Abstract: The present technology relates to a reception device and method and a transmission device and method that enable provision of a low power consumption wireless communication system that can be used regardless of location. A terminal on a transmission side transmits a control frame containing transmission-related information regarding a transmission time and a transmission frequency that are determined on the basis of an internal time and a terminal ID on a transmission side. Then, after transmitting the control frame, the terminal on the transmission side transmits a data frame containing predetermined data in accordance with the transmission time and the transmission frequency. The present technology can be applied to wireless communication systems.
