    Abstract: Disclosed herein are methods, an apparatus, and a computer-readable medium product for sharing broadcast resources and validating usage of the broadcast resources according to an agreement between a plurality of broadcast virtual network operators (BVNOs). A method includes determining the plurality of spectrum resources corresponding to a length of a broadcast frame, and creating a plurality of physical layer pipes (PLPs) based on a plurality of internet protocol (IP) flows from the plurality of BVNOs. The method includes constructing the broadcast frame including the plurality of PLPs and generating a broadcast frame record based on transmission of the broadcast frame. The broadcast frame record can identify the plurality of spectrum resources shared between the plurality of BVNOs. The method includes updating the broadcast frame record with identification information of the plurality of BVNOs and the plurality of IP flows corresponding to the plurality of PLPs of the broadcast frame.

    Abstract: According to some embodiments, a method includes selecting a length for an advanced television system committee (ATSC) 3.0 frame for transmission by a single frequency network (SFN) transmitter and aligning the SFN transmitter with a global positioning system (GPS) epoch. The method further includes storing geographical coordinates of the SFN transmitter and a corresponding SFN transmitter identification (TX ID) in a database. The method also includes 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. The method further includes 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.

    Abstract: An apparatus and a method are provided for generating and transmitting one or more band segmented bootstrap signals. For example, a transmitter may be configured to generate a plurality of sequence numbers and apply cyclic shift to each of the plurality of sequence number. The transmitter is further configured to map each of the shifted sequence numbers to at least one frequency domain subcarrier of a plurality of frequency domain subcarriers, and translate each subcarrier of the plurality of subcarriers to a time domain sequence. Each subcarrier of the plurality of subcarriers may be shifted with respect to other subcarriers of the plurality of subcarriers, thereby aligning each segment of the band segmented bootstrap signals next to each other in the frequency domain.

    Abstract: Systems and methods for one-way time transfer using physical layer signaling are disclosed herein. According to some examples, a method includes generating timing information based on a clock of a transmitting device, where the timing information comprises a timestamp and metadata. The method further includes generating a preamble of a frame, where the preamble includes the timestamp and the metadata of the timing information. The method also includes forming a frame, where the frame comprises a bootstrap, the preamble, and a payload, and transmitting the frame to a receiver device. The one-way time transfer systems and methods of this disclosure can serve mobile devices that entail quick and reliable establishment of a clock.
