Abstract: A radio receiver apparatus that can effectively utilize GI to improve the reception quality. In this apparatus, a data extracting part extracts a data portion of a direct wave from a signal subjected to a radio reception process by a received RF part. A GI extracting part extracts, from the signal subjected to the radio reception process by the received RF part, GI having a length determined by an extracted GI length deciding part. The extracted GI is adjusted by a data position adjusting part such that its rear end coincides with the read end of the extracted data portion. A combining part combines the extracted data portion with the GI the data position of which has been adjusted. The combined signal is then supplied to a frequency axis equalizing part, which equalizes the signal distortions of the combined signal on the frequency axis.

Abstract: The present invention relates to a terminal and a base station, and to a receiving and transmitting method to be performed at the terminal and the base station, respectively. In particular, the present invention relates to power consumption reduction by providing two operation bandwidths for a terminal, one being a cell-bandwidth, a bandwidth in which the cell may operate and the other one is a bandwidth, lower than the cell-bandwidth and called power-saving bandwidth. The terminal may perform the initial cell search including reception of the system information in the cell bandwidth and perform other reception/transmission/monitoring operation(s) in the power-saving bandwidth. Accordingly, a low-cost terminal implementation is enabled, which is particularly advantageous for the machine communication terminals.

Abstract: A wireless communication apparatus and a wireless communication method wherein even when the permissible delay amount of data is small, the permissible delay thereof can be satisfied. A data type determining part determines whether the delay of transport data or control information should be allowed or not. A pilot signal insertion control part decides, based on pilot insertion interval information and allowable delay information, that a pilot signal is placed adjacently to data that is not allowed to delay. A multiplexing part multiplexes encoded and modulated transport data with the pilot signal generated by a pilot signal generating part in such a manner that realizes the placement decided by the pilot signal insertion control part.

Abstract: A wireless communication base station apparatus that allows the number of times of blind decodings at a mobile station to be reduced without increasing the overhead caused by notifying information. In this apparatus, a CCE allocation part (104) allocates allocation information allocated to a PDCCH received from modulation parts (103-1 to 103-K) to a particular one of a plurality of search spaces that is corresponding to a CCE aggregation size of the PDCCH. A placement part (108) then places the allocation information in one of downstream line resources, reserved for the PDCCH, that is corresponding to the CCE of the particular search space to which the allocation information has been allocated. A radio transmission part (111) then transmits an OFDM symbol, in which the allocation information has been placed, to the mobile station from an antenna (112).

Abstract: A terminal device is equipped with: a sequence determination unit that determines a sequence number with a different pattern than the assignment pattern for the sequence number assigned to the cell in which the host device resides; a reference signal generation unit that generates a reference signal for a sequence group corresponding to the sequence number that has been determined; and a wireless transmission unit that transmits the reference signal that has been generated to a base station. The sequence determination unit employs a configuration whereby, with the sequence number assigned to the cell in which the host device resides as a cell-specific sequence number, a dynamic offset which periodically changes over time and for which the same value is not consecutive is added to the cell-specific sequence number, thereby determining a sequence number which never overlaps with the cell-specific sequence number.

Abstract: A radio communication apparatus receives control information on one or more control channel elements (CCEs) with consecutive CCE number(s). The radio communication apparatus first-spreads a response signal with a sequence defined by a cyclic shift value that is determined among a plurality of cyclic shift values from an index of physical uplink control channel (PUCCH), which is associated with a first CCE number of the one or more CCEs, and second-spreads the first-spread response signal with an orthogonal sequence that is determined among a plurality of orthogonal sequences from the index. One of cyclic shift values used for an orthogonal sequence is determined from an index of thePUCCH, which is associated with an odd CCE number, and another one of the cyclic shift values used for the same orthogonal sequence is determined from an index of the PUCCH, which is associated with an even CCE number.
