Abstract

One embodiment of the present invention relates to a method for UE receiving data in a wireless communication system, the method for receiving data comprising the steps of: receiving control information through a channel through which the control information is delivered; and confirming an information bit which is included in the control information and is related to reserving a resource, wherein the information bit simultaneously indicates whether UE which has transmitted the control information reserves the resource, and if the resource is reserved by the UE, the location of the resource.

Claims

1. A method of receiving or transmitting data, by a first user equipment (UE) in a vehicle-to-everything (V2X) wireless communication system, comprising the steps of:

receiving, by the first UE from a second UE, control information through a control channel; and

receiving or transmitting, by the first UE, a first data based on a first frequency resource in a subframe N indicated by the control information,

wherein the control information includes information bits indicating both an interval (I) and whether the second UE keeps the frequency resource, and

wherein the first UE receives a second data from the second UE on the frequency resource in a subframe N+I, when the information bits indicates second UE keeps the frequency resource and the first data indicated by the control information is for the first UE.

2. The method of claim 1, wherein the information bit corresponds to 0, when the second UE does not keep the frequency resource.

3. The method of claim 1, wherein a resource for the control information and a resource for a data corresponding to the control information are always selected at the same time.

4. The method of claim 3, wherein the control information and data corresponding to the control information are transmitted in a manner of being frequency division multiplexing (FDM).

5. A user equipment (UE) for receiving or transmitting data in a vehicle-to-everything (V2X) wireless communication system, the UE comprising:

a transceiver; and

a processor operatively connected to the transceiver and configured to;

receive, from a second UE, control information through a control channel; and

receive or transmit a first data based on a first frequency resource in a subframe N indicated by the control information,

wherein the control information includes information bits indicating both an interval (I) and whether the second UE keeps the frequency resource, and

wherein the UE receives a second data from the second UE on the frequency resource in a subframe N+I, when the information bits indicates the second UE keeps the frequency resource and the first data indicated by the control information is for the first UE.
