1. A first wireless transmit/receive unit (WTRU) that performs wireless communication comprising:
a processor; and
a memory coupled with the processor, the memory comprising executable instructions stored thereon that when executed by the processor cause the processor to effectuate operations comprising:
communicating with a second WTRU;
counting a number of received negative-acknowledgement (NACK) feedbacks or no feedbacks from the second WTRU;
based on the number of received NACK feedbacks or no feedbacks exceeding a first threshold, sending a beam failure indication;
reporting a link quality indication that is below a quality threshold; and
based on the beam failure indication and the link quality indication that is below the quality threshold, transmitting a beam sweeping burst, wherein the beam sweeping burst is a composite of multiple blocks, wherein each block of the multiple blocks comprises physical sidelink shared channel (PSSCH).
