Opportunistic synchronization block transmission for millimeter (mm) wave (mmW) new radio (NR) shared spectrum (NR-SS) is disclosed. In the shared spectrum operations, additional opportunities for synchronization signaling are provided by piggy backing a single shot, opportunistic synchronization (sync) block onto the directional beam used for transmitting a data burst to a served user equipment. Instead of transmitting a whole sync slot, which includes sync blocks for each directional beam available at the participating mmW base station, the existing directional beam of the data burst is leveraged for transmitting the opportunistic sync block for that direction. The opportunistic sync block provides initial acquisition UEs with opportunity to obtain network access information, including timing and random access opportunities, for obtaining access to the network.
