METHOD AND APPARATUS OF CONTROLLING MAC-LAYER PROTOCOL FOR DEVICE-TO-DEVICE COMMUNICATIONS WITHOUT ID
First Claim
1. A media access control (MAC) layer protocol control apparatus, comprising:
- a target device determining unit to select primary target devices based on relative distance information regarding a relative distance between a main device and a target device for communication with the main device, and to determine a final target device based on relative distance information regarding a relative distance between the main device and each of the primary target devices;
a transmitter to transmit, to each of the primary target devices, a selection notification message and a relative distance information request message that are generated by the target device determining unit; and
a receiver to receive, from each of the primary target devices, a response message corresponding to the selection notification message, and relative distance information used to determine a final target device.

Abstract
An apparatus and method for enabling a device-to-device (D2D) communication, despite an identifier (ID) of a target device being unknown are provided. The apparatus may include a target device determining unit to select primary target devices based on relative distance information between a main device and a target device for communication with the main device, and to determine a final target device based on relative distance information between the main device and each of the primary target devices, a transmitter to transmit, to each of the primary target devices, a selection notification message and a relative distance information request message that are generated by the target device determining unit, and a receiver to receive, from each of the primary target devices, a response message corresponding to the selection notification message, and relative distance information used to determine a final target device.

8. A media access control (MAC) layer protocol control apparatus, comprising:
-
a message receiver to receive a selection notification message and a relative distance information request message from a main device; a relative distance information generator to generate relative distance information, based on the received relative distance information request message, the relative distance information being used to measure a distance from the main device to a target device; and a message transmitter to transmit the generated relative distance information, and a response message corresponding to the selection notification message. - View Dependent Claims (9)

10. A media access control (MAC) layer protocol control method, comprising:
-
selecting, by a main device, primary target devices, and transmitting a selection notification message to each of the primary target devices; transmitting, by each of the primary target devices, a response message corresponding to the selection notification message to the main device; and determining, by the main device, a final target device among the primary target devices, in response to the response message. - View Dependent Claims (11, 12, 13, 14, 15)
