Description

Information indication method, device, communication equipment and storage medium

Technical Field

The present disclosure relates to the field of wireless communications, and in particular, to an information indication method, an apparatus, a communication device, and a storage medium.

Background

In Non-terrestrial networks (NTN, non-Terrestrial Networks), signal coverage of some channels is limited due to the large distance between the satellite or aerial device and the ground terminal and the large path loss. For example, coverage of the physical uplink shared channel (PUSCH, physical Uplink Shared Channel) may be limited. In a related scenario, the coverage of the channel may be improved by demodulation reference signal (DMRS, demodulation Reference Signal) bundling. DMRS bundling defines a nominal time domain window (TDW, time Domain Window) and an actual TDW within which the terminal maintains power consistency and phase continuity. However, in NTN, the constant movement of the satellite may cause the distance between the terminal and the satellite to vary, and the terminal may autonomously adjust Timing Advance (TA), which may deteriorate power consistency and phase continuity.
