Patent number: 11888579Abstract: Provided are a base station device and a mobile station device, which can lighten a cell-search processing. The base station device includes a frame constitution unit for forming a frame, in which a pilot symbol multiplied by a base station scrambling code 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 for sending the formed frame. On the receiving side, 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.Type: GrantFiled: January 12, 2023Date of Patent: January 30, 2024Assignee: Panasonic Intellectual Property Corporation of AmericaInventors: Katsuyoshi Naka, Hiroki Haga, Hidenori Matsuo

Patent number: 10080150Abstract: A communication device which can reduce amount of control information, limit interference with other traffics, and prevent an increase in current consumption. In this device, a separation unit separates radio resource allocation information, specific section information and transmission parameter information from a received signal. A specific section information control unit selects a sub-carrier designated by the specific section information to allocate data to be transmitted to the own unit. A channel quality measuring unit uses a pilot signal to measure the channel quality of the selected sub-carrier. A channel quality information creating unit creates channel quality information indicating the measurement results input from the channel quality measuring unit. A multiplexing unit multiplexes the transmission signal with the channel quality information.Type: GrantFiled: June 5, 2014Date of Patent: September 18, 2018Assignee: Panasonic Intellectual Property Corporation of AmericaInventors: Masayuki Hoshino, Hiroki Haga

Patent number: 8711804Abstract: A base station, a mobile station and a retransmission control method for enabling communication to be more efficiently performed. In a communication system comprising a base station (100) and a mobile station (200), a time period required for the retransmission of a transport packet to complete is determined, and a retransmission control is performed, based on the required time period, to change the order of executing the retransmission of the transport packet and a handover. In this way, when it is estimated that the retransmission will complete soon, the retransmission is caused to complete in a handover source system, thereby avoiding waste of communication resources used in the preceding transmission and retransmission processes.Type: GrantFiled: January 19, 2006Date of Patent: April 29, 2014Assignee: Panasonic CorporationInventors: Atsushi Sumasu, Hidenori Kayama, Hiroki Haga, Masayuki Hoshino, Katsuyoshi Naka, Junya Yamazaki, Ryohei Kimura

Patent number: 8660096Abstract: 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.Type: GrantFiled: September 29, 2005Date of Patent: February 25, 2014Assignee: Panasonic CorporationInventors: Hidenori Matsuo, Katsuhiko Hiramatsu, Akihiko Nishio, Ayako Horiuchi, Hiroki Haga

Patent number: 8472412Abstract: 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.Type: GrantFiled: March 23, 2011Date of Patent: June 25, 2013Assignee: Panasonic CorporationInventors: Katsuyoshi Naka, Hiroki Haga, Hidenori Matsuo
