摘要： A technique for handling data provided from a source node to a collecting node in a data network is described. As to a method aspect of the technique, the source node generates a sequence of values. The sequence is unrevealed in the data network by the source node in a time interval. An authentication of the sequence is triggered in the data network. The authentication associates the sequence with the source node. One or more signatures for one or more data sets to be sent in the time interval are computed using one or more values of the sequence. The one or more data sets in the time interval are sent from the source node to the collecting node. The source node further provides one or more of the signatures.

摘要： A user equipment (UE) is configured to operate in an E-UTRA network. The UE is configured to transmit, to the E-UTRA network, a capability indication message indicating that the UE is capable of receiving, from the E-UTRA network, a measurement configuration message comprised in a radio resource control (RRC) configuration message, wherein the measurement configuration message comprises an instruction that the wireless communication device should use a first or a second Reference Signal Received Quality (RSRQ) measurement method, wherein in the first method, a receive signal strength indicator (RSSI) is measured only from orthogonal frequency-division multiplexing (OFDM) symbols containing reference symbols for antenna port 0; and in the second method, the RSSI is measured over all OFDM symbols in a subframe. The UE receives the RRC configuration message comprising said measurement configuration message; performs the RSRQ measurement method specified in the instruction; and sends, to the E-UTRA network, a measurement report message indicating a result of the RSRQ measurement.

摘要： A circuit for calibration measurements comprises a first and a second current source arranged to provide current outputs; a resistor connected between the first current source and a reference voltage; a capacitor connected between the second current source and the reference voltage; a discharge switch connected in parallel with the capacitor and arranged to selectively discharge the capacitor; a comparator circuit arranged to compare voltages across the resistor and the capacitor and output a signal when voltage across the capacitor reaches the voltage across the resistor; and a controller having a clock signal input and connected to the output of the comparator circuit. The controller is arranged to control the discharge switch to discharge the capacitor, change state of the switch to enable charging of the capacitor and count clock signal pulses until the comparator provides the signal when voltage across the capacitor reaches the voltage across the resistor, wherein the controller is arranged to determine a calibration measurement from counted number of clock signal pulses. A method, computer program and electronic device are also disclosed.

摘要： A mobile device that comprises a main receiver and a wake-up receiver is operated by periodically attempting to receive a first signal that is configured for receipt by the wake-up receiver. For each attempt, a detection result is generated that indicates whether the first signal was received with a signal quality that satisfies a predetermined minimum quality criterion. One or more of the detection results are used as a basis for deciding whether or not the wake-up receiver is within range of an access point. An operation of the mobile device is adjusted in response to a decision that the wake-up receiver is not within range of the access point.

摘要： A wireless communication device communicates with a GPRS wireless network where ciphering has gone out of sync between the wireless communication device and the wireless network. The wireless communication device triggers an authentication procedure that re-synchronizes the ciphering. Following the trigger, the wireless communication device and the wireless network continue the authentication procedure so that ciphering parameters can be negotiated again and data communication can resume.
