1. A method performed by a user equipment (UE) for transmitting an uplink signal in a wireless communication system, the method comprising:
receiving, from a base station, first control information related to a delay value which is applied to precoding for small-delay cyclic delay diversity (CDD);
performing layer mapping complex-valued modulation symbol to at least one transmission layer;
performing the precoding, based on a precoding matrix and a diagonal matrix, for transmitting complex-valued modulation symbol on each transmission layer on an antenna port; and
transmitting, to the base station, the uplink signal,
wherein the diagonal matrix is determined based on the delay value, and
wherein the delay value is determined based on the first control information and second control information which is determined based on a size of a configured band.
