Abstract: A method performed by a node in a wireless communication network of estimating parameters used for determining a signal-to-interference measure at a communication device served by a base station, and a node performing the method. The method comprises acquiring an estimate of channel condition between the communication device and the serving base station, and between the communication device and at least one base station of a neighbouring cell, estimating the signal-to-interference measure using the estimate of the respective channel condition, and acquired output power and Physical Resource Block (PRB) utilization of each of the base stations, and receiving an indication of quality of a channel via which the communication device is served by the base station. The method further comprises determining whether a change in the estimate of the signal-to-interference measure is required based on the indication of channel quality, and updating the estimate of the channel condition.

Abstract: A system, apparatus, computer-readable medium, and computer-implemented method are provided for detecting anomalous behavior in a network. Historical parameters of the network are determined in order to determine normal activity levels. A plurality of paths in the network are enumerated as part of a graph representing the network, where each computing system in the network may be a node in the graph and the sequence of connections between two computing systems may be a directed edge in the graph. A statistical model is applied to the plurality of paths in the graph on a sliding window basis to detect anomalous behavior. Data collected by a Unified Host Collection Agent (“UHCA”) may also be used to detect anomalous behavior.

Abstract: Power Over Ethernet (POE)/universal power over Ethernet (UPoE) may be enabled at multigigabit port-channel connections. This may allow for additional speed support in auto-negotiation messages while employing multigigabit speeds. An integrated connector module (referred to herein as a “ICM”) compatible with UPoE with a modified local physical layer (PHY) circuit may be capable of supporting multi-gigabit data rates (such as between 1 G to 10 G, e.g., 2.5 G and 5 G) as to not limit the data rates to 1 G. The ICM may provide multi-gig data transmission through a first plurality of pins comprising a multi-gig data pin area. Furthermore, the ICM may provide UPoE power to support the multi-gig transmission through a second plurality of pins comprising a UPoE power pin area.

Abstract: A method and a network node (110, 111) for determining first channel state information in an upcoming time slot for use by a first radio network node (111) when determining a set of radio transmission parameters for a transmission between the first radio network node (111) and a second radio network node (121) are provided. The net work node (110, 111) receives (201) second channel state information for said upcoming time slot. Furthermore, the network node (110, 111) determines (207) third channel state information for said upcoming time slot. The second and third channel state information are at least partly non-overlapping with each other. Next, the network node (110, 111) determines (208) the first channel state information, for said upcoming time slot, based on the second channel state information and the third channel state information.

Abstract: Applicants have discovered that error detection techniques, such as Forward Error Correction techniques, may be used to predict the degradation below a certain threshold of an ability to accurately convey information on a communication channel, for example, to predict a failure of the communication channel. In response, transmission and/or reception of information on the channel may be adapted, for example, to prevent the degradation below the threshold, e.g., prevent channel failure. Predicting the degradation may be based, at least in part, on data transmission error information corresponding to one or more blocks of information received on the channel and may include determining an error rate pattern over time. Based on these determinations, the degradation below the threshold may be predicted and the transmission and/or reception adapted. Adapting may include initiating use of a different error encoding scheme and/or using an additional communication channel to convey information.
