Provided are a wireless communication apparatus and a reference signal generating method, wherein inter-cell interference is reduced inside and outside a CoMP set. A CoMP mode setting unit () sets whether the terminal () thereof is a CoMP terminal or a Non-CoMP terminal. When the terminal () is set as a Non-CoMP terminal, the hopping pattern calculating unit () calculates a ZC sequence number to be used as the transmission timing, from among all the ZC sequence numbers that can be used within the system. When the terminal () is set as a CoMP terminal, the hopping pattern calculating unit () calculates a ZC sequence number to be used as the transmission timing, by hopping the ZC sequence numbers to be used within the CoMP set. A ZC sequence generating unit () generates a ZC sequence to be used as an SRS, using the calculated ZC sequence number.

Communication apparatus and reference signal receiving method

Provided is a radio communication base station device which can prevent lowering of use efficiency of a channel communication resource for performing a frequency diversity transmission when simultaneously performing a frequency scheduling transmission and the frequency diversity transmission in a multicarrier communication. In the device, a modulation unit () executes a modulation process on Dch data after encoded so as to generate a Dch data symbol. A modulation unit () executes a modulation process on the encoded Lch data so as to generate an Lch data symbol. An allocation unit () allocates the Dch data symbol and the Lch data symbol to respective subcarriers constituting an OFDM symbol and outputs them to a multiplexing unit (). Here, when a plurality of Dch are used for a Dch data symbol of one mobile station, the allocation unit () uses Dch of continuous channel numbers.

Receiving apparatus and method thereof

Provided is a base station capable of suppressing increase of overhead of allocation result report in frequency scheduling in multi-carrier communication and obtaining a sufficient frequency diversity effect. In the base station, encoding units (-to-) encode data (#1 to #n) to mobile stations (#1 to #n), modulation units (-to-) modulate the encoded data so as to generate a data symbol, a scheduler () performs frequency scheduling according to a CQI from each mobile station so as to uniformly allocate data to the respective mobile stations for a part of RB extracted from a plurality of RB, and an SCCH generation unit () generates control information (SCCH information) to report the allocation result in the scheduler () to the respective mobile stations.

System and method for performing resource allocation in radio communication

A base station can prevent deterioration of data channel application control accuracy due to influence of transmission power control to a control channel. In the base station, each encoding section performs encoding processing to an SCCH (Shared Control Channel) of each mobile station, each modulating section performs modulation processing to the encoded SCCH, an arranging section arranges the SCCH to each mobile station to one of a plurality of subcarriers which configure an OFDM symbol, and transmission power control section controls transmission power of the SCCH based on reception quality information reported from each mobile station. The arranging section arranges a plurality of the SCCH to be under transmission power control to one of the subcarriers so that combinations at resource blocks are the same.

Integrated circuit

Integrated circuit for performing resource allocation in radio communication

A mobile station comprises a receiver and a processor. The receiver is configured to receive, from a base station, allocation information indicating one or a plurality of allocated resource block(s) of uplink which are consecutive in a frequency domain. The processor is configured to determine, based on the allocation information, one of the resources of downlink, to which an ACK or NACK signal is distributively mapped onto a plurality of resource elements in subcarrier groups. The subcarrier resources within subcarrier group are consecutive in frequency domain and nonconsecutive in the frequency domain among subcarrier groups.
