Abstract
The present invention provides a method by which a vehicle-to-X (V2X) terminal performs a V2X operation in a wireless communication system, comprising: determining a physical sidelink control channel (PSCCH) and a physical sidelink shared channel (PSSCH), which are related to a specific transport block to be transmitted; and transmitting the PSCCH and the PSSCH, which are related to the transport block, wherein the PSCCH and the PSSCH are transmitted continuously during a transmission period.
Claims9
A method for transmitting at least one physical sidelink control channel (PSCCH) and at least one physical sidelink shared channel (PSSCH) in a wireless communication system, the method comprising:
- determining the at least one PSCCH and the at least one PSSCH to be transmitted,
- wherein both the at least one PSCCH and the at least one PSSCH are related to a specific transport block (TB);
- and
- transmitting the at least one PSCCH and at least one PSSCH related to the transport block,
- wherein both the at least one PSCCH and the at least one PSSCH are transmitted during a transmission duration for the specific TB, and
- wherein, based on a channel busy ratio (CBR) being low:
- the at least one PSCCH is transmitted on at least one first subframe distinguished from at least one second subframe, on which the at least one PSSCH is transmitted,
- the at least one first subframe is adjacent to the at least one second subframe on the time axis, and
- the at least one first subframe and the at least one second subframe are located during the transmission duration.
A vehicle-to-X (V2X) user equipment (UE) comprising:
- a transceiver;
- and
- a processor operatively coupled to the transceiver, wherein the processor is configured to:
- determine at least one physical sidelink control channel (PSCCH) and at least one physical sidelink shared channel (PSSCH) to be transmitted,
- wherein both the at least one PSCCH and the at least one PSSCH are related to a specific transport block (TB);
- and
- control the transceiver to transmit the at least one PSCCH and the at least one PSSCH,
- wherein both the at least one PSCCH and the at least one PSSCH are transmitted during a transmission duration for the specific TB, and
- wherein, based on a channel busy ratio (CBR) being low:
- the at least one PSCCH is transmitted on at least one first subframe distinguished from at least one second subframe, on which the at least one PSSCH is transmitted,
- the at least one first subframe is adjacent to the at least one second subframe on the time axis, and
- the at least one first subframe and the at least one second subframe are located during the transmission duration.
