摘要： 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.

摘要： 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.

摘要： A non-liner device (NLD) between powerline communication (PLC) devices can introduce significant distortion into the channel being utilized by the PLC devices. This distortion can create errors and corrupt data transmitted by the PLC devices. When trying to mitigate the effects of the distortion introduced by NLDs, PLC devices conform their mitigating actions to effectively satisfy a limit(s) set by a regulation and/or a standard. A PLC device implemented in accordance with this disclosure can mitigate the distortion effects with deference to regulatory/standard limits without knowledge of what types of NLDs and how many NLDs are coupled to the power line. A PLC device can use different techniques to infer the presence of an NLD in a PLC network. A PLC device can infer the presence of the NLD using a passive technique or one or more active techniques.

摘要： A method includes determining a signal strength value for a first received signal received from a first station in a first network. The first received signal is received in the first network through a shared communication medium that is shared with a second network. The method includes receiving an indicator of a signal strength value determined for a second received signal from a second station in the second network. Based on the signal strength value for the first received signal and based on the indicator of the signal strength value determined for the second received signal, a detection threshold is selected such that, in response to a third received signal having a signal strength in excess of the detection threshold, the third received signal is processed according to a protocol of the first network and is not processed according to a protocol of the second network.

摘要： Described herein is datagram segmentation and acknowledgment in a network. A communication node in the network may determine a length of a datagram is greater than a maximum protocol data unit (PDU) length of a protocol of the network and create a segmented message comprising the datagram and a payload length field indicating the length of the datagram. The node may then segment the segmented message into segments and create a PDU comprising one or more of the segments and a segment number least significant bits (LSB) field comprising least significant bits of a segment number associated with the one or more segments. The PDUs may be acknowledged using selective acknowledgment (SACK) messages. The SACK message may comprise a SACK type indicator, a segment number most significant bits (SN_MSB) indicator, and a payload comprising one or more least significant bits (LSBs) of a segment of the segmented message.

摘要： A hybrid network may include a mix of different network technologies and devices. A multi-interface device, such as a hybrid device, may provide for bridging of frames between different networks. Some routing schemes may not be suitable for a hybrid network. In this disclosure are various concepts for a routing scheme suitable for a hybrid network. In accordance with a routing scheme, one or more routing trees may be determined based on a topology map for the hybrid network. The topology map may include nodes to represent different interfaces of at least one multi-interface device. A routing tree determined based, at least in part, on the topology map may be used to manage routing of frames in the hybrid network.
