Abstract: This application discloses a reference signal configuration determining method and apparatus. The method includes: A network device determines a first configuration for sending an aperiodic reference signal by a to-be-positioned terminal; and the network device sends the first configuration to a location management function. The network device is a serving base station of a terminal. The serving base station of the terminal may determine an aperiodic reference signal configuration of the terminal at any time. The first configuration of the aperiodic reference signal is sent to the location management function, so that the location management function can be notified of the aperiodic reference signal configuration in time. In this way, the location management function obtains positioning measurement information from a measurement network element based on the first configuration. Consequently, an uplink positioning technology is optimized and uplink positioning accuracy is improved.

Abstract: The present disclosure relates to wireless communication methods, terminal devices, and network devices. In one example method, a network device sends timing advance timer (TAT) configuration information to a terminal device, where the TAT configuration information is used by the terminal device to configure duration of a TAT. The terminal device receives the TAT configuration information sent by the network device. The terminal device configures the TAT based on the TAT configuration information, and asynchronously sends uplink data to the network de vice based on a running status of the TAT. The network device receives the uplink data sent by the terminal device based on the TAT configuration information.
