摘要： A method of operating a terminal node (310) configured to communicate with one or more network nodes using a re-configurable relaying device (330), RRD, is provided. The RRD is re-configurable to provide spatial filters, each one of the spatial filters being associated with a respective spatial direction into which incident signals are selectively transmitted by the RRD. The method comprises receiving (6002) a plurality of positioning reference signals, PRSs, transmitted by the one or more network nodes, and, upon a first PRS (363) and a second PRS (362) of the plurality of PRSs being received from a same network node (320) of the one or more network nodes, the first PRS (363) being received along a path which is relayed at the RRD (330): transmitting (6006) a measurement report message comprising positioning information for the terminal node (310) based on at least the first PRS (363) and second PRS (362).

摘要： In a general aspect, a set of observed frequency-domain channel responses is filtered to remove noise or distortions that are not related to changes in the physical environment. In some aspects, for each frequency-domain channel response, a time-domain channel response is generated based on the frequency-domain channel response; and a filtered time-domain channel response is generated based on a constraint applied to the time-domain channel response. Additionally, a reconstructed frequency-domain channel response is generated based on the filtered time-domain channel response. An error signal is also generated, and a determination is made as to whether the error signal satisfies a criterion. The error signal can be indicative of a difference between the frequency-domain channel response and the reconstructed frequency-domain channel response. In response to each of the error signals satisfying the criterion, motion of an object in a space is detected based on the set of frequency-domain channel responses.

摘要： A method for mapping a surface using signals transmitted from a single transmitter comprises: receiving signals transmitted from the single transmitter, where each signal has a different propagation path; determining a motion of an antenna of the receiver; generating phasor sequences, where each phasor sequence represents a hypothesis based on antenna motion and a direction of arrival estimate for each received signal; compensating the received signals, local signals, or correlation results from correlating the received signals with the local signals using the phasor sequences based on the hypotheses to generate compensated correlation results; determining a preferred hypothesis in the hypotheses for each received signal that optimizes each correlation result; identifying a direction of arrival for each received signal using the determined hypothesis; determining a point of reflection from the direction of arrival of each received signal; and combining the points of reflection into one or more reflective surfaces.

摘要： Systems, methods, apparatuses, and computer program products for positioning measurements are provided. One method may include receiving, from a user equipment, a number of supported receive and transmit panels that can be simultaneously activated and/or a panel switch time. The method may then include computing or otherwise determining a UE-based latency lag using the number of supported receiver and transmitter panels that can be simultaneously activated and the panel switch time.

摘要： Systems and methods for determining user equipment (UE) locations within a wireless network using reference signals of the wireless network are described. The disclosed systems and methods utilize a plurality of in-phase and quadrature (I/Q) samples generated from signals provided by receive channels associated with two or more antennas of the wireless system. Based on received reference signal parameters the reference signal within the signals from each receive channel among the receive channels is identified. Based on the identified reference signal from each receive channel, an angle of arrival between a baseline of the two or more antennas and incident energy from the UE to the two or more antennas is determined. That angle of arrival is then used to calculate the location of the UE. The angle of arrival may be a horizontal angle of arrival and/or a vertical angle of arrival.

摘要： Systems and methods for providing improved accuracy for beacon-based location systems. A location estimation system may include a multi-beacon system which includes two or more beacons positioned proximate each other. The beacons emit correlated beacon frames which are time and data correlated. A mobile device receives the beacon signals and processes them to estimate the distance between the mobile device and the multi-beacon system. The mobile device processes the signals based on a correlation function of the beacons signal strength trends, which indicates homogeneity and reliability of the acquired signals. When the correlation is high, the two or more RSSI signals are stable and may be used for the distance estimation. When the correlation is low, at least one of the signals is irregular. The mobile device compensates for the irregular signal, signal, thus improving distance estimation accuracy.
