Abstract
A method for sending a signal, performed by a reconfigurable intelligent surface (RIS) array, includes: determining a mapping relationship between an active RIS array element in the RIS array and a time-frequency resource; sending the mapping relationship to a user equipment (UE); and sending a pilot signal to the UE by mapping the pilot signal sent by the active RIS array element to the time-frequency resource corresponding to the active RIS array element.
Claims26
A method for sending a signal, performed by a reconfigurable intelligent surface (RIS) array, comprising:
- determining a mapping relationship between an active RIS array element in the RIS array and a time-frequency resource;
- sending the mapping relationship to a user equipment (UE);
- and
- sending a pilot signal to the UE by mapping the pilot signal sent by the active RIS array element to the time-frequency resource corresponding to the active RIS array element.

A method for sending a signal, performed by a UE, comprising:
- obtaining a mapping relationship sent by an reconfigurable intelligent surface (RIS) array;
- and
- obtaining a pilot signal, sent by an active RIS array element in the RIS array, from a time-frequency resource according to the mapping relationship.

A reconfigurable intelligent surface (RIS) array comprising:
- a processor;
- and
- a memory having stored therein a computer program that, when executed by the processor, causes the RIS array to implement:
- determining a mapping relationship between an active RIS array element in the RIS array and a time-frequency resource;
- sending the mapping relationship to a user equipment (UE);
- and
- sending a pilot signal to the UE by mapping the pilot signal sent by the active RIS array element to the time-frequency resource corresponding to the active RIS array element.
