摘要： A method of detecting a desired signal within a composite signal provides for suppression of interfering signal(s). The method, implemented in a wireless communication apparatus, for example, includes receiving the composite signal and obtaining sample values therefrom. At least some of the sample values include desired and interfering signal components. The method further includes generating an interfering signal channel estimate by: forming sample pairs for some or all of the sample values; identifying sample pairs of interest as those sample pairs in which the interfering signal component is the same; and calculating the interfering signal channel estimate as an average value determined from one or more of the sample pairs of interest. The method further includes detecting desired signal symbols from the composite signal in a joint detection process that functionally depends on the interfering signal channel estimate.

摘要： Mobile communication system equipment avoids interfering with another transmitter's operation. Sensing information indicating whether the other transmitter's signal has been detected is received from remote sensors, wherein each of the remote sensors is situated at a respective one of two or more sensor locations. The sensing information and information about the sensor locations is used to ascertain one or more exclusion boundaries needed to avoid interfering with the other transmitter's use of the spectral resource. Beamforming parameters are ascertained that will enable the main node to transmit within one or more predefined geographical areas except for any portion of a predefined area located on a far side of the one or more exclusion boundaries. Two or more adjusted signals are produced as a function of the beamforming parameters and one or more signals to be transmitted. The adjusted signals are transmitted from respective ones of two or more antennas.

摘要： User equipment comprising a receiver obtains information about a set of channels to be sensed in a sensing process, wherein each channel is associated with a respective one of a number of radio frequencies. The receiver obtains a radio frequency signal by simultaneously sensing two or more of the channels included in the set of channels. A total power level of the sensed two or more channels is measured, and a comparison result is generated by comparing the total power level of the sensed two or more channels with a predetermined power level. The user equipment is controlled based on the comparison result. For example, if the total power level is below a threshold, then the sensed channels can be considered to not be in use by external transmission equipment.

摘要： An SIR estimate of a communication signal in a wireless communication system receiver Is calculated based on soft bit values output by a nonlinear detector. The average amplitude of the detector output soft bits is estimated. The average power of the detector output soft bits is estimated, e.g., as a mean-square or variance. An SIR of the communication signal is estimated based on the soft bit amplitude and power estimates. In particular, the SIR is estimated as the ratio of the square of soft bit amplitude to the difference between the mean square soft bit power and the square of soft bit amplitude, or the ratio of the square of soft bit amplitude to the variance. In either case, the SIR estimate may be scaled to obtain the desired units. The communication signal may be a received signal, or a simulated signal generated using channel estimates obtained from, e.g., a pilot channel.

摘要： Methods and apparatus for changing the transmission/reception setup of a base station (BS) in a communication network to another transmission/reception setup (such as one using fewer transmit antennas and/or lower channel bandwidths) without affecting communication with user equipments involve "replacing" the existing BS with a "virtual" BS that has the other transmission/reception setup. Replacement can be performed by, for example, ramping down the power of the existing, or first, BS, which has a respective first cell or node identification (ID), and simultaneously ramping up the power of the virtual, or second, BS, which has a respective second cell or node ID.

摘要： A method is disclosed of scheduling up-link transmissions for a number of terminals of a wireless communication system into a number of groups, wherein each group comprises terminals intended for simultaneous up-link transmission during a respective period of time. A subset metric may be calculated for each of a number of subsets of terminals based on transmissions received from the terminals of the subset. The subset metric is indicative of a simultaneous transmission suitability measure for the terminals of the subset. The subsets may be processed in subset metric order, starting with the subset having a subset metric indicating a least suitability of simultaneous transmission. During the processing, each terminal of the subset that is not already scheduled in a group may be scheduled in a group that does not already comprise another terminal of the subset. Information indicative of the period of time during which a scheduled terminal is intended to transmit may be transmitted to each of the scheduled terminals. Corresponding computer program product, scheduler and arrangement are also disclosed.

摘要： In an arrangement for two-dimensional positioning of a platform (32) in a microscope system, the platform (32) may travel along a first direction, which is perpendicular to the optical axis (33) of the system, supported by two guiding elements (12, 22). An actuator (18) introduces a deflection at a point (20) near one end (14) of a guiding element (12). The deflection propagates along different directions through a plurality of parts (11, 14, 12, 38, 32) and results in that parts of the platform (32) are moved along the optical axis (33). Some of the parts (11, 12, 32) that propagate the deflection, each give, by using other parts (10, 16, 22) as fulcrums of levers, multiplicative contributions to a total gear ratio, meaning that the move of the platform (32) near the optical axis (33) is just a fraction of the deflection introduced by the actuator (18).
