Abstract: Utilizing multiple network interfaces when sending data and acknowledgement packages comprises, in a low power and lossy network (LLN) or other network, a sender device comprises two or more network interfaces for communicating with one or more recipient devices. The sender device assesses the transmission capabilities of the network interfaces to determine data rates available for each interface. The sender device specifies which network interface will be used to transfer data and which network interface will be used to receive an acknowledgement from the recipient device. The sender device selects the network interface with the larger data capacity for transmitting a data packet and the network interface with the smaller data capacity for receiving an acknowledgement. The data transmission and the acknowledgement transmission may be transmitted simultaneously.

Abstract: In a multi-PHY, low power and lossy network comprising a plurality of nodes, a sender determines that a dwell time threshold limit for transmission of data will be exceeded by transmission of the data over a first network interface or that the recipient is unknown. The sender determines transmission parameters for the transmission of the data over the first network interface and transmits the transmission parameters to a receiver device over a second network interface that is different than the first network interface. The sender determines a channel on the first network interface for transmission of the data and transmits the determined channel with the transmission parameters to the receiver, or the receiver determines the channel on the first network interface for transmission of the data and transmits an indication of the determined channel to the sender in response to receiving the transmission parameters.

Abstract: In one embodiment, a device connected to a network receives at a network interface a first network size indicator for a first network and a second network size indicator for a second network. A difference between the first network size indicator and the second network size indicator is determined and a switching probability is calculated if the difference between the network size indicators is greater than a predetermined network size difference threshold. The device may then migrate from the first network to the second network based on the switching probability.

Abstract: In one embodiment, a rendezvous request message is generated (e.g., by a sender) that specifies a channel C and a rendezvous time T for which a distributed message is to be transmitted in a frequency-hopping computer network. The rendezvous request message is then transmitted on one or more channels used in the computer network based on reaching a plurality of intended recipients of the distributed message with the rendezvous request message prior to rendezvous time T. Accordingly, the distributed message is then transmitted on channel C at rendezvous time T. In another embodiment, a device receives a rendezvous request message, and in response to determining to honor the rendezvous request message, listens for the distributed message on channel C at rendezvous time T.

Abstract: In one embodiment, a device may select, based on an optimal tone map, a particular subcarrier for use when transmitting a data frame, the data frame to serve as a tone map request (TMREQ). The device may then populate one or more unused quality subcarriers of the TMREQ data frame other than the particular subcarrier with a well-known bit sequence, and transmits the TMREQ data frame to a receiving device to cause the receiving device to evaluate transmission quality of the one or more unused quality subcarriers based on the well-known bit sequence.

Abstract: There is provided a mechanism for controlling communications conducted via different frequency bands or communication spectrums. When a communication via a first communication path, for example an unlicensed or white space communication spectrum, is to be established, e.g. for offloading traffic from a second communication path, for example a licensed cellular communication spectrum, a preamble transmission command is generated and transmitted from a communication network control element, such as an eNB, via the second communication path to a communication element, such as a UE. By means of the preamble transmission command, the transmission of a preamble signal by the receiving communication element on the first communication path with predetermined communication resources is triggered.

Abstract: In one embodiment, a time at which a first device in a frequency-hopping communication network is expected to transmit a data message is determined. A first schedule is then generated based on the determined time, and the first schedule is overlaid on a frequency-hopping schedule for a second device in the network. The first schedule defines a first timeslot during which the second device listens for the data message, while the frequency-hopping schedule defines second timeslots during which the second device listens for data messages from other devices in the network. Notably, a duration of the first timeslot is greater than respective durations of the second timeslots.

Abstract: A method, apparatus and computer program product are provided facilitating flexible time sharing among systems. A method and apparatus may generate a secondary component carrier transmission plan including planned on and off durations. The planned on durations correspond to a time period for an apparatus and devices to communicate via an unlicensed band of the secondary component carrier. The planned off durations correspond to a time interval in which the devices may deactivate from the unlicensed band or remain disconnected from the unlicensed band. The method and apparatus may also enable provision of the plan to the devices via a licensed band of a primary component carrier and detecting a medium of the unlicensed band prior to the expiration of the time period to determine whether the medium is available in order to decide whether to turn on transmissions to the unlicensed band after one of the planned off durations.

Abstract: In one embodiment, an aggregating node receives feedback messages from one or more destination nodes in the network. The destination nodes are designated to receive data as packets from a source node using rateless coding. Further, the feedback messages indicate whether packets are needed at a corresponding destination node to complete the data. Then, the feedback messages are aggregated into a single aggregated message, and the aggregated message is transmitted toward the source node.

Abstract: In one embodiment, a device receives and stores a broadcast schedule, and may determine whether a neighbor unicast listening schedule is available for a neighboring device. If so, the device may transmit a data frame to the neighboring device pursuant to the neighbor unicast listening schedule. If a neighbor unicast listening schedule is not available, the device may transmit the data frame to the neighboring device pursuant to a broadcast schedule. Once the data frame is received by the neighboring device, pursuant to the neighbor unicast listening schedule or the broadcast schedule, an acknowledgement may be received from the neighboring device, which may include an updated neighbor unicast listening schedule for that neighboring device.

Such measures may exemplarily comprise classifying each one of served terminals into one of two transmission groups, assigning an uplink-downlink configuration of a frame structure for time division duplex communication for each one of the two transmission groups such that uplink subframes for one transmission group and downlink subframes of the other transmission group coincide with each other, and scheduling uplink and downlink transmissions for the served terminals on a single carrier according to the assigned uplink-downlink configurations for the two transmission groups.

Abstract: In a multiple interface, low power and lossy network comprising a plurality of nodes, a low transmission power and medium transmission power topology are defined for the network and a channel-hopping schedule is defined for the devices operating in each topology. A sender determines that data is capable of being transmitted via a link on the low transmission power topology. The sender determines the transmission parameters for the transmission of the data over the link on the low transmission power topology and determines a low transmission power channel for transmission of the data. The sender transmits the determined channel and the transmission parameters to the receiver. The sender transmits the data via the determined channel in the low transmission power topology.
