Abstract: Various embodiments comprise systems, methods, architectures, mechanisms and apparatus for allocating resources in a converged network to support, illustratively, Long Term Evolution (LTE) Licensed Assisted Access (LAA) transmission for supplemental downlink mode. Various embodiments contemplate allowing LTE eNBs having CBSD capability to use spectrum normally associated with a wireless access point (WAP) if such spectrum can be made available based on, for example, WiFi spectrum or channel measurements of interference such as provided by UE proximate the WAP and connected to the CBSD.

Abstract: Methods and apparatus for managing spectrum in a CBRS network to provide services to user equipment devices located at a customer's premises. In various embodiments, the customer premises has no landline connection. An exemplary method embodiment includes the steps of: receiving, by the CBRS CPE base station, over the air from each of a plurality of Citizens Broadband Radio Service Fixed Wireless Access (CBRS FWA) tower base stations a reference signal; selecting, based on the strength of each of the received reference signals, a primary CBRS FWA tower base station from the plurality of CBRS FWA tower base stations; establishing, by the CBRS CPE base station, a wireless communications link connection with the CBRS FWA tower base station selected as the primary CBRS FWA tower base station; reserving, by the CBRS CPE base station, an amount of spectrum for communicating with one or more auxiliary CBRS FWA tower base stations.

Abstract: A base station, e.g., a CBSD, selects or more user equipment (UE) devices, e.g., cell phones, to operate in monitoring mode. In monitoring mode the UE device, in addition to its normal communications with the base station, performs received power measurements in a frequency band, e.g., a CBRS band. The UE reports to the base station information indicating a UE determined measured power level attributed to incumbent user or measurement information used to derive a power level attributed to incumbent user. One or more base stations report received power measurement values attributed to incumbent user to a system management device, e.g., a SAS. The system management device processes the received information, e.g. combining information, and comparing a result to a threshold level. If the result exceeds the threshold the system management device sends a command to one or more base station to shut down DL traffic in the CBRS band.

Abstract: Various embodiments comprise systems, methods, architectures, mechanisms and apparatus for creating coverage zones (CZs) at a Citizens Broadband Radio Service Device (CBSD) nodes where each CZ is defined by a respective Physical layer Cell Identity (PCI), and each CZ is allocated a respective time slot having a duration selected in accordance with a type of wireless device (WD) to be supported by the CZ, and each CZ communicates during its respective time slot via some or all of the antennas or antenna sections (e.g., coverage areas or sections S1-S3) of the node such that the node communicates with different types of WD in a time-interleaved manner via some or all of the coverage areas associated with the node.

Abstract: Methods and apparatus for enhancing connectivity for a device backhauled by a wireline communication network. In one embodiment, the device comprises a small-cell or other wireless base station that is backhauled by a DOCSIS system within a managed HFC network, and the method and apparatus enable enhanced connection of user devices serviced by the base station (such as 3GPP UE or CBRS FWA) to a core entity for e.g., authentication and packet session establishment. In one implementation, enhanced Cable Termination System (CMTS) and cable modem (CM) devices coordinate to allocate prioritized service flows to traffic sourced from the base station. These service flows can selectively bypass extant DOCSIS protocols which might otherwise increase connection latency (including connection failure) such as AQM (active queue management) and packet dropping algorithms. In some variants, upstream service flow data rates can also be enhanced through temporary utilization of higher-order modulation and/or coding schemes.

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.

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: Apparatus and methods for providing multi-tier quasi-licensed spectrum wireless service via a common wireless access node such as a small-cell. In one embodiment, the quasi-licensed system utilizes multi-sector antennae to create antenna lobes adaptively according to parameters associated with different cell sectors, such as user traffic, random access requests, and/or interference. In one variant, when the user traffic or interference is determined to be very high in a particular sector, the sector is configured and activated based on the availability of low-noise spectrum. In another variant, when a new sector is created, the electrical power resources available for that sector are checked, and based on the amount of power available at that sector, either CBSD Category A or B status is allocated to that sector.

Abstract: Apparatus and methods for providing enhanced coverage in a quasi-licensed wireless system using a reduced-cost base station apparatus. In one embodiment, the base station is configured to utilize quasi-licensed 3.55-3.70 GHz CBRS (Citizens Broadband Radio Service) GAA and PAL spectrum, and employs a power amplifier sharing arrangement in its transmitter chain(s), along with multi-sector antenna elements. A scheduling algorithm operative on the base station generates sector-specific weights which are used to allocate the shared power amplifier(s) between the different sectors. Advantageously, design and production costs of the base station are reduced through sharing of comparatively expensive amplifier and transmitter chain components, thereby allowing for commoditization of the base station for mass distribution.
