Claim:
1. A method, comprising: performing, by an apparatus, passive scanning on a radio channel during a first time period, wherein the first time period is shorter than a beacon frame transmission period and wherein the first time period is shorter than a fast initial link setup frame transmission period; upon determining, after the first time period, that no discovery frame has been detected on the radio channel during the first time period, determining whether another type of frame, different from a discovery frame has been detected on the radio channel during the first time period; if said another type of frame has been detected on the radio channel during the first time period, determining, by the apparatus, to perform passive scanning on the radio channel during a second time period, wherein the second time period is subsequent to the first time period; and if no frame transmission has been detected on the radio channel during the first time period, determining by the apparatus, to perform active scanning on the radio channel.
