Method and apparatus for transceiving messages from V2X terminal in wireless communication system
One embodiment of the present invention relates to a method for a terminal transmitting a message in a wireless communication system, comprising the steps of: generating a message; and transmitting, from a resource sectioned on a time axis, control information for the message and the message when the size of the message is larger than a predetermine value, and transmitting, from a resource sectioned on a frequency axis, the control information for the message and the message when the size of the message is smaller than the predetermined value.
1. A method of transmitting a PSSCH (Physical sidelink shared channel), which is transmitted by a user equipment (UE) in a wireless communication system, the method comprising:
generating a PSSCH based on information included in a PSCCH (Physical sidelink control channel); and
transmitting the generated PSSCH with the PSCCH in a subframe,
wherein sequences for the PSSCH are scrambled by using a value related to a CRC (Cyclic Redundancy Check) field on the received PSCCH.
2. The method of claim 1 ,
wherein a reference signal for the PSSCH is also generated by using the value related to the CRC field on the received PSCCH.
3. The method of claim 1 ,
wherein a resource allocation field included in the PSCCH indicates a subchannel based resource allocation.
4. The method of claim 3 ,
wherein a size of a subchannel is indicated via higher layer signaling.
5. The method of claim 3 ,
wherein the UE performs a subchannel based resource selection for the PSSCH transmission.
6. The method of claim 1 , wherein the UE is a V2X (Vehicle to Everything) UE.
7. The method of claim 1 , wherein the PSCCH includes an information related to a UE type.
8. A user equipment (UE) in a wireless communication system, the UE comprising:
a transmitter and a receiver; and
a processor, the processor configured to generate a PSSCH (Physical sidelink shared channel) based on information included in a PSCCH (Physical sidelink control channel), the processor configured to transmit the generated PSSCH with the PSCCH in a subframe,
wherein sequences for the PSSCH are scrambled by using a value related to a CRC (Cyclic Redundancy Check) field on the received PSCCH.
