摘要： In one embodiment, an over-the-air millimeter wave repeater for a communications network comprises: a donor unit including a first plurality of modular electronic components and an access point including a second plurality of modular electronic components. The donor unit communicates downlink mmWave spectrum wireless signals received from a base station to the access point and radiates uplink mmWave spectrum wireless signals received from the access point to the base station. The access point radiates the downlink mmWave spectrum wireless signals received from the donor unit into a coverage area, receives the uplink mmWave spectrum wireless signals received from the coverage area, and communicates the uplink mmWave spectrum wireless signals to the donor unit. The first and second plurality of modular electronic components includes at least one of a modular antenna component, a modular signal conditioning component, a modular signal interface component, and a modular controller.

摘要： A frequency offset device can be located at a remote unit of a distributed antenna system and can be configured to combine two or more RF bands to allow the remote unit to process signals otherwise associated with a total RF bandwidth beyond the capabilities of the remote unit to process simultaneously. Signals of the RF bands are received at the unit. At least one of the RF bands is shifted to form a composite RF band that has an edge of a first RF band overlapping an edge of a second RF band. The composite RF band includes information from the signals of the first RF band and from the signals of the second RF band. The remote unit can process the composite RF band.

摘要： Certain aspects involve power management subsystems for a distributed antenna system ("DAS") or other telecommunication system. The power management subsystem can include a measurement module and an optimization module. The measurement module can monitor a utilization metric for a remote unit in the DAS or other telecommunication system. The power optimization module can determine whether the remote unit is underutilized based on the monitored utilization metric. The power optimization module can configure the remote unit for a low-power operation in response to determining that the remote unit is underutilized.

摘要： Certain features relate to operating a distributed antenna system or repeater system communicating frequency-division duplexing ("FDD") signals in a time-division duplexing ("TDD") mode. A TDD mode scheduler is configured for monitoring a downlink communications channel for the start of a downlink frame, sub-frame, or resource slot. Based on the start of a downlink frame, sub-frame, or resource slot, the TDD mode scheduler can identify a TDD transmission time-slot. The TDD mode scheduler can schedule high-powered downlink sub-frames during the TDD transmission time-slots where higher power output may be desirable. Based on the indication of the TDD transmission time-slot, a transmit/receive controller can increase the gain of the downlink communication and reduce the gain of the uplink communication.
摘要翻译：某些特征涉及操作以时分双工（“TDD”）模式传送频分双工（“FDD”）信号的分布式天线系统或中继器系统。 TDD模式调度器被配置为监视用于下行链路帧，子帧或资源时隙的开始的下行链路通信信道。基于下行链路帧，子帧或资源时隙的开始，TDD模式调度器可以识别TDD传输时隙。 TDD模式调度器可以在TDD传输时隙期间调度高功率下行链路子帧，其中可能需要较高功率输出。基于TDD传输时隙的指示，发送/接收控制器可以增加下行链路通信的增益并降低上行链路通信的增益。

摘要： 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.

摘要： Certain aspects and features of the present disclosure relate to a validation sub-system for determining whether access points in a telecommunication system provide suitable performance for a specified configuration of the telecommunication system. For example, a wireless receiver can simultaneous receive beacon signals at a common frequency from multiple access points. Each beacon signal has a data sequence that is different than the other beacon signals. A processing device can determine, based on the data sequences received by the wireless receiver, channel responses for channels between the access points and the wireless receiver. The processing device can output, based on the channel responses, an indicator that the access points are suitable for a specified configuration of a telecommunication system for providing wireless coverage using the access points.
