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.

Abstract: An electronic device includes a first antenna that transmits/receives a signal in a first frequency band, a second antenna that transmits/receives a signal in a second frequency band, a first wireless communication circuit connected with the first antenna, a second wireless communication circuit connected with the second antenna, at least one processor connected with the first and second wireless communication circuits, and a memory. The memory stores instructions that cause the processor to output a first signal with a first power to control the first wireless communication circuit to output the first signal through the first antenna, and output the first signal with a power, which is obtained by backing off from the first power as much as a first backoff value, to control the second wireless communication circuit to output a second signal through the second antenna while controlling the first wireless communication circuit to output the first signal.
