A wireless communication apparatus/system/method utilizing directional data transmission over a communication (e.g., mmW) band and propagating discovery assistance (DA) request and responses to neighboring stations (e.g., in its BSS or in the surrounding area) and performing cooperative discovery with other BSS to increasing network efficiency. Discovery assistance requests include a discovery assistance element and a DMG capability element of the first neighboring station, which is propagated to other stations in the BSS of AP/PCP station.
