Abstract: A method including monitoring whether a source cell has configured a terminal and a target cell for a conditional handover of the terminal from the source cell to the target cell; estimating a handover delay period if the source cell configures the terminal and the target cell for the conditional handover, wherein the handover delay period indicates a time period for which, according to a prediction of a likely future movement of the terminal, the terminal will likely not perform the conditional handover to the target cell; and at least one of informing the target cell on the handover delay period; and checking whether the handover delay period is larger than a predefined threshold; and cancelling the conditional handover configuration of the terminal and the target cell if the handover delay period is longer than the predefined threshold.

Abstract: Example embodiments of the present disclosure relate to transmission of control information associated with sidelink positioning reference signal. In an example method, a first terminal device in a radio access network comprises at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the first terminal device to: transmit, to a second terminal device in the radio access network, control information associated with a sidelink (SL) positioning reference signal (PRS) during a SL positioning session for positioning of the second terminal device, using a resource for the control information in a Physical Sidelink Feedback Channel (PSFCH) symbol or in at least one symbol dedicated for the control information. In this way, the first terminal device can efficiently transmit control information to the second terminal device with backward compatibility.

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.
