Abstract: Systems and methods for dynamic base station functional split configuration management are provided. In one embodiment, a system for base station functional split management for uplink fronthaul traffic comprises: a baseband controller coupled to a plurality of radio units via a fronthaul network, wherein the plurality of radio units comprise a signal zone from which uplink signals are combined by the base station: a split controller configured to dynamically select and control a functional split of a respective uplink receive chain between the baseband controller and each of the plurality of radio units: wherein the functional split defines a demarcation point on the receive chain prior to which processing operations are executed by a radio unit and after which processing operations are executed by the baseband controller: wherein the split controller selects between a plurality of functional split options to dynamically control the functional split and the demarcation point.

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.
