  • Patent number: 10447320
    Abstract: An object is to mitigate interference by using effective knowledge or information as to an interference signal while reducing an increase in the amount of calculation. A terminal device includes a reception unit that receives downlink control information from a base station apparatus. In a case of a prescribed transmission mode, a downlink shared channel destined for the terminal apparatus is demodulated on the basis of a power offset between transmit power of the terminal apparatus and transmit power of another terminal apparatus in the downlink shared channel included in the downlink control information. Whether or not to perform interference cancellation is determined according to a value of the power offset.

  • Patent number: 10447343
    Abstract: In a system for controlling a radio base station, an out-of-band emergency channel based on a power cable is established between a BBU and an RRU such that even if a unique communications interface CPRI between the BBU and the RRU is abnormal, the BBU can still effectively control the RRU using the out-of-band emergency channel. In another system for controlling a radio base station, out-of-band emergency channels based on power cables are established among multiple RRUs such that even if a unique communications interface CPRI between a BBU and a target RRU is abnormal, the BBU can still effectively control the target RRU using an out-of-band emergency channel between any RRU (a unique communications interface CPRI of the RRU is normal) and the target RRU. In the present disclosure, the BBU can effectively control the RRU.

  • Patent number: 10432329
    Abstract: A transmitter includes a transmitter control section, which generates transmission data to be transmitted to a receiver. The transmission data contains variable data and verification data. The verification data is data for causing a verifying section of the receiver to verify an ID code registered in the transmitter against an ID code registered in the receiver. The transmitter control section is capable of switching between a first state and a second state. The first state is a state in which fixed data representing identification information is transmitted as the verification data. The second state is a state in which computation data computed from the variable data and the fixed data is transmitted as the verification data.
