  • Patent number: 9137784
    Abstract: A resource distribution method for throughput maximization in a cooperative cognitive SIMO network. The primary user sends data after receiving a cooperation confirmation message, and the cognitive network keeps silent, receives the information data of the primary user and simultaneously decodes the data. The cognitive users which successfully decode the data send the data of themselves to the cognitive base station and forward the data of the primary user; the cognitive users which cannot successfully decode the data only send the data of themselves and do not forward the data of the primary user. The cognitive base station eliminates the interference of the data of primary user and performs beamforming for the signals. According to the combined adjustment the maximum throughput performance can be realized in the cognitive network.

  • Patent number: 8989796
    Abstract: A radio communication system including a relaying apparatus and a base station, at an installment of a new base station, a parameter is autonomously adjusts a parameter to maintain a communication of the relaying apparatus. The new base station transmits a radio signal while increasing a transmission power, and the relaying apparatus, upon detecting the radio signal, transmits a signal indicating detection of the signal to an existing base station. The existing base station, upon receiving the signal indicating the detection, reduces an transmission power thereof to a minimum power to maintain a communication with a relaying apparatus and adjusts the parameter to set the transmission power to the minimum transmission power. The new base station, based on the transmission power at a time when the relaying apparatus has detected the radio signal, sets the parameter of the transmission power.
