Method and device for transmitting and receiving auxiliary information in nr v2x

A first device adapted to perform wireless communication, the first device comprising:

• one or more memories storing instructions;
• one or more transceivers;
• and
• one or more processors connected to the one or more memories and the one or more transceivers, wherein the one or more processors execute the instructions to:
• obtain a sidelink (SL) discontinuous reception (DRX) configuration;
• control the one or more transceivers to receive, from a second device through a physical sidelink control channel (PSCCH), sidelink control information (SCI) including scheduling information for a physical sidelink shared channel (PSSCH), wherein the SCI includes information related to frequency resource assignment, information related to time resource assignment, information related to a demodulation reference signal (DMRS) pattern, and information related to a modulation and coding scheme (MCS);
• control the one or more transceivers to receive, from the second device through the PSSCH, first inter-UE coordination information including information related to a set of preferred resources or information related to a set of non-preferred resources;
• select at least one SL resource based on the first inter-UE coordination information;
• and
• trigger resource reselection based on the at least one SL resource which is not in an active time of the SL DRX configuration.

A processing device adapted to control a first device, the processing device comprising:

• one or more processors;
• and
• one or more memories operably connected to the one or more processors and storing instructions, wherein the one or more processors execute the instructions to:
• obtain a sidelink (SL) discontinuous reception (DRX) configuration;
• receive, from a second device through a physical sidelink control channel (PSCCH), sidelink control information (SCI) including scheduling information for a physical sidelink shared channel (PSSCH), wherein the SCI includes information related to frequency resource assignment, information related to time resource assignment, information related to a demodulation reference signal (DMRS) pattern, and information related to a modulation and coding scheme (MCS);
• receive, from the second device through the PSSCH, first inter-UE coordination information including information related to a set of preferred resources or information related to a set of non-preferred resources;
• select at least one SL resource based on the first inter-UE coordination information;
• and
• trigger resource reselection based on the at least one SL resource which is not in an active time of the SL DRX configuration.
