Abstract: Embodiments of the present disclosure relate to communication in sidelink positioning. According to one aspect of the present disclosure, a second device generates a second PRS for positioning of a first device by using a set of second devices including the second device and transmits the second PRS to the first device. The first device communicates with the set of second devices via a sidelink interface. The second PRS is at least transmitted over a bandwidth occupied by a second set of sidelink data channels from the set of second devices to the first device in a time slot. In this way, an improved transmission of PRS from a supporting device is achieved, and efficient and low latency sidelink based ranging/positioning is allowed.

Abstract: Embodiments of the present disclosure relate to fallback behavior for sounding reference signal (SRS) transmissions. According to embodiments of the present disclosure, a terminal device determines an activation/deactivation on the configured SRS resource in radio resource control (RRC)_INACTIVE state and behaviours of the terminal device depend on the activation/deactivation. In this way, it improves positioning accuracy for terminal devices in RRC-INACTIVE state. Additionally, it can also improve power consumption efficiency by avoiding unnecessary power consumption of the terminal device.

Abstract: Systems, methods, apparatuses, and computer program products for contention-based positioning without requiring device authentication are provided. For example, a method can include sending, by a user equipment, a positioning message to a serving network element in a network that includes multiple network elements including both the serving network element itself and at least one other network element. The positioning message can be sent as a contention-based message. The method can also include receiving, by the user equipment, a positioning response from the serving network element. Content of the positioning response can be contingent on a collision result of the contention-based message.

Abstract: An anchor user equipment is configured to: select a sidelink response time value from a plurality of sidelink response time values configured for the user equipment and a target user equipment; and transmit a positioning reference signal to the target user equipment based at least partly on at least one positioning reference signal transmission parameter associated with the selected sidelink response time value. A target user equipment is configured to: receive a positioning reference signal transmitted by an anchor user equipment; identify at least one positioning reference signal transmission parameter associated with the received positioning reference signal; and determine, based on the at least one positioning reference signal transmission parameter, a sidelink response time value for transmission of the received positioning reference signal by the anchor user equipment, the sidelink response time value being for determining position information for the user equipment.

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses, and computer readable storage media of sidelink positioning enhancements. An apparatus selects, from a resource pool, a part of a slot in time domain for communication of a sidelink reference signal. The apparatus generates sidelink control information (SCI) comprising an indication of the part of the slot. The apparatus then transmits the SCI to a terminal device. By efficient usage of SCI, the resource allocation at sub-slot level can be enabled for sidelink positioning. In this way, sidelink positioning sensing is improved in term of resource reservation. In addition, the sidelink positioning reference signal interference can be reduced.
