Abstract: A C-RAN includes a plurality of remote units (RUs), each being configured to exchange RF signals with at least one UE. The C-RAN also includes a central unit communicatively coupled to the plurality of RUs via a fronthaul interface. The fronthaul interface includes at least one ETHERNET switch configured to perform deep packet inspection on a received packet in order to determine whether an RU identification is present in the packet. The RU identification, if present in the packet, indicates at least one RU the packet is intended for. When the RU identification is present in the packet, the at least one ETHERNET switch is also configured to communicate, for each of the at least one RU, at least a portion of the packet to the RU based on a comparison of the RU identification with at least one bit pattern for the RU.

Abstract: A C-RAN includes a plurality of remote units; and a central unit communicatively coupled to the remote units via a fronthaul network. The central unit is configured to determine sets of data to be sent to respective subsets of remote units across the fronthaul network. The central unit is also configured to 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, for each of the sets of data, if at least one of the multicast groups wholly contains the respective subset of remote units mapped to that set of data, transmit that set of data to the respective subset of remote units over the fronthaul network by multicasting that set of data to the multicast group that best matches the respective subset of remote units mapped to that set of data.

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.

Abstract: A distributed radio access network (RAN) includes a new radio unit (RU) being connected to a front-haul network. The new RU determines its own Internet Protocol (IP) address based on its MAC address; and send a discovery message to all radio controllers in the front-haul network via a multicast address. The distributed RAN also includes a plurality of radio controllers communicatively coupled to the new RU via the front-haul network. Each of the plurality of radio controllers are configured to receive the discovery message and determine whether the new RU is assigned to the respective radio controller. Each of at least one radio controller, to which the new RU is assigned, establishes at least one configuration session with the new RU.
