Abstract: The present invention relates to a method for synchronising a node in a deterministic mesh network, in particular a network of sensors using a channel hopping (TSCH) transmission medium access mode. Each node measures the successive synchronisation offsets of its local clock in relation to those of neighbour nodes with which it enters into communication, the measurement being carried out by detecting a reception event of a packet transmitted by the neighbour node or an acknowledgement of a packet transmitted by said node to the neighbour node. The node estimates from these synchronisation offsets, a synchronisation offset for the timeslot and corrects its local clock by a fraction of the synchronisation offset thus estimated. Said fraction may be determined by means of multi-agent reinforcement learning (MARL), each agent being associated with a node of the network.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for reducing the overhead associated with reporting feedback, such as hybrid automatic repeat request (HARQ) feedback. A user equipment (UE) may receive a configuration message from a base station indicating that the UE is to request resources for transmitting negative acknowledgment (NACK) feedback for a downlink transmission.

Because the UE may be configured to request resources on which to transmit the NACK feedback, the UE may avoid transmitting HARQ feedback for every downlink transmission from the base station. Thus, the base station may avoid allocating resources for HARQ feedback from the UE for every downlink transmission, and the overhead of reporting HARQ feedback is reduced.

Abstract: Uplink messages in 5G and 6G are expected to arrive at the base station in alignment with the base station's resource grid, at the proper time and frequency. Disclosed are lean procedures and compact timing signals that can enable user devices to maintain synchronization with a base station's resource grid.

The receiver's amplitude resolution corresponds to the time resolution achievable. No special time-measurement signal processing is required. No synchronization messages or other legacy overhead are required.
