1. A reconfigurable intelligent surface (RIS), comprising:
multiple antenna elements;
a memory configured to store instructions; and
one or more processors communicatively coupled with the memory, wherein the one or more processors are configured to:
receive a radio resource control (RRC) signal indicating a default configuration to apply to the multiple antennas;
receive a first configuration having a time interval for applying the first configuration to reflect signals from a network node;
apply the first configuration to the multiple antenna elements for the time interval; and
apply, based on expiration of the time interval, the default configuration, that is different from the first configuration, to the multiple antenna elements.
