Millimeter waves support higher frequencies than the waves supported by the 4G communication system, so they have a lower degree of diffraction and have stronger straight-line properties. Due to strong straight-line movement, the communication environment may worsen if an obstacle is located between two electronic devices supporting 5G communication. Accordingly, a cell (or coverage) to support 5G communication can be configured on a smaller scale than a cell to support 4G communication, and relay devices are required to be placed so that there are no obstacles.

According to various embodiments of the present disclosure, in a method of operating an electronic device, each of the first band and the second band is based on a request for carrier aggregation (CA) between the first band and the second band from an external electronic device. For the operation of activating the plurality of antenna modules to form a first beam and a second beam, based on the signal strength of the first beam and the second beam exceeding a threshold, the first band and the For each second band, an operation of forming a third beam and a fourth beam by activating a first antenna module and a second antenna module among the plurality of antenna modules that are not adjacent to each other, and the third beam or the third beam Based on the signal strength of at least one of the four beams not exceeding the threshold, at least one of the first band and the second band such that the signal strength of the at least one beam exceeds the threshold For the band, the method may include forming a fifth beam by activating at least one antenna module including a third antenna module among the plurality of antenna modules.

According to various embodiments, the electronic device 101 may include an output device (eg, an LED indicator). The output device can be controlled to output information about the quality of the communication environment of the electronic device 101. For example, if it is confirmed that the communication environment of the electronic device 101 is good, the LED indicator may output light of a first color (eg, green, blue). For example, if it is confirmed that the quality of the communication environment of the electronic device 101 is poor, the LED indicator may output light of a second color (eg, red).

For example, the first communication circuit 331 may include an intermediate frequency integrated circuit (IFIC), a radio frequency integrated circuit (RFIC), and/or a radio frequency front end (RFFE). IFIC can convert the baseband signal received from the modem into an analog signal and combine it with the signal generated from the PLL (phase-locked loop) circuit to generate a signal in the IF band.

Referring to FIG. 6, in various embodiments, while receiving only signals of the first band as shown in FIGS. 5A and/or 5B, the electronic device receives signals of the first band and the second band from the base station in inter-band CA mode. When receiving a request to receive, the electronic device uses two PLLs (IFIC_PLL0, IFIC_PLL1) in the IFIC to receive the signals of both the first band and the second band, the IF signal of the first band and the IF signal of the second band. A signal can be generated. The IF signal of the first band and the IF signal of the second band generated by IFIC_PLL0 and IFIC_PLL1, respectively, may be input to the input terminals (IF_V and IF_H) of the RFICs connected to each of the four antenna modules.
