1. A first access point (AP) device comprising:
a transmitter associated with a first AP corresponding to a first basic service set identifier (BSSID); and
one or more processors configured to:
generate a frame including information on a target wake time (TWT) schedule scheduled by a second AP corresponding to a second BSSID;
set a first subfield of the frame to indicate whether the first BSSID is the same as the second BSSID;
determine whether the second AP corresponds to an AP in a multiple BSSID set or a neighboring AP in an overlapping BSS (OBSS);
responsive to the second AP corresponding to the AP in the multiple BSSID set, set a second subfield of the frame to indicate that the first BSSID and the second BSSID are included in the multiple BSSID set;
responsive to the second AP corresponding to the neighboring AP in the OBSS, set the second subfield of the frame to indicate that the second AP is the neighboring AP in the OBSS; and
wirelessly transmit, via the transmitter over a wireless local area network (WLAN), the generated frame.
