Abstract: Embodiments of the present disclosure relate to positioning. A first device performs positioning measurements of a first set of reference signals in a first frequency range. If the first device determines that quality of service requirements for positioning the first device are satisfied, the first device transmits a first measurement report to a second device. The first measurement report only comprises a first set of measurement results associated with the first set of reference signals.

Abstract: Embodiments of the present disclosure relate to methods, devices, apparatuses, and computer readable medium for positioning enhancement mechanism. A first device determines that a third device is to transmit a positioning related message in a non-connected state. The first device transmits assistance information to a second device serving the third device. The assistance information comprises at least one of data size and a transmission periodicity for the positioning related message. By means of the assistance information, the base stations are provided with proactive knowledge of the positioning related message. In this way, the base station is capable of determining appropriate configurations for the SDT procedure. The terminal device may then transmit the positioning related message in the RRC NON-CONNECTED state via the SDT. As such, the efficiency of SDT procedure can be improved, while avoiding segmentation or subsequent transmission of the positioning report.

Abstract: Embodiments of the present disclosure relate to a method, device, apparatus and computer readable medium for sidelink transmission. According to embodiments of the present disclosure, a first device determines a target transmission start position from a set of candidate transmission starting positions in a sidelink slot based on an access level of a sidelink transmission to be performed. The first device performs a LBT before the target transmission starting position. If the LBT is successful, the first device performs the sidelink transmission from the target transmission starting position. In this way, it enables the use on Mode 2 in shared/unlicensed spectrum, while addressing the issues of un-sensed (not detected) SPS transmissions due to LBT failure as well as making mode 2 more robust towards LBT failures due to other coexisting systems.

Abstract: Example embodiments of the present disclosure relate to coordinated positioning via sidelink resource. A first terminal device transmits a first message to a plurality of positioning terminal devices including a second terminal device. The first message indicates sidelink resources for transmitting reference signals from the plurality of positioning terminal devices to the first terminal device. Upon receiving the first message, the second terminal device determines a first sidelink resource for transmitting a first reference signal for positioning the first terminal device from the sidelink resources, and then transmits the first reference signal via the first sidelink resource to the first terminal device. Through this solution, a sidelink-based positioning solution can be implemented. In particular, even in the scenario of being partial coverage or being out of coverage, where at least part of the devices involved in the positioning procedure cannot access the network device, the resource allocation for transmitting RSs can be implemented.

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: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of PRS design for low power tracking The method comprises receiving from a second device an indication that a Sounding Reference Signal, SRS, is to be used for a positioning process of the first device unless a further indication is received; and transmitting a SRS to a third device and a fourth device, the third device being responsible for measuring a position of the first device in the positioning process. In this way, a SRS can be applied for multiple cells and the handover can be avoided or SRS resources re-configuration can be avoided even if the handover occurs at the UE. The power consumption and the positioning latency of the UE can be reduced. Meanwhile, the signalling overhead to setup RRC connection may also be reduced.

Abstract: Disclosed are methods for determining channel access for uplink transmissions. An example method (200) may include determining (210) a duration of a gap between an uplink transmission of a first apparatus and a downlink transmission of a second apparatus before the uplink transmission and in a channel occupancy time of the second apparatus in a case where the uplink transmission falls within the channel occupancy time, and determining (220) at least one of a channel access type and a cyclic prefix extension for the uplink transmission according to the duration of the gap. Related apparatuses and computer readable media are also disclosed.

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of channel access procedure based on the channel access priority class (CAPC). The method comprises receiving scheduling information from a second device, the scheduling information at least indicating resources allocated for a transmission from the first device to the second device, a channel access type for the transmission and an expected access priority for the transmission. The method further comprises comparing the expected access priority with an access priority of data in a buffer of the first device and determining use of the resources based on the comparison. In this way, the Channel Occupancy Time (COT) sharing can be used only for the data with higher or equal priority to avoid unintended usage of the grant on unlicensed band and coexistence fairness among nodes with different types of traffic to be transmitted may be achieved.
