Abstract: A first powerline communication device, associated with a first powerline communication network, determines a plurality of time intervals in a beacon period of the first powerline communication network based, at least in part, on variations in levels of interference from a second powerline communication network which shares a powerline communication medium with the first powerline communication network. The first powerline communication device determines at least one channel adaptation parameter for each of the plurality of time intervals in the beacon period to compensate for effects of the variations in the levels of interference from the second powerline communication network. The first powerline communication device applies the at least one channel adaptation parameter corresponding to one or more of the plurality of time intervals in the beacon period when transmitting data via the powerline communication medium.

Abstract: A feature-capable device that supports channel reuse and is part of a local network can determine whether to reuse or share a communication channel with a neighbor network when the local network and/or the neighbor network include at least one legacy device that does not support adaptive channel reuse. The feature-capable device can determine channel performance measurements associated with each legacy device in the local network and/or in the neighbor network. The feature-capable device can compare the channel performance measurements against corresponding performance thresholds. The local network and the neighbor network can reuse the channel if the channel performance measurements associated with each of the legacy devices meet the corresponding performance thresholds. The local network and the neighbor network can share the channel if the channel performance measurements of at least one of the legacy devices does not meet the corresponding performance thresholds.

Abstract: A service provider device of a local communication network communicates a first frame with an electric vehicle via a first communication medium to associate with the electric vehicle, establish a communication link with the electric vehicle, and to add the electric vehicle to the local communication network. After an association process between the electric vehicle and the service provider device is successfully completed, the electric vehicle and/or the service provider device can execute operations that extend the utility of their respective communication devices by switching to a new communication medium. By switching to the new communication medium, the electric vehicle and/or the service provider device can connect to a remote communication network. The service provider device communicates a second frame with at least a network device of the remote communication network via the new communication medium.

Abstract: 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.

Abstract: 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.

Abstract: A method comprises receiving a first message over a first portion of a frequency bandwidth. The first message includes an identifier of a transmitting first wireless device and an intended recipient second wireless device. The method comprises determining whether a second portion of the frequency bandwidth is idle for a duration of time including at least one of a PIFS time and a time required for a backoff timer to expire. The method comprises transmitting a second message over the second portion of the frequency bandwidth by a third wireless device, the second message having a limited transmission time that is not to extend beyond a transmission time of the first message, thereby allowing an availability of the first and second portions for use after an end of the transmission time of the first message. The third wireless device is not an intended recipient of the first message.

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.
