    摘要： A wireless communication device or system generates transmit power control feedback for a received power control channel by determining a command error rate (CER), or by identifying a target signal quality for the power control channel according to a defined signal-quality-to-CER mapping function. Generally, the power control channel does not include error-coded data to use for CER estimation. However, in one embodiment, the channel does include known reference bits that are evaluated for CER estimation, with the estimated CER used to set the signal quality target for inner loop power control. In other embodiments, a computed reception error probability is used to identify a CER estimate according to a defined probability-to-CER mapping function. By way of non-limiting example, these embodiments may be used to provide power control feedback for power control commands transmitted on a Fractional Dedicated Physical Channel in WCDMA systems.

    摘要： The velocity vector of a moving object is precisely determined by using radar measurements of the angle to and the radial speed of a moving object. This can be done in a radar system comprising one or more units. The technique also makes it possible to precisely determine the range to a moving object from a single moving radar unit.

    摘要： A method and a device for presenting digits, letters and other characters uses a number of signals for representing each character. Said signals are combined with signals from manually operable touch point electrodes. When predetermined electrodes are operated simultaneously with reception of a predetermind character signal or character signal combination, the combining means activates an acoustic, visual or tactile output signal so that a character representing signal code can be recognized. A code conversion between the input signals and the output signals can be provided so that the output character is presented in a code with fewer elements than the input character.

    摘要： Methods and apparatus are disclosed for detecting a control channel message transmitted on one of a plurality of shared control channels and targeted to a wireless receiver. In an exemplary method, messages transmitted over a plurality of shared control channels are decoded, and at least one likelihood metric is determined for each of the decoded messages. A best candidate is selected from the decoded messages, based on the likelihood metrics, and the at least one likelihood metric for the best candidate is compared to corresponding likelihood metrics for the messages other than the best candidate to determine whether the best candidate is a valid message. Wireless communication receivers configured correspondingly are also disclosed.

    摘要： A method, a device and a computer program product for the diagnosis of an oxidation catalyst for the oxidation of NO into NO2 in a motor vehicle is provided. An exhaust gas aftertreatment system includes at least the aforementioned oxidation catalyst and a particulate filter and/or an NOx-reducing catalyst arranged downstream of the oxidation catalyst, and a predetermined quantity of a reducing agent is supplied to the exhaust system upstream of the oxidation catalyst, and the NOx content or NO2 content is measured downstream of the oxidation catalyst. The method includes measuring a first value for the NOx/NO2 content at a point in time before the reduction agent is supplied to the exhaust gas system, measuring a second value for the NOx/NO2 content at a point in time during the period when the reduction agent is supplied to the exhaust gas system, and comparing the aforementioned values, in conjunction with which an indication of the impaired function of the oxidation catalyst is obtained when the difference between the aforementioned measured values is less than a predetermined first value.

    摘要： A method of channelization code selection for up-link transmission of a wireless communication system is disclosed. The method comprises determining, based on a first power limitation indication value associated with a first terminal of the wireless communication system, if the first terminal is power limited; dynamically selecting at least one first channelization code associated with a first signal variation value for allocation to the first terminal so that, if the first terminal is power limited, the first signal variation value indicates a first minimal signal variation; and signaling an indication of the at least one first channelization code to the first terminal. Corresponding arrangements are also disclosed.
