Abstract: Channel reuse may be used so that multiple networks may communicate via a shared powerline communication (PLC) medium. In a PLC network that supports different transmission modes, channel reuse may be improved by determining signal performance metrics associated with the different transmission modes. A transmission mode may be selected to facilitate channel reuse of the PLC medium by the local network and neighbor network. A first device and a second device may belong to a local network that shares the PLC medium with a neighbor network. The transmission mode may be selected based on interference and signal measurements at one or more receivers of the second device. The transmission mode may be selected from a group comprising a 2-stream multi-input multi-output (MIMO) eigen-beamforming transmission mode, a 1-stream MIMO spot-beamforming transmission mode, and a 1-stream single-input-single-output (SISO) transmission mode.

Abstract: A network device may be configured to adapt beamforming parameters for a communication region of a powerline cycle in response to variations in communication channel conditions. A first network device can estimate initial beamforming parameters for each communication region based on sounding messages received from a second network device. The first network device can determine coarse beamforming parameters for each communication region based on data packets received from the second network device using the initial beamforming parameters. The first network device can determine a difference parameter for the first communication region based, at least in part, on a first initial beamforming parameter associated with the first communication region and a first coarse beamforming parameter associated with the first communication region. The first network device can compare the difference parameter with a difference threshold to determine whether to estimate a first modified beamforming parameter for a first communication region.

Abstract: A first communication device can dynamically select a mode of communication (such as a MIMO mode or a SISO mode) to improve throughput. In selecting the communication mode, the first communication device may determine whether a powerline medium effectively supports multi-channel communication. Even when the first communication device and a second communication device both are capable of using a MIMO mode, the first communication device may select a SISO mode if it determines that one of the channels is ill-conditioned for communication. For example, the powerline medium may be affected by a missing conductor, protective circuit, or other attenuation that impairs the second channel differently than the first channel. If the disparity between the first channel and the second channel is greater than a threshold, the first communication device may switch to a SISO mode to improve performance.

Abstract: Aspects relate to outputting a training field signal and/or obtaining a training field signal over multiple radio frequency (RF) sub-bands. For example, a carrier bandwidth used by a first apparatus to transmit packets may include several RF sub-bands. The first apparatus may use two or more of these RF sub-bands to transmit a training field signal. In some examples, the first apparatus may repeat the same training field signal over multiple RF sub-bands. In some examples, the second apparatus may combine the training field signal sent over the multiple RF sub-bands.

Abstract: This disclosure provides several mechanisms for adapting transmit power spectral density (PSD). A communications device may adapt the power spectrum utilized at the transmitter based, at least in part, on the channel conditions or PSD constraints associated with the communications medium between the transmitter and a receiver device. Additionally, the transmit PSD may be adapted based, at least in part, on a total power capability associated with a transmitter. Power is allocated to improve throughput and utilization of the communications channel. A transmission profile may be selected based, at least in part, on the notch depth. The transmission profile may be associated with symbol timing parameters. The communications device may maintain a plurality of selectable pulse shapes that are optimized for different notch depths.

Abstract: Methods, systems, and devices are described for minimizing mutual interference between networks that implement different protocols. In one embodiment, a first network device of a first network may exchange coexistence information with a second network device of a second network to determine whether to share resources or reduce transmit power based, at least in part, on the interference detected at the first network device from a transmission of the second network device. In one embodiment, both the first and the second network devices may independently and iteratively reduce their respective transmit power to minimize interference between the interfering networks. The first network device may reduce its transmit power based on an interference of the second network device and vice versa. In another embodiment, the network device with a lower priority may minimize its transmit power to reduce interference with the network device with a higher priority.
