摘要： 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, transmitter may use a portion of its transmission time to relay in-band information to the singlefrequency network transmitter using time-division multiplexing.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
