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: In some embodiments, there is disclosed a method that includes determining, for a transmit timing error group of one or more antennas, an indicator of whether a common transmit timing error that is within in a threshold margin is to be used to characterize the one or more antennas; and reporting the indicator to a network node to enable a determination of whether to perform a time error calibration on one or more measurements performed on one or more reference signal resources. Related systems, methods, and articles of manufacture are also disclosed.

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.

Abstract: Embodiments of the present disclosure relate to a transmit beamforming for positioning. A location management device generates information regarding an angle of departure, the angle of departure being expected for transmission of reference signals for positioning and transmits the information to a device transmitting the reference signals. The device may determine a transmit beamforming solution for transmitting the reference signals based on the angle of departure. In this way, power savings can be achieved due to decreased reference signal overhead. Further, positioning accuracy can be improved through appropriately beamformed reference signal transmissions.
