Abstract: A method for receiving a signal by a terminal in a wireless communication system according to an embodiment of the present invention can comprise a step for determining REGs, which are to be assumed that the same precoding is used, among REGs comprised in a control resource set on the basis of information relating to precoder granularity, and thus monitoring a control channel candidate. Particularly, if a part of resource blocks overlaps another resource region and particular resource blocks in the resource blocks are no longer contiguous due to the overlapping, the terminal can comprise an assumption that the same precoding is used with respect to the REGs comprised in the particular resource blocks even if the information relating to the precoder granularity corresponds to first configuration.
