Abstract: Methods and apparatus for estimating a Citizens Broadband Radio Service Device's (CBSD's) coverage area using user equipment (UE) timing advance and/or power headroom information and allocating resources based on the estimate. In an exemplary method embodiment a Spectrum Access System: (i) receives, from a CBSD, user equipment (UE) information including at least one of timing advance or power headroom information for one or more UEs in communication with the CBSD; (ii) estimates, based on the received first UE information, a first CBSD coverage area; and (iii) makes a first resource allocation to the CBSD based on the estimated CBSD coverage area, the first resource allocation including an allocation of at least one of a frequency bandwidth allocation or transmission power allocation to the CBSD.

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.

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 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 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: Methods and apparatus for enhancing communication and performance 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 communication between the small cell/base station and the backhaul network so as to support “rate matching” between the device to mitigate packet overflow or other issues. In one implementation, enhanced cable modem (CM) and base station devices coordinate to inform the base station of the modulation order (and/or other parameters related to transmission of the data destined for the base station on the backhaul) so that the base station can selectively invoke utilization of higher-order modulation and/or coding schemes, as well as spatial multiplexing or beamforming.

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.

Abstract: A mobile network operator (MNO) base station, e.g., an eNB, instructs a mobile virtual network operator (MVNO) user equipment (UE) to monitor to detect signals from base stations in its MVNO network and to report back the results. If the UE reports to the MNO base station, that it has detected signals from base stations, e.g. CBSDs, in its MVNO, the MNO base station applies one or more rules included in a stored Service Profile Identifier, corresponding to the UE, the applying of the one or more rules causes the MNO base station to disconnect or deny service to the UE. Alternatively, when it is determined that the UE did not detect a signal from a base station, e.g. a CBSD, in its MVNO, then the MNO base station provides communications service to the UE.
