Some demonstrative embodiments include apparatuses, systems and/or methods of Peer to Peer communication. For example, a first wireless device may include a radio to send a first Neighbor Awareness Network (NAN) Service discovery frame including a first Robust peer-to-peer attribute, and to receive from a second wireless device a second NAN Service discovery frame including a second Robust peer-to-peer attribute, the first peer-to-peer attribute including first availability information to indicate at least one first channel and one or more first time slots, the second peer-to-peer attribute including second availability information to indicate at least one second channel and one or more second time slots; and a controller to setup a Robust peer-to-peer connection with the second peer-to-peer device based on the first and second availability information.
