## Abstract

The present invention relates to a wireless communication system. More specifically, the present invention relates to a method for carrying out HARQ action from a terminal operating in one of a plurality of link types, and to an apparatus for same, the method comprising the steps of: a first subframe (SF) receiving scheduling information; a second SF receiving data according to the scheduling information; and a third SF transmitting response information with respect to the data, wherein the first SF, the second SF, and the third SE correspond to a single HARQ process, a SF set which corresponds to the single HARQ process in a first link type comprises a plurality of SF subsets, and wherein each of the SF subsets corresponds to a single HARQ process in a second link type.

## Claims

### Claim 1

A method for a first user equipment (UE) to perform UE-to-UE communication in a wireless communication system, the method comprising:
