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.

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: Methods and apparatus for prioritizing data traffic in small-cell wireless system. In one embodiment, the system utilizes “quasi-licensed” CBRS (Citizens Broadband Radio Service) wireless spectrum in conjunction with a wireless communication network (e.g., 3GPP 4G-LTE or 5G-NR-based). A “traffic profile” message is used to prioritize the data traffic. In one variant, the traffic profile message is generated by a Customer Premises Equipment (CPE) such as a CBRS FWA, and includes data related to CPE identification, default bearer identification, number of client devices served by the CPE (e.g., via a wireless router connected to the CPE), traffic type and/or priority level associated with each client device and/or data traffic type, etc. In another variant, the base station provides data services to a plurality of fixed wireless access (FWA) apparatus installed at user or subscriber premises of a network based on prioritization according to the present disclosure.

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.
