Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a continuation of International Application No. PCT/KR2022/014939 designating the United States, filed on Oct. 5, 2022, in the Korean Intellectual Property Receiving Office and claiming priority to Korean Patent Application No. 10-2021-0135259, filed on Oct. 12, 2021, in the Korean Intellectual Property Office, to Korean Patent Application No. 10-2021-0185418, filed on Dec. 22, 2021, in the Korean Intellectual Property Office, and to Korean Patent Application No. 10-2022-0041841, filed on Apr. 4, 2022, in the Korean Intellectual Property Office, the disclosures of all of which are incorporated by reference herein in their entireties. BACKGROUND Field The disclosure relates to an electronic device and method for wireless LAN communication with a plurality of external electronic devices. Description of Related Art A wireless local area network (WLAN) system may support wireless connection of various electronic devices such as a smartphone, a tablet personal computer (PC), or a notebook, using a designated frequency band (e.g., an approximately 2.4 GHz band, an approximately 5 GHz band, and/or an approximately 6 GHz band). The WLAN system is capable of being installed in public spaces such as airports, train stations, offices, or department stores, in addition to private spaces such as homes. An electronic device may perform wireless local area network (WLAN) communication with a plurality of external electronic devices. For example, the electronic device may perform WLAN communication with a plurality of external electronic devices based on a real simultaneous dual band (RSDB) scheme, a virtual simultaneous dual band (VSDB) scheme, or a single channel concurrent (SCC) scheme. In the case of using the VSDB scheme, the electronic device may perform WLAN communication with a first external electronic device via a designated frequency band during a first time interval, and may perform WLAN communication with a second external electronic device via another frequency band that is different from the designated frequency band during a second time interval that is different from the first time interval. In the case of using the VSDB scheme, the electronic device may perform WLAN communication with external electronic devices during different time intervals, respectively, and thus, latency by WLAN communication may be increased. In the case of the VSDB scheme, the electronic device may be restricted to perform WLAN communication with an external electronic device (e.g., augmented reality glasses) that is relatively sensitive to latency.
