摘要:
A method performed by a wireless communications device for measurement reporting. The measurement reporting comprises reporting measurements associated with a first wireless communications network to a network node operating in a second wireless communications network. The first wireless communications network operates according to a first RAT, and the second wireless communications network operates according to a second RAT. The wireless communications device obtains (401), from the network node, an identifier of one or more radio access network nodes operating in the first wireless communications network. The obtained identifier restricts a mobility of the wireless communications device in the first wireless communications network to the one or more radio access network nodes identified by the identifier. The wireless communications device excludes (402) from measurement reporting to the network node at least one of the identified radio access network nodes.

The present disclosure provides a method (100) in a wireless device for initiating a handover from a source base station to a target base station. The method includes the steps of: calculating (S110) a power offset indicative of a difference between a receiving power from the target base station and a receiving power from the source base station; obtaining (S120) a Time Division Duplex (TDD) configuration difference between a TDD configuration of the target base station and a TDD configuration of the source base station; calculating (S130) a TDD offset based on the TDD configuration difference and an uplink-downlink traffic model of the wireless device; and initiating (S140) the handover when a combination of the power offset and the TDD offset exceeds a threshold. The present disclosure also provides a wireless device (600), a method (700) in a base station and a base station (800).

A voltage modulator (400) comprises a multi-level switched capacitor modulator (44) connected in parallel with a switched voltage regulator (42). An output of the multi-level switched capacitor modulator and an output of the switched voltage regulator are combined, or both connected to an output node, to generate an output voltage. The voltage modulator has an input node to receive at least one input signal and further comprises a control unit (46) arranged to control the switched voltage regulator and the multi-level switched capacitor modulator such that the output voltage follows the input signal.

An antenna arrangement comprising a SIW with at least one radiating arrangement. The SIW comprises a dielectric material, a first and second metal layer and a first and second electric wall element running essentially parallel and electrically connecting the metal layers. For each radiating arrangement, the antenna arrangement comprises at least one coupling aperture in the first metal layer, and for each coupling aperture there is a third wall element running between the first and second electric wall elements, across a SIW longitudinal extension (es). For each radiating arrangement, the antenna arrangement further comprises an at least partly electrically conducting antenna component which comprises at least four radiating elements and is surface-mounted on the first metal layer, enclosing at least one coupling aperture. For each radiating arrangement, electromagnetic signals are arranged to be transmitted between said coupling aperture and said radiating elements.

The application relates to the procedures Routing Area Update RAU in UTRAN and Tracking Area Update TAU in LTE. Furthermore, it relates to PDP context procedure in UTRAN as well as PDN connection procedure in LTE. In the current RAU procedure, a SGSN, which fails to update the Routing Area, e.g. because it receives the DNS return error, sends a RAU Reject with the cause code CC#17 indicating a network failure back to the user equipment (114b). The cause code CC#17 in the RAU Reject causes the user equipment to send a new RAU Request. Thus, the user equipment is stuck in a loop of sending a RAU Request and receiving a RAU Reject. This problem is solved by the present application in that SGSN keeps track of the number of rejections when doing RAU. When the number of rejections is above a certain threshold, the SGSN will send a RAU Reject with cause code CC#10 to the user equipment (115b), whereby the cause code CC#10 indicates implicit detach of the user equipment. In other words, the cause code is changed from CC#17 to CC#10 and in order to avoid further looping. The same principle is applied to TAU in LTE as well as to PDP procedures in UTRAN and LTE.
