Abstract
The present invention provides a method by which a terminal performs vehicle-to-everything (V2X) transmission resource selection in a wireless communication system, the method mapping, onto a subframe, a coded symbol related to control information and transmitting the control information by using the mapped coded symbol, wherein the control information is piggybacked and transmitted together with data, and the coded symbol related to the control information is mapped before the data.
Claims9
A method for selecting vehicle-to-everything (V2X) transmission resources by a UE in a wireless communication system, the method comprising:
- mapping coded symbols related to control information on a physical sidelink shared channel (PSSCH),
- wherein the PSSCH is a channel used for data transmission between UEs;
- and
- transmitting the control information using the mapped coded symbols,
- wherein the control information is piggybacked along with data and transmitted based on the PSSCH, and the coded symbols related to the control information are mapped prior to the data,
- wherein resource elements of the coded symbols related to the control information are different from resource elements of the data in the PSSCH, and
- wherein at least one of the coded symbols related to the control information is allocated in a symbol carrying a first reference signal.
A user equipment (UE) comprising:
- a transceiver for transmitting and receiving signals;
- and
- a processor operating in connection with the transceiver,
- wherein, in a method for selecting vehicle-to-everything (V2X) transmission resources by the UE in a wireless communication system, the processor is configured:
- to map coded symbols related to control information on a physical sidelink shared channel (PSSCH),
- wherein the PSSCH is a channel used for data transmission between UEs;
- and
- to transmit the control information using the mapped coded symbols,
- wherein the control information is piggybacked along with data and transmitted based on the PSSCH, and the coded symbols related to the control information are mapped prior to the data,
- wherein resource elements of the coded symbols related to the control information are different from resource elements of the data in the PSSCH, and
- wherein at least one of the coded symbols related to the control information is allocated in a symbol carrying a first reference signal.
