Method and apparatus for transmitting and receiving signal in wireless communication system

An apparatus comprising:

• at least one transceiver for transmitting and receiving a wireless signal;
• and
• at least one processor for controlling the at least one transceiver,
• wherein the at least one processor configured to:
• receive first information for configuring a plurality of spatial parameters for a plurality of signals;
• receive second information for indicating a spatial parameter for a downlink signal based on the first information;
• and
• receive the downlink signal based on the second information,
• wherein, based on at least one signal of the plurality of signals being configured to refer to a reference signal related to a spatial parameter of the downlink signal prior to reception of the second information, a spatial parameter for the at least one signal is updated to be identical to the spatial parameter for the downlink signal.
