Certain aspects of the present disclosure provide a method for wireless communications by a transmitter UE. The method generally includes receiving, from a network entity, a downlink control information (DCI) allocating resources in an unlicensed frequency band for multiple physical sidelink shared channel (PSSCH) transmissions across multiple transmission time intervals (TTIs), performing a listen-before-talk (LBT) channel access procedure in the TTIs, and transmitting, to at least one receiver UE, one or more PSSCHs in one or more of the TTIs being indicated as passing the LBT channel access procedure based on the performance.
