1. A method for determining a spatial relation for uplink transmission, comprising:
determining a spatial relation for uplink transmission of a first cell by using a first resource in a second cell, wherein the determining a spatial relation for uplink transmission of a first cell by using a first resource in a second cell comprises one of the following:
when the spatial relation for uplink transmission is not configured in the first cell, determining the spatial relation for uplink transmission of the first cell by using the first resource in the second cell;
when the spatial relation for uplink transmission is not configured in the first cell, no CORESET is configured in the first cell, and no TCI-state that is used for transmission of a PDSCH is activated in a downlink bandwidth part currently activated in the first cell, determining the spatial relation for uplink transmission of the first cell by using the first resource in the second cell; or
when the spatial relation for uplink transmission and a reference signal resource for road loss measurement are not configured in the first cell, no control-resource set is configured in the first cell, and no TCI-state that is used for transmission of the PDSCH is activated in the first cell, determining the spatial relation for uplink transmission of the first cell by using the first resource in the second cell; and
performing uplink transmission in the first cell based on the spatial relation for uplink transmission of the first cell.
