WIPO Patent Application WO/2023/077525
Kind Code:
A1
Abstract:
A signal sending method and apparatus, and a user equipment, an RIS array and a storage medium, which belong to the technical field of communications. The method comprises: an RIS array determining a mapping relationship between active RIS array elements in the array and time-domain resources; sending the mapping relationship to a UE; and mapping pilot signals, which are sent by the active RIS array elements, to the time-domain resources corresponding to the active RIS array elements, so as to send the pilot signals to the UE. By means of the present method, the transmission stability of pilot signals can be ensured, thereby ensuring the precision of channel estimation.
