Methods and apparatus for new radio initial synchronization and paging

A wireless transmit/receive unit (WTRU) comprising:

• a receiver configured to receive, from a base station (BS), a plurality of synchronization signals transmitted using multiple beams of the BS;
• circuitry configured to compare a received energy of each beam received by the WTRU of the multiple beams against a first threshold to identify a subset of the multiple beams of the BS;
• the circuitry further configured to compare an accumulated received energy of each beam of the subset against a second threshold;
• the circuitry further configured to determine, from the plurality of synchronization signals, control information of the BS, wherein the control information comprises timing information including an orthogonal frequency division multiplexing (OFDM) symbol index, a synchronization signal block index or beam sweep timing information;
• and
• a receiver configured to receive data, from the BS, on a beam of the subset in accordance with the determined control information.
