摘要： Disclosed embodiments pertain to a method on a UE may comprise determining a first absolute position of the UE at a first time based on GNSS measurements from a set of satellites. At a second time subsequent to the first time, the UE may determine a first estimate of displacement of the UE relative to the first absolute position using non-GNSS measurements. Further, at the second time, the UE may also determine a second estimate of displacement relative to the first absolute position and/or a second absolute position of the UE based, in part, on: the GNSS carrier phase measurements at the first time from the set of satellites, and GNSS carrier phase measurements at the second time from a subset comprising two or more satellites of the set of satellites, and the first estimate of displacement of the UE.

摘要： Disclosed are systems, methods and devices for application of determining position information for mobile devices. In specific implementations, measurement of a signal travel time and a signal's strength may be combined to characterize a transmission power of the signal's transmitter. The characterized transmission power may be applied to affect expected signal strength signature values for use of the signal's transmitter may be updated in order to enhance a location based service where location may be effected by accuracy of a transmitter's power.

摘要： Disclosed are implementations that include a method, performed by a network control device, including sending a first instruction to a first device to send a first measurement signal, and sending a second instruction to a second device to receive the first measurement signal. Following receipt of a first acknowledgement signal from the target mobile device, the first and second devices change their roles so the second device sends, and the first device receives, a second measurement signal, and the first and second devices receive a second acknowledgement signal from the target device. Position of the target device is determined based on timing measurements associated with the first and second measurement signals, the first and second acknowledgement signals, and on known positions of the first and second devices. Another network device is selected to perform additional measurements upon a determination that a desired accuracy of the position determined was not achieved.

摘要： Systems, apparatus and methods for determining a set of ranges from selected subcarriers of an OFDM signal sent between a receiver (e.g., first transceiver or a local receiver of a local unit at a first location) and a transmitter (e.g., second transceiver or remote transmitter of a remote unit at a second location) are presented. The set of ranges is ambiguous as to the correct range. Each range in this set of ambiguous ranges represents a possible range between the transmitter and the receiver. Range ambiguities may be resolved by using additional subcarriers from the OFDM signal and/or using a last know position of a receiver and/or finding ranges to two, three or more transmitters. The range may be used with other ranges to find a location estimate of the receiver.

摘要： Systems, apparatus and methods for determining a cyclic shift delay (CSD) mode from a plurality of CSD modes is disclosed. A received OFDM signal is converted to a channel impulse response (CIR) signal in the time domain and/or a channel frequency response (CFR) signal in the frequency domain. Matched filters and a comparator are used to determine a most likely current CSD mode. Alternatively, a classifier is used with a number of inputs including outputs from two or more matched filters and one or more outputs from a feature extractor. The feature extractor extracts features in the time domain from the CIR signal and/or in the frequency domain from the CFR signal useful in distinguishing various CSD modes.

摘要： Methods, systems, computer-readable media, and apparatuses for determining locations of access points (AP) are presented. Techniques are described for determining relative and absolute locations of APs. In one embodiment, a device may send and receive messages to one or more APs for from various locations for determining the distance between the device and the AP. The device may additionally keep track of its own displacement for the purposes of determining the location of the one or more APs. In one embodiment, the device also determines the turnaround calibration factor (TCF) for the AP that compensates for the processing time at the AP may also be used for increasing the accuracy of the determination of the location of the AP.
