Abstract: Embodiments of the present disclosure relate to updating positioning assistance configuration. A first device transmits a first request for updating a current positioning assistance configuration of the first device to a second device. The first device is in a radio resource control inactive mode, and the current positioning assistance configuration is used by the first device to receive a plurality of positioning reference signals from a plurality of positioning devices. Further, the first device receives a first response comprising a requested positioning assistance data for updating the current positioning assistance configuration from the second device. In this way, the first device can maintain being in a power saving mode meanwhile update the positioning assistance configuration in time.

Abstract: A method includes receiving positioning configuration information from a base station or location server while in an RRC_connected mode; transitioning to an RRC_idle or RRC_inactive mode, while saving the positioning configuration information; receiving a reference signal for positioning from the base station; performing positioning measurements, while in the RRC_idle or RRC_inactive mode; and sending a location report to the base station or location server while remaining in the RRC_idle or RRC_inactive mode. A related method includes sending positioning configuration information to a user equipment in an RRC_connected mode; sending the user equipment to RRC_idle or RRC_inactive mode by an RRC suspend procedure; sending a reference signal for positioning to the user equipment; receiving a location report from the user equipment in the RRC_idle or RRC_inactive mode; and forwarding the location report from the user equipment to a location server.

Abstract: Various example embodiments relate to provision of a positioning time gap in a paging procedure. An apparatus may obtain positioning capability information of a device. The positioning capability information may comprise an indication of a first time period for determining a position of the device with first initial positioning data and an indication of a second time period for determining the position of the device with second initial positioning data. A positioning time gap may be determined based on the positioning capability information of the device. The apparatus may transmit a first signal, but refrain from transmitting a second signal for at least a duration of the positioning time gap from the first signal. Apparatuses, methods, and computer programs are disclosed.
