Abstract: A space time calibration method determines location and timing for nodes in a network using a model of the state of clocks in the network nodes and observations of clock count stamps over an observation interval. At least one of the nodes in the network is moving, and the nodes have free running clocks, with corresponding clock error parameters. The method obtains observations of clock stamps for transmissions between nodes occurring over a time interval. It applies the observations to a model of network state, and generates from the model an update of network state. This update is a function of the observations and an estimate of the network state. The network state provides estimates of location parameters and clock parameters of the nodes in the network.

Abstract: Mobile broadband traffic has been exploding in wireless networks resulting in an increase of interferences and reduced operator control. Networks are also becoming more heterogeneous putting additional demand in interference management. Scheduler schedules uplink transmissions from UEs based on a load prediction algorithm that typically assumes worst case. However, UEs do not always use full power granted, and thus, much of granted radio resources are wasted. To address these and other issues, technique(s) to accurately predict/estimate other cell interferences and thermal noise separately and to accurately predict/estimate load utilization probability and variance is(are) described. Inventive estimation technique(s) can be used to schedule UEs to more fully utilize available radio resources. Extended Kalman filtering can be adapted for use in estimation providing low order computational complexity.
