Description

CROSS-REFERENCE TO RELATED APPLICATION This application is a national phase of International Application No. PCT/CN2020/120483, filed on Oct. 12, 2020, the entire content of which is incorporated herein by reference. TECHNICAL FIELD The disclosure relates to the field of wireless communication technologies but is not limited to the field of wireless communication technologies, and in particular, to a method and an apparatus for requesting a positioning reference signal (PRS) configuration, a communication device, and a storage medium. BACKGROUND The 5th generation (5G) mobile communication technology in the release 16 (R16) introduces various terminal positioning technologies, all of which can realize the terminal positioning. When a network needs to position a terminal, a location management function (LMF) sends a positioning request to the terminal. After receiving the positioning request, the terminal completes a positioning measurement of a positioning reference signal (PRS) according to information carried in the positioning request, and reports a positioning measurement result or location information of the terminal, to complete a positioning process of the terminal. SUMMARY According to a first aspect of the disclosure, a method for requesting a PRS configuration is provided. The method is applicable to a first communication node. The method includes: sending a message carrying a suggested PRS configuration, in which the suggested PRS configuration is a PRS configuration suggested by the first communication node for terminal positioning. According to a second aspect of the disclosure, a method for requesting a PRS configuration is provided. The method is applicable to a second communication node. The method includes: receiving a message carrying a suggested PRS configuration, in which the suggested PRS configuration is a PRS configuration suggested for terminal positioning. According to a third aspect of the disclosure, a method for requesting a PRS configuration is provided. The method is applicable to a third communication node. The method includes: receiving a message carrying a target PRS configuration for a terminal to perform positioning measurement, in which the target PRS configuration is determined according to a suggested PRS configuration. According to a fourth aspect of the disclosure, a communication device is provided. The communication device includes: a processor; and a memory for storing processor-executable instructions. The processor is configured to execute the executable instructions, to perform the method described above. According to a fifth aspect of the disclosure, a non-transitory computer storage medium is provided. The computer storage medium stores a computer-executable program, and when the executable program is executed by a processor, the method described above in the disclosure is performed.
