Abstract: 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).

Abstract: In one embodiment, a multi-transceiver RF signal processing system comprises: a controller; a DPD core and CFR engine; and a plurality of transceiver paths comprising at least a first transceiver path for a first frequency block, and a second transceiver path for a second frequency block. The first frequency block is adjacent to the second frequency block. Signal processing outputs a stream of digital RF based on wireless RF signals received into the first and second transceiver paths. Signal processing inputs a first stream of digital RF and outputs a first digital RF signal corresponding to the first frequency block to the first transceiver path, and outputs a second digital RF signal corresponding to the second frequency block to the second transceiver path for wireless transmission via the at least one antenna. The DPD core applies a distortion that covers the first and second frequency blocks.

Abstract: One embodiment is directed to a system to provide wireless coverage for a plurality of cells. The system comprises a virtualized headend and a plurality of remote units. The system is configured to operate as a distributed antenna system (DAS) when serving at least one of the cells. The plurality of remote units is configured to communicate with the virtualized headend using a switched Ethernet network. The virtualized headend is configured to communicate downlink user-plane data including frequency-domain IQ data and downlink control-plane data for a first cell served by at least one open radio access network (O-RAN) distributed unit (DU) to at least some of the remote units used to serve the first cell. At least some physical layer baseband processing for a wireless interface used to serve the first cell is performed by the virtualized headend or the remote units used to serve the first cell.

Abstract: Systems and methods for a modular access point are provided. In certain embodiments, a device includes a housing. Further, the device includes a baseband card (BBC) mounted within the housing, wherein the modular BBC has one or more interfaces. Additionally, the device includes one or more radio modules, wherein at least one radio module in the one or more radio modules is coupled to an interface in the one or more interfaces, wherein the one or more interfaces are capable of connecting to multiple different power classes of radio modules. Moreover, the device includes one or more additional components in communication with the modular BBC through the one or more interfaces that support the operation of a radio module in a respective power class.

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 one embodiment, a RF signal repeater switchable between SISO and MIMO comprises: a controller; a first transmitter path switchably coupled to first donor and coverage antennas; a second transmitter path switchably coupled to second donor and coverage antennas; a first receiver path switchably coupled to the first donor and coverage antennas; a second receiver path switchably coupled to the second donor and coverage antennas. The controller configures the repeater for a MIMO TDD operating mode by: configuring the first transmitter path and the second receiver path to repeat at least a first MIMO channel of UE uplink RF signals and at least a first MIMO channel of base station downlink RF signals; and configuring the second transmitter path and the first receiver path to repeat at least a second MIMO channel of UE uplink RF signals and at least a second MIMO channel of base station downlink RF signals.

Abstract: One embodiment is directed to a master unit for a distributed antenna system (DAS). The master unit comprises one or more donor cards and one or more transport cards, and at least one passive backplane. Each passive backplane comprises a plurality of backplane connectors. Each backplane connector is configured to connect a respective donor card or transport card to the passive backplane. Each backplane connector is connected to each of the other connectors via one or more respective passive bi-directional backplane channels. The master unit is configured so that all active processing of streams of digital samples transported via the DAS is performed by the donor cards and transport cards and not the passive backplane.
