Document Type and Number:
WIPO Patent Application WO/2013/157865
Kind Code:
A1
Abstract:
Disclosed in the present application is a method for performing hybrid automatic repeat and request (HARQ) for device-to-device communication by a first user equipment in a wireless communication system. Particularly, the method comprises the steps of: receiving scheduling information for signal transmission from an eNode B to a second user equipment; transmitting data to the specific user equipment in a first subframe according to the scheduling information; and transmitting the data or new data to the second user equipment in a third subframe according to a response signal to the data, wherein the response signal is transmitted from the second UE to the eNode B in a second subframe positioned between the first subframe and the third subframe, and an interval between the first subframe and the third subframe, which is an HARQ period for the device-to-device communication, is set as a power number of an HARQ period between the first user equipment and the eNodeB.
