14. A method of wireless communication at a first user equipment (UE), comprising:
calculating a channel busy ratio (CBR) associated with a sidelink resource pool over a measurement window, the measurement window corresponding to a plurality of slots, a partially used slot-subchannel block in the plurality of slots being associated with a non-zero contribution to the CBR, the partially used slot-subchannel block including at least one used mini slot-subchannel block, wherein an average received signal strength over the partially used slot-subchannel block is less than a first threshold, and an average received signal strength over the at least one used mini slot-subchannel block is greater than a second threshold;
identifying a channel occupancy ratio (CR) limit associated with the sidelink resource pool based on the CBR;
selecting one or more resources associated with a slot from the sidelink resource pool for a sidelink transmission to a second UE based at least in part on the CR limit; and
transmitting, to the second UE, the sidelink transmission based on the selected one or more resources.
