摘要： A radio transmitting apparatus wherein even if a preamble sequence transmitted via any one of the antennas of the radio transmitting apparatus is detected, the order of the space diversity can be determined with reliability and data signals can be normally decoded. In this apparatus, a deciding unit (101) decides preamble sequences the number of which is equal to the order of the space diversity and further decides transmission block intervals the number of which is equal to or greater than the order of the space diversity. An allocating unit (102) sequentially allocates the preamble sequences, the number of which is equal to the order of the space diversity, to the respective antennas, the number of which is equal to the order of the space diversity, within the respective transmission block intervals. The allocating unit (102) allocates different ones of the preamble sequences to the respective antennas at the respective same transmission timings that are within the respective transmission block intervals.

摘要： Interference between users in an MU-MIMO system is minimized by effective precoding, without increasing an overhead of control data. In a wireless communication system in which multiplex communication is possible between multiple UE1, UE2, and BS, a channel estimation and precoding selection unit 539 in BS estimates channels from the respective UE1, UE2 to the BS, determines a precoding matrix P from a projection matrix to make the two channel response matrices orthogonal or nearly orthogonal, and feeds back the precoding matrix P to UE2, and executes precoding on only UE2 of the two. A precoding unit 524 in the UE2 employs the precoding matrix P that has been notified to perform precoding of a data stream, and sends the precoded data stream to the BS.

In a base station device (100), a scheduling unit (113) selects, as an allocation resource for a terminal to which resources are to be allocated, at most one cluster band in each of a plurality of allocatable ranges set within a system band and generates allocation resource information including information relating to the selected cluster, and an encoding unit (114), a modulation unit (115), and a transmission RF unit (116) which serve as a transmission means transmit the allocation resource information generated by the scheduling unit (113) to the terminal to which the resources are to be allocated. Among the plurality of allocatable ranges, a first allocatable range is the entire system band, while a second allocatable range is a low frequency-side band or a high frequency-side band when the system band is divided into halves.

摘要： Provided is a wireless communication apparatus by which reduction of a diversity gain can be suppressed at minimum in the case of employing a repetition technology in multicarrier communication. In the wireless communication apparatus (100), repetition sections (102-1 to 102-n) repeat each data symbol inputted from modulating sections (101-1 to 101-n) to create a plurality of identical data symbols. An allocating section (103) outputs each data symbol to a multiplexing section (105) by allocating the data symbol to a plurality of subcarriers constituting an OFDM symbol. At this time, the allocating section (103) allocates at least one of the repeated identical symbols to a subcarrier different from a subcarrier to which the symbol is allocated in an adjacent sector.
