摘要： It is possible to provide a novel pilot transmission method which can calculate an accurate channel estimation value, a MIMO transmission device using the pilot transmission method, and a MIMO reception device which communicates with the MIMO transmission device. The MIMO transmission device (100) includes phase adjustment units (130-1, 130-2) which are controlled by a pilot transmission control unit (170) to multiply parallel pilot signals by a phase adjustment coefficient group so as to adjust the pilot signal transmission timing. The pilot transmission control unit (170) differentiates the order of the transmitting antennas in accordance with the pilot transmission timing between an even-number subcarrier group and an odd-number subcarrier group. At a reception side, a path not influenced by the inter-path interference is extracted for each of the combinations of the transmitting antennas and the subcarrier groups. A channel estimation value is calculated according to the extracted path so as to improve the channel estimation accuracy.

摘要： Provided are a base station, a terminal whereby erroneous detection of control information can be reduced to prevent the degradation of the system throughput. A PDCCH generation unit (104) forms a downstream allocation control information unit (i.e., DCI) including cyclic redundant check (CRC) bits, which have been masked or scrambled by use of ID information of a terminal (200), and further including a bit sequence (i.e., virtual CRC) known between the terminal (200) and the base station; and an allocation unit (108) and a multiplex unit (109) map the formed DCI to a resource region (i.e., R-PDCCH region) that can be used as any one of a downstream control channel region and a downstream data channel region. That is, the PDCCH generation unit (104) includes the virtual CRC into the DCI only when the DCI addressed to the terminal (200) is mapped to the R-PDCCH region.

摘要： There is provided a mobile station device capable of reducing processing of cell search. In this device, an FFT timing detection unit (603) detects a symbol timing and a frame timing detection unit (606) detects a frame timing by using the frame timing detection symbol. After a frame timing is detected, a code group detection unit (608) detects a code group and a scrambling code identification unit (610) identifies a scrambling code. That is, the frame timing detection process is separated from the code group detection process and after detecting the frame timing, a symbol timing multiplied by the code group sequence is identified so that the code group is detected only at the symbol timing.

摘要： In a user equipment (UE)(100), a handover from a macro cell base station (eNB)(200) to a CSG cell base station (HeNB)(300) is controlled based on a result of comparison between reception quality from the eNB (200) and reception quality from the HeNB (300) located in a macro cell. The UE (100) comprises: a reception quality measurement unit (104) for measuring the reception quality of the eNB (200) and the reception quality of the HeNB (300); an offsetting unit (106) for offsetting the reception quality of the HeNB (300) with an offset value that makes the reception quality of the HeNB (300) relatively higher than the reception quality of the eNB (200); and an offset value correcting unit (105) for correcting the offset value according to the reception quality of the eNB (200). A user equipment is thereby provided in which handover control can be performed with an appropriate offset value that takes into consideration interference in the uplink from the user equipment to the base station.

摘要： Provided are a base station device and a mobile station device, which can lighten a cell-search processing. The base station device (100) includes a frame constitution unit (130) for forming a frame, in which a pilot symbol multiplied by a base station scrambling code assigned to that device and a plurality of sequences contained in the corresponding sequence set is arranged in at least the head or tail, and a radio transmission unit (155) for sending the formed frame. On the receiving side of the frame, the frame timing can be detected from the position of a pilot symbol contained in that frame. Since the base station scrambling code and the sequence set containing the sequences are made to correspond to each other, candidates can be narrowed to at most the base station scrambling codes of the number of the combinations of the sequences contained in the sequence set, by detecting the sequences multiplied by the pilot symbol, so that the cell search processing can be lightened.

The mobile terminal (10) comprises: a basic communication functionality (12) for receiving offset information used for cell selection and offset correction information for correcting the offset information to increase ease of connection with a micro BS set by a user, both information being broadcasted from a macro base station; a inclination setting section (14) for accepting a setting for a priority home base station with which a user desires to preferentially establish a connection among a plurality of small cells; a offset information correction processing section (18) for correcting the offset information with the offset correction information when the priority home base station is detected; and a cell selection section (24) for performing cell selection based on reception quality with the added offset information. In this way, a user-specific inclination can separately be set for each mobile terminal and the amount of notification of information can be reduced.

摘要： There is provided a multi-carrier communication method capable of preventing lowering of a throughput of another mobile device accompanying allocation of a sub-carrier for a new mobile station device. This multi-carrier communication method can acquire reception quality information for one of the sub-carriers already allocated in an MS (150a) from a BS (100a) and for one of the sub-carriers which can be allocated in the MS (150a) from the BS (100b). According to the reception quality information, a release sub-carrier is selected from the sub-carriers already allocated and a new-allocation sub-carrier is selected from the sub-carriers which can be allocated. The new-allocation sub-carrier has a frequency different from the already-allocated sub-carriers excluding the release sub-carrier. The BS (100a) is instructed to release the selected release sub-carrier and the BS (100b) is instructed to allocate the selected new-allocation sub-carrier in the MS (150a).
