摘要： There are provided a base station device transmitting a frame capable of performing cell search without being affected by arrangement of a pilot channel and a mobile station device performing cell search by using the frame. In the base station device (100), a frame formation unit (120) forms a frame by arranging a P-SCH sequence used for synchronization of a frame timing on some symbols of multi-carrier symbols at a predetermined position from the frame head in the frequency direction and arranging an S-SCH sequence corresponding to a base station scrambling code so that it is not overlapped on some of the multi-carrier symbols at a predetermined position from the frame head with the same symbol as the frame synchronization sequence. The frame is received by the mobile station device (200) and the S-SCH is demodulated. Thus, it is possible to directly identify the base station scrambling code without using a pilot channel.

摘要： A scalable bandwidth system wherein even if a terminal does not know the breakdowns of the services in all of the bandwidths, it can perform a correlation processing of synchronous channels (SCH). A base station repetitively transmits a synchronous channel, by unit of the shortest bandwidth (e.g., 1.25 MHz) of a plurality of bandwidths served by the system, over the whole band of the longest bandwidth (e.g., 5 MHz). The terminal calculates the correlation between a synchronous channel sequence signal of the unit of the shortest bandwidth held in advance and the repetitively transmitted synchronous channel, and determines, as a frame timing, a timing at which the maximum correlation value is obtained.

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： A technique is disclosed for preventing a mobile terminal from unnecessarily connecting to a local connection service provided by a mobile router. In a communication system, a UE 10 sends user preference information to a forwarding node 20 before the UE connects to the forwarding node, which is installed in a moving body 110 as an access point of the UE to forward information to the UE. The forwarding node determines whether information capable of being supplied to the UE is appropriate for a user of the UE based on the preference information and sends the determination result to the UE. When the UE becomes connectable to the forwarding node, the UE does not connect to the forwarding node if the information capable of being supplied is not appropriate for the user of the UE based on the determination result; else the UE connects to the forwarding node.

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.
