Electronic device comprising frontend module for communicating through wireless LAN

A method of an electronic device comprising a wireless communication circuit, a first frontend circuit connected to the wireless communication circuit, a second frontend circuit connected to the wireless communication circuit, a first antenna connected to the first frontend circuit, a second antenna connected to the second frontend circuit, and a third antenna connected to the second frontend circuit,

• wherein the second frontend circuit is configured to operate in a first operation mode or a second operation mode, wherein the first operation mode is for transmitting or receiving a signal for a wireless local area network (WLAN) and wherein the second operation mode is for transmitting or receiving a signal for a cellular communication;
• wherein the method comprises:
• determining to perform a multi-links operation in a 5 GHz band or a 6 GHz band,
• setting, based on the determination, an operation mode of the second frontend circuit to the first operation mode,
• providing, using the wireless communication circuit, a first signal in the 5 GHz band or the 6 GHz band to the first frontend circuit, and
• while the first signal is being provided to the first frontend circuit and the operation mode of the second frontend circuit is set to the first operation mode, providing, using the wireless communication circuit, a second signal in the 5 GHz band or the 6 GHz band to the second frontend circuit,
• wherein the first signal is transmitted through the first antenna and connected to the first frontend circuit, and
• wherein the second signal is transmitted through at least one of the second antenna or the third antenna.
