Publication number: 20240121145Abstract: To provide improvements in crest factor reduction in a distributed communication system, CFR configuration parameters can be determined based on communication signals received from a base station entity and distributed to node(s) of the distributed communication system. CFR engine(s) in the node(s) may perform CFR based on the CFR configuration parameters, and/or may adjust their CFR engine(s) based on signal parameters and/or operating parameters of a power amplifier coupled to a respective CFR engine. Some or all CFR processing may be offloaded from a node and assigned to optical transport card(s) of the system controller based on a processing bandwidth associated with the optical transport card(s).Type: ApplicationFiled: October 6, 2023Publication date: April 11, 2024Applicant: CommScope Technologies LLCInventors: Samuele Brighenti, Gabriele Moroni, Massimo Del Prete, Rainer Friedrich, Patrick Braun, Peter Schmid

Patent number: 10455510Abstract: Certain aspects involve an interface device for a distributed antenna system (“DAS”). In some aspects, the interface device can include an interface, a power detector, and a processor. The interface can include one or more ports for communicatively coupling the interface device to a base station and a switch that is switchable between first and second configurations. The first configuration connects a port to a downlink path of the DAS, and the second configuration connects the port to a signal reflection path. The processor can switch the switch between the first and second configurations based on a signal power measured by the power detector at the port. In other aspects, the interface device can include additional ports and termination loads. The processor can cause a signal path to be connected to a termination load instead of a port based on the port being disconnected from a unit of the DAS.Type: GrantFiled: December 29, 2017Date of Patent: October 22, 2019Assignee: Andrew Wireless Systems GmbHInventors: Massimiliano Mini, Stefan Eisenwinter, Samuele Brighenti, Enrico Maria Fabbri

Patent number: 10244507Abstract: Certain features relate to a centralized radio access network (C-RAN) that can flexibly and dynamically allocate protocol layer processing among baseband processing units and remote units. A C-RAN can be configured to include a media access control (“MAC”) scheduler and a fronthaul physical layer coordinator.
