Abstract: A method for classifying movements. In the method, sensor data are first received. A characteristic measured variable is then ascertained from the received sensor data, and a movement sequence is classified based on the characteristic measured variable. The sensor data are input into a mathematical model, which includes coefficient(s) and is dependent on the characteristic measured variable. The mathematical model is selected based on the movement sequence. An equation of state of a sensor data value is determined, the equation of state including the coefficient(s). The sensor data value maps a curve of the characteristic measured variable. The coefficient(s) are adjusted based on the sensor data, the coefficient being kept within a predetermined range during the adjustment. The mathematical model is adjusted on the basis of the adjusted coefficient. An item of information is output, the type of the classified movement being part of the information.

Abstract: A wireless communications system and a method for frequency multiplexing a first (LAA) OFDMA transmission and a second (Wi-Fi) OFDMA transmission on a shared radio channel spanning at least partly a common bandwidth. The system determines an unallocated frequency band available beside a first frequency band intended for a first transmission and sends a sharing request comprising information about the unallocated band. The system decides to use the unallocated band in a second frequency band in the shared channel. The system sends a legacy preamble and a first part of a Wi-Fi preamble spanning the shared channel. The first transmission is sent in the first band such that an end time point of the first part of the Wi-Fi preamble coincides with a start time point of the first transmission. Further, the system sends a second part of the Wi-Fi preamble and the second transmission in the second band.
