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： Channel reuse permits more than one station to communicate concurrently via a communication medium. A first station may transmit a first transmission to a second station. A third station may detect the first transmission and determine a channel a channel reuse time period for a second transmission transmitted from the third station to a fourth station via the communication medium at least partially concurrently with the first transmission. The channel reuse time period may be based at least in part on estimated time to a next priority resolution slot (PRS) of the communication medium as determined from information in a start of frame (SOF) delimiter of the first transmission. The channel reuse time period may take into account a media access control (MAC) protocol data unit (MPDU) burst, and/or time periods associated with acknowledgement messages.

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 client network device may associate with a service provider to receive a service. For example, a client network device may transmit a number of broadcast messages to one or more service providers. The number of broadcast messages may be determined based, at least in part, on a first communication parameter received from at least one of the service providers. The client network device may receive first attenuation information from a first service provider after transmitting the number of broadcast messages. The client network device may associate with the first service provider based, at least in part, on the first attenuation information. In one example, a vehicle can associate with a charging station in a charging facility to securely communicate with and receive electric power from the charging station.

摘要： An adaptive filter bank can be implemented on a PLC device to dynamically adapt to variations in notching requirements and the performance of the PLC medium. The PLC device can apply filter coefficients to one or more filter elements of the adaptive filter bank to generate one or more notched subcarriers in the PLC band. A performance measurement of one or more subcarriers in the PLC band can be determined and evaluated against corresponding performance measurement thresholds. For a given notched subcarrier, if the performance measurement of the corresponding subcarriers is not in accordance with the performance measurement threshold, updated filter coefficients for the filter element configured to generate the notched subcarrier can be determined based, at least in part, on the performance measurement of the one or more subcarriers. The filter coefficients of the filter element can then be updated using the updated filter coefficients.
