摘要： A powerline communication (PLC) device can be configured to execute functionality for zero cross sampling and detection. When the PLC device is directly coupled to a high-voltage PLC network, the PLC device can comprise printed safety capacitors in series with a high-voltage input AC powerline signal to safely couple the high-voltage AC powerline signal to the low-voltage processing circuit. The PLC device can also comprise an ADC to sample a scaled AC powerline signal and to obtain zero cross information. When the PLC device is part of an embedded PLC application, dynamic loading can affect the integrity of a low voltage zero cross signal that is used to extract zero cross information. After digitizing the zero cross signal, the PLC device can execute functionality to minimize/eliminate voltage drops caused by dynamic loading and obtain the zero cross information.

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 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 slotted message access protocol can be implemented for transmitting short packets. Each beacon period may be divided into multiple time slots. At least one time slot may be assigned to a network device per beacon period based, at least in part, on latency specifications of packets that the network device is configured to transmit. In one example, some of the unassigned time slots may be designated as contention-based time slots. Network devices may contend with each other to gain control of and transmit packets during a contention-based time slot based on the priority level of the packets to be transmitted. Network devices may also use an encryption key and an initialization vector for securely exchanging short packets. Furthermore, a repeater network device may be designated to retransmit a packet, received from an original transmitting network device, during a communication time slot assigned to the original transmitting network device.

摘要： Network devices can be configured to implement adaptive power control functionality in a communication network. A power control requestor of a local communication network can calculate a link margin between a neighbor network device of a neighbor communication network and a local network device associated with a least preferred performance measurement. The power control requestor can transmit a power control message including the link margin to request the neighbor network device to vary the transmit power of the neighbor network device. In response to receiving a power control message, a power control responder can use a link margin indicated in the power control message to evaluate the feasibility of reducing the transmit power of the power control responder. The power control responder can transmit a power control response indicating whether it will vary the transmit power.

摘要： Line cycle adaptation periods may have variable duration. A powerline cycle may be segmented into a plurality of line cycle adaptation periods having variable duration based upon signal-to-noise (SNR) characteristics measured at various times throughout the powerline cycle. The line cycle adaptation periods may include at least two periods with unequal durations. Each line cycle adaptation period may be associated with one or more tone maps defining physical layer transmission properties to be used by a second device for transmissions occurring during the line cycle adaptation period.

摘要： A method includes determining, at a first transmitter, whether to permit reuse of a first transmit opportunity (TXOP) associated with a message. The method further includes sending a portion of the message from the first transmitter to a first receiver. The portion of the message indicates whether reuse, by a reuse transmitter, of the first TXOP is permitted. When reuse of the first TXOP is permitted, the reuse transmitter is permitted to send a second message while the first transmitter sends a second portion of the message to the first receiver during the first TXOP.
