Abstract: Methods and apparatus for determining and adjusting subcarrier spacing (SCS) to be used by a base station, e.g., a CBSD, for transmitting downlink data to one or more wireless devices, e.g., UEs, are described. A subcarrier spacing (SCS) level to be used by the base station is determined based on information relating to buffering of downlink data supplied to the base station via a cable, e.g., data accumulation rate (DAR) and/or average data arrival time (ADAT). Measured cable modem (CM) to base station latency is also used in the SCS determination. The amount of time for which a determined SCS level is to be used by the base station is set based on measured latency between a CMTS and the CM.

Abstract: Methods and systems for citizens broadband radio service (CBRS) device (CBSD) interference management is described. A method for managing shared spectrum network interference includes determining, by a Citizens Broadband Radio Service (CBRS) device (CBSD) granted shared spectrum by a spectrum access system (SAS), a number of mobile devices in a defined number of regions in a cell covered by the CBSD, assigning, by the CBSD, a greater number of antennas to a cell edge region from the defined number of regions than a remaining regions in the defined number of regions, and assigning, by the CBSD, at least 8 antennas to each mobile device of a defined number of mobile devices of the number of mobile devices in the cell edge region to transmit non-overlapping and directive beams to mitigate interference at the cell edge region.

Abstract: A communication system includes a first wireless base station supporting communications with multiple mobile communication devices. The first wireless base station is limited to an amount of power it is able to consume. For example, the wireless base station receives power consumption information from a power consumption manager. To control power consumption with respect to the received power consumption information, the wireless base station determines (such as based on an estimation, calculation, measurement, etc.), an amount of a power consumption by the wireless base station while communicating with multiple mobile communication devices. The wireless base station adjusts wireless communications transmitted from the wireless base station to maintain the power consumption of the wireless base station with respect to a power consumption limit as indicated by the received power consumption information.

Abstract: Methods and apparatus for increasing channel diversity in a MIMO system, e.g. a massive MIMO system, are described. Some selected sounding reference signal values are applied to control base station transmission for antennas, e.g., randomly or semi-randomly selected antennas, to which they do not actually correspond. The wireless terminal perceives this change as a change in channel conditions, which is subsequently reported in channel status information (CSI) to the base station. This results in increased channel diversity, which is beneficial to the base station scheduler.

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.

Abstract: Methods and apparatus for using a first number of antennas at one base station, e.g., at a first CBSD, in combination with a second, e.g., lesser number of antennas at another base station to provide different wireless terminals communications channels with different channel conditions are described. A ‘relay mode’ of operation at the second base station facilitates communication of data from the first base station. In this way the second base station is used to relay data sent from the first base station while the UE perceives the data as having been sent over the air by the first base station. The channels from the first and second base stations operate together providing a composite channel that will have different channel conditions than would be possible using simply the antennas of the first base station. Differences in channels to different UEs facilitates transmission scheduling at the first base station.

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 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: 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.
