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: Systems and methods for relaying in broadcast single-frequency networks are disclosed herein. A single-frequency network can be formed in part using transmitters that receive data via a cooperative relay channel instead of a station-to-transmitter link. In some embodiments, a second channel may use a portion of its transmission time to relay the information to the single-frequency network transmitter using time-division multiplexing. In other embodiments, a second channel may encode the relayed information on a second layer using layer-division multiplexing.

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: A method disclosed includes receiving data from a plurality of data sources in a broadcast core network for transmission over a radio access network (RAN). The method includes assigning radio spectrum resources for transmitting the data over the RAN according to a policy guidance set by a plurality of network operators for sharing the radio spectrum resources and generating a baseband packet corresponding to the data at a distributed unit (DU) in the RAN. The method includes collecting transmission data from a plurality of user equipments (UEs) in the RAN for training a machine learning algorithm and scheduling transmission of the generated baseband packet to a remote unit (RU) over a fronthaul in a radio topology of a plurality of radio topologies under control of the machine learning algorithm according to the policy guidance. The generated baseband packet is compatible for transmission in the plurality of radio technologies.

Abstract: Systems and methods for relaying in broadcast single-frequency networks are disclosed herein. A single-frequency network can be formed in part using transmitters that receive data via a cooperative relay channel instead of a studio-to-transmitter link. In some embodiments, transmitter may use a portion of its transmission time to relay in-band information to the single-frequency network transmitter using time-division multiplexing.
