    Abstract: Systems and methods for flexible antenna configurations and beamforming are provided. In one example, a system includes: at least one controller configured to implement at least some functions for one or more layers of a wireless interface used to communicate with UEs; remote unit(s) communicatively coupled to the at least one controller; and antenna elements communicatively coupled to the remote unit(s), each respective antenna element oriented in a respective direction different than other antenna elements. The at least one controller is configured to: determine a location of a UE in a cell of the system and/or channels between the antenna elements and the UE; select antenna element(s) for use in transmitting downlink signals to the UE based on the location of the UE and/or the channels between the antenna elements and the UE; and transmit downlink signals to the UE via the selected antenna element(s) in a first time period.

    Abstract: A communication system includes remote units, a UTC or GPS reference timing source, and a controller. The controller includes one or more modems and is connected to an external network, at least one of the modems being a baseband modem and being configured to pass first data corresponding to the information. The controller is separated from the remote units by an intermediate network over which second data corresponding to the information is transmitted in frames between the controller and the remote units. The second data includes baseband data. A controller clock is synchronized with the reference timing source and provides timing information to the controller. A remote unit clock is synchronized with the controller clock and provides timing information to a remote unit, the controller and the remote unit being configured to transmit time stamp messages to synchronize the controller clock and the remote unit clock.

    Abstract: In one embodiment, a method comprises determining which functional splits between processing performed in a baseband controller and processing performed in a remote unit are supported by each remote unit served by the baseband controller. The method further comprises determining at least one functional split in the processing performed in the baseband controller and the processing performed in the remote units to use. The method further comprises, for each said at least one functional split and each remote unit associated with that functional split, configuring the processing performed in the baseband controller and the processing performed in that remote unit are configured to use that functional split and configuring a respective interface between the baseband controller and that remote unit are configured for communicating front-haul data therebetween using that functional split.

    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.
