Abstract: Methods and apparatus for enhancing performance of a wireline communication network backhaul for wireless nodes based on data traffic and node characterization. In one embodiment, the node comprises a small-cell or other wireless base station (e.g., one utilizing unlicensed or quasi-licensed spectrum such as CBRS or C-Band) that is backhauled by a DOCSIS system within a managed HFC network, and the methods and apparatus utilize such factors as traffic load, geographic or topological location, node technology type, and user device profile for each node to determine scheduling of traffic over the wireline transmission medium used for the delivery of services. In another embodiment, the foregoing factors can be weighted for further determination related to an assignment of the time slots or other resources for the delivery of services.

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: A first dual SIM user equipment (UE) has a first wireless connection to first Citizens Broadband radio Services Devices (CBSD) of a first network and a second wireless connection to a second CBSD of a second network. Different encryption and different frequency hopping patterns are used with regard to communicating the same voice packet information over the first and second wireless connections. The same voice information is attempted to be redundantly communicated over the two connections, e.g. concurrently or with a slight delay with regard to the two connections. The CBRS communications are typically less reliable than cellular licensed spectrum communications, and a particular encrypted voice packet may, and sometimes is lost; however, the redundancy is used to compensate for expected losses. Successfully recovered encrypted voice packets are sent from the CBSDs to a packet synchronizer which performs decryption and combines the recovered packets into a single packet stream.

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: Dynamic data rate selection in wireless networks is described. The includes sending, by a wireless controller to a base station, an access point power-data rate table. The base station updates a base station power-data rate table with the access point power-data rate table based on checking defined thresholds, confirms the validity of the updated base station power-data rate table by receiving measurements from a user device responsive to communications using the updated base station power-data rate table, reverts to a previous base station power-data rate table if the measurements indicate that the updated base station power-data rate table is not correct, and sends to the wireless controller one of the updated base station power-data rate table or the previous base station power-data rate table. The wireless controller updates the access point power-data rate table and sends the updated access point power-data rate table to an access point.
