Abstract: One embodiment of the disclosure relates to radio frequency (RF) communication channel reconfiguration in remote antenna unit (RAU) coverage areas in a distributed antenna system (DAS) to reduce RF interferences. In this regard, a spectrum optimization unit dynamically reconfigures RF communication channels employed by RAU coverage areas in a DAS to reduce or avoid adjacent-channel and/or co-channel RF interferences. Each of the RAU coverage areas provides a respective sniffed RF signal to the spectrum optimization unit. The spectrum optimization unit analyzes the respective sniffed RF signal to determine a respective lesser-interfered RF communication channel for an RAU coverage area and dynamically reconfigures the RAU coverage area to communicate on the respective lesser-interfered RF communication channel.

Abstract: Digital wireless distributed communications systems (WDCS) employing a centralized spectrum chunk construction of communications channels for distribution to remote units are disclosed. Individual, discrete communications channels received from one or more signal sources are centrally constructed into spectrum chunks before being distributed to remote units. When the communications channels are constructed into spectrum chunks, the individual communications channels are positioned in their respective defined center radio frequency (RF) frequencies of their respective communications band before being distributed to the remote units. Thus, the remote units do not have to include the additional cost and associated power consumption of processing circuitry to construct the communications bands for individual communications channels.

In this regard, a protocols division routing circuit(s) is provided in the WDS and configured to partition the time-division-based communications link between multiple types of communications signals based on a link configuration ratio.

Abstract: Channel-based remote unit monitoring and optimization in a wireless communications system (WCS) is described herein. A remote unit control circuit receives a number of communications signals each uniquely associated with a signal channel and a remote unit communicating on the signal channel. The communications signals are received by the remote unit control circuit before being recombined based on signal sources. The communications signals may be analyzed to determine key performance indicators (KPIs) for a selected signal channel (s) and/or a selected remote unit (s). The KPIs may be used to optimize performance of the WCS on a per signal channel and/or per remote unit basis. By employing the remote unit control circuit to determining the KPIs based on a selected signal channel (s) and/or a selected remote unit (s), it is possible to support channel-based remote unit monitoring and optimization in the WCS, thus helping to provide optimized user experience in the WCS.

Abstract: A gain control circuit in a wireless distribution system (WDS) is provided. The gain control circuit generates a combined digital communications signal based on a number of received radio frequency (RF) communications signals. The combined digital communications signal has a digital amplitude(s) representing a summed analog power level(s) of the RF communications signals in a predefined number of binary bits. When the summed analog power level(s) exceeds a maximum analog power level represented by the digital amplitude(s) in the predefined number of binary bits, the gain control circuit determines a selected RF communications signal(s) causing the summed analog power level to exceed the maximum analog power level and attenuates the selected RF communications signal(s) to reduce the summed analog power level to below the maximum analog power level. As such, it is possible to achieve a calculated balance between performance, complexity, and cost in the gain control circuit.

In this manner, radio resources for servicing non-ICIC-engaged remote units are not divided among non-ICIC-engaged remote units.

Abstract: Embodiments of the disclosure relate to allocating digital channels into spectrum chunks in a wireless distribution system (WDS). In a WDS, a central unit is configured to communicate downlink and uplink communications signals with a plurality of remote units over a plurality of downlink and uplink communication links.

To avoid a single point of failure in reference signal generation that could cause components relying on the reference signal to not operate properly, the reference signal generation circuits disclosed herein include a plurality of reference signal generation modules. One reference signal generation module is configured as the master reference signal generation module to generate a master reference signal distributed in the wireless communication system. The other reference signal generation modules are configured as slave reference signal generation modules. If a failure is detected in the generation of the master reference signal in the master reference signal generation module, another slave reference signal generation module is reconfigured to be the new master reference signal generation module to generate the master reference signal.

Abstract: Embodiments disclosed in the detailed description include supporting an add-on remote unit(s) (RU) in an optical fiber-based distributed antenna system (DAS) over existing optical fiber communications medium using radio frequency (RF) multiplexing. An existing DAS comprises at least one existing head end equipment (HEE) communicatively coupled to a plurality of existing RUs through an existing optical fiber communications medium. In aspects disclosed herein, an add-on RU is added to the existing DAS to support additional wireless communications. No new optical fibers are required to be deployed to support communications to the add-on RU in the existing DAS. Instead, the existing DAS is configured to support the add-on RU through the existing optical fiber communications medium using RF multiplexing. As a result, the add-on RU can be added to the existing optical fiber-based DAS without adding new optical fibers, thus leading to reduced service disruptions and deployment costs.
