摘要： In a wireless communication base station device, a modulation unit carries out modulation processing for Dch data after coding to generate a Dch data symbol. A modulation unit carries out modulation processing for Lch data after coding to generate an Lch data symbol. An allocation unit allocates the Dch data symbol and Lch data symbol to each sub-carrier composing an OFDM symbol and outputs the allocated sub-carrier to a multiplex unit. In this case, the allocation unit allocates the Dch data symbol to a plurality of resource blocks where one Dch is arranged at an interval equal to integral multiples of the number of resource blocks composing a resource block group.

摘要： Wireless communication wherein channel estimation accuracy is improved while keeping the position of each bit in a frame, even when a modulation system having a large modulation multiple value is used for a data symbol. An encoding operation encodes and outputs transmitting data (bit string) and a bit converting operation converts at least one bit of a plurality of bits constituting a data symbol to be used for channel estimation, among the encoded bit strings, into ‘1’ or ‘0’. A modulating operation modulates the bit string inputted from the bit converting operation by using a single modulation mapper and a plurality of data symbols are generated.

摘要： A radio communication device capable of randomizing both inter-cell interference and intra-cell interference. In this device, a spreading section primarily spreads a response signal in a ZAC sequence set by a control unit. A spreading section secondarily spreads the primarily spread response signal in a block-wise spreading code sequence set by the control unit. The control unit controls the cyclic shift amount of the ZAC sequence used for the primary spreading in the spreading section and the block-wise spreading code sequence used for the secondary spreading in the spreading section according to a set hopping pattern. The hopping pattern set by the control unit is made up of two hierarchies. An LB-based hopping pattern different for each cell is defined in the first hierarchy in order to randomize the inter-cell interference. A hopping pattern different for each mobile station is defined in the second hierarchy to randomize the intra-cell interference.

摘要： The signaling amount in selecting a plurality of beams is reduced in pre-coding to enhance throughput. When notification of a beam number is provided in a feedback signal from a user equipment to a radio base station, a superior beam number, having a high quality rank with small time variation, is bound up and fixed for a predetermined time period and notification of only a inferior beam number is provided within the predetermined time period. For example, to select three beams among six beams, first, notification of the superior two beam numbers (beam numbers ‘b’ and ‘c’) is provided. These beam numbers are fixed for a predetermined time period and then notification of only the inferior one beam number (beam number ‘e’) is provided within the predetermined time period. Thus, the signaling amount for providing beam number notification is reduced.

摘要： 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.
