Abstract: Embodiments of the present disclosure relate to methods, devices, apparatuses, and computer readable medium for positioning measurement report. The method comprises: performing, at a first device and based on a set of measurement parameters, positioning measurements: and reporting, at a reporting instance and to a second device, a first part of the positioning measurements with an indication regarding whether or not the first part of the positioning measurements is to be jointly utilized with a second part of the positioning measurements to estimate a location of the first device, the second part of the positioning measurements being previously reported to the second device. In this way, the UE is capable of providing assistant information about location change, which may in turn improve the positioning accuracy. In addition, unnecessary measurements on all the PRS resources can be avoided, thus such a reporting mechanism can reduce power consumption at the UE.

Abstract: Disclosed are example embodiments of methods and devices for switching between measurement gap and measurement gap-less reception of positioning reference signals. An example embodiment provides user equipment comprising at least one processor and at least one memory including computer program code stored therein. The at least one memory and the computer program code may be configured to, with the at least one processor, cause the user equipment to receive positioning reference signals in a measurement gap-less mode, transmit a first request of switching to a measurement gap mode to a base station and/or a location server, receive a first switching request response from the base station, and receive the positioning reference signals in the measurement gap mode when the first switching request response indicates that the first switching request is approved.

Abstract: Reporting integrity measurement error distribution groups is provided. An apparatus may include at least one processor, and at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to communicate, with a network device, information that may include one or more integrity distribution groups (IDGs) and corresponding distribution parameters. The apparatus may further perform positioning measurements for positioning integrity and determine one of the one or more IDGs based on at least one of the positioning measurements. A report is transmitted to the network device that may include at least one of the positioning measurements or an identifier of the determined IDG.

Abstract: The present disclosure relates to a sidelink (SL) positioning measurement based on a plurality of measurement samples. In particular, a location server requests a receiving (RX) device to report SL positioning measurement that has been made from a plurality of measurement samples. The RX UE requests a transmitting (TX) UE to transmit a plurality of SL positioning reference signals (PRSs) through a plurality of SL PRS resources so that the RX UE can obtain multiple SL positioning measurement samples. In this way, it can improve SL positioning performance. The solution allows for high accuracy measurements and hence enables high accuracy SL positioning.
