Abstract
Frequency synchronization methods provide synchronization among nodes of a decentralized communication network. At each of one or more nodes of a plurality of nodes that form a decentralized communication network, information is acquired that is indicative of a frequency associated with at least one other node of the plurality of nodes. For each of the one or more nodes, a frequency offset between a frequency of the node and a frequency of the at least one other node is determined, based in part on the acquired information.
Claims25
A method for frequency synchronization, the method comprising:
- at each of one or more nodes of a plurality of nodes that form a wireless decentralized communication network, acquiring information indicative of a frequency associated with at least one other node of the plurality of nodes, wherein for each of the one or more nodes the acquiring includes:
- receiving and decoding at least one signal transmission from a neighboring node, the at least one signal transmission associated with metadata that includes frequency compensation information between a local frequency of the node and a local frequency of the neighboring node, and
- setting a measurement time frame that follows a reference clock of a time source that provides timing synchronization for the wireless decentralized communication network;
- and
- determining, for each of the one or more nodes, a frequency offset between a frequency of the node and a frequency of the at least one other node based at least in part on the acquired information.

A wireless decentralized communication network comprising a plurality of nodes, wherein for each node of one or more nodes of the plurality of nodes the node is configured to:
- acquire information indicative of a frequency associated with at least one other node of the plurality of nodes by:
- receiving and decoding at least one signal transmission from a neighboring node, the at least one signal transmission associated with metadata that includes frequency compensation information between a local frequency of the node and a local frequency of the neighboring node, and
- setting a measurement time frame that follows a reference clock of a time source that provides timing synchronization for the wireless decentralized communication network, and
- determine a frequency offset between a frequency of the node and a frequency of the at least one other node based at least in part on the acquired information.

A device deployed at a node that is one of a plurality of nodes that form a wireless decentralized communication network, the device comprising:
- an acquisition module configured to acquire information indicative of a frequency associated with at least one other node of the plurality of nodes of the decentralized communication network, wherein the acquisition module includes:
- a transceiver configured to receive and decode at least one signal transmission from a neighboring node of the decentralized communication network, the at least one signal transmission associated with metadata that includes frequency compensation information between a local frequency of the node and a local frequency of the neighboring node, and
- a timing module configured to set a measurement time frame that follows a reference clock of a time source that provides timing synchronization for the wireless decentralized communication network;
- and
- a frequency offset module configured to determine a frequency offset between a frequency of the node and a frequency of the at least one other node based at least in part on the acquired information.
