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: 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: 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.
