Method and apparatus for performing communication on basis of dci in nr v2x

A method for performing wireless communication by a base station, the method comprising:

• transmitting, to a device, information related multiple resource pools;
• and
• transmitting, to the device, a new radio (NR) sidelink (SL) downlink control information (DCI) format for scheduling an NR SL resource through a physical downlink control channel (PDCCH),
• wherein, based on that the multiple resource pools are configured for the device, at least one of sizes of the NR SL DCI format is aligned by appending at least one zero bit with a largest size of the NR SL DCI format related with the multiple resource pools.

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

• one or more processors;
• and
• one or more memories connected to the one or more processors and storing instructions, wherein the one or more processors execute the instructions to:
• obtain information related multiple resource pools;
• and
• monitor a physical downlink control channel (PDCCH) for detection of a new radio (NR) sidelink (SL) downlink control information (DCI) format for scheduling an NR SL resource,
• wherein, based on that the multiple resource pools are configured for the device, at least one of sizes of the NR SL DCI format is aligned by appending at least one zero bit with a largest size of the NR SL DCI format related with the multiple resource pools.
