Based on the signal, the user equipment can perform interference reduction or cancellation. | 12-17-2015 |
| 20160044650 | METHODS AND APPARATUS FOR INTERFERENCE MANAGEMENT - Systems and techniques for interference management. A set of CSI-RS subframe configurations is established, and a mapping specified associating each CSI-RS subframe configuration with a corresponding CSI-RS configuration subset indicator, such that the CSI-RS configuration subset indicator identifies allowed CSI-RS subframe configurations at a first base station. The specified mapping is stored at the base station, and the configuration subset indicator is signaled to neighboring base stations. In response to receiving one or more CSI-RS configuration subset indicators at a user device from a serving base station, a determination is made for each of plurality of subframes whether one or more CSI-RS subframe configurations represented by the one or more CSI-RS configuration subset indicators indicates a CSI-RS presence in the subframe. If the one or more subframe configurations indicates a CSI-RS presence, at least partially clean resource element (RE) cancellation interference is applied in the subframe. | 02-11-2016 |

| 20160032609 | CLAMPING MECHANISM, LOCKING ARRANGEMENT AND METHOD OF OPERATING RECONFIGURABLE MANIPULATOR - A clamp mechanism is disclosed, clamping on a tube made of elastic material, provided with a band clamped on a tube. Inside the tube, in the location where the band clamps, a stiff element is located having a diameter substantially corresponding to the inner diameter of the tube. The band encompasses the tube over the length of at least the half of its circumference and is connected to a tensioning and releasing apparatus. A locking system for a manipulator is also provided including tubes substantially parallel to each other. Each tube is formed of curling strip wound on a drum rigidly connected to a structure. The manipulator has at least one reconfigurable parameter. The system includes a mechanism that is mounted on each one of tubes. Further, a method of operating a reconfigurable manipulator is disclosed including curled strip tubes, wherein the manipulator is provided with a locking system, which is released for reconfiguration of the manipulator and clamped for normal operation. | 02-04-2016 |
| 20160047182 | DRILLING HEAD DRIVING DEVICE, SPRAGGING MECHANISM AND DRILLING METHOD - The object of the invention is a spragging mechanism for application in a tube. It is provided with a band and clamping means. The clamping means are arranged within the tube, outside of which the band is provided. The object of the invention is also a system for guiding bore head, provided with an spragging mechanism, head, means transferring the pressing force to the bore head, and also a curled tube fed from the drum into the wellbore. The curled tube ( | 02-18-2016 |
