18. A method of wireless communication by a first device, comprising:
performing a first transmission using a first set of beams of the first device in response to an activated reconfigurable intelligent surface (RIS) for serving a second device to facilitate communication between the first device and the second device is not being present; and
performing a second transmission using a second set of beams of the first device in response to the activated RIS is being present, the second set of beams being a subset of the first set of beams that excludes one or more beams of the first set of beams.
