Abstract: One embodiment is directed to an open radio access network to provide wireless coverage for a plurality of cells at a site and that comprises a virtualized headend comprising one or more base-station nodes and a plurality of unified remote units deployed at the site. Each of the unified remote units is able to support multiple functional splits, multiple wireless interface protocols, multiple generations of radio access technology, and multiple frequency bands. The unified remote units and functional split used to serve each cell can be changed (for example, on-the-fly as a part of an automatic or manual adaptation process that is a function of one or more monitored performance attributes of the open radio access network such as network bandwidth, network latency, processing load, or processing performance). The unified remote units can be implemented in a modular manner with a backplane to which different radio modules can be coupled.

Abstract: In an embodiment, a remote antenna unit includes a transmitter, a receiver, an antenna, a first interference circuit, and a second interference circuit. The transmitter is configured to generate a transmit signal, and the receiver configured to process a receive signal. The antenna is coupled to the transmitter and the receiver and is configured to radiate a downlink signal in response to the transmit signal and generate the receive signal in response to an uplink signal. The first interference circuit is coupled to the transmitter and the receiver and is configured to receive an analog signal from the transmitter. The second interference circuit coupled to the transmitter and the receiver. The first interference circuit and the second interference circuit are configured to reduce, in the receive signal, interference caused by the transmit signal and/or at least one downlink signal radiated by an antenna.

Abstract: A communication system includes master host unit, hybrid expansion unit, and remote antenna unit. Master host unit communicates analog signals with service provider interfaces. Master host unit and hybrid expansion unit communicate N-bit words of digitized spectrum over communication link. Hybrid expansion unit converts between N-bit words and analog spectrum. Hybrid expansion unit and remote antenna unit communicate analog spectrum over analog communication medium. Remote antenna unit transmits and receives wireless signals over air interfaces. Master host unit includes master clock distribution unit that generates digital master reference clock signal. Master host unit communicates digital master reference clock signal over communication link. Hybrid expansion unit receives digital master reference clock signal from master host unit over communication link and generates analog reference clock signal based on digital master reference clock signal. Hybrid expansion unit sends, and remote antenna unit receives, analog reference clock signal across analog communication medium.

Abstract: A method for measuring downlink delay in a radio system includes applying a digital representation of a Gaussian pulse to a digital interface of the radio system; marking the digital representation of the Gaussian pulse with respect to a frame of digital data with a marker; propagating the Gaussian pulse in the radio system to an antenna, the radio system configured to convert the digital representation of the Gaussian pulse to a radio frequency signal transmitted at the antenna; measuring when the Gaussian pulse occurs in the radio frequency signal based on the marker; and determining a downlink propagation delay for the radio system between application of the digital representation of the Gaussian pulse at the digital interface and transmission of the radio frequency signal at the antenna.

Digital data stream includes first and second digital data derived from first and second base station. First and second digital data comprises first and second digital values associated with respective time periods. Summing unit extracts first digital data from digital data stream. Summer function digitally sums first digital data with third digital data derived from third base station to generate summed digital data for conversion to radio frequency signals and transmission at antenna. Third digital data comprises third series of third digital values associated with respective time periods. Summer function digitally sums first digital data with third digital data by digitally summing (i) first digital value associated with respective time period and (ii) third digital value associated with respective time period to produce summed value for respective time period.
