Synchronization signal block transmissions in non-terrestrial networks

An apparatus of wireless communication in a non-terrestrial network (NTN), comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor, the memory comprising code executable by the at least one processor to cause the apparatus to:
• send a first synchronization signal block (SSB) at a first time and frequency location;
• determine one or more time and frequency locations of one or more other SSBs based on the first time and frequency location and a configured or predefined time and frequency pattern or mapping of the first SSB and the one or more other SSBs;
• and
• send the one or more other SSBs at the one or more time and frequency locations.

A method of wireless communication by a user equipment, comprising:

• receiving a first synchronization signal block (SSB) from an entity in a non-terrestrial network (NTN) at a first time and frequency location;
• determining one or more time and frequency locations of one or more other SSBs from the entity in the NTN based on the first time and frequency location and a configured or predefined time and frequency pattern or mapping of the first SSB and the one or more other SSBs;
• and
• monitoring for the one or more other SSBs at the one or more time and frequency locations.
