1. A method for wireless communications by a transmitter user equipment (UE), comprising:
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 multiple TTIs; and
transmitting, to at least one receiver UE, one or more PSSCHs in one or more of the multiple TTIs being indicated as passing the LBT channel access procedure based on the performance.
