Network access selection between access networks
WI-FI/3GPP access selection techniques are used to control selection by a user terminal between cellular network cells and WI-FI cells. Cellular network cells providing overlapping coverage with WI-FI cells are correlated with the WI-FI cells. A received signal strength threshold is determined for each WI-FI cell based on an average throughput of the cellular network cells correlated with the WI-FI cell.

Increasing the threshold shrinks the effective coverage area of the WI-FI cell to allow user terminal only of strong RSSI to make connection to the Cell, and steers user terminal of weak RSSI away from the WI-FI cell. In contrary, decreasing the threshold expands the effective coverage area of the WI-FI cell and effectively allows more user terminal making connection to the WI-FI cell. |

Providing enhanced CSI coverage by reporting the same measure in multiple sub-frames
The application relates to channel state feedback reporting in wireless communication networks and in particular to modifications of the procedure for reporting CSI as specified by section 7.2 of 3GPP TS 36.213 V10.3.0. and the corresponding RRC protocol as specified by 3GPP TS 36.331 V10.2.0. The current cycle for CSI measurement and reporting is such that the UE performs separate CSI measurements for each report. However, the coverage area of CSI measurement reporting is lower than other uplink reporting such as e.g. ACK/NACK on PUCCH which supports subframe repetition, leading to an imbalance. Therefore, it is rather clear that it is highly beneficial to support coverage extension for CSI reports. The issue then arises as to how to realize the CSI coverage enhancement on top of existing/evolving CSI reporting framework. The application proposes to realize said CSI coverage enhancement by reporting (450) the same CSI report multiple times from the UE (110) to an eNB (220). |

Certificate management with consequence indication
A certificate management operation request is managed on a device, access to which is governed by an authentication certificate. Upon receiving a request to perform a certificate management operation on a certificate, a consequence of performing the certificate management operation is determined and the consequence is indicated via a user interface of the device.

Automatic 2D-to-stereoscopic video conversion
In general, a “Stereoscopic Video Converter” (SVC) provides various techniques for automatically converting arbitrary 2D video sequences into perceptually plausible stereoscopic or “3D” versions while optionally generating dense depth maps for every frame of the video sequence. In particular, the automated 2D-to-3D conversion process first automatically estimates scene depth for each frame of an input video sequence via a label transfer process that matches features extracted from those frames with features from a database of images and videos having known ground truth depths. The estimated depth distributions for all image frames of the input video sequence are then used by the SVC for automatically generating a “right view” of a corresponding stereoscopic image for each frame (assuming that each original input frame represents the “left view” of the stereoscopic image). |

Rotary joint including first and second annular parts defining annular waveguides configured to rotate about an axis of rotation
A rotary joint includes a contactless electrical connection that has an annular shape, not extending into a central region surrounded and defined by the annular contactless electrical connection. The annular shape of the electrical connection portions allows other uses for the central region, such as for passing an optical signal through the rotary joint. Feeds are coupled to annular waveguide structures in both halves of the rotary joint, for input and output of signals. The feeds may provide connections to the annular waveguide structures at regularly-spaced circumferential intervals around the waveguide structures, such as at about every half-wavelength of the incoming (and outgoing) signals. The annular waveguide structures propagate signals in an axial direction, parallel to the axis of rotation of the rotary joint. The signals propagate contactlessly (non-electrically-conductively) across a gap in the axial direction between the two annular waveguides. |
