Reference signal received power based reconfigurable intelligent surface calibration

A reconfigurable intelligent surface (RIS) for wireless communication, comprising:

• one or more memories;
• and
• one or more processors, coupled to the one or more memories, the one or more processors individually or collectively configured to cause the RIS to:
• receive, from a network node, configuration information to configure the RIS to apply a set of RIS patterns associated with one or more calibration codebooks during an RIS calibration procedure;
• apply the set of RIS patterns during the RIS calibration procedure based at least in part on the configuration information;
• and
• receive, from the network node, an indication of an updated data communication codebook, wherein the updated data communication codebook is based at least in part on one or more reference signal received power (RSRP) measurement reports associated with one or more pilot signals that are transmitted during the RIS calibration procedure and while the RIS is applying the set of RIS patterns associated with the one or more calibration codebooks.

A method of wireless communication performed by a network node, comprising:

• transmitting, to a reconfigurable intelligent surface (RIS), configuration information to configure the RIS to apply a set of RIS patterns associated with one or more calibration codebooks during an RIS calibration procedure;
• receiving one or more reference signal received power (RSRP) measurement reports associated with one or more pilot signals that are transmitted during the RIS calibration procedure and while the RIS is applying the set of RIS patterns associated with the one or more calibration codebooks;
• and
• updating a data communication codebook based at least in part on the one or more RSRP measurement reports.
