摘要： A method in a first network node (105) for estimating a first timing offset difference between a first timing offset of a first base station and a second timing offset of a second base station, is provided. The first network node (105) receives Uplink Time Difference Of Arrival, UTDOA, measurements. The UTDOA measurements relate to a first UTDOA time difference. The first network node (105) further receives Observed Time Difference Of Arrival, OTDOA, measurements. The OTDOA measurements relate to a first measured OTDOA time difference. The first network node estimates a first timing offset difference between a first timing offset of the first base station and a second timing offset of the second base station based on the first UTDOA time difference and the first measured OTDOA time difference.

摘要： Techniques are disclosed for determining measurement uncertainty of and/or multipath effects on positioning measurements, based on the residual deviations between timing measurements and high-accuracy location results. An example method begins with collecting (510) a plurality of timing measurements or ranging measurements, or both, each measurement corresponding to at least one anchor node antenna having a known location. A measurement deviation is determined (520) for each measurement by comparing the measurement to a corresponding reference location. The measurement deviations are used (530) to estimate measurement quality for one or more subsequent positioning measurements, and/or uncertainty associated with one or more subsequent positioning estimates, and/or an effect of multipath on subsequent positioning measurements or estimates. In some embodiments, a covariance matrix is calculated from the measurement deviations and is used to determine statistical information or multipath effects for measurements corresponding to a particular one of the anchor node antennas.

摘要： A user equipment (36) herein resolves timing ambiguities associated with when the user equipment (360 is to perform assisted positioning measurements. The user equipment (36) receives assistance data that indicates positioning occasion periodicities of a first cell and a reference cell, and that indicates a positioning occasion timing offset between those cells. The user equipment (36) performs signal detection at candidate timing offsets surrounding the indicated positioning occasion timing offset, to determine which candidate timing offset has the greatest probability of being the actual positioning occasion timing offset between the first cell and the reference cell. The user equipment (36) may then time assisted positioning measurements for the first cell based on the candidate timing offset determined as most likely being the actual timing offset, rather than necessarily timing those measurements based on the offset indicated in the assistance data.
