Abstract: Apparatuses, computer readable media, and methods are disclosed for context aware synchronization for peer-to-peer communication. A method may include extracting from a super beacon synchronization information. The method may further include synchronizing with a beacon of an application based on the synchronization information. Another method may include extracting synchronization information from a received beacon, if the received beacon is for a first application. The method may further include if the received beacon is not for a first application, then extracting common beacon synchronization information from the received beacon, scanning for the common beacon based on the extracted common beacon synchronization information, receiving the common beacon, and extracting common channel synchronization information from the common beacon. Another method may include transmitting synchronization information in a data packet to a WTRU, if there is data to be transmitted, and otherwise transmitting synchronization information in a dummy packet to the second WTRU.
