Abstract: A communication system includes a remote unit that exchanges radio frequency signals with mobile devices, at least some of the radio frequency signals comprising information destined for, or originating from, a mobile device, the remote unit being configured to perform first physical layer processing. A controller is separated from the remote unit by a switched Ethernet network, wherein data corresponding to the information is transmitted in frames between the controller and the remote unit. At least some of the data comprises baseband data that is transmitted in frequency domain. The controller and the remote unit are configured to transmit time stamp messages on the switched Ethernet network to synchronize a controller clock and a remote unit clock.

Abstract: One embodiment is directed to a system comprising a plurality of controllers and a plurality of radio points that provide wireless service to user equipment. The system is configured to serve a plurality of logical cells. The system is configured so that each logical cell is served by a respective group of the radio points. The system is configured to associate each group of radio points with a respective one or more controllers in order for the respective one or more controllers to serve the respective logical cell associated with that group of radio points while associated therewith. The system is configured to use a protection scheme in which the respective group of radio points that serves each logical cell does not change in the event of a fail-over that causes the one or more controllers associated with that group of radio points to change.

Abstract: One embodiment is directed to a multi-carrier radio point for use in a centralized radio access network (C-RAN). The multi-carrier radio point is configured so that the processing and hardware resources provided by the radio point can be associated with controllers of the C-RAN in a flexible manner. A single multi-carrier radio point can be used with multiple controllers to serve multiple cells, where the processing and hardware resources used for the multiple controllers need not be configured and used in the same way.
