Patent number: 8416704Abstract: A radio communication system of a frequency hopping system, which carries out time division multiplex by TDMA and carries out communications while changing over two or more frequencies with respect to a radio link, wherein radio resources are efficiently utilized by establishing a plurality of radio links. A first communication apparatus periodically transmits control data by a frame cycle and a second communication apparatus which is a communication partner thereof receives the above-described control information during standby and secures synchronization in timing of frames and slots and timing of frequency hopping. Communication signals between both communication apparatuses and control information are overlapped in a slot to establish radio links. Once radio links are established in a plurality of slots other than a slot for transmitting control information, control is performed such that the control information is overlapped in the slots in which a radio link is established.Type: GrantFiled: December 10, 2008Date of Patent: April 9, 2013Assignee: Panasonic CorporationInventors: Toshiyuki Sugitani, Shigeki Yagi, Tetsuya Ashizuka, Yoshihiro Takehisa, Shinji Fukuda, Takatsugu Ito

Patent number: 7356104Abstract: A radio communication apparatus and method employs frequency hopping in a predetermined pattern based on a hopping carrier table. An intermittent receiving section activates a carrier frequency designating section every constant cycle to give a command for receiving the control channels of opposing radio base stations. In the case in which a hopping order in a hopping carrier table is skipped by n to carry out switching every intermittent receiving cycle in an intermittent receiving operation, an intermittent receiving cycle is set in such a manner that the n and a total number m of hopping carrier frequencies in the hopping carrier table have a prime relationship with each other. The electric field strength of a carrier frequency in a spare carrier list is measured by the intermittent receiving operation and an interference counter of a spare carrier is increased or decreased corresponding to a frequency at which the electric field strength exceeds or does not exceed a predetermined threshold.Type: GrantFiled: July 9, 2004Date of Patent: April 8, 2008Inventors: Shinji Fukuda, Yoshihiro Takehisa
