摘要： PROBLEM TO BE SOLVED: To detect symbol timing in cell searching and determine the service frequency band of a base station, at the same time, in a radio terminal equipment used in a scalable bandwidth system.
SOLUTION: A radio receiver 101 applies a radio reception process to each of all frequency bands that a base station device presents. A CP correlator 102 generates a correlation value profile with respect to the reception signal applied with a radio reception process. A correlation presence determining part 103 discriminates presence of correlation, based on the result of correlation value profile for each frequency band. A frequency band determining part 104 discriminates the service frequency band of the base station, by comparing the determining result for presence of correlation with a service frequency band determining table that has been incorporated, in advance.

摘要： PROBLEM TO BE SOLVED: To provide a base station apparatus and a mobile station apparatus capable of alleviating cell search processing. SOLUTION: The base station apparatus 100 is provided with: a frame configuration section 130 that forms a frame at least at either of the head and the end of which a pilot symbol is arranged, the pilot symbol resulting from multiplying a plurality of sequences included in a sequence set corresponding to a code group to which a base station scrambling code assigned to its own apparatus belongs; and a wireless transmission section 155 for transmitting the formed frame. Since the receiver side of the frame can detect frame timing on the basis of a position of the pilot symbol included in the frame and the base station scrambling code corresponds to the sequence set including the sequences and since objects are limited to the base station scrambling codes whose number is equal to combinations of the sequences included in the sequence set at most by detecting the sequences multiplied with the pilot symbol, the cell search processing can be alleviated.

摘要： PROBLEM TO BE SOLVED: To improve reception quality of transmission data in a mobile station by preventing interference between a system for synchronization and the transmission data.
SOLUTION: In a base station device 100, a frame forming section 120 arranges transmission data and a system to be used for identifying a frame timing and a code group to which a base station scrambling code belongs in a receiver side so that they may not be overlapped in the same symbol to be specified by a sub-carrier and a time, and forms a frame, and an RF transmission section 150 transmits the frame. In a mobile station device 200, an RF receiving section 210 receives the frame from the base station device 100, an SCH correlation value calculating section 240 multiplies the frame by all the candidates of the system one by one to take correlation, and a frame timing/code group detecting section 250 detects the frame timing and the code group on the basis of the correlation value obtained from the SCH correlation value calculating section 240.

摘要： PROBLEM TO BE SOLVED: To provide a base station apparatus, a mobile station apparatus, and a frame transmission method capable of achieving high speed cell searching by reducing a time required for the cell searching. SOLUTION: A base station 100 forms a frame arranged with a group pilot symbol comprising a pilot signal and a code group sequence for identifying a group of a base station scrambling code, forms a modified scrambling code from the base station scrambling code on the basis of a modified parameter corresponding to the number of the base station scrambling code, multiplies the modified scrambling code with the frame formed in this way, and transmits a frame multiplied with the modified scrambling code. Then a mobile station 200 uses a formed modified scrambling code replica to detect the modified scrambling code, and applies success/failure discrimination to the cell searching on the basis of the result of the detection.

摘要： PROBLEM TO BE SOLVED: To improve precision of a cell search by putting together correlation arithmetic results by streams even when the number of transmitting antennas of a base station device in a radio communication system is different.
SOLUTION: A spatial multiplexing section 103 spatially multiplexes data symbol trains to generate four streams corresponding to four transmitting antennas, and outputs the respective streams to pilot insertion sections 105-1 to 105-4. A phase rotation quantity indication section 104 indicates a phase rotation quantity, corresponding to the number of the transmitting antennas, to be added between a pilot symbol at the head of a frame and a pilot symbol at the tail. The pilot insertion sections 105-1 to 105-4 add phase differences between pilot symbols inserted into the head and tail of the frame by the phase rotation quantity indicated by the phase rotation quantity indication section 104.

摘要： PROBLEM TO BE SOLVED: To reduce inter-cell interferences between SCHs (synchronization channels) of multicarrier communication while preventing an operation quantity from increasing. SOLUTION: An SCH correlation value calculation section 204 calculates time-directional correlation values of a received data signals and a replica of a symbol series of an SHC as to all subcarriers. An SCH subcarrier detection section 205 detects the subcarrier to which the SCH is allocated based upon the calculated correlation values of the respective subcarriers. A code group detection section 207 internally holds a table in which code group numbers and subcarriers are made to correspond to one another, which is common with a base station device 100. Then the corresponding code group is identified from information regarding the subcarrier which is output from the SCH subcarrier detection section 205. COPYRIGHT: (C)2007,JPO&INPIT
