Abstract: 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.

Abstract: Systems and methods for beacon selection in communication networks are described. In various implementations, these systems and methods may be applicable to Power Line Communications (PLC). For example, a method may include performing, using a terminal device deployed in a communications network, receiving a beacon transmitted by a switch device within the communications network and, in response to the terminal device having had a previous connection with the switch device, determining a connection time of the previous connection. The method may also include performing at least one of: adding the switch device to a blacklist in response to the connection time being smaller than a first threshold value, or selecting the switch device for subsequent communication in response to the connection time being greater than a second threshold value.

Abstract: 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.

Abstract: 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.

Abstract: Embodiments of the invention provide a method to efficiently enable Network MIMO for use in the downlink direction. An association is established between a primary NodeB in a first cell and a secondary NodeB in an adjacent second cell. A set of downlink transmission resources is reserved for use by both the primary NodeB and the secondary NodeB. A transport block is transmitted from the secondary NodeB simultaneously with the primary NodeB to a user equipment (UE) near the edge of the first cell in response to a schedule provided by the primary NodeB. A time instance of the reserved transmission resources is released by the secondary NodeB when no simultaneous transmission of a transport block is scheduled within a minimum time.
