Abstract
Provided, according to one embodiment of the present disclosure, is a method for a first device transmitting a PSCCH and a PSSCH to a second device. The method may comprise the steps of: determining whether, in the entire frequency band of one PSSCH sub-channel, a first DMRS symbol is occupied by a resource region associated with a PSCCH; on the basis of whether the first DMRS symbol is occupied by the resource region associated with the PSCCH, determining a position, of a reference symbol in a PSSCH resource, in which a second SCI is mapped; mapping the second SCI on the basis of the position of the reference symbol in the PSSCH resource; and transmitting the second SCI to a second device via the PSSCH.
Claims14
A method for a first apparatus to transmit a physical sidelink control channel (PSCCH) and a physical sidelink shared channel (PSSCH) to a second apparatus, the method including:
- determining whether a first demodulation reference signal (DMRS) symbol among a plurality of DMRS symbols for the PSSCH in at least one PSSCH subchannel related to the PSSCH is occupied by a resource area for the PSCCH in a whole frequency band of one PSSCH subchannel among the at least one PSSCH subchannel;
- determining a location of a reference symbol in a PSSCH resource in which a second sidelink information (SCI) is mapped based on whether the first DMRS symbol is occupied by the resource area for the PSCCH in the whole frequency band of the one PSSCH subchannel;
- mapping the second SCI based on the location of the reference symbol in the PSSCH resource;
- and
- transmitting the second SCI to the second apparatus through the PSSCH.
A first apparatus for transmitting a physical sidelink control channel (PSCCH) and a physical sidelink shared channel (PSSCH) to a second apparatus, the first apparatus comprising:
- at least one memory to store instructions;
- at least one transceiver;
- and
- at least one processor to connect the at least one memory and the at least one transceiver,
- wherein the at least one processor is configured to:
- determine whether a first demodulation reference signal (DMRS) symbol among a plurality of DMRS symbols for the PSSCH in at least one PSSCH subchannel related to the PSSCH is occupied by a resource area for the PSCCH in a whole frequency band of one PSSCH subchannel among the at least one PSSCH subchannel,
- determine a location of a reference symbol in a PSSCH resource in which a second sidelink information (SCI) is mapped based on whether the first DMRS symbol is occupied by the resource area for the PSCCH in the whole frequency band of the one PSSCH subchannel,
- map the second SCI based on the location of the reference symbol in the PSSCH resource, and
- control the at least one transceiver to transmit the second SCI to the second apparatus through the PSSCH.
An apparatus for controlling a first terminal, the apparatus comprising:
- at least one processor;
- and
- at least one computer memory that is connected to be executable by the at least one processor and stores instructions,
- wherein, when the at least one processor executes the instructions, the first terminal is configure to:
- determine whether a first demodulation reference signal (DMRS) symbol among a plurality of DMRS symbols for the PSSCH in at least one PSSCH subchannel related to the PSSCH is occupied by a resource area for the PSCCH in a whole frequency band of one PSSCH subchannel among the at least one PSSCH subchannel,
- determine a location of a reference symbol in a PSSCH resource in which a second sidelink information (SCI) is mapped based on whether the first DMRS symbol is occupied by the resource area for the PSCCH in the whole frequency band of the one PSSCH subchannel,
- map the second SCI based on the location of the reference symbol in the PSSCH resource, and
- transmit the second SCI to a second terminal through the PSSCH.
