  • Publication number: 20210385618
    Abstract: 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.

  • Publication number: 20210373116
    Abstract: 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.

  • Patent number: 11184228
    Abstract: A configuration controller (60) is provided to make changes to configuration of a communications network (10) having VNFs used in providing services to UEs. If the change could affect a service using a first VNF (30), if made while that VNF is in use, a substitute VNF (32) is instantiated corresponding to that first VNF. The first UE is transferred to use the substitute VNF instead of the first VNF. The proposed change to the configuration is made with respect to either one of these VNFs, while the service to the first UE is maintained using the other one of these VNFs. If needed all VNFs and a service area can be substituted. Thus, such configuration changes no longer need to await a quiet period when few or no UEs are attached, and enable the configuration changes to be made more rapidly, responsive to changing circumstances.

  • Publication number: 20210337508
    Abstract: 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.

  • Patent number: 11129126
    Abstract: Embodiments herein relate to a method performed by a first communication node (110; 121) for determining the position (of a second communication node (122) in a wireless communications network (100). The first communication node (110; 121) transmits a timing measurement message to the second communication node (122) as a beamformed transmission based on channel sounding feedback information received from the second communication node (122). The first communication node (110; 121) also receives an acknowledgement message from the second communication node (122) for the timing measurement message in the beamformed transmission. Furthermore, the first communication node (110; 121) determines the position of the second communication node (122) at least partly based on a transmission time of the timing measurement message and a reception time of the acknowledgement message. Embodiments of the first communication node (110; 121) are also described. Embodiments herein also relate to a second communication.
