摘要： The invention features a method of estimating an expected error of a position estimate for use in a WLAN positioning system that estimates the position of a WLAN-enabled device. The WLAN-enabled device receives signals transmitted by a WLAN access point in range of the WLAN-enabled device. The method estimates the position of the WLAN-enabled device based on the received signals from the WLAN access point in range of the WLAN enabled device. The method also estimates an expected error of the position estimate based on characteristics of the WLAN access point in range of the WLAN enabled device, wherein the expected error predicts a relative accuracy of the position estimate.

摘要： The subject system aggregates, or stitches, multiple component channel estimates to generate an aggregated wideband channel estimate that can be used to determine more accurate time of arrival estimations than those determinable from the individual component channel estimates. The subject system also provides for multipath detection on a single channel or an aggregated channel that may be used to facilitate an accurate time of arrival estimation. For example, information derived from the multipath detection may be used to supplement and/or enhance a time of arrival estimation algorithm. The subject system also provides a sounding protocol that allows devices to perform one or more signal exchanges to facilitate generating the aggregated wideband channel estimate and/or to facilitate performing the multipath detection. The protocol allows the devices to perform signal exchanges over one or more channels within a coherence time, and also provides for security mechanisms as well as failure recovery.

摘要： Mobility parameters, such as those used in handoff decisions, are based on the speed of User Equipment UE. These parameters may include time to trigger (TTT), time to satisfy (TTS), measurement time, forgetting factor, β , measurement period ( T m ), handover prohibit timer, MeasurementReporting margin , HO margin , hysteresis, and the like. The mobility parameters are adapted by the User Equipment based on a speed estimate. The speed estimate is determined for the UE (10) at one or both of a base station and the UE, it is thereby
dynamically determined whether to determine the UE speed estimate at the base station or the UE in response to UE (10) transmission and reception activity modes.

摘要： A method and an apparatus for detecting motion activity of an object are suggested. The apparatus comprises: an RSSI detecting unit for obtaining the RSSI values of wireless signals; a first calculating unit for calculating a first indication relating to the status of movement/stillness of an object as a function of the Standard Deviation (STDEV) value of the RSSI values of the wireless signals over a first threshold; a second calculating unit for calculating a second indication relating to the speed of movement of the object as a function of the number of times that the RSSI values cross a second threshold from down to up during a time period; and a combining unit for outputting a third indication of the motion activity of the object by combining the first and the second indications.

摘要： The present invention relates to a method of determining a distance or location of a remote device or reflector, the method comprising: receiving a signal from a remote signal transmitter associated with or contained in or attached to the remote device; estimating a first propagation delay associated with the received signal, wherein the first propagation delay represents a first candidate for a correct propagation delay; deriving a relationship between the first candidate and one or more other candidates for a correct propagation delay from the received signal; determining a plurality of other candidates for a correct propagation delay based on said relationship; generating a likelihood histogram based on said candidates for a correct propagation delay; selecting a propagation delay from said candidates based on the likelihood histogram; and determining a distance or location of the remote device or reflector using the selected propagation delay.
