摘要： A system for communicating protocol layer processing information is disclosed herein. A transmitter includes a protocol layer header generator that generators a header for a first protocol data unit. The header generator provides a first header comprising a first sequence number field that determines the order in which a receiving entity present the first data unit to higher protocol layer. The sequence number field varies in length. A receiver includes a protocol layer header parser that parses a header of a first protocol data unit. The header parser parses a first header comprising a first sequence number field that determines the order in which the first data unit is presented to a higher protocol layer. The sequence number field varies in length.

摘要： Network circuitry and a method of operating the same in establishing and deleting a service flow in a wireless network. A network station receives a request, from an initiating network station, to establish a service flow. The network station receiving the request issues a response to that request, following which it expects an acknowledgement from the initiator. Upon absence of such an acknowledgement, the receiving station transmits a message, to the initiator, to explicitly delete the service flow. This ensures that the initiator is not placed into an ambiguous state of transmitting payload traffic to a receiver that is ignoring or not receiving that traffic, in the case in which the initiator is also the transmitter of the payload traffic. This circuitry and method also ensures that the initiator is not in an ambiguous state, in the case in which it is the intended receiver of the payload traffic.

摘要： A method of performing wireless communications. The method receives at a receiving unit a sequence of data blocks from a transmitting unit. The method also identifies at the receiving unit a first invalid sequential data block in the sequence. The method also communicates from the receiving unit a wireless message to the transmitting unit for provoking the transmitting unit to re-transmit a portion of the sequence of data blocks. The wireless message comprises a first field and a second field. The first field is for identifying the first invalid sequential data block. The second field is for identifying a last data block, from the sequence of data blocks, to which the wireless message applies.

摘要： A method of powerline communications including a first node and at least a second node on a PLC channel in a PLC network. The first node sends a physical layer (PHY) data frame on the PLC channel including a preamble, PHY header, a MAC header and a MAC payload. The PHY header includes a destination address field having a destination address therein. The second node receives the data frame. The second node compares its network address to the destination address before decoding the MAC header and MAC payload, providing power savings by allowing the second node to not decode the MAC header or MAC payload if its network address does not match the destination address in the PHY header of the data frame.

摘要： A method of powerline communications in a powerline communications (PLC) network including a first node and at least a second node. The first node transmits a data frame to the second node over a PLC channel. The second node has a data buffer for storing received information. The second node runs a flow control algorithm which determines a current congestion condition or a projected congestion condition of the data buffer based on at least one congestion parameter. The current congestion condition and projected congestion condition include nearly congested and fully congested. When the current or projected congestion condition is either nearly congested or fully congested, the second node transmits a BUSY including frame over the PLC channel to at least the first node. The first node defers transmitting of any frames to the second node for a congestion clearing wait time.

摘要： Systems and methods for designing, using, and/or implementing non-beacon network communications using frequency subbands are described. In various implementations, these systems and methods may be applicable to Power Line Communications (PLC). For example, a method may include transmitting a beacon request message over a given one of a plurality of frequency subbands, receiving a plurality of beacons in response to having transmitted the beacon request message, each of the plurality of beacons received over a respective one of the plurality of frequency subbands, and calculating a downlink quality report based, at least in part, upon the received beacons. The method may also include transmitting the downlink quality report over each of the plurality of frequency subbands and receiving a subband allocation command in response to having transmitted the downlink quality report, the subband allocation command indicating a downlink subband assignment and an uplink subband assignment.

摘要： A method of communications for a coexisting wireless network including a wireless combination (combo) device communicating via a first wireless network and second wireless network, and a first wireless device on the first network. During an activity interval for the second network (i) a transmit (Tx) time interval is longer in duration than a Tx packet duration and/or (ii) a receive (Rx) time interval is longer in duration than a Rx packet duration to provide remaining time. A frame aggregated packet is used on the first network that includes a plurality of data packets and a dummy packet or spoofing so that the frame aggregated packet is extended in time or indicates an extension sufficient to overlap the Tx time interval or Rx time interval. The combo device transmits or receives an acknowledgement (ACK) on the first network during the activity interval for the second wireless network.
