Ranging method and ranging apparatus

A ranging method, comprising:

• transmitting, by a network device, a first timing advance (TA) corresponding to a terminal device, wherein the first TA is used for determining first distance information about the terminal device based on a TA quantization interval corresponding to the first TA, and the first distance information comprises a first distance between the terminal device and the network device;
• and
• transmitting, by the network device, indication information related to second distance information about the terminal device, wherein the second distance information is determined based on second TA, and a TA quantization interval corresponding to the second TA is less than the TA quantization interval corresponding to the first TA,
• wherein the first distance information and the second distance information are used for performing distance measurement on the terminal device.

An apparatus, comprising:

• at least one processor;
• one or more non-transitory computer-readable storage media coupled to the at least one processor and storing programming instructions for execution by the at least one processor, wherein the programming instructions, when executed, cause the apparatus to perform operations comprising:
• receiving a first timing advance (TA) corresponding to a terminal device;
• determining first distance information about the terminal device based on the first TA and a TA quantization interval corresponding to the first TA, wherein the first distance information comprises a first distance between the terminal device and a network device;
• determining second distance information about the terminal device;
• and
• performing distance measurement on the terminal device based on the first distance information and the second distance information,
• wherein the second distance information is determined based on one or more of following:
• a path loss corresponding to the terminal device;
• or
• a second TA, wherein a TA quantization interval corresponding to the second TA is less than the TA quantization interval corresponding to the first TA.
