Abstract: Methods and apparatus for enhancing performance of a wireline communication network backhaul for a wireless node. In one embodiment, the node comprises a small-cell or other wireless base station that is backhauled by a DOCSIS system within a managed HFC network, and the methods and apparatus enable enhanced communication between the small cell/base station and the backhaul network so as to support adaptation by the wireline network for frequencies used by the node so as to mitigate interference or other issues. In one implementation, enhanced cable modem (CM), cable modem termination system (CMTS) and node devices coordinate to inform the CMTS of use of potentially interfering frequencies by the base station so that the CMTS can monitor, and reconfigure as necessary, any affected wireline RF channels.

Abstract: Methods and systems for citizens broadband radio service (CBRS) interference management using dual subscriber identification module (SIM) devices are described. The method includes assigning a physical cell identity (PCI) to each CBRS device (CBSD) granted unlicensed spectrum by a spectrum access system (SAS). Each spectrum granted CBSD may exchange PCIs with neighbor spectrum granted CBSDs to resolve PCIs and maintains a PCI table. A dual SIM device may be connected to a CBSD via a first SIM. Each spectrum granted CBSD having a connected dual SIM device reports a number of PCIs detected by the dual SIM device(s). A SAS designated dual SIM device may use a second SIM to measure power values of PCIs detected by the designated dual SIM device which are absent from a provided PCI table. The measured power values may be used by the SAS to make cluster interference decisions.

Abstract: Methods and apparatus for enhancing packet scheduler fairness in a small-cell wireless communication network. In one embodiment, the methods and apparatus utilize “quasi-licensed” CBRS (Citizens Broadband Radio Service) wireless spectrum in conjunction with 3GPP wireless communication network (e.g. 4G LTE or 5GNR) for the delivery of services to a number of enhanced CPE (consumer premises equipment), such as fixed wireless apparatus (FWAe). The various FWAe report Channel Quality Indicator (CQI) data to their respective serving base stations over time, and each base station both builds a statistical characterization of each FWAe, and maps the CQI data to a prescribed configuration (e.g., to the Modulation and Coding Scheme (MCS)) adaptively for the transmission of the data to the FWAe, and development of a scheduler priority for each FWAe. In one implementation, once the CQI values are stable for a given FWAe, CQI reporting is terminated for a period of time.

Abstract: Methods and apparatus for enhancing data rates in a small-cell wireless communication network. In one embodiment, the methods and apparatus utilize “quasi-licensed” CBRS (Citizens Broadband Radio Service) wireless spectrum in conjunction with 3GPP wireless communication network (e.g. 4G LTE or 5GNR) for the delivery of services to a number of enhanced fixed wireless apparatus (CPEe/FWAe) at user or subscriber premises. The various CPEe/FWAe report Channel Quality Indicator (CQI) data to their respective serving base stations, and each base station maps the CQI value to a prescribed configuration (e.g., to the Modulation and Coding Scheme (MCS)) adaptively for the transmission of the data to the CPEe/FWAe. In one implementation, the base stations update the CQI to MCS values adaptively according to ACK/NACK requests received from the CPEe/FWAe.

Abstract: Apparatus and methods for providing interference management and load balancing in a wireless network. In one embodiment, the method and apparatus utilize quasi-licensed CBRS (Citizens Broadband Radio Service) wireless spectrum in conjunction with enhanced SAS (Spectrum Access System) and base station (e.g., CBSD) components to enable creation and management of virtual clusters of bases stations connected to the network, so as to enable inter-cluster interference mitigation, while also supporting load balancing between the base stations using coverage area overlap. In one implementation, the SAS reduces the coverage area (transmit power) of one or more base stations on a cluster edge to mitigate inter-cluster interference, and increases or adjusts the coverage of one or more base stations inside of the cluster to enable load balancing.
