    Abstract: Among other things, a communication system comprising remote units, a reference timing source, a controller, a controller clock, and a remote unit clock. The remote units exchange radio frequency (RF) signals with mobile devices. The reference timing source is synchronized with a coordinated universal time (UTC) or a Global Positioning System (GPS). The controller clock is synchronized with the reference timing source and provides timing information to the controller. The remote unit clock is synchronized with the controller clock and provides timing information to a remote unit. The controller and the remote unit are configured to transmit time stamp messages to synchronize the controller clock and the remote unit clock, by avoiding contention between time stamp transmissions and baseband data transmissions or between time stamp transmissions of different remote units to the controller.

    Abstract: One embodiment is directed to a system to provide wireless service to user equipment using licensed radio frequency spectrum and unlicensed RF spectrum. The system comprises a controller and a plurality of radio points to transmit and receive radio frequency signals to and from the user equipment using the licensed RF spectrum. The system further comprises a wireless termination to transmit and receive radio frequency signals to and from the user equipment using unlicensed RF spectrum. The controller is configured to use a mobility group for providing the wireless service to the user equipment using the unlicensed RF spectrum and a plurality of WLAN access points. The controller is configured to establish an interface with the wireless termination for the mobility group to communicate control plane data to the wireless termination associated with providing the wireless service to the user equipment using the unlicensed RF spectrum. Other embodiments are disclosed.

    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.

    Abstract: Among other things, a communication system comprising at least one remote unit and at least one controller is described. The at least one remote unit exchanges radio frequency (RF) signals with mobile devices. Each RF signal comprises information destined for, or originating from, at least one of the mobile devices. The at least one controller is communicatively coupled to the at least one remote unit. All physical layer processing for an air interface is implemented in the at least one remote unit. All Media Access Control (MAC) layer processing for the air interface is implemented in the at least one controller.

    Abstract: Among other things, a communication system comprising remote units and a controller is described. The remote units exchange radio frequency (RF) signals with mobile devices. At least some of the RF signals comprise information destined for, or originating from, a mobile device. The controller comprises one or more modems and is connected to an external network. At least one of the modems is a baseband modem and is 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 carried in frames between the controller and the remote units. The second data comprises baseband data and at least some of the baseband data is compressed in a frequency domain. The remote units and the controller are configured to compress the baseband data for transmission over the intermediate network.
