Abstract: A method includes obtaining a first power measurement associated with resource blocks (RBs) being utilized by a terminal device (TD). The method includes determining whether the first power measurement satisfies a first threshold. The method includes, upon determining that the first power measurement satisfies the first threshold, transmitting, to a target TD, a positioning reference signal (PRS). The method includes, determining whether the first power measurement does not satisfy the first threshold and, in response, determining a set of comb parameters. The method includes obtaining, based on the set of comb parameters, a second power measurement associated with resource elements (REs) related to the RBs. The method includes determining whether the second power measurement satisfies a second threshold. The method includes, upon determining that the second power measurement satisfies the second threshold, transmitting, based on the set of comb parameters, the PRS to the target TD.

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.
