Feedback transmission via a sidelink feedback channel resource of a sidelink resource pool

A first user equipment (UE) for wireless communication, comprising:

• a memory;
• and
• one or more processors coupled to the memory, the one or more processors configured to cause the UE to:
• receive, from a second UE and in a sidelink resource of a sidelink resource pool of a sidelink component carrier of a group of preconfigured sidelink component carriers, information via a sidelink interface between the first UE and the second UE;
• and
• transmit, to the second UE, sidelink hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback using a sidelink feedback channel resource of the sidelink resource pool via the sidelink component carrier of the group of sidelink component carriers based at least in part on the information received from the second UE, wherein the sidelink resource pool is based at least in part on a common sidelink feedback channel configuration associated with the group of preconfigured sidelink component carriers.
