Abstract: After statically provisioned paths are created through an Ethernet network, trunks may be created to extend along those paths. The trunks extend between pairs of NNI interfaces on either end of the path, and Ethernet OAM may be run over the trunks to detect connectivity along the paths. Service instances and service groups may be provisioned over particular paths through the network. Each service instance/service group is associated with a trunk and the Ethernet OAM service on the trunk may be used to provide Ethernet connectivity OAM for the service instance/service group. Upon detection of a failure on the trunk, the service instances/service groups associated with the trunk may be caused to failover to an alternate path through the network. Thus, a single Ethernet OAM service instance may be used to provide connectivity verification so that connectivity detection does not need to be performed on each individual service instances/service group.

For example, a receiver can monitor received packets and determine whether any of data units in a given received packet were subjected to interference during transmission.

This indication enables the transmitter to distinguish between packet loss that occurred as a result of channel fade and packet loss that occurred as a result of interference. Consequently, the transmitter is able to invoke different actions depending on whether the packet loss is due to channel fade or interference.

Abstract: A wireless communications network may include multiple nodes, one of which is selected as a master node. The nodes may take turns broadcasting respective packets according to a predetermined broadcast schedule. During any given broadcast iteration, each node may broadcast a packet while the other remaining nodes receive the broadcast packet in parallel. In response to receiving the broadcast packet, each node may be configured to obtain desired estimated timing values. The estimated timing values may be transmitted back to the master node for use in computing time-of-flight information. Frequency-synchronization operations may be periodically performed to help reduce timing errors. The time-of-flight information, along with other location-based metrics, may be used in determining the relative positions of the multiple 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 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 grant 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.
