1. A method for broadcast spectrum sharing, the method comprising:
receiving data from a plurality of data sources in a broadcast core network for transmission over a radio access network (RAN);
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;
generating a baseband packet corresponding to the data at a distributed unit (DU) in the RAN;
collecting transmission data from a plurality of user equipments (UEs) in the RAN for training a machine learning algorithm; and
scheduling transmission of the baseband packet to a remote unit (RU) over a fronthaul in a radio topology of a plurality of radio topologies stored in a database under control of the machine learning algorithm according to the policy guidance,
wherein the baseband packet is compatible for transmission in the plurality of radio technologies to optimize sharing of the radio spectrum resources of the plurality of radio topologies among the plurality of network operators.
