Reconfigurable intelligent surface co-existence

An apparatus for wireless communication at a first wireless communications device, comprising:

• a processor;
• and
• memory coupled with the processor, the memory comprises instructions executable by the processor to cause the apparatus to:
• receive, from a second wireless communications device, a signal that is indicative of a phase-change pattern applied to communications between the first wireless communications device and the second wireless communications device by a reconfigurable intelligent surface reflecting the communications;
• determine the phase-change pattern from the signal;
• and
• transmit a message to the second wireless communications device, wherein at least one of a content or a transmission property of the message is based at least in part on the phase-change pattern.
