AI Technical Summary

Technical Problem

In the new air interface system, the time-frequency resources of PTRS conflict with the time-frequency resources of periodically transmitted signals, resulting in resource waste and increased air interface overhead.

Method used

The network device determines the PTRS resource of the terminal device and sends the first indication information, indicating the offset information of the PTRS resource, so that the terminal device can determine the second PTRS resource after the offset, thus resolving the resource conflict problem without having to pre-configure multiple sets of PTRS parameter sets.

Benefits of technology

By offset processing, the consistency of PTRS resource quantity, density, and time domain interval is ensured, the phase tracking accuracy and terminal equipment throughput are improved, air interface overhead is reduced, and air interface resources are saved.

Abstract

The embodiments of the present application relate to the technical field of wireless communications, etc. Provided are a communication method, a communication apparatus, a communication system, a communication device, a storage medium, and a program product. The method comprises: a network device determining a first PTRS resource configured for a terminal device, and sending first indication information to the terminal device, wherein the first indication information is used for indicating first offset information, which is used by the terminal device to receive a PTRS over a second PTRS resource, the second PTRS resource being a PTRS resource obtained by applying an offset to the first PTRS resource on the basis of the first offset information. The communication method, the communication apparatus, the communication system, the communication device, the storage medium and the program product provided in the embodiments of the present application can reduce air-interface overheads and save air-interface resources in the process of solving a resource conflict problem regarding a first PTRS resource.
