Abstract: Systems and methods for dynamically selecting and adjusting energy detection thresholds (EDTs) in uncoordinated radio nodes deploying Listen Before Talk to improve throughput on shared spectrum are disclosed. The uncoordinated radio nodes dynamically adjust an EDT to avoid harmful collisions with neighboring radio nodes or otherwise improve throughput over shared spectrum. A radio node can detect a collision or radio frequency (RF) interference from a neighboring radio node. Once the collision or RF interference is detected, the EDT of the radio node is dynamically adjusted. In some cases, the collision or RF interference can be avoided by calculating a throughput of the radio node while operating on each of a plurality of EDTs and selecting the EDT predicted to result in a higher throughput. In other cases, the EDT may be dynamically adjusted based on an iterative approach which incorporates measurements of the neighboring radio node.

Abstract: Systems and methods for dynamically selecting energy detection thresholds (EDTs) in radio nodes deploying listen before talk within a coordinated network to improve throughput on shared spectrum are disclosed. The radio nodes are configured to coordinate to deploy mechanisms to avoid or reduce interference issues, including collisions, with use of shared spectrum (e.g., unlicensed spectrum). One such mechanism is Listen Before Talk (LBT), and a radio node deploying LBT sets an EDT at which the radio node hears traffic from neighboring radio nodes on the shared spectrum. In an exemplary aspect, the EDT of radio nodes in the coordinated network of radio nodes can be dynamically selected and/or adjusted to improve throughput of the individual radio nodes and/or of the network of radio nodes as a whole.
