摘要： Provided are a communication apparatus that is operated under a wireless communication environment to which a full duplex communication scheme is applied and a communication method. The communication apparatus includes a communication section that performs wireless communication and a control section that controls operation of the communication section and processing of a signal transmitted and received by the communication section. Upon receiving, through a downlink control channel from a base station, designation regarding a resource in which interference is to be measured, the control section conducts, in the designated resource, measurement of interference from another terminal. In addition, the control section further controls transmission of interference information obtained by the measurement to the base station.

摘要： [Object] To be able to utilize radio resources more efficiently in the environment where a small cell is operated.
[Solution] Provided is a communication control apparatus including: a communication unit configured to communicate with a radio communication apparatus being connected to a base station via a radio backhaul link and being connected to one or more terminals via an access link; and a control unit configured to, when a reception on the radio backhaul link and a transmission on the access link, or a reception on the access link and a transmission on the radio backhaul link are executed on an identical channel simultaneously in the radio communication apparatus, adjust a power ratio between a reception signal and a transmission signal in order to support the radio communication apparatus in removing self-interference due to a sneak of the transmission signal from the reception signal.-

摘要： Provided are signal processing apparatus, a signal processing method, and an object detection system that enable an object detection to be accurately performed. A stereo camera performs imaging by a right camera and a left camera to acquire a stereo image. A millimeter wave radar acquires a radar image in which a position of an object is detected in a radiation range of millimeter waves based on millimeter waves. Further, by communication via a communication apparatus with a target of which positional information is known, it is determined whether or not the target is reliable, and in a case where it is determined that the target is reliable, calibration processing is performed for eliminating a deviation in coordinate systems generated in the stereo image and the radar image in which the target is detected.

摘要： Random access operation is performed under a communication environment in which a plurality of communication modes having different transmission rate coexist with small overhead. A high-grade communication station spoofs information of a packet length and a rate in a decoding portion so that a value of (packet length)/(rate) corresponds to a duration where the communication is hoped to be stopped. The other station receiving the spoofed information receives the rest of the packet with the designated rate during the interval designated by the value of (packet length)/(rate). In this case, the packet length and the rate are not those of actually transmitted packet so that this packet is discarded.
