Abstract: Methods and apparatus for managing system information message transmission in a distribution network (e.g., a wireless network such as one compliant with 3GPP 5G NR-U). In one embodiment, transmission of multiple SI (System Information) messages with overlapping SI-windows is enabled but with no soft-combining support. In another embodiment, transmission of multiple SI-messages with overlapping SI-windows is enabled with soft-combining support. In yet another embodiment, aperiodic OSI transmission is enabled. Moreover, the present disclosure provides mechanisms for notifying UE of an SI change.

Abstract: A data driven spectrum sharing approach is implemented amongst users of a shared band. A spectrum access controller (SAC) estimates interference and allocates spectrum in one or more bands to a plurality of spectrum user devices, e.g., macro base stations, small cell base stations, access points, etc. Different spectrum user devices in the plurality of spectrum user devices may correspond to different service providers, may use different technologies, may use different communications protocols, and/or may have different transmission power levels. The spectrum user devices send data feedback reports to the SAC including, e.g., received signals strength information, signal quality information, interference information, etc. The SAC uses the received data feedback reports to adjust, e.g., fine tune, interference limits and/or propagation model parameters. The SAC uses the adjusted, e.g., refined, interference limits and adjusted, e.g., refined propagation models, to make more accurate decisions regarding spectrum reuse.

Abstract: Methods and apparatus for predicting communications resources which will be needed at a venue and then controlling the amount of available resources dynamically are described. In various embodiments real time or near real time video of areas of the venue are used to predict the number of people in a portion of a venue and/or the direction of movement. Along with other information such as the type of event and/or event schedule collected information is supplied to a set of trained resource requirement models which are used to predict future resource needs at a venue, e.g., while an event is ongoing. Commands are sent to dynamically vary the amount of communications resources provided to one or more portions of the venue. Resources which can be varied included but are not limited to fixed wired WAN bandwidth, WiFi bandwidth, cellular bandwidth, network based on-demand services, transcoding services, firewall services, etc.

Abstract: Methods and systems for automatically optimizing power utilization in a network. A method for automatically optimizing power utilization in a network includes obtaining, by a network controller from a database, systems provisioned in the network, wherein a system includes one or more actionable components and wherein the systems and associated one or more actionable components are actional elements, obtaining predictive traffic model statistics for a circuit under evaluation, wherein the circuit transits between at least two systems of the systems in the network, obtaining real-time traffic statistics for the circuit under evaluation; and disabling, by the network controller when the real-time traffic model statistics are within a threshold of the predictive traffic model statistics, one or more actional elements to optimize power utilization while factoring in fate sharing dependencies associated with the one or more actional elements and while maintaining minimum utilization requirements of the network.

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 supporting wireless medium sharing in wireless communications systems, e.g., various 802.11 wireless communications systems, are described. A novel shared transmission type of trigger frame is implemented, which allows a wireless station, acting as a host station, to make available transmission resources, which have been acquired by the wireless station, to one or more guest stations. A shared transmission type of trigger frame, generated and transmitted by the host station communicates information identifying the attributes of a corresponding trigger based (TB) frame, information identifying resources of the TB frame to be used by the host station and information identifying one or more set of shared resources which may be used by guest station(s). The trigger based (TB) frame, corresponding to the transmitted shared transmission type trigger frame, is used by the host station and one or more guest stations to transmit data to an access point.

Abstract: A radio frequency (RF) amplifier assembly includes modular amplification and processing units, which can be easily installed or replaced in the housing of the RF amplifier assembly, e.g., in response to changing needs and/or changing capabilities in the cable network communications system. The RF amplifier housing facilitates, e.g., via slots with connectors, accepting and coupling of alternative modular units, which can be installed/removed. The RF amplifier assembly includes a first spectrum (e.g., legacy spectrum) amplification and processing circuit, supporting both upstream and downstream signaling. The RF amplification assembly further includes one or more optional additional (extended) spectrum amplification and processing circuits, which are removeable modular units, and which support downstream signaling over extended spectrum. The RF amplifier assembly further includes spectrum splitter/combiner circuits, e.g., implemented in some embodiments using a diplexer-less design, for splitting/combining spectrum blocks with regard to multiple amplification and processing circuits installed within the RF amplifier assembly.
