An apparatus, computer readable medium, and method for overlapping basic service set (OBSS) indication in a high-efficiency wireless local-area network (HEW). An apparatus of a high-efficiency wireless local-area network device is disclosed. The apparatus including transceiver circuitry and processing circuitry configured to receive a frame and determine whether the frame is a frame transmitted from a basic service set (BSS) or a frame transmitted from an OBSS based on one or more media access control (MAC) addresses of the frame. The MAC address may include an indication of a BSS of the HE wireless device. If the HE wireless device is an access point, then a second part of the MAC address may be a predetermined pattern, the second part of the MAC address may be a formula applied to a first part of the MAC address, or an individual/group bit of the MAC address may be set.
