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 reference signal or a first sounding reference signal (SRS) request;
• obtaining a first signal quality measurement based at least in part on the first transmission;
• 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 reference signal or a second SRS request;
• obtaining a second signal quality measurement based at least in part on the second transmission;
• 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 reference signal or a first sounding reference signal (SRS) request;
• obtain a first signal quality measurement based at least in part on the first transmission;
• 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 reference signal or a second SRS request;
• obtain a second signal quality measurement based at least in part on the second transmission;
• 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.

An apparatus for wireless communication, comprising:

• means for obtaining a first signal quality measurement based at least in part on the first transmission;
• means for 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 reference signal or a second SRS request;
• means for obtaining a second signal quality measurement based at least in part on the second transmission;
• and
• means for 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.
