Atsc 3.0 single frequency networks used for positioning navigation timing and synergy 4g / 5g networks

An apparatus, comprising:

• a memory to store instructions;
• and
• a processor configured to perform the instructions to:
• select a length for an advanced television system committee (ATSC) 3.0 frame for transmission by a single frequency network (SFN) transmitter;
• align the SFN transmitter with a global positioning system (GPS) epoch;
• store geographical coordinates of the SFN transmitter and a corresponding SFN transmitter identification (TX ID) in a database;
• encode the SFN TX ID in a plurality of positioning navigation timing (PNT) symbols;
• prepend the plurality of PNT symbols to the ATSC 3.0 frame to generate a modified ATSC 3.0 frame;
• and
• transmit the modified ATSC 3.0 using a SFN transmitter antenna of the SFN transmitter.

A non-transitory computer-readable medium includes instructions stored thereon that, when executed by at least one computing device, cause the at least one computing device to perform operations comprising:

• selecting a length for an advanced television system committee (ATSC) 3.0 frame for transmission by a single frequency network (SFN) transmitter;
• aligning the SFN transmitter with a global positioning system (GPS) epoch;
• storing geographical coordinates of the SFN transmitter and a corresponding SFN transmitter identification (TX ID) in a database;
• encoding the SFN TX ID in a non-coherent symbol of a plurality of positioning navigation timing (PNT) symbols comprising a plurality of coherent symbols and the non-coherent symbol with orthogonal frequency-division multiplexing (OFDM) numerology to support positioning;
• prepending the plurality of PNT symbols to the ATSC 3.0 frame to generate a modified ATSC 3.0 frame;
• and
• transmitting the modified ATSC 3.0 using a SFN transmitter antenna of the SFN transmitter.
