More specifically, the method comprises the steps of: forming an isochronous channel with a second device for transmitting the data; and transmitting the data to the second device over the isochronous channel, wherein the data is human interface device (HID) data, the data is human interface device (HID) data, and the channel for transmitting the data is determined on the basis of data characteristics including reliability and urgency.
Abstract:
Provided are a method for transmitting and receiving data in a short-range wireless communication system, and a device therefor. More particularly, the method comprises the steps of: establishing a connection associated with a first channel for transmitting and receiving first data to and from a second device; establishing a connection associated with a second channel for transmitting and receiving second data, which is different from the first data, to and from the second device; transmitting and receiving, to and from the second device, the first data on the first channel on the basis of a first time interval for transmitting and receiving the first data on the first channel; and transmitting and receiving, to and from the second device, the second data on the second channel on the basis of a second time interval for transmitting and receiving the second data on the second channel, wherein the data transmission and reception on the first channel and the data transmission and reception on the second channel are performed on the basis of the transmission and reception timing of the first data at the first time interval and the transmission and reception timing of the second data at the second time interval.
Abstract:
A method according to the present disclosure comprises determining a first synchronization value associated with a point in time at which reception of the audio data of each of a first device and a second device is completed; determining a second synchronization value for synchronizing points in time at which the audio data is output from the first device and the second device; determining a first synchronization reference time point based on the first synchronization value and the second synchronization value; performing a specific operation associated with transmitting the audio data; and transmitting, to each of the first device and the second device, the audio data on a specific channel associated with transmitting the audio data, wherein the audio data is transmitted based on the first synchronization reference time point and a second synchronization reference time point determined based on a specific time value for the specific operation.
Abstract:
In the present disclosure, a method comprising: receiving a first advertisement message for measuring a declination angle between devices; measuring each declination angle between a reference point set in the control device and positions of at least one device based on the first advertisement message, wherein the positions of the at least one device are respectively adjusted such that each declination angle satisfies a specific angle for receiving a voice signal, based on the measured respective declination angles; receiving each of a first voice signals based on the respective adjusted positions from the at least one device; and measuring a volume of the received first voice signal, respectively, wherein based on the measured volume, an audio signal output angle of the at least one device is adjusted such that an audio signal received by the control device is incident at right angles to the control device.
Abstract:
Provided in the present specification is a method by which a user device performs a handover in a wireless communication system. Particularly, the method by which a user device performs a handover comprises the steps of: connecting by Bluetooth with a first target device on the basis of first authentication information; measuring a first link state between the user device and the first target device; measuring a second link state between the user device and the second target device; determining whether to perform a handover for the second target device on the basis of the first link state and the second link state; and performing a Bluetooth connection procedure with the second target device when performance of the handover for the second target device is determined, wherein second authentication information for the Bluetooth connection procedure with the second target device is the same as the first authentication information for the Bluetooth connection with the first target device.
