Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiver may receive, from a transmitter, an indication of a signature of a reconfigurable intelligent surface (RIS). The receiver may receive a signal that is transmitted by the transmitter and redirected by the RIS. The receiver may receive, from the RIS, a sequence associated with the signature of the RIS indicating that the signal is transmitted using a link associated with the RIS. Numerous other aspects are described.
Claims30
A receiver for wireless communication, comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- receive, from a transmitter, an indication of a signature of a reconfigurable intelligent surface (RIS);
- receive a signal that is transmitted by the transmitter and redirected by the RIS;
- and
- receive, from the RIS and via one or more time domain resources associated with the signal, a sequence associated with the signature of the RIS indicating that the signal is transmitted using a link associated with the RIS, wherein the one or more time domain resources comprise an attenuated amplitude, or
- wherein the signal is superposed by the sequence in the one or more time domain resources.
A reconfigurable intelligent surface (RIS) for wireless communication, comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- receive, from a transmitter, an indication of a signature of the RIS;
- receive a signal that is to be redirected to a receiver using a link that is identified by a sequence associated with the signature of the RIS;
- and
- redirect the signal via one or more time domain resources comprising an attenuated amplitude,
- wherein the sequence associated with the signature of the RIS is transmitted in the one or more time domain resources, or
- redirect the signal via one or more time domain resources, wherein the signal is superposed by the sequence in the one or more time domain resources.
A method of wireless communication performed by a receiver, comprising:
- receiving, from a transmitter, an indication of a signature of a reconfigurable intelligent surface (RIS);
- receiving a signal that is transmitted by the transmitter and redirected by the RIS;
- and
- receiving, from the RIS, a sequence associated with the signature of the RIS indicating that the signal is transmitted using a link associated with the RIS, wherein the signal includes one or more time domain resources with an attenuated amplitude and the sequence is received in the one or more time domain resources.

- receiving an indication of a signature of the RIS;
- and
- receiving a signal that is to be redirected to a receiver using a link that is identified by a sequence associated with the signature of the RIS;
- and
- redirecting the signal via one or more time domain resources comprising an attenuated amplitude,
- wherein the sequence is transmitted in the one or more time domain resources, or
- redirecting the signal via one or more time domain resources, wherein the signal is superposed by the sequence in the one or more time domain resources.
