Abstract:
Methods, systems, computer-readable media, and apparatuses for determining a position of a mobile device connected to a network are presented. In various embodiments, the mobile device obtains a synchronization status of the network associated with one or more base stations. If the synchronization status indicates that the network is synchronous, the mobile device determines the position of the mobile device using previously collected crowdsourced time correction data for the synchronous network.
Abstract:
Systems, methods, apparatuses, and computer-readable media for adaptive wake-up scheduling under PRS muting are disclosed. For example, A mobile device can measure a plurality of reference signals for positioning having a muting pattern cycle comprising two or more time periods. The mobile device, during an evaluation phase, can receive during one or more evaluation time periods within the muting pattern cycle, reference signals detectable by the mobile device during the one or more evaluation time periods within the muting pattern cycle. The mobile device can determine a subset of the muting pattern cycle for measuring reference signals, where the subset of the muting pattern cycle comprises a number of time periods fewer than the two or more time periods of the muting pattern cycle. The mobile device then measures reference signals only during the determined subset of the muting pattern cycle.
Abstract:
Systems, methods, apparatuses, and computer-readable media for adaptive wake-up scheduling under PRS muting are disclosed. For example, a mobile device can receive a positioning reference signal measurement configuration for a muting pattern cycle having two or more time periods from a server. The mobile device then measures reference signals only during a subset of the two or more time periods of the muting pattern cycle based on the reference signal measurement configuration.
Abstract:
Example methods, apparatuses, and/or articles of manufacture are disclosed herein that may be utilized, in whole or in part, to facilitate and/or support one or more operations and/or techniques for targeted positioning reference signals (PRS) configuration searches, such as for use in or with mobile communication devices, for example.
Abstract:
A mobile station performs Observed Time Difference of Arrival (OTDOA) positioning by measuring a time of arrival (TOA) of downlink signals transmitted from a reference cell and one or more neighbor cells. Reference Signal Time Differences (RSTDs) are generated using TOA measurements from the reference cell and each neighbor cell. The mobile station reports to a location server location information, including the RSTD measurements and the times of measurement for the TOA measurements. The mobile station may further generate and report additional RSTD and/or TOA measurements and associated times of measurement for the reference cell and/or neighbor cells. A location server may use the RSTD measurements, the times of measurement and any TOA measurements to determine a position of the mobile station taking into account user motion and base station clock drift and/or may adjust the uncertainty of the resulting position.
Abstract:
A mobile device position determination method includes: determining a plurality of bandwidths of a pilot signal corresponding to different times at which the pilot signal is received by a mobile device from a base station, the plurality of bandwidths of the pilot signal including a first bandwidth corresponding to a first time at which the pilot signal is received and a second bandwidth corresponding to a second time at which the pilot signal is received, the second time being after the first time; filtering the pilot signal using the second bandwidth; determining a positioning parameter from the pilot signal filtered using the second bandwidth; and determining a position of the mobile device using the positioning parameter.
