1. A method of wireless communication performed by a first sidelink user equipment (UE), the method comprising:
transmitting to a base station (BS), a buffer status report (BSR) indicating an amount of data to be transmitted from the first sidelink UE to a second sidelink UE;
receiving, from the BS, a configuration indicating a listen-before-talk (LBT) window for sidelink communications between the first sidelink UE and the second sidelink UE, wherein the configuration indicates a start and an end associated with the LBT window and a maximum channel occupancy time (COT) duration, wherein the maximum COT duration is based on the BSR;
performing, during the LBT window, an LBT for a COT in a shared radio frequency band; and
transmitting, to the second sidelink UE, based on the LBT being successful, one or more transport blocks (TBs) during the COT using the maximum COT duration.
