Abstract: Methods and apparatus for access node selection, and optimization of antenna direction and performance, within a power-limited system. In one embodiment, the system utilizes “quasi-licensed” CBRS (Citizens Broadband Radio Service) wireless spectrum in conjunction with a controller that dynamically adjusts antenna direction for receiving/transmitting information at an installed fixed wireless apparatus (FWA) at user or subscriber premises. In one variant, the FWA receives data on candidate access nodes (CBSDs), and includes controller logic that compares received power levels for candidate access nodes with the power levels estimated from path loss models, and optimizes antenna azimuth to maximize the antenna gain towards the selected access nodes. As such, service calls to optimize antenna performance after initial installation are not required, and network operating expenses are thereby reduced. Dynamic node reselection and optimization may also be used in instances of CBSD/spectrum withdrawal, changes in physical environment, and other applications.

Abstract: Methods and apparatus for managing capacity in a Citizens Broadband Radio Service (CBRS) network. An exemplary method embodiment includes operating a Citizens Broadband Radio Service Device (CBSD) of a cell to perform the steps of: receiving a power down message; decreasing, in response to the power down message, UE inactivity timer length for one or more UEs from a first length to a second length; and continuing to transmit packets to UEs at an edge of the cell. An exemplary system embodiment includes: a CBSD of a cell that comprises: a network receiver that receives a power down message; a first processor that controls the first CBSD to decrease, in response to the power down message, UE inactivity timer length for one or more UEs from a first length to a second length; and a wireless transmitter that continues to transmit packets to UEs at an edge of the cell.

Abstract: Methods, systems and apparatus for allocating frequency spectrum resources in a Citizens Broadband Radio Service network. An exemplary method embodiment includes the steps of: receiving, by a Spectrum Access System (SAS), a channel message from a Citizens Broadband Radio Service Device (CBSD); selecting, by the SAS, in response to the received channel allocation message, a first frequency spectrum channel from a plurality of available frequency spectrum channels based on a type of traffic the CBSD is carrying; assigning, by the SAS, the selected first frequency spectrum channel to the CBSD for use in wireless communications with user equipment devices; communicating, by the SAS, information identifying the assigned first frequency spectrum channel to the CBSD. When the determined type of traffic being carried by the CBSD is said uplink dominated traffic basing said first frequency spectrum channel selection on adjacent channel interference.

Abstract: A subscriber identification module (SIM) level task scheduler is described. A dual SIM device SIM radio controller determines quality of service (QoS) levels for each service running on a dual SIM device. A first SIM and radio are connected to one of an unlicensed spectrum network or a licensed spectrum network, which are operated by a same service provider. A second SIM and radio scan for available network connections operated by the service provider. The dual SIM device measures QoS levels and the controller checks them against QoS requirements. The controller instructs the second radio to connect to a selected network from the available networks when the measured QoS levels are at least steadily degrading. The dual SIM device shares and negotiates the first radio settings with the selected network. The controller instructs a processor to switch from the first to the second radio when the selected network is ready.
