Method and apparatus for selecting sl resources in nr v2x

A first device configured 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:
• determine one or more logical channels of interest from among a plurality of logical channels;
• based on sidelink (SL) hybrid automatic repeat request (HARQ) feedback being enabled for at least one logical channel among the one or more logical channels of interest, allocate N SL processes, from among a plurality of SL processes for transmitting a plurality of medium access control protocol data units (MAC PDUs), to a SL resource in which a physical sidelink feedback channel (PSFCH) resource is configured;
• and
• perform HARQ feedback-based SL communication based on the N SL processes,
• wherein N is a positive integer.

An apparatus configured to control a first user equipment (UE), the apparatus 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:
• determine one or more logical channels of interest from among a plurality of logical channels;
• based on sidelink (SL) hybrid automatic repeat request (HARQ) feedback being enabled for at least one logical channel among the one or more logical channels of interest, allocate N SL processes, from among a plurality of SL processes for transmitting a plurality of medium access control protocol data units (MAC PDUs), to a SL resource in which a physical sidelink feedback channel (PSFCH) resource is configured;
• and
• perform HARQ feedback-based SL communication based on the N SL processes,
• wherein N is a positive integer.
