    Abstract: One embodiment is directed to using a set of multi-cell virtual network functions (VNFs) that natively perform baseband processing necessary to provide wireless service to user equipment (UEs) using multiple cells. Respective demand information for each cell is determined. A respective allocation of the one or more resources for each cell is determined based on the demand information for the multiple cells. For each cell scheduling of the respective UEs is performed for that cell with an objective of ensuring that a respective demand for the one or more resources in connection with serving that cell does not exceed the capacity associated with the respective allocation of the one or more resources for that cell and baseband processing necessary to provide respective wireless service via that cell is performed in accordance with the scheduling for that cell. Other embodiments are disclosed.

    Abstract: The present disclosure describes methods and apparatus for real-time physical layer processing in distributed units (DU). A downlink data processing method includes receiving a downlink transport block at the physical layer and generating a plurality of sub-transport blocks mapped to a plurality of symbols by processing the received transport block. The method further includes processing the plurality of sub-transport blocks sequentially using at least one transfer function to generate the plurality of symbols which are then transmitted to a radio unit (RU) for transmission to a user equipment (UE). An uplink data processing method includes generating an uplink transport block by processing a plurality of symbols received at the DU from the RU. The plurality of symbols are processed using at least one uplink transfer function. A downlink/uplink transfer function is functionally equivalent to a plurality of down-link/uplink sequential signal processing modules.

    Abstract: One embodiment is directed to a system that is configured to communicate at least two different types of fronthaul data from a plurality of baseband units to a shared radio point using a single application-layer protocol that supports at least two types of elements. Each of the at least two types of elements is configured for a respective one of the at least two different types of fronthaul data. The system is configured so at least some of the elements communicated using the application-layer protocol include one or more sub-elements, where each sub-element comprises a type field, a length field, and a value portion.

    Abstract: A communication system comprising remote units and controllers or controller resources is described. The controllers or controller resources are configured to assign airlink resources to the user equipment, the airlink resources being for transmission or reception of at least some of the information passing between the remote units and the user equipment. The controller is separated from the remote units by an intermediate network. The controllers or controller resources are configured to obtain information about data capacity demands in different areas of the site, and to configure one or more communication cells in the different areas of the site based on the information about data capacity demands in order to accommodate the data capacity demands, wherein the one or more communication cells are configured by changing assignments of a number of the remote units with a number of the controllers or controller resources.

    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: One embodiment is used in a scalable cloud environment configured to implement a plurality of virtualized entities that implement a part of a base station to provide wireless service to user equipment. The plurality of virtualized entities comprises first and second virtualized entities. Processing performed by the first virtualized entity generates data that is used by processing performed by the second virtualized entity. Cloud native software included in the scalable cloud environment is configured to collect cloud-native metrics associated with implementing the second virtualized entity in the scalable cloud environment. The existence of a congestion condition for the second virtualized entity can be determined based on the cloud-native metrics collected for the second virtualized entity and, in response to determining that the congestion condition exists for the second virtualized entity, a control action can be taken in order to throttle the first virtualized entity.
