Ultra-Lean Synchronization Procedure for 5G and 6G Networking

Non-transitory computer-readable media in a base station of a wireless network, the media containing instructions that when implemented in a computing environment cause a method to be performed, the method comprising:

• a) determining or receiving a synchronization schedule or format;
• b) determining, according to the synchronization schedule or format, a predetermined transmission time of a first timing signal, a predetermined delay time “Dfreq”, and another predetermined delay time “Dreply”;
• c) transmitting, according to the synchronization schedule or format, the first timing signal;
• d) after the delay time Dfreq, transmitting a second timing signal;
• e) then receiving, from a user device of the wireless network, an uplink timing signal;
• and
• f) after the delay time Dreply, transmitting a downlink timing signal to the user device.

A user device of a wireless network that includes a base station, the base station comprising a base station resource grid, the user device configured to:

• a) configure a transmission resource grid and a reception resource grid, wherein each grid of the base station resource grid, the transmission resource grid, and reception resource grid, comprises symbol-times and sub carriers;
• b) wherein the symbol-times of the reception resource grid are retarded in time, relative to symbol-times of the base station resource grid, by a downlink propagation time;
• and
• c) wherein the symbol-times of the transmission resource grid are advanced in time, relative to the symbol-times of the reception resource grid, by a round-trip propagation time.
