Method and device for transmitting and receiving message by V2X terminal in wireless communication system
First Claim
1. A method of receiving or transmitting data, by a first user equipment (UE) in a wireless communication system, the method comprising:
- 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 indicated by the control information,wherein the control information includes information bits which indicate that the second UE does not keep the first frequency resource when the information bits are all zero, and indicate both an interval and that the second UE keeps the first frequency resource when the information bits are not all zero, wherein the kept first frequency resource is in a next subframe of a last subframe of the interval, repeatedly,wherein the first UE receives a second data from the second UE on a second frequency resource having same frequency location with the first frequency resource in the next subframe of the last subframe of the interval, when the information bits indicate the second UE keeps the first frequency resource and the first data indicated by the control information is transmitted to the first UE,wherein the first UE transmits a third data on a third frequency resource having different frequency location with the first frequency resource in the next subframe of the last subframe of the interval, when the information bits indicate the second UE keeps the first frequency resource and the first data indicated by the control information is not transmitted to the first UE, andwherein the interval is determined by a value selected by the second UE from among a plurality of values and wherein the plurality of the values are allowed by a period-related parameter forwarded via higher layer signaling.

Abstract
A method for transmitting data by a UE in a wireless communication system, according to an embodiment of the present invention, comprises the steps of: transmitting a first message through time-frequency resources; and, if a UE must transmit a second message which is related to the first message, transmitting the second message through a frequency resource region which is the same as a frequency resource region in the time-frequency resources after predetermined time from the time-frequency resources, wherein the predetermined time is determined on the basis of bits selected from a plurality of bits by means of the UE, wherein the bits which can be selected from the plurality of bits by means of the UE are permitted by a period-related parameter transferred by means of upper layer signaling.

8. A first user equipment (UE) in a wireless communication system, the first UE comprising:
-
a transmitter and a receiver; and a processor, wherein the processor receives control information, from a second UE, through a control channel and transmits or receives a first data based on a first frequency resource indicated by the control information, wherein the control information includes information bits which indicate that the second UE does not keep the first frequency resource when the information bits are all zero, and indicate both an interval and that the second UE keeps the first frequency resource when the information bits are not all zero, wherein the kept first frequency resource is in a next subframe of a last subframe of the interval, repeatedly, wherein the first UE receives a second data from the second UE on a second frequency resource having same frequency location with the first frequency resource in the next subframe of the last subframe of the interval, when the information bits indicate the second UE keeps the first frequency resource and the first data indicated by the control information is transmitted to the first UE, wherein the first UE transmits a third data on a third frequency resource having different frequency location with the first frequency resource in the next subframe of the last subframe of the interval, when the information bits indicate the second UE keeps the first frequency resource and the first data indicated by the control information is not transmitted to the first UE, and wherein the interval is determined by a value selected by the second UE from among a plurality of values and wherein the plurality of the values are allowed by a period-related parameter forwarded via higher layer signaling. - View Dependent Claims (9, 10, 11, 12, 13, 14)
