Method and apparatus for direct communications in a wireless communication system

摘要

The present invention relates to a method and apparatus for direction communications in a wireless communication system. In the direct communication support method of a wireless communication system, according to one embodiment of the present invention, when a base station receives a direct communication request message from a first terminal to request a direct communication with a second terminal without going through the base station, the base station then allocates resources to be used for the direct communication and transmits resource allocation information to the first and second terminals.

主权项

1. In a 1st terminal of a wireless communication system, a direct communication method comprising:
transmitting a direct communication request message to a base station to request a direct communication with a 2nd terminal without going through the base station; receiving resource allocation information on a resource allocated to the direct communication from the base station; and generating, using the resource allocation information, a control signal and a downlink signal structure for direct communication with the 2nd terminal, wherein the control signal for the downlink signal structure is set to sustain according to an available period of the resource allocated to the 1st terminal, and wherein the downlink signal structure is exactly aligned with downlink signal timing detected by the 1st terminal.
