ELECTRONIC DEVICE AND COMMUNICATIONS METHOD THEREOF
First Claim
1. A communication method for electronic devices, comprising:
- determining whether a transmission line is occupied or unoccupied;
based on a determination that the transmission line is unoccupied;
transmitting transmission data via the transmission line;
receiving return data that returns via the transmission line after the transmission data has been transmitted; and
determining whether data collision exists on the transmission line by comparing the transmission data with the return data, andbased on a determination that the transmission line is occupied;
waiting for a predetermined first time interval to elapse; and
after the predetermined first time interval has elapsed, returning to the determining whether the transmission line is occupied or unoccupied.

6. An electronic device comprising:
-
a communication unit configured to conduct data communication via a transmission line by transmitting or receiving data to and from another electronic device; and a control unit configured to control the communication unit by; determining whether the transmission line is occupied or unoccupied; based on the determination that the transmission line is unoccupied; transmitting, by the communication unit, transmission data via the transmission line; receiving, by the communication unit, return data that returns via the transmission line after the transmission data has been transmitted; and determining whether data collision exists on the transmission line by comparing the transmission data with the return data. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14)
