interference between pilot signals in the same slot, while also suppressing the degradation of the flexibility to design cell cluster structures. When hopping information indicates an inter-slot hopping, a mapping unit (212) arranges a first pilot sequences in which a group to which the sequences used in respective slots belong varies on a slot-by-slot basis. When the hopping information indicates an inter-subframe hopping, the mapping unit (212) arranges a second pilot sequences in which a group to which the sequences used in respective slots belong varies on a subframe-by-subframe basis. The sequence group to which the sequences used in any one of the subframes in the second pilot sequences belong is identical with the sequence group to which the sequence used in any one of the slots included in that one subframe in the first pilot sequences belongs.
