摘要： Apparatus and methods for multi-mode operation of a wireless-enabled device, including for extending the range of the wireless signal in a wireless network. In one embodiment, a multi-mode Consumer Premises Equipment (CPE) is provided utilizing “quasi-licensed” CBRS (Citizen Broadband Radio Service) wireless spectrum. In one variant, the apparatus and methods provide a solution to use a CPE in a Wi-Fi extender mode to extend Wi-Fi signal from a router. In another variant, a solution is provided to use a CPE in an LTE repeater mode to extend the LTE signal from an LTE eNB/gNB. In another embodiment, a CPE is used as a base station for a wireless network utilizing “quasi-licensed” CBRS (Citizen Broadband Radio Service) wireless spectrum.

摘要： Methods, apparatus, and systems for using multiple antennas located in Citizens Broadcast Radio Service Devices (CBSDs) to communicate with a user equipment device. An exemplary method embodiment includes the steps of: (i) receiving by a macro base station a first set of data to be transmitted to a user equipment device (UE), (iii) dividing by the macro base station said first set of data into a plurality of N data blocks, and (iv) communicating by the macro base station to each of a plurality of different Citizens Broadband Radio Service Devices (CBSDs) one or more different ones of said plurality of N data blocks; and (v) operating the plurality of CBSDs to transmit the one or more data blocks which they receive from the macro base station to the UE. In various embodiments, the macro base station also transmits one or more of the N data blocks to the UE.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
