Publication number: 20240333572Abstract: Provided is a transmitter which improves the flexibility of SRS resource allocation without increasing the amount of signaling for notifying the cyclic shift amount. In the transmitter, with regard to each basic shift amount candidate group having a basic shift amount from 0 to N?1, a transmission control unit (206) specifies the actual shift amount imparted to a cyclic shift sequence used in scrambling a reference signal transmitted from each antenna port, said specification being performed based on a table in which cyclic shift amount candidates correspond to each antenna port, and based on setting information transmitted from a base station (100). With regard to basic shift amount candidates for shift amount X, the table differentiates between an offset pattern comprising offset values for cyclic shift amount candidates corresponding to each antenna port and an offset pattern corresponding to basic shift amount candidates of X+N/2.Type: ApplicationFiled: June 14, 2024Publication date: October 3, 2024Inventors: Yoshihiko OGAWA, Akihiko NISHIO, Masayuki HOSHINO, Takashi IWAI

Publication number: 20240314701Abstract: Disclosed is a wireless communication device that can suppress an increase in power consumption of a terminal while preventing the degradation of SINR measurement precision resulting from TPC errors in a base station. A terminal controls the transmission power of a second signal by adding an offset to the transmission power of a first signal; an offset-setting unit sets an offset correction value in response to a transmission time gap between a third signal transmitted the previous time and the second signal transmitted this time; and a transmission power control unit controls the transmission power of the second signal using the correction value.Type: ApplicationFiled: May 22, 2024Publication date: September 19, 2024Inventors: Takashi IWAI, Daichi IMAMURA, Akihiko NISHIO, Yoshihiko OGAWA, Shinsuke TAKAOKA

Patent number: 6738763Abstract: An information retrieval system whereby identical search results can be derived irrespective of the kind of DBMS or OS. A keyword normalizing device normalizes a keyword transmitted from a client through a network. A normalized data searching device then searches normalized data in a data storage section for data corresponding to the normalized keyword, and supplies the data to source data acquiring device. The source data acquiring device acquires source data associated with the normalized data supplied thereto, from among source data in the data storage section, and supplies the acquired source data to a sorting device. The sorting device first sorts the normalized data and then the source data in order of the sorted normalized data, and supplies the resulting source data to a source data supply device. The source data supply device transmits the source data to the client through the network.Type: GrantFiled: June 26, 2000Date of Patent: May 18, 2004Assignee: Fujitsu LimitedInventors: Hiroyuki Suzuki, Masaaki Mitani, Masayoshi Itakura, Akihiko Ogawa, Hirotoshi Fujibe
