Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 11:
12. A processor-implemented communication method of a target device, the method comprising:
receiving, from a control device, a scan packet comprising information of a transmission frequency at which the scan packet is transmitted by the control device, indicative of a set reception frequency of the control device;
identifying an actual reception frequency of the target device from the information of the transmission frequency of the control device; and
sequentially transmitting, to the control device, return packets, each comprising information of the reception frequency of the target device,
wherein, in case a communication occurs between the control device and the target device without using a frequency reference of the control device, a difference occurs in the information of the reception frequency in the return packet from the set reception frequency of the control device indicated by the respective scan packet information of at least one scan packet received by the target, and
wherein, in a state where the actual reception frequency of the target device is unknown due to the difference, the information of the any one of the current transmission frequencies included in the scan packets is used to identify the actual reception frequency of the target device.
