METHOD FOR PERFORMING HARQ FOR DEVICE-TO-DEVICE COMMUNICATION IN WIRELESS COMMUNICATION SYSTEM AND DEVICE FOR SAME

摘要

Disclosed in the present application is a method for performing HARQ for device-to-device communication by a first user equipment in a wireless communication system. Particularly, the method comprises: 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.

1. As a method of a first user equipment for performing HARQ (Hybrid Automatic Repeat and reQuest) for device-to-device communication in a wireless communication system, the method comprises:
receiving scheduling information for performing signal transmission to a second user equipment from a base station; transmitting data on a first subframe to the specific user equipment in accordance with the scheduling information; and transmitting the data or new data on a third subframe to the second user equipment in accordance with a response signal respective to the data, wherein the response signal is transmitted by the second user equipment to the base station on a second subframe being located between the first subframe and the third subframe, and wherein an interval between the first subframe and the third subframe, the interval corresponding to an HARQ cycle period of the device-to-device communication, is set to be equal to a multiple of an HARQ cycle period between the first user equipment and the base station.
