30 Claims

1. An apparatus for wireless communication comprising:

at least one memory; and

at least one processor coupled to the at least one memory, wherein the at least one processor is configured to:

receive, from a network device via a reconfigurable surface, a set of reference signals reflected by the reconfigurable surface via a set of precoder configurations, wherein the set of reference signals are transmitted within a set of reference signal occasions of a sweep procedure associated with a configuration of the reconfigurable surface with different precoder configurations of the set of precoder configurations for reflection of signals;

transmit, to the network device via the reconfigurable surface, a feedback message comprising an indication of at least one precoder configuration of the set of precoder configurations based at least in part on reception of the set of reference signals, wherein the at least one precoder configuration comprises a plurality of precoders for the reconfigurable surface; and

receive, from the network device via the reconfigurable surface, a downlink transmission based at least in part on transmission of the feedback message.
