Abstract: A signal sending method includes generating M signals. The signal sending method also includes sending the M signals on M time-frequency resource elements. The M signals are in a one-to-one correspondence with the M time-frequency resource elements. At least two of the M time-frequency resource elements overlap in a frequency domain. Any two of the M time-frequency resource elements are free from overlapping in a time domain. M is an integer greater than 1.

Abstract: A method for controlling positioning integrity. A location management device receives a first message sent by a terminal device, where the first message includes a first parameter set. The first parameter set includes measurement information and/or error information relating to location information of the terminal device. The error information is related to the positioning integrity. The location management device obtains a first positioning result based on the first parameter set and/or positioning assistance data. The first positioning result includes location information and/or integrity information of the terminal device. The integrity information includes the error information and/or alarm information, and the alarm information includes a determining result obtained by comparing the first positioning result with a preset determining condition.

Abstract: A communication method includes receiving, by a terminal device or a chip in the terminal device, first configuration information, and sending n sounding reference signals based on the first configuration information. The first configuration information is useable to configure n sounding reference signals. The n sounding reference signals are useable for positioning. A carrier corresponding to at least one of the n sounding reference signals is a first positioning carrier, where n is an integer greater than 1. The n sounding reference signals are included in a same time domain resource unit.

Abstract: A method includes obtaining, by a positioning device, positioning integrity information of a terminal device from an access network device or the terminal device. The positioning integrity information indicates a positioning integrity requirement that is predicted by the access network device or the terminal device and that is of the terminal device in a first scenario. The method also includes performing, by the positioning device based on the positioning integrity information, an operation for positioning the terminal device, to meet the positioning integrity requirement of the terminal device in the first scenario.

Abstract: The technology of this application relates to a positioning method and apparatus. In one example embodiment, a network server can receive N pieces of phase information sent by a first communication device, where the N pieces of phase information are obtained based on one or more reference signals sent by a second communication device, and then determine a distance between the first communication device and the second communication device based on the N pieces of phase information. According to the positioning method provided in this application, measurement accuracy of the measured distance between the first communication device and the second communication device can be improved.
