摘要:
The present invention relates to a method and arrangement in a cellular communication system, in particular to methods and arrangements in a user equipment and a network node for reporting cell measurement results. The present invention provides improved methods and arrangements for reporting cell measurements without significantly increasing the complexity in the cell measurement procedure. The user equipment reports the number of transmit antenna ports used for performing cell measurements on each of the neighbouring cell in its measurement report to the network node. The network node receives the number of transmit antenna ports which enables the network to be aware of the actual number of antenna ports that are used for cell measurements.

The invention relates to a diecasting die (7) and a diecasting method for sprueless diecasting, in particular in a diecasting hot-runner system (1), wherein the diecasting die (7) is provided in a feeding region (8) for forming a plug of solidified molten material (22) that interrupts a flow of the molten material and can be completely remelted.The problem addressed by the present invention is therefore that of providing a diecasting die and a diecasting method according to the preamble of the invention that are suitable for different molten materials, in which a heating acts directly on the molten material with high power and largely without delay, a cooling is not required and the injection-molding method can be carried out at a high operating machine speed and under feeding conditions that can be monitored and reproduced well.The problem is solved by the feeding region (8) comprising direct resistance heating that produces a melting heat and is in direct thermal contact with the molten material (22). The problem is also solved by a diecasting method with the method steps of closing the casting mold, heating the diecasting die (7), melting the plug in the feeding region (8), stopping the heating, injecting the molten material (22) into the casting mold, maintaining the pressure of the molten material (22), solidifying the molten material (22) in the casting mold and in the feeding region (8) of the diecasting die (7), opening the casting mold (43, 44) and removing a cast part from the casting mold.

Network node (120) and method (300) in a network node (120), which is serving a user equipment (110), for instructing the user equipment (110) to send a measurement report in a wireless communication network (100) comprising the network node (120) and an underlay network node (130). The method (300) comprises estimating (302) an amount of data the user equipment (110) is expected to communicate. Further, the method (300) also comprises determining (303) the user equipment (110) to be a candidate for hand over to the underlay network node (130), based on the estimated (302) amount of data. Additionally, the method (300) comprises instructing (305) the user equipment (110) to send a measurement report.

A method in a first base station (105) for handling a data transferral in a cellular network (100) is provided. The first base station (105) serves a user equipment (125) via a first cell (115). When the first base station (105) obtains an indication that a second cell (120) provides a coverage for the user equipment (125), the first base station (105) sends a message to a second base station (110) serving the second cell (120). The message commands the second base station (110) to prepare for receiving the uplink data from the user equipment (125) via the second cell (120). The first base station (105) also sends a request to the user equipment (125). The request commands the user equipment (125) to prepare for sending the uplink data both via the first cell (115) and via the second cell (120) in respective separate intra frequency transmissions.

The invention relates to a method for radio-link monitoring in a user equipment (4) of a communication network (1). The user equipment (4) receives and/or sends on a first carrier using a primary radio access technology system (2) and on a second carrier using a secondary radio access technology system (3). The method comprises: receiving (100), from a network node (5), information about the primary radio access technology system (2) and the secondary radio access technology system (3), and determining (110), in dependence on information related to the primary radio access technology system (2) and the secondary radio access technology system (3), whether to monitor radio link criteria on: the first carrier on the primary radio access technology system (2), or both the first carrier on the radio access technology system (2) and the second carrier on the secondary radio access technology system (3). The invention also relates to a user equipment implementing the method.
摘要:
A method of controlling an unsynchronized cellular wireless telecommunication system includes, for at least one user equipment served by a first cell, receiving signal strength measurements and, based on the signal strength measurements, determining whether the user equipment should be scheduled for a low interference time period during which neighboring cells are configured to minimize interference in the first cell. The method additionally includes receiving neighboring cell time difference measurements from at least one mobile device within the first cell and, based on said measurements, determining a timing of transmissions from at least one neighboring cell relative to a timing of transmissions from the first cell. Additionally, the method includes defining the low interference time period based on the determined timing of transmissions from the at least one neighboring cell.

摘要:
In one aspect, the present invention in one or more embodiments improves mobility management—e.g., handover processing enhancement—by providing/utilizing additional information in combination with CoMP operation, for enhancing the handover procedure. For example, the additional information is used to improve judging the most suitable target cell (14). The additional information can be, for example, angle of arrival or time advance of the UE (20) in handover, RTT, power headroom or signal strength. In at least one embodiment, the information used for handover processing at source and/or target base stations (12-1, 12-2) is enhanced or otherwise made richer by the use of “geometric information” for mobile terminals (20). In one such embodiment, the geometric information used for handover processing associated with a given terminal (20) indicates something about the mobile terminal's position (relative or absolute).
