Downlink synchronization

An apparatus for a wireless communication comprising:

• a non-transitory memory including instructions stored thereon for performing the wireless communication;
• and
• a processor, operably coupled to the non-transitory memory, capable of executing the instructions of:
• performing a search for a cell in a network;
• detecting a primary synchronization signal of the cell;
• identifying a secondary synchronization signal of the cell;
• synchronizing with the cell;
• and
• decoding a physical broadcast channel of the cell using sync numerology,
• wherein a subcarrier spacing factor is obtained either from the detected primary synchronization signal or the detected second synchronization signal.

An apparatus for a wireless communication comprising:

• a non-transitory memory including instructions stored thereon for performing the wireless communication;
• and
• a processor, operably coupled to the non-transitory memory, capable of executing the instructions of:
• preparing a beam sweeping block carrying downlink initial access signals including a first synchronization signal, a second synchronization signal, a beam reference signal and a PBCH;
• and
• transmitting the beam sweeping block to user equipment,
• wherein the user equipment is configured to determine, based on the downlink initial access signals, an identity of the beam sweeping block associated with the downlink initial access signal, and
• wherein a part of the identity of the beam sweeping block is associated with the beam reference signal.
