A method for operating an ultra-wide band (UWB) channel and a narrow band (NB) channel together are provided. The method of a second UWB device includes receiving an advertisement message providing information on a UWB channel used by the first UWB device through an NB channel, and performing at least one operation for performing UWB ranging by using the UWB channel based on the advertisement message. The UWB channel may be one of candidate UWB channels allocated for UWB communication, and the NB channel may be a sub-channel of one of the candidate UWB channels.

Method and apparatus for providing ultra wide band (UWB) communication

A first electronic device according to various embodiments of the present disclosure may: determine a location of the first electronic device via an out of band (OOB) connection; select, on the basis of information regarding the determined location, an applet within the first electronic device; and carry out, by using the selected applet, ultra-wideband (UWB) communication with a second electronic device adjacent to the determined location.

Method and apparatus for carrying out ultra-wideband communication

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.

Method and device for performing UWB ranging

Disclosed is a method for performing downlink time difference of arrival (DL-TDoA) by an ultra-wide band (UWB) device that includes selecting at least one active ranging round from a ranging block based on at least one of location information or motion information about the UWB device, transferring, to a UWB sub system, a command including information about the at least one active ranging round, and performing a DL-TDoA operation based on the information about the at least one active ranging round.

Method and device for UWB communication

Methods are provided for ultra-wideband (UWB) ranging based on contention-based multiple access. A method performed by a first UWB device includes transmitting an initiation message for initiating UWB ranging, receiving an access message from a second UWB device within a contention period, transmitting a first reply message (RM), receiving a second RM corresponding to the first RM from the second UWB device, and transmitting a final message.

Methods and devices are provided for use in a vehicle. Driving information of the vehicle is obtained. The driving information includes transmission state information of the vehicle and information for an autonomous driving function. When the transmission state information indicates a position other than drive, a size of an exposed region of a first display is controlled to be a first size. When the transmission state information indicates drive and the driving information indicates that the autonomous driving function is enabled, the exposed region of the first display is controlled to be a second size that is less than the first size. When the transmission state information indicates drive and the driving information indicates that the autonomous driving function is disabled, the exposed region of the first display is controlled to be less than the second size.

Method and device for controlling display on basis of driving context

A method for operating a first ultra-wideband (UWB) device according to an embodiment of the disclosure may include: transmitting, in a first slot within a ranging round, a ranging control message for UWB communication; receiving a first packet transmitted by a second UWB device in a second slot within the ranging round based on the ranging control message; and receiving a second packet transmitted by a third UWB device in the second slot within the ranging round based on the ranging control message.

Ultra-wideband device for transmitting/receiving multiple packets and method for operating same

Methods and devices are provided for ultra-wideband (UWB) communication. A first UWB device generates a discovery message providing information used for discovery of the first UWB device. The first UWB device broadcasts the discovery message through a narrowband (NB) discovery channel. The NB discovery channel is not associated with a UWB channel. The UWB channel is one of a plurality of candidate UWB channels allocated for the UWB communication.

Method and device for ultra-wideband communication

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.

Method and device for providing UWB service

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.

Apparatus and method for providing service related to target location based on UWB

Provided is a method, performed by an electronic device, of obtaining location information. In detail, provided is a method, performed by an electronic device, of obtaining relative location information with respect to anchor devices by wirelessly communicating with the anchor devices.

Electronic device and method, performed by electronic device, of obtaining location information

According to an embodiment disclosed in this specification, an electronic device may be configured to control a size of an exposed region of a first display based on driving information of a vehicle and to set a user interface for receiving a user input associated with content displayed on the first display to at least one of the first display or an auxiliary input interface based on a size of an exposed region. Other various embodiments as understood from the specification are also possible.
