    Abstract: A method, performed by a first electronic device, of performing ultra-wideband (UWB)-based communication with one or more electronic devices, is provided. The method includes determining first location information associated with a target point, based on an optical sensor and gradient information of the first electronic device, determining second location information associated with a second electronic device, based on the determined first location information and a UWB signal, determining third location information indicating a location of the target point relative to the second electronic device, based on the determined first location information and the determined second location information, and transmitting the determined third location information to the second electronic device so that the second electronic device performs an operation associated with the target point.

    Abstract: A method for providing bi-directional ultra-wide band (UWB) ranging is provided. The method by a first ultra-wide band (UWB) device includes transmitting an initiation message for initiating UWB ranging, receiving at least one device access message from at least one second UWB device within a contention period, transmitting at least one reply message, receiving at least one device reply message corresponding to the at least one reply message from one or more of the at least one second UWB device, and transmitting, to the one or more second UWB device, a final message based on UWB ranging performed using the device access message, the reply message, and the device reply message.

    Abstract: A method for operating a plurality of ultra-wide band (UWB) channels by a first electronic device is provided. The method includes receiving a Bluetooth low energy (BLE) advertisement message including information about an UWB channel, from a second electronic device, identifying whether a plurality of UWB channels are operated, based on the information about the UWB channel, and identifying a UWB channel to be used for communication with the second electronic device, based on the information about the UWB channel. The information about the UWB channel may include flag information indicating an area and channel information indicating a UWB channel for the indicated area.
