  • Patent number: 10886976
    Abstract: A cloud radio access network (CRAN) system includes a baseband unit (BBU) and a radio unit (RU) remote from the BBU. The fronthaul interface between the RU and the BBU includes a radio frequency interface (RF) functionality implemented in the RU, and implementation of asymmetrical physical layer (PHY) functionality split between the BBU and RU. The asymmetrical physical layer (PHY) functionality split includes: downlink (DL) antenna port mapping and DL precoding implemented in the RU; and the split of the PHY functionality for uplink (UL) at the antenna port mapping in the BBU. For the DL, precoding and resource element (RE) mapping to frequency resources is implemented in BBU, and RE mapping for antenna ports is implemented in the RU|[WA1]. The split also provides support for license-assisted access (LAA) in the CRAN system.

  • Publication number: 20180248787
    Abstract: There is provided a system that includes a local cloud radio access network (RAN), and a remote cloud RAN. The local cloud RAN processes latency-sensitive applications, and the remote cloud RAN processes latency-tolerant applications. User traffic is appropriately routed to the correct cloud RAN based on the application. User equipment (UE) has no knowledge of which network is being used for processing, i.e., this network processing split is done in a manner that is transparent to the UE, e.g., by dynamically selecting a different access point name for local vs. remote processing. The processing split of the RAN between the local cloud RAN and the remote cloud RAN is done in a dynamic manner depending on the number of devices requiring low latency support. This allows the local cloud RAN to be very compact and low-cost since it does not have to process the latency-tolerant traffic.
