  • Patent number: 11729039
    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.

  • Publication number: 20220264525
    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.

  • Patent number: 11363467
    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.

  • Publication number: 20190268777
    Abstract: Wireless system architectures worldwide are undergoing a paradigm shift today. This, by adopting new technology and wireless system architectures based on Software Defined Network (SDN) and Network Function Virtualization (NFV) that are being instantiated using IT cloud computing methods. The 3 GPP is defining a new 5G radio and 5G core network in release 16 based on a cloud native system architecture. Herein, a new next generation multi-channel-tenant virtualized broadcast platform using SDN/NFV is disclosed using ATSC 3.0 standards A/321, A/322 as a baseline.
