1. An electronic device, comprising:
a communication circuit; and
a processor configured to:
receive, using the communication circuit, from a first external electronic device a synchronization signal related to an uplink (UL) period to be synchronized and a downlink (DL) period to be synchronized, wherein the synchronization signal comprises information indicating the UL period and the DL period of a second external electronic device, and information to set an operation mode of the electronic device to be identical to an operation mode of the second external electronic device included in a neighboring basic service set (BSS),
based on the received synchronization signal, determine the operation mode of the electronic device between a DL operation mode and an UL operation mode,
receive, from a first client device included in the neighboring BSS, a control signal comprising first target wake time (TWT) information of the first client device, and
perform a channel sounding operation with respect to the first client device based on the first TWT information within the UL period and the DL period,
wherein the electronic device comprises a first access point (AP) included in a first BSS, and the second external electronic device comprises a second AP included in a second BSS neighboring to the first BSS, and
wherein a first UL period of the first AP is synchronized with a second UL period of the second AP in the UL period, and a first DL period of the first AP is synchronized with a second DL period of the second AP in the DL period.
