Abstract: A method for resetting the configuration for a downlink time difference of arrival is provided, including a method by an ultra-wide band (UWB) device that includes generating a UWB message for resetting a configuration for a multi-cluster and transmitting the UWB message. The UWB message may include information used to indicate that the UWB message is a configuration message for resetting the configuration for the multi-cluster.

Abstract: The present disclosure relates to a method for dynamically controlling ranging power. An electronic device method using ultra-wide band (UWB) communication, according to various embodiments of the present disclosure, comprises the steps of: transmitting an initiation message for initiating UWB ranging; and identifying whether a response message corresponding to the initiation message has been received from another electronic device. The initiation message includes ranging power control request information for dynamic power control with respect to the UWB ranging, and the response message can include ranging power control response information corresponding to the ranging power control request information.
