Abstract: A system includes a plurality of remote units and a centralized unit communicatively coupled via a fronthaul network. The centralized unit implements a plurality of multicast groups. The centralized unit determines each of a plurality of sets of data to be sent across the fronthaul network to a respective corresponding subset of the plurality of remote units in the cell. The centralized unit also determines a mapping of each of the plurality of sets of data to a corresponding preferred subset of the plurality of remote units. For a set of data, the centralized unit also transmits the set of data to the corresponding subset of the plurality of remote units over the fronthaul network by multicasting the set of data to a multicast group of the plurality of multicast groups that best matches the corresponding preferred subset of the plurality of remote units mapped to the set of data.

Abstract: One embodiment is directed to a system comprising a distributed unit (DU) and a plurality of remote units (RUs) to wirelessly transmit and receive radio frequency signals to and from the user equipment using a wireless interface. The DU and RUs are communicatively coupled to each other over a fronthaul and are configured to communicate over the fronthaul using an O-RAN fronthaul interface. Management-plane functionality in the system is configured to define a respective transport flow for one or more processing elements using an RU interface that specifies one or more multicast addresses in order to support multicast transmission from the DU to multiple RUs. In another embodiment, each RU is configured to advertise, during a capability discovery process, capabilities related to implementing a switched network shared cell configuration.

Abstract: A C-RAN includes a plurality of remote units; a central unit communicatively coupled to the remote units via a fronthaul network; and an entity coupled to the fronthaul network configured to perform deep packet inspection. The central unit is configured to determine sets of data to be sent to respective subsets of remote units across the fronthaul network and determine a mapping of each of the sets of data to a respective one of the subsets of remote units. The central unit is also configured to add a respective indicator, based on the mapping, to packets for each set of data, wherein each respective indicator indicates each remote unit that the respective packet and set of data is intended for. The central unit is also configured to transmit the packets for the sets of data, each with the respective indicator, to the entity over the fronthaul network.

Abstract: In one embodiment, a distributed unit (DU) is configured to do the following in connection with wirelessly transmitting user data to a UE using less than all of a plurality of radio units (RUs): include, in one or more user-plane messages for that UE that are communicated to the RUs, common header fields that contain a RU mask field for storing a bit mask comprising a plurality of bit positions. Each bit position is associated with a respective one of the RUs. Each RU is configured to: use the respective RU mask field included in any user-plane messages received by that RU in order to determine if the received user-plane message is intended for that RU and use the received message if the received message is intended for that RU and discard the received message if the received message is not intended for that RU.
