Abstract

Apparatuses, methods, and systems are disclosed for directional LBT procedure for DRS transmission. One apparatus includes a processor and a transceiver that is operable on unlicensed spectrum. The processor indicates block locations within a Discovery Reference Signal (“DRS”) transmission window for a plurality of candidate Synchronization Signal/Physical Broadcast Channel (“SS/PBCH”) blocks. The processor performs a Listen-Before-Talk (“LBT”) procedure for a plurality of DRS transmissions within a DRS transmission window and controls the transceiver to transmit—for a given spatial direction—a SS/PBCH block upon successful LBT for the given spatial direction.
