Abstract: A reference signal configuration determining method and apparatus are provided. 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. According to the application, the location management function obtains positioning measurement information from a measurement network element based on the first configuration, thereby optimizing an uplink positioning technology and improving uplink positioning accuracy.

Abstract: This application provides a signal transmission method and apparatus. The method includes: A neighboring cell sends downlink reference signal resource configuration information to a serving cell. The serving cell sends a downlink reference signal measurement request including downlink reference signal resource configuration information to a terminal device. The neighboring cell and the terminal device transmit a downlink reference signal based on the downlink reference signal resource configuration information. The terminal device obtains a downlink reference signal measurement result. The terminal device sends the downlink reference signal measurement result to the serving cell. The serving cell sends the downlink reference signal measurement result to the neighboring cell, or sends, to the neighboring cell, beam information that is about a beam between the neighboring cell and the terminal device and that is determined based on the downlink reference signal measurement result.

Abstract: A signal transmission method and an apparatus. The method includes: a location management device receives first SRS resource configuration information from a serving cell and/or a neighboring cell. The location management device sends second SRS resource configuration information to a terminal device, where the second SRS resource configuration information includes third SRS resource configuration information and a downlink reference signal associated with an SRS resource indicated by the third SRS resource configuration information, and the third SRS resource configuration information is a part or all of the first SRS resource configuration information. The location management device configures the SRS resource for the terminal device, so that the SRS resource can be associated with the downlink reference signal. This helps the terminal device obtain information about a transmission beam for sending an SRS, and therefore SRS receiving efficiency of the cell can be improved to some extent.

Abstract: The present disclosure relates to reference signal resource configuration methods and apparatus. In one example reference signal resource configuration method, a terminal receives sounding reference signal (SRS) resource configuration information from a base station. In response to determining that at least two SRS resources indicated by the SRS resource configuration information are located on a same orthogonal frequency division multiplexing (OFDM) symbol, the terminal maps one of the at least two SRS resources to the OFDM symbol.
