Benefits of technology

[0023]According to an embodiment of the present invention, a timing on which a data transmission is started is clearly defined based on SA transmission timing or DCI transmission timing, and a problem of unable to transmit data when failing to receive information for a data transmission timing from a base station.
[0024]In addition, according to an embodiment of the present invention, Time-Resource Pattern for Transmission (T-RPT) pattern which is previously used in relation to a data transmission in Vehicle-to-Everything (V2X) communication is not used, but an indicator indicating spacing between data transmissions is used, and there is an effect of reducing a size of DCI.
[0025]Effects which may be obtained by the present invention are not limited to the aforementioned effects, and other technical effects not described above may be evidently understood by a person having ordinary skill in the art to which the present invention pertains from the following description.

Problems solved by technology

However, as current mobile communication systems suffer resource shortages and users demand even higher-speed services, development of more advanced mobile communication systems is needed.

embodiment 1

T Field

[0476]First, a first embodiment is in relation to a method for (re)using T-RPT field included in the DCI of the existing Sidelink communication for V2X Sidelink communication.

[0477]That is, in the case that the T-RPT field is used in V2X Sidelink communication without any change, all of information for a repeated transmission of data may be indicated in single DCI (up to 4 retransmissions).

[0478]In other words, for a repeated transmission of V2X Sidelink communication of a transmission UE, an eNB transmits V2X sidelink DCI including T-RPT field to the transmission UE.

[0479]By using the T-RPT field, a transmission UE is able to (repeatedly) transmit a message or data to a reception UE on various timings, and flexibility of resource allocation may become significantly increased.

[0480]Particularly, in the case that the T-RPT field is used in the DCI of V2X Sidelink communication, a part of resource collision, half-duplex problem, and the like, which may occur by using different ...

second embodiment

ield

[0537]The second embodiment relates to a method of using another field, not using the T-RPT field included in the DCI of Sidelink communication for the DCI of V2X Sidelink communication.

[0538]The second embodiment may be more efficient than the first embodiment in the following reasons.

[0539]First, since it is required to reduce a size of the DCI in V2X Sidelink communication (Mode 3 and Mode 4), it is preferable to define a new field having a bit number smaller than that of the T-RPT field using 7 bits in the existing Sidelink communication.

[0540]The reason is because there is not so such data transmission amount for V2X Sidelink communication and a problem that resource is wasted may occur in the case that resource is allocated using the existing T-RPT.

[0541]In addition, since mobility is added when a UE drives in fast speed in the V2X Sidelink communication, in the case that resource is allocated in the existing T-RPT pattern method, the V2X Sidelink communication may not be ...

Abstract

The present disclosure proposes a method for transmitting and receiving data through sidelink in a wireless communication system supporting Vehicle-to-Everything (V2X) communication.
Particularly, the method performed by a first User Equipment includes receiving, from a base station, Downlink Control Information (DCI) including information related to a transmission of first control information; transmitting, to the second User Equipment, the first control information based on the received DCI; and transmitting, to the second User Equipment, one or more data through the sidelink.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is the National Stage filing under 35 U.S.C. 371 of International Application No. PCT / KR2017 / 007049, filed on Jul. 3, 2017, which claims the benefit of U.S. Provisional Application No. 62 / 357,393 filed on Jul. 1, 2016, the contents of which are all hereby incorporated by reference herein in their entirety.TECHNICAL FIELD[0002]The present invention relates to a wireless communication system, and more particularly, to a method for transmitting and receiving data between User Equipments in a wireless communication system that supports Vehicle-to-Everything (V2X) communication and an apparatus supporting the same.BACKGROUND ART[0003]Mobile communication systems have been generally developed to provide voice services while guaranteeing user mobility. Such mobile communication systems have gradually expanded their coverage from voice services through data services up to high-speed data services. However, as current mobile commu...
