Certain aspects of the present disclosure relate to assisting communications with low data payloads with relay nodes. An example method generally includes forming a first cluster with a first wireless node and one or more second wireless nodes, wherein each of the second wireless nodes has a low data rate demand relative to a system bandwidth. The method also includes determining to serve as a relay node for the first cluster, generating a first set of packets for uplink transmission to a base station, receiving a second set of packets from the one or more second wireless nodes, combining the first set of packets and the second set of packets into an uplink payload based on the determination, and transmitting, to the base station, the uplink payload based on the determination.

A signal forwarding device receives a dual-encoded first set of data that is encoded according to first and second sets of encoding parameters. The signal forwarding device decodes the dual-encoded first set of data, using decoding parameters that correspond to the second set of encoding parameters, to generate a single-encoded first set of data that is encoded according to the first set of encoding parameters. The signal forwarding device transmits the single-encoded first set of data to the destination device, which decodes the single-encoded first set of data using decoding parameters that correspond to the first set of encoding parameters. If the decoding is unsuccessful, the destination device requests retransmission. The signal forwarding device decodes a stored copy of the single encoded first set of data, using decoding parameters that correspond to the first set of encoding parameters, and retransmits the first set of data to the destination device.

An ultrawideband radio transceiver/repeater provides a low cost infrastructure solution that merges wireless and wired network devices while providing connection to the plant, flexible repeater capabilities, network security, traffic monitoring and provisioning, and traffic flow control for wired and wireless connectivity of devices or networks. The ultrawideband radio transceiver/repeater can be implemented in discrete, integrated, distributed or embedded forms.

A wireless communication system comprises a base station and one or more relay docks and transmits directional wave signals between components using high frequency waves, such as millimeter waves. A beam forming decision engine utilizes position information collected from one or more position or motion sensors of a user device to determine a direction in which to form a directional wave signal being transmitted between components of the wireless communication system.

Methods and devices for propagating transactions in a network of nodes, each node having one or more connections to other nodes. The method includes determining that one of the nodes is a bottleneck for propagation of transactions; receiving, over a first time period, a plurality of new transactions from one or more first nodes in the network of nodes; combining the plurality of new transactions using network coding and a local encoding vector to generate a message; and sending the message and a global encoding vector to one or more second nodes in the network of nodes instead of sending the plurality of new transactions to the one or more second nodes. The network may be a blockchain network.

A relaying method in a telecommunication system having a plurality of sources, a half-duplex relay and a recipient. The relay performs a receiving phase of: receiving codewords transmitted by the sources, including estimating for each source a message associated with the codewords transmitted by the source, error detection and decision of error-free decoded messages, which determine the set of sources decoded without error by the relay; a phase of coding and transmitting to the recipient a signal uniquely representative of the selection of messages, such that, after each reception of a block from different sources, the relay receives and decodes a return path from the destination indicating if no or at least one message is decoded without error, these messages determining the set of sources decoded without error. The relay switches from the receiving phase to the coding and transmission phase once a logic rule is valid.
