    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 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 according to the policy guidance. The generated baseband packet is compatible for transmission in the plurality of radio technologies.

    Abstract: Some aspects of this disclosure are direct to a system that includes a first scheduler configured to receive an input packet and generate a first packet to be transmitted using a first radio unit (RU). The system further includes a second scheduler configured to receive the first packet from the first scheduler and generate a second packet. The second packet is to be transmitted using a second RU. The system further includes a first fronthaul operated using evolved Common Public Radio Interface (eCPRI) protocol and configured to direct the first packet to the first RU to be transmitted on a first channel having a first frequency. The system further includes a second fronthaul operated using the eCPRI protocol and configured to direct the second packet to the second RU to be transmitted on a second channel having a second frequency different from the first frequency.

    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: 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.
