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.

ATSC 3.0 multicast-broadcast intelligent RAN topologies

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.

ATSC 3.0 single frequency networks used for positioning navigation timing and synergy 4G / 5G networks

The ATSC 3.0 physical layer broadcast standard is extended with new OFDM numerology, L1 signaling and frame structure aligned with 5G. This is done to enable improved broadcast mobility and convergence 5G release 16 as a Non-3GPP access network. The 5G core network and Broadcast core network interwork over defined interfaces to enable convergence layer 3. This enables improvements of broadcast physical layer for physics of broadcast. The 5G unicast physical layer is enhanced for physics of unicast, and then both are converged at layer 3. This is novel and has many benefits compared to the legacy LTE broadcast method (e.g., Evolved Multimedia Broadcast Multicast Services (eMBMS)), which combines both broadcast and unicast into a single shared LTE frame at layer 1. The eMBMS method is then improved for dominate unicast mode in shared L1 frame. The result is the broadcast performance and efficiency in eMBMS are less than optimal.

Methods and systems for extending ATSC 3.0 physical layer broadcast to enable convergence with unicast 5G

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.

Enabling efficient deterministic virtualized broadcast spectrum sharing and usage validation

A system and method for dynamically switching transmission of selected data from cellular core network to unidirectional point-to-multipoint downlink network or from unidirectional point-to-multipoint downlink network to cellular core network based on traffic flow analysis is provided. The system includes a cellular packet core, a broadcast offload packet core (BO-PC), and a load manager. The cellular packet corecontrols a cellular radio access network (RAN)for providing bidirectional connectivity to a converged user equipment (UE) () to transmit or receive selected data through the cellular packet coreand the RAN. The BO-PCcontrols a broadcast radio access network (RAN). The broadcast radio access network (RAN) includes at least one Broadcast Radio Head (BRH)for providing unidirectional downlink path to the converged user equipment (UE)to receive selected data through the at least one Broadcast Radio Heads (BRH)

System and method for dynamically switching transmission of data from cellular to unidirectional point-to-multipoint network

A Next Generation Broadcast Platform (NGBP) is disclosed that utilizes 5G software-defined networking (SDN) and network function virtualization (NFV) technologies. The NGBP is designed to enable a new paradigm for broadcasters, wherein the model of fixed wireless spectrum access granted only to the licensees of the spectrum is replaced by a flexible model in which licensed spectrum is pooled together and allocated dynamically to broadcast licensees as well as outside tenants. The NGBP is implemented using SDN/NFV technology, and includes a broadcast market exchange (BMX) entity that allocates the spectrum between tenants based on service level agreements (SLAs) with those users. The NGBP also includes an internet protocol (IP) core and a broadcast centralized radio access network (BC-RAN) which apply the major network functions to broadcaster content in accordance with the determinations of the BMX. The SDN/NFV implementation offers several distinct advantages over NGBP implemented with dedicated network hardware.

Next generation terrestrial broadcasting platform aligned internet and towards emerging 5G network architectures

A new television broadcast model called a Broadcast Market Exchange (BMX) eliminates the inefficiency in spectrum usage, providing maximum flexibility in delivering content through either VHF (for fixed location receiving devices) or UHF (optimized for mobile receiving devices) transmission/propagation. In conjunction with the BMX, a wireless communications system architecture is provided to enable a broadcast augmentation channel. The augmentation channel provides supplementation of the Quality of Service (QoS) of a one way User Datagram Protocol (UDP) delivery environment. The augmentation channel may be comprised of one or more physical delivery mechanisms (wired or wireless), but can be effectively unified for increasing QoS and or scalable levels of service (additional essence) to improve the user experience.
