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 central unit is configured to determine sets of data to be sent to a plurality of remote units across the fronthaul interface. The central unit is also configured to determine a mapping of each of the sets of data to at least one of the plurality of remote units. The central unit is also configured to add a respective indicator, based on the mapping, to each set of data, wherein each respective indicator indicates each remote unit that the respective set of data is intended for. The central unit is also configured to broadcast the sets of data, each with the respective indicator, to the plurality of remote units.

Abstract: Some embodiments are directed to systems and methods for performing automatic transmit power control for a subset of radio points of a centralized radio access network (C-RAN) deployed in a venue (such as a stadium or arena) that are mounted in or near the venue so as to primarily provide wireless coverage to user equipment located in the event area of the venue.

Abstract: This disclosure relates to Multi-User Multiple-Input-Multiple-Output (MU-MIMO) (including without limitation Distributed MU-MIMO (D-MU-MIMO)) communication techniques that employ interference suppression (IS) precoding schemes (including, for example, precoding schemes that use local interference suppression and precoding schemes that use global interreference suppression).

Abstract: An example communication system in a cellular network comprises: a processing system comprising a controller and remote units, with the remote units being configured to communicate with the controller and to communicate with mobile devices within a communication cell of the cellular network. At least part of the processing system is configured to perform operations comprising: estimating signal strength experienced by all or some of the mobile devices; identifying, based at least on the signal strength, one or more of the mobile devices that can be scheduled for communication with one or more of the remote units in the communication cell on a same airlink resource; and scheduling the communication.
