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.

摘要： A network node (44) assists a user equipment (36) to perform positioning measurements on positioning signals (46) transmitted by one or more cells during respective positioning occasions of those cells. The node (44) selectively delays transmission of assistance data to the user equipment (36) as needed, based on defined uncertainty in one or more timing parameters, for the network node (44) to identify with certainty between which two consecutive positioning occasions of a reference cell the user equipment (36) will receive that assistance data. The node (44) correspondingly generates the assistance data to be transmitted to indicate positioning occasion timing for at least one cell relative to the latter of those two consecutive positioning occasions of the reference cell. Such calculation and transmission enables the user equipment (36) to be certain that the next reference cell positioning occasion occurring after its reception of the assistance data is the reference cell positioning occasion on which the assistance data is based.

摘要： A base station (40-s) is configured to serve a wireless device (36) in a serving cell (42-s) on a serving frequency. The base station (40-s) obtains information that indicates one or more non-serving frequencies on which the device (36) is to perform one or more positioning measurements. These positioning measurements are to be used for determining the device's geographic position. For at least one non-serving frequency indicated by the information, the base station (40-s) configures a measurement gap during which the device (36) is to perform a corresponding positioning measurement. Specifically, the base station (40-s) configures such measurement gap to occur during a period of time in which a neighboring eel! (42-1, 42-2) transmits a positioning reference signal over that non -serving frequency. A positioning reference signal is specifically designed to be a signal on which a device performs positioning measurements. Thus, by aligning the measurement gap with a positioning reference signal, the positioning measurements will prove more reliable and accurate.

摘要： The present invention provides a method and apparatus for autonomously detecting whether a reference signal within an OFDM signal transmitted by a remote transmitter is or is not muted for a given transmission time. Muting or puncturing may be applied to all or only a portion of the reference signal. The method, which may be carried out in an appropriately configured radio apparatus, includes receiving the OFDM signal and calculating a first comparison metric from signal samples of the OFDM signal corresponding to a first set of resource elements of the OFDM signal, and calculating a second comparison metric from signal samples of the OFDM signal corresponding to a second set of resource elements of the OFDM signal. The method continues with determining whether the reference signal is or is not muted for the given transmission time, by comparing the first and second comparison metrics, and foregoing or performing reference signal measurements responsive to determining that the reference signal is or is not muted.
