Abstract: When cell system information changes, a first terminal device receives, during on duration of the first terminal device, system information sent by a second terminal device, so that the first terminal device can receive the system information through a sidelink between the first terminal device and the second terminal device without a need to maintain a cellular link, thereby reducing complexity and power consumption of system information transmission. Alternatively, when cell system information changes and a first terminal device has only one receive radio frequency chain, the first terminal device obtains system information within a gap period of communication between the second terminal device and the first terminal device through a link between the first terminal device and a network device, so that the first terminal device maintains a cellular link only within the gap period, thereby reducing complexity and power consumption of system information transmission to some extent.

Abstract: A method, device and system are provided for a user equipment positioning. In an embodiment, a central device of a radio access network (RAN) node, which comprises the central device and at least two distributed devices, receives positioning measurement request information from a location management function (LMF) device. The central device separately sends uplink signal configuration information to a first distributed device and a second distributed device of the at least two distributed devices in application protocol signaling The first and two distributed devices measure an uplink signal sent from a user equipment, and the two distributed devices separately sends a uplink signal measurement result in an application protocol signaling to the central device. The central device sends a positioning measurement result comprising the two uplink signal measurement results to the LMF device.

Abstract: A device-to-device (D2D) communication method and a D2D terminal device, where the method includes determining, by a first device, a time that the first device is out of coverage of a synchronization source after leaving the coverage of the synchronization source determining, by the first device, target timing based on the time, and performing, by the first device, D2D communication based on the target timing. Hence, the target timing can be selected more accurately for the first device.
