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 signal, by a user equipment (UE) in a vehicle-to-everything (V2X) communication, comprising:

receiving, by the UE, a control information including information bits related to a resource reservation; and

receiving, by the UE, first data via a first resource based on the control information,

wherein the UE receives a second data via a second resource after an interval from the first resource, based on that the information bits are non-all zero,

wherein the interval is a value determined by the information bits of non-all zero.

2. The method of claim 1, wherein the second resource is avoided by other UE which receives the control information, based on that the information bits are non-all zero.

3. The method of claim 1, wherein the second resource is selected by other UE which receives the control information, based on that the information bits are all zero.

4. The method of claim 1, wherein the UE does not receive the second data, based on that the information bits are all zero.

5. A user equipment (UE) in a vehicle-to-everything (V2X) communication, the UE comprising:

a memory; and

a processor coupled to the memory,

wherein the processor configured to receive a control information including information bits related to a resource reservation, and to receive first data via a first resource based on the control information,

wherein the UE receives a second data via a second resource after an interval from the first resource, based on that the information bits are non-all zero,

wherein the interval is a value determined by the information bits of non-all zero.

6. The UE of claim 5, wherein the second resource is avoided by other UE which receives the control information, based on that the information bits are non-all zero.

7. The UE of claim 5, wherein the second resource is selected by other UE which receives the control information, based on that the information bits are all zero.

8. The UE of claim 5, wherein the UE does not receive the second data, based on that the information bits are all zero.
