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

Claim 11:
12. A method of performing device-to-device (D2D) communication by a first device, the method comprising:
obtaining at least one measurement value corresponding to a relative velocity between the first device and a second device;
adjusting at least one transmission parameter based on the at least one measurement value;
providing the adjusted at least one transmission parameter to the second device;
transmitting data to the second device based on the adjusted at least one transmission parameter;
receiving an acknowledgement corresponding to the transmitting of the data, from the second device; and
measuring an error rate based on the acknowledgement,
wherein the adjusting the at least one transmission parameter comprises:
when the error rate is less than a first threshold value, adjusting the at least one transmission parameter to correspond to a first data rate;
when the error rate is greater than a second threshold value, adjusting the at least one transmission parameter to correspond to a second data rate; and
adjusting at least one of the first threshold value and the second threshold value based on the at least one measurement value,
wherein the first data rate is greater than the second data rate.
