摘要： A control unit, in cooperation with an interface (IF) unit, a modulation unit and a baseband processing unit, produces a packet signal composed of a plurality of streams. While using as a reference a first known signal assigned to one of the plurality of streams and performing a cyclic timing shift within the first known signal on a first known signal assigned to another stream, the control unit performs a timing shift also on an extensional known signal assigned to a stream where no data is assigned. The amounts of timing shift are given degrees of priority beforehand and for the stream where data signals are assigned the control unit uses the amounts of timing shift in descending degree of priority. For the stream where no data signal is assigned, the control unit uses the amounts of timing shift also in descending degree of priority.

摘要： In response to a connection request from a terminal, a base station provides a signal indicating a reception operation adapted to a transmission operation of the base station to the terminal. Based on the indicating signal, the terminal selects and performs the optimum reception operation. The terminal also provides its own reception operation information in advance to the base station. Based on the reception operation information, the base station transmits a reception operation indication to the terminal. These processes are realized with software by DSP (12, 14) and the like.

摘要： A wireless communication terminal apparatus wherein CoMP communication can normally be performed without increasing the overhead of an upstream line control channel. In this apparatus, a spreading unit primarily spreads a response signal by use of a ZAC sequence established by a control unit. A spreading unit secondarily spreads the response signal, to which CP has been added, by use of a block-wise spread code sequence established by the control unit. The control unit controls, in accordance with sequence numbers and a hopping pattern established therein, the circular shift amount of the ZAC sequence to be used for the primary spread in the spreading unit and the block-wise spread code sequence to be used for the secondary spread in the spreading unit. The hopping pattern established in the control unit is a hopping pattern common to a plurality of base stations that CoMP-receive the response signal.

摘要： A radio unit receives burst signals in a target system or those in a MIMO system. A judgment unit determines if a MIMO signal having a form of channel corresponding to the target system is assigned posterior to a target LTS and a target signal. If a constellation of signal points in a position posterior to the target LTS and target signal corresponds to a constellation of signal points in a MIMO signal, the judgment unit judges that the MIMO signal is assigned in the received burst signal. If it is judged by the judgment unit that the MIMO signal was assigned, an instruction unit stops the operation of a baseband processing unit for MIMO-STS and the like assigned posterior to the MIMO signal.
