Method and device for transmitting information related to slot pattern in nr v2x

A first device for performing 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:
• receive a TDD-UL-DL configuration information, from a base station, including information related to a first slot pattern and information related to a second slot pattern,
• wherein the information related to the first slot pattern includes information related to a periodicity of the first slot pattern and information related to a first UL resource, and
• wherein the information related to the second slot pattern includes information related to a periodicity of the second slot pattern and information related to a second UL resource;
• determine a value related to granularity, based on i) the periodicity of the first slot pattern, ii) the periodicity of the second slot pattern and iii) a first subcarrier spacing (SCS) related to SL communication;
• and
• transmit a physical sidelink broadcast channel (PSBCH), to a second device, including information related to the first UL resource and information related to the second UL resource,
• wherein the information related to the first UL resource and information related to the second UL resource are expressed based on a unit related to a second SCS, and
• wherein the second SCS is obtained based on a value obtained by dividing the first SCS by the value related to the granularity.

A device adapted to control a first user equipment (UE), the device comprising:

• one or more processors;
• and
• one or more memories operably connectable to the one or more processors and storing instructions, wherein the one or more processors execute the instructions to:
• receive a TDD-UL-DL configuration information, from a base station, including information related to a first slot pattern and information related to a second slot pattern,
• wherein the information related to the first slot pattern includes information related to a periodicity of the first slot pattern and information related to a first UL resource, and
• wherein the information related to the second slot pattern includes information related to a periodicity of the second slot pattern and information related to a second UL resource;
• determine a value related to granularity, based on i) the periodicity of the first slot pattern, ii) the periodicity of the second slot pattern and iii) a first subcarrier spacing (SCS) related to SL communication;
• and
• transmit a physical sidelink broadcast channel (PSBCH), to a second UE, including information related to the first UL resource and information related to the second UL resource,
• wherein the information related to the first UL resource and information related to the second UL resource are expressed based on a unit related to a second SCS, and
• wherein the second SCS is obtained based on a value obtained by dividing the first SCS by the value related to the granularity.
