Signal quality measurements for identifying intelligent reflection surfaces

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

• transmitting, to a user equipment (UE) and via at least one beam of the network node and via a first subset of a plurality of intelligent reflection surfaces (IRSs), a first transmission,
• the first transmission comprising a first sounding reference signal (SRS) request;
• receiving, from the UE, a first SRS associated with the first SRS request;
• obtaining a first signal quality measurement based at least in part on the first transmission, wherein the first signal quality measurement comprises a first reference signal received power (RSRP) associated with the first SRS;
• transmitting, to the UE and via the at least one beam and via a second subset of the plurality of IRSs, a second transmission,
• the second transmission comprising a second SRS request;
• receiving, from the UE, a second SRS associated with the second SRS request;
• obtaining a second signal quality measurement based at least in part on the second transmission, wherein the second signal quality measurement comprises a second RSRP associated with the second SRS;
• and
• identifying at least one IRS of the plurality of IRSs based at least in part on the first signal quality measurement and the second signal quality measurement.

A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a network node, cause the network node to:
• transmit, to a user equipment (UE) and via at least one beam of the network node and via a first subset of a plurality of intelligent reflection surfaces (IRSs), a first transmission,
• the first transmission comprising a first sounding reference signal (SRS) request;
• receive, from the UE, a first SRS associated with the first SRS request;
• obtain a first signal quality measurement based at least in part on the first transmission, wherein the first signal quality measurement comprises a first reference signal received power (RSRP) associated with the first SRS;
• transmit, to the UE and via the at least one beam and via a second subset of the plurality of IRSs, a second transmission,
• the second transmission comprising a second SRS request;
• receive, from the UE, a second SRS associated with the second SRS request;
• obtain a second signal quality measurement based at least in part on the second transmission, wherein the second signal quality measurement comprises a second RSRP associated with the second SRS;
• and
• identify at least one IRS of the plurality of IRSs based at least in part on the first signal quality measurement and the second signal quality measurement.
