1. A method for wireless communication by a first user equipment (UE), the method comprising:
identifying a resource pool allocated for sidelink communications between the first UE and at least a second UE, wherein:
the resource pool consists of a plurality of sub-channels and one more remaining physical resource blocks (PRBs);
each of the plurality of sub-channels having a same number of PRBs equal to a sub-channel size;
the number of PRBs comprises a plurality of PRBs; and
a total number of the one or more remaining PRBs is fewer than the number of PRBs equal to the sub-channel size;
communicating feedback on a physical sidelink feedback channel (PSFCH) on the plurality of sub-channels; and
using the one or more remaining PRBs for sidelink communications.
