Abstract: A communication system includes a receive antenna for receiving communication signals, processing circuitry for processing the received communication signals and repeating the signals for further transmission and at least one transmit antenna for transmitting the repeated signals. The processing circuitry utilizes configurable settings for controlling the operation of the communication system and the configurable settings are variable for varying the operation of the system. The processing circuitry is further operable for receiving inputs regarding current operating conditions of the communication system and for selectively adapting the configurable settings of the system based upon the operating condition inputs.

Abstract: Telecommunication systems using multiple Nyquist zone operations are provided. In one aspect, a telecommunication system can include a first section and a second section. The first section can receive signals from at least one transmitting base station or transmitting terminal device. The received signals have frequencies in multiple frequency bands. The first section can also sample the received signals such that the received signals are aliased. The first section can also combine the aliased signals from the frequency bands into a combined frequency band in a common Nyquist zone. The second section can extract signals from the combined frequency band. The extracted signals are to be transmitted at frequencies in a frequency band from a Nyquist zone that is different than the common Nyquist zone. The second section can also transmit the extracted signals to at least one receiving base station or receiving terminal device. Other embodiments are disclosed.

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: One embodiment is directed to a repeater system configured for use with a base station that implements a wireless interface that makes use of control transmissions that are retransmittable (for example, LTE PRACH transmissions). The repeater system implements a simplified mute or squelch function that transitions the repeater circuitry from a muted state to an unmuted state in response to a received power level crossing a first threshold value in connection with a first control transmission. Although that first control transmission will be lost, the repeater circuitry is configured to remain in the unmuted state in order to handle a retransmitted control transmission and to handle any associated subsequent control and user transmissions. The repeater system can be implemented as a single-node repeater and/or a distributed antenna system. Other embodiments are disclosed.
