Abstract: A communication system includes communication management hardware to control operation of first antenna hardware and second antenna hardware associated with a wireless base station. For example, in one arrangement, via control provided by the communication management hardware, the first antenna hardware transmits a first sidelobe wireless beam; the second antenna hardware transmits a second sidelobe wireless beam. The first sidelobe wireless beam and the second sidelobe wireless beam provide a communication device access to a remote network.

Abstract: Methods and apparatus for enhancing connectivity 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 connection of user devices serviced by the base station (such as 3GPP UE or CBRS FWA) to a core entity for e.g., authentication and packet session establishment. In one implementation, enhanced Cable Termination System (CMTS) and cable modem (CM) devices coordinate to allocate prioritized service flows to traffic sourced from the base station. These service flows can selectively bypass extant DOCSIS protocols which might otherwise increase connection latency (including connection failure) such as AQM (active queue management) and packet dropping algorithms. In some variants, upstream service flow data rates can also be enhanced through temporary utilization of higher-order modulation and/or coding schemes.

Abstract: A communication management resource detects or anticipates occurrence of wireless interference on a wireless channel allocated to a wireless base station to communicate with multiple communication devices. In response to the detected wireless interference, the communication management resource determines a group of the multiple communication devices receiving data of a particular type from the wireless base station. To reduce the wireless interference, the wireless base station notifies the communication devices in the group to operate in a device-to-device communication mode as an alternative path of conveying the particular type of data to the group of communication devices. Thus, during times of wireless interference, instead of communicating a message to each of the wireless communication device in the group, the wireless base station communicates a wireless communication to a first communication device in the group; the first communication device forwards the communication to a second communication device in the group.

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: Methods and apparatus for reducing base station downlink transmission power in a manner that provides one or more devices being serviced by the base station time to establish or switch to another connection are described. The methods and apparatus are particularly well suited for system where base stations may be instructed by a control device to reduce or stop downlink power to a point where downlink data transmission is not supportable. In various embodiments a base station responds to a downlink power reduction instruction by reducing downlink transmission power in downlink slots in a serious of power reduction steps. In cases where the required power reduction is to a point where downlink data transmission can not be supported, the base station signals that it is switching to a no DL slot mode of operation in which downlink slots are not supported but UL slots will continue to be supported.

Abstract: Dynamic data rate selection in wireless networks is described. The includes sending, by a wireless controller to a base station, an access point power-data rate table. The base station updates a base station power-data rate table with the access point power-data rate table based on checking defined thresholds, confirms the validity of the updated base station power-data rate table by receiving measurements from a user device responsive to communications using the updated base station power-data rate table, reverts to a previous base station power-data rate table if the measurements indicate that the updated base station power-data rate table is not correct, and sends to the wireless controller one of the updated base station power-data rate table or the previous base station power-data rate table. The wireless controller updates the access point power-data rate table and sends the updated access point power-data rate table to an access point.
