摘要： A wireless device and a method therein for receiving positioning system information from a radio network node. The wireless device and the radio network node operate in a wireless communications network. The wireless device receives positioning system information broadcast scheduling information comprising information about positioning System Information Blocks that are comprised in a System Information message. Further, the wireless device receives an indication that a pSIB is segmented into pSIB segments. Based on the indication and on the pSI the wireless device determines whether or not the pSIB segments are scheduled via contiguous scheduling. When the pSIB segments are determined to be scheduled via contiguous scheduling, the wireless device monitors scheduled resources, retrieves the contiguously scheduled pSIB segments and decodes position system information of the retrieved pSIB segments.

摘要： Systems and methods for System Frame Number (SFN) Frame Time Difference (SFTD) reporting are disclosed. Embodiments of a method of operation of a User Equipment (UE) in a wireless network to perform SFTD measurements between a Primary Cell (PCell) of the UE and one or more other cells is provided. In some embodiments, the method comprises receiving, from a network node in the wireless network, a list of cells for which the UE can report SFTD measurements. The method further comprises performing SFTD measurements and reporting the SFTD measurements in accordance with the list of cells for which the UE can report SFTD measurements. In this manner, SFTD reporting is provided in an efficient manner.

摘要： Systems and methods for positioning in a cellular communications system are disclosed. A method performed by a first base station (BS) includes receiving a signal transmitted by a second BS and estimating a Time of Arrival (TOA) of the received signal at the first BS according to a clock of the first BS. The method further includes determining a delta value that is or is a function of a time between the TOA of the received signal at the first BS according to the clock and a time reference at the first BS and either (a) providing the delta value to a positioning estimation entity within the communications system or (b) using the delta value at the first BS to reduce a time synchronization error between the first BS and the second BS, or (c) passing the delta value to a User Equipment.

摘要： The disclosure relates to an OTDOA positioning technique wherein different base stations transmit different variations of the same basic PRS or other positioning signal synchronously as an SFN signal to effect an observed time shift at the UE between the different variations of the basic PRS signal or positioning signal. This added time shift resulting from the transmission of different variations by different base stations effectively spreads the corresponding channel impulses in the CIR of the SFN signal in the time domain so that the UE is better able to detect and discriminate between different instances of the positioning signal transmitted from different base stations.

摘要： A method performed by a server for assisting a radio network node to handle a set of positioning assistance data for positioning one or more User Equipments, UEs, in a wireless communications network is provided.
Based on importance, the server determines a priority associated to the respective positioning assistance data out of the set of positioning assistance data.
The server assists the radio network node by sending the set of positioning assistance data, and information about the determined priority associated to the respective positioning assistance data. The determined priority enables the radio network node to determine a schedule for broadcast of at least some of the respective positioning assistance data out of the set of positioning assistance data, in respect to available resources in the radio network node.-
