Sidelink channel busy ratio measurements for smaller-bandwidth slots

A method of wireless communication performed by a first user equipment (UE), comprising:

• receiving, from a plurality of second UEs, a plurality of signals over sidelink interfaces between the first UE and the plurality of second UEs;
• and
• performing, to one of the plurality of second UEs, a sidelink transmission using updated transmission parameters based at least in part on a sidelink channel busy ratio (CBR) measurement for a slot, wherein the sidelink CBR measurement for the slot is based at least in part on the plurality of signals and a CBR measurement window that includes one or more of uplink slots and smaller-bandwidth slots, wherein the smaller-bandwidth slots are associated with smaller uplink bandwidths and thereby smaller sidelink bandwidths as compared to the uplink slots, and wherein the sidelink CBR measurement for the slot is based at least in part on a quantity of sub-channels in one of the uplink slots being greater than a quantity of sub-channels in one of the smaller-bandwidth slots.
