摘要： 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 allocates allocation information allocated to a PDCCH received from modulation parts to a particular one of a plurality of search spaces that is corresponding to a CCE aggregation size of the PDCCH. A placement part 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 then transmits an OFDM symbol, in which the allocation information has been placed, to the mobile station from an antenna.

摘要： Provided is a radio communication device which can make Acknowledgement (ACK) reception quality and Negative Acknowledgement (NACK) reception quality to be equal to each other. The device includes: a scrambling unit (214) which multiplies a response signal after modulated, by a scrambling code “1” or “e−j(π/2)” so as to rotate a constellation for each of response signals on a cyclic shift axis; a spread unit (215) which performs a primary spread of the response signal by using a Zero Auto Correlation (ZAC) sequence set by a control unit (209); and a spread unit (218) which performs a secondary spread of the response signal after subjected to the primary spread, by using a block-wise spread code sequence set by the control unit (209).

摘要： Provided is a base station that enables data communications in a small cell to continue even if a handover between macro cells occurs. In the base station (100), a handover determination unit (105) determines whether the handover of a control plane from the base station (100) to another macro cell is necessary for a terminal. If it is determined that the handover is necessary, a radio resource control unit (109) and a slave radio resource control unit (110) continue the control of a user plane communication process when the terminal is located inside a small cell, and the radio resource control unit (109) and slave radio resource control unit (110) stop the control of the user plane communication process and perform a process of handover to the other macro cell when the terminal is located outside the small cell.

摘要： In order to shorten the time in which an initial connection is established when switching directivity and then performing the initial connection, a frame timing control unit sets, until detection of an RACH signal, a transmission timing of a transmission frame for transmitting a search signal and a broadcast signal and also sets a reception-start timing for starting the reception of the corresponding RACH signal. A search/broadcast signal generation unit generates the broadcast signal and the search signal including reception-timing information. A beam directivity control unit sets, for a predetermined time starting from the reception-start timing, a directivity pattern such that the directivity is in the same direction as the directivity pattern for the corresponding transmission-timing information, whereby the beam directivity control unit controls a beam directivity operation unit.

摘要： A base station communicates with a terminal, for which an uplink component carrier and downlink component carriers are configured. The base station adjusts a payload size of control information, transmitted in a downlink control channel, based on a basic payload size, and maps the control information onto a search space in at least one of the downlink component carriers. The basic payload size of the control information mapped onto a search space in a primary downlink component carrier is based on a number of information bits obtained from a bandwidth of the primary downlink component carrier, and on a number of information bits obtained from a bandwidth of the uplink component carrier. The basic payload size of the control information mapped onto a search space in a non-primary downlink component carrier is based on a number of information bits obtained from a bandwidth of the non-primary downlink component carrier.
