BACKGROUND Field The disclosure relates to electronic devices and integrated control methods of a multi-link operation (MLO) and a restricted target wake time (R-TWT). Description of Related Art The advent of electronic devices such as smartphones, tablet personal computers (PCs), and laptops has brought the explosive demand for high-speed wireless connection. Such a trend and increasing demand for high-speed wireless connection has promoted the firm establishment of the Institute of Electrical and Electronics Engineers (IEEE) 802.11, a wireless communication standard, as a representative and universal high-speed wireless communication standard in the information technology (IT) industry. Early wireless local area network (WLAN) technology that was developed around 1997 supported a transmission rate of 1 to 2 megabits per second (Mbps) to the maximum. It has been steadily developed since then based on the demand for faster wireless connection, and novel WLAN technologies that improve the transmission rate, to this end, standards such as such as IEEE 802.11n, 802.11ac, and 802.11ax, have been developed. IEEE 802.11 ax, which is currently the latest version of the standard, has a maximum transmission rate of several gigabits per second (Gbps). Currently, WLAN covers various public places such as offices, airports, stadiums, or stations in addition to private places such as homes, providing users with high-speed wireless connection throughout society. Accordingly, WLAN has had a significant impact on people's lifestyles and culture and has now become a norm in modern people's lives.
