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.
