1. A method comprising:
receiving, by a terminal from a network, downlink control information (DCI) scheduling an uplink physical channel or a downlink physical channel in a first cell, wherein the DCI includes first information related to a scheduled cell, and second information related to a spatial parameter for the uplink physical channel or the downlink physical channel to be scheduled; and
based on the DCI, performing, by the terminal, the uplink physical channel transmission or the downlink physical channel reception in the scheduled cell,
wherein the first information and the second information are jointly encoded by one or more fields included in the DCI, and
wherein the spatial parameter for the uplink physical channel is based on a sounding reference signal (SRS) resource, and the spatial parameter for the downlink physical channel is based on a transmission configuration indicator (TCI) state.
