Abstract: A 5th generation (5G) and/or pre-5G communication system for supporting a higher data transmission rate than a 4th generation (4G) communication system such as long term evolution (LTE) may be provided. An electronic device, in a wireless communication system, may include: a communication circuit; and at least one processor operatively connected to the communication circuit, wherein the at least one processor is configured to: receive downlink control information (DCI) from a base station; when the DCI does not include information indicating a transmitted precoding matrix indicator (TPMI), and, when a combination of one or more variables indicates a first polarization in a pre-configured table, transmit an uplink signal to the base station by using the first polarization; and, when the combination of the one or more variables indicates a second polarization in the pre-configured table, transmit the uplink signal to the base station by using the second polarization, wherein the one or more variables include at least one of an antenna module, an operating band, or a channel which is used for transmitting the uplink signal.
