Abstract: A method for a base station includes sending a request for a report on beamforming capability to a target user equipment; receiving the report on the beamforming capability from the target user equipment; allocating at least one positioning reference signal resource for use by the target user equipment based on at least the capability information included in the report; determining a beam sweeping mle based on the at least one positioning reference signal resource allocated for the target user equipment; and sending the positioning reference signal resource allocation and the beam sweeping mle to the target user equipment. A corresponding method for a user equipment includes receiving a request for a report on beamforming capability from a serving base station; sending the report on the beamforming capability to the serving base station; receiving information relating to at least one positioning reference signal resource and a beam sweeping rule from the serving base station; and performing beam sweeping on uplink positioning reference signal transmissions using the received positioning reference signal resource allocation based on the beam sweeping rule.

Abstract: Various example embodiments relate to methods and apparatuses for positioning reference signal configuration and measurement update. An apparatus in a communication network may be configured to transmit to a location server in the communication network information of one or more non-preferred resources for positioning reference signal, PRS, measurement at a terminal device in the communication network, and receive a positioning configuration related indication from the location server. The positioning configuration related indication is obtained in connection with the transmitted information and it indicates the apparatus to update a positioning configuration to reduce PRS measurement of the terminal device on the one or more non-preferred resources.

Abstract: Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of channel coordination in the unlicensed spectrum. The method comprises receiving, at a first device and from a plurality of second devices, information about carrier sensing to be performed by the plurality of the second devices; determining a transmission pattern for a target second device of the plurality of the devices based on the information about the carrier sensing and information about time sensitive traffic of the plurality of the second devices, the transmission pattern including at least a sensing period for transmission of time sensitive traffic of the target second device and a muting period of the target second device; and transmitting a first message indicative of the transmission pattern to the target second device. In this way, the interoperability of the TSN network device and the normal network device can be efficiently improved in an industrial automation scenario. By controlling the access/transmission of the TSC traffic in the TSC dedicated transmission period, the TSC traffic of the target network device can be protected and the latency requirements can be satisfied.

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: 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.
