Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of the acknowledgement feedback for a positioning in RRC inactive state. The method comprises receiving, at a first device in a radio resource control, RRC, inactive state, information at least indicating a latency requirement for the first device to transmit an acknowledgement feedback for a reception of a message, the message being associated with a positioning of the first device and transmitted from a second device or a fourth device to the first device; and performing the transmission of the acknowledgement feedback for the reception of the message at least based on the information without changing the RRC inactive state. With the solution of the present disclosure, acknowledgement information report can be enabled to guarantee the reliability of positioning assistance data reception. It is benefit for the UE in the aspect of power saving, end-to-end positioning latency reduction and signaling overhead reduction.

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.

Abstract: Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for positioning based on a plurality of measurement reports. In example embodiments, a first device performs measurement of a first subset of positioning reference signals (PRSs) from a set of PRSs. Based on the measurement of the first subset of PRSs, the first device generates a measurement report and sends the measurement report to a second device along with a report indication that the measurement report is generated based on measurement of a subset of PRSs from the set of PRSs. In this way, the measurement report latency may be reduced significantly.

Abstract: Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for priority adaptation of a positioning reference signal (PRS). In example embodiments, a first device receives, from a second device, an indication associated with a change of a priority level for transmitting a positioning reference signal. Based on the received indication, the first device changes the priority level for transmitting the positioning reference signal.

Abstract: Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of the adjustment of the Timing Advance (TA). The method comprises determining a channel occupancy time structure for accessing a radio channel between the first device and a second device, the channel occupancy time structure indicating a set of time-domain resources for accessing the radio channel; and setting a timing advance for a transmission from the first device to the second device based on the channel occupancy time structure. In this way, a dynamic adjustment of TA is allowed at the UE, which ensures that a desire duration of the gaps of the channel occupancy at different transmission scenarios.

Abstract: Methods and apparatus for transmitting positioning measurement report are provided. The method includes a step of receiving a location information request from a serving base station or from a location server, a step of determining timing for transmitting a positioning measurement report, a step of generating a report assisted message based on the determined timing for transmitting the positioning measurement report, and a step of transmitting the report assisted message to the serving base station. The key idea of this disclosure is requesting UL resources for positioning measurement report in advance by transmitting a report assisted message. Consequently, the UE can transmit the positioning measurement report just after the measurement data being generated. The disclosure can minimize the delay from positioning measurement data generation to the positioning measurement report.
