1. A method comprising:
receiving, by a terminal, first configuration information related to mapping between at least one uplink reference signal (UL RS) and at least one downlink reference signal (DL RS) from a base station;
receiving, by the terminal, second configuration information related to a plurality of spatial parameter candidates for uplink transmission from the base station; and
performing, by the terminal, uplink transmission in N transmission occasions (TO) based on at least one of N (N is an integer greater than 1) default uplink spatial parameters or N default pathloss reference signals (PL RS);
wherein the N default uplink spatial parameters are associated with the N TOs, respectively, and the N default PL RSs are associated with the N TOs, respectively;
wherein a default uplink spatial parameter for a specific TO among the N TOs is one spatial parameter specified by a predefined rule among the plurality of spatial parameter candidates based on the second configuration information, or an UL RS mapped to the one spatial parameter based on the first configuration information; and
wherein based on the plurality of spatial parameter candidates related to the second configuration information being a plurality of UL RSs,
the default uplink spatial parameter for the specific TO is one UL RS specified by the predefined rule among the plurality of UL RSs, and the default PL RS is one DL RS mapped to the one UL RS based on the first configuration information.
